A car travels 374 meters in 17 seconds. A bud travels 415?meters in 23 seconds. Which vehicle is traveling faster? How much faster?
Answer: Distance traveled in one second by car = 374 ÷ 17= 22 meters
Step-by-step explanation:
Distance traveled by bus in one second = 414 ÷ 23 = 18 meters. Car travels faster. It travels 4 meter more in one second than Bus.

Which two steps should be used first in solving the system of equations by substitution?
A:Substitute 9 for y in the first equation and then solve the other equation for x.
B:Solve the second equation for y and then substitute this value into the first equation.
C:Subtract the terms in the second equation from the first equation and then solve for y
D:Multiply the first equation by 4 and the second equation by 2.
Answer:
B because that is how you do substitution and all of the other ones do not make sense
Clifford works 40 hours per week while working as a laboratory technician. He earns $453.60 for each week of work.
How much money does he earn in 1 hour?
How much money does he earn in 10 hours?
Answer:
he makes $11.34 and hour and $113.40 in 10 hours
Step-by-step explanation:
you divide 453.6 by 40 to get the 1 hour part and then divide it by 4 to get the 10 hour part
The amount of money that he earns in one hour and in 10 hours will be $11.34 and $113.4, respectively.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Clifford works 40 hours per week while working as a laboratory technician. He earns $453.60 for each week of work.
The amount of money that he earns in each hour is given as,
Rate = $453.60 / 40
Rate = $11.34 per hour
The amount of money that he earns in 10 hours is given as,
⇒ $11.34 x 10
⇒ $113.4

What does this equal:
X=3 and Y=
What does Y equal if X is 3?
Please help me
No picture included
Answer:
3
Step-by-step explanation:
What we can see from your table is that as x goes up by 1 y goes down by one
This means that the slope is -x
We also see that when x=0 y=6 which means that the y intercept is 6
this means your equation is
-x+6
We can now plug in x for 3 and get
-3+6=y
y=3
the answer is 3
What are two fractions that are equivalent to 5/20?
find values of x and y??
9514 1404 393
Answer:
x = 80y = 122Step-by-step explanation:
The angles marked with x-expressions are complementary, so ...
(3/4x -2) + (2/5x) = 90
x(3/4+2/5) = 92 . . . . . . . add 2
x(23/20) = 92 . . . . . . . . combine the fractions
x = 92(20/23) . . . . . . . . multiply by 20/23
x = 80
__
The angle marked y° is a vertical angle with the angle that is the sum of 90° and (2/5x)°. So, the value of y is ...
y = 90 + 2/5(x) = 90 +2/5(80) = 90 +32
y = 122

What product is shown by the model. (15 Points)
Answer:
100
Step-by-step explanation:
So in this problem, we have 5 base 10 blocks and 50 ones.
To find out the product we have to count by tens:
10, 20, 30, 40, 50
So 5 base 10 blocks = 50
Now we add the base ten blocks and the ones together:
50 + 50 = 100
So the answer is 100
If Sawyer charges $20 per bottle of water and a flat fee of $25 even to discuss a sale, which of the following equations expresses Sawyer's total fees for "X" bottles of water? * A. y = 25x + 20 B. y = 20x + 25 C.y = 45x D.y = x + 25
Answer:
y =20 x + 25 (answer B in the list of options)
Step-by-step explanation:
y = 25 + 20 x = 20 x + 25
being 25 the flat fee and 20 the price per bottle
Answer:
B. y = 20x + 25
Step-by-step explanation:
The flat fee of $25 is our b, and the fee of $20 is our m. When we put this in slope intercept form, it looks like y = 20x + 25. That means B is the correct answer.

[tex]\dfrac{5}{2}\left(k-\dfrac{4}{5}\right)[/tex]
Step-by-step explanation:
When you factor out 5/2, each term gets divided by 5/2. Equivalently, each term is multiplied by 2/5.
[tex]\dfrac{5}{2}k-2=\dfrac{5}{2}\cdot\dfrac{2}{5}\left(\dfrac{5}{2}k-2\right)=\dfrac{5}{2}\left(\dfrac{2}{5}\cdot\dfrac{5}{2}k-\dfrac{2}{5}\cdot2\right)\\\\ =\boxed{\dfrac{5}{2}\left(k-\dfrac{4}{5}\right)}[/tex]

Answer:
The system of equations is given as:
x + y = 2.5 .... Equation 1
1.8x + 1.8y = 4.05....Equation 2
Step-by-step explanation:
Kiran says, "I bought 2.5 pounds of red and yellow lentils. Both were $1.80 per pound. I spent a total of $4.05
Let
x represent red lentils
y represent yellow lentils.
x + y = 2.5 .... Equation 1
x = 2.5 - y
$1.80 × x + $1.80 × y = $4.05
1.80x + 1.80y = 4.05....Equation 2
The system of equations is given as:
x + y = 2.5 .... Equation 1

Harold Crispen worked Monday, Tuesday, and Thursday from 9:00 A.M. to 4:30 P.M. with a half hour lunch each day. What were his total hours worked? 21 22.5 30 28
Answer:
His total hours he worked is;
21
Step-by-step explanation:
The of hours between 9:00 A.M. and 4:30 P.M. are;
[tex]\begin{array}{ccc}From \ 9:00 \, A.M. & to \ 10:00\, A.M. & = 1 \, Hour\\From \ 10:00 \, A.M. & to \ 11:00\, A.M. & = 1 \, Hour\\From \ 11:00 \, A.M. & to \ 12:00 \, P.M. & = 1 \, Hour\\From \ 12:00 \, P.M. & to \ 1:00 \, P.M. & = 1 \,Hour\\From \ 1:00 \, P.M. & to \ 2:00 \, P.M. & = 1 \,Hour\\From \ 2:00 \, P.M. & to \ 3:00 \, P.M. & = 1 \,Hour\\From \ 3:00 \, P.M. & to \ 4:00 \, P.M. & = 1 \,Hour\\From \ 4:00 \, P.M. & to \ 4:30 \, P.M. & = 0.5 \, Hour \end{array}[/tex]
Sum of the hours Harold Crispen spends at the workplace on a workday = (1 + 1 + 1 + 1 + 1 + 1 + 1 + 0.5) hours = 7.5 hours
The time Harold Crispen take for launch each workday = 0.5 hour
The number of hours Harold Crispen spend working each day = (7.5 - 0.5) hour
The number of hours Harold Crispen spend working each day = 7.0 hours/day
The number of days he worked = Monday + Tuesday + Thursday = 3 days
The total hours he worked = (The number of hours he works each day) × (The number of days he worked)
His total hours he worked = 7.0 hours/day × 3 days = 21.0 hours.
track team ran 8 in one day? miles (mi) in 5 days. If they ran the same distance each day, how far did they run?
Answer:
d = 1.75 miles
Step-by-step explanation:
A track team ran 8 and 3/4 miles in 5 days.
We need to find the distance covered by it each day. Let the distance is d.
[tex]8\dfrac{3}{4}[/tex] miles in 5 days
or
[tex]\dfrac{35}{4}[/tex] miles in 5 days.
[tex]1\ day=\dfrac{\dfrac{35}{4}}{5}\\\\=1.75\ \text{miles}[/tex]
So, each day the team will cover 1.75 miles.

The area of this rectangle is 8cm2
(3x + 1) cm
(2x + 5) cm
Work out the value of x
Answer:
The value of [tex]x = \frac{1}{6}[/tex]
The length of the rectangle [tex]= \frac{3}{2}[/tex] cm
The width of the rectangle = [tex]\frac{16}{3}[/tex] cm
Step-by-step explanation:
Step(i):-
Given that area of the rectangle = 8 cm²
Length of the rectangle (l) = 3x+1
width of the rectangle (w) = 2x+5
The area of the rectangle = length × width
Given that area of the rectangle = 8 cm²
Step(ii):-
Now
(3x+1) ( 2x+5) = 8
⇒ 3x(2x+5) +1(2x+5) =8
6 x² + 15x + 2x +5 =8
⇒ 6 x² + 17x -3 =0
⇒ 6 x² + 18x -x -3 =0
⇒ 6 x ( x+3) -1(x+3) =0
⇒ 6x -1 =0 and x +3 =0
[tex]6x = 1[/tex] and x =-3
[tex]x = \frac{1}{6}[/tex]
The length of the rectangle
[tex]= 3 (\frac{1}{6} ) +1 \\= \frac{3}{2}[/tex]
The width of the rectangle
[tex]= 2 (\frac{1}{6} ) +5[/tex]
= [tex]\frac{16}{3}[/tex]

A handful of coins has the value of 1 dollar and 79 cents. There are three times as many dimes as quarters, and five more pennies than dimes. If there are only three types of coins, how many coins of each type are there?
Answer: There are 3 quarters , 9 dimes and 14 pennies.
Step-by-step explanation:
Let x= Number of quarters
Then, Number of dimes = 3x
Number of pennies = 3x+5
1 quarter = $ 0.25
1 dime = $0.10
1 penny = $ 0.01
So, Total amount = 0.25x+ 0.10(3x) + 0.01(3x+5)
= 0.25x+0.30x+ 0.03x+0.05
= 0.58x+0.05
Since Total amount = 1 dollar and 79 cents = $ 1.79 [1 cent = $ 0.01]
So,
[tex]0.58x+0.05=1.79\\\\\Rightarrow\ 0.58x= 1.74\\\\\Rightarrow x=\dfrac{1.74}{0.58}\\\\\Rightarrow x=3[/tex]
Thus, there are 3 quarters , 9 dimes , 14 pennies.
Answer:
Step-by-step explanation:
there are 3 quarters , 9 dimes , 14 pennies.
