Answer:
21
Step-by-step explanation:
Using inequality to solve this question, we say
Let the total number of newspapers sold be x
Let the total number of magazines sold by y
x + y = 68
Suppose 1x = $2 and 1y = $5, then
2x + 5y = $199
Solving both as a simultaneous equation, we get that
2(68 - y) + 5y = $199
136 - 2y + 5y = $199
136 + 3y = $199
3y = 199 - 136
3y = 63
y = 63/3
y = 21
Then solving for x, we have
x + 21 = 68
x = 68 - 21
x = 47
Therefore, a total of 21 magazines were sold that day
Which pair shows equivalent expressions?2(3x+ 2) = 23 x+1
21ę x+ 2) = x+4
2c
21= x+4)= 2
Answer:
Option (2)
Step-by-step explanation:
Option (1).
[tex]2(\frac{2}{5}x+2)=2\frac{2}{5}x+1[/tex]
[tex]\frac{4x}{5}+4=\frac{12}{5}x+1[/tex]
Therefore, both the sides of the expression are not equal.
False.
Option (2).
[tex]2(\frac{2}{5}x+2)=\frac{4}{5}x+4[/tex]
[tex]\frac{4x}{5}+4=\frac{4}{5}x+4[/tex]
True.
Option (3).
[tex]2(\frac{2}{5}x+4)=\frac{4}{5}x+2[/tex]
[tex]\frac{4}{5}x+8=\frac{4}{5}x+2[/tex]
False.
Option (4).
[tex]2(\frac{2}{5}x+4)=2\frac{2}{5}x+8[/tex]
[tex]\frac{4x}{5}+8=\frac{12}{5}x+8[/tex]
Both the sides are not equal.
False.

Which of the following is equivalent to the expression 8/3 - 5/6 - 2/12
Group of answer choices
1_2/3
14_2/3
2
13_1/3
Given:
The expression is
[tex]\dfrac{8}{3}-\dfrac{5}{6}-\dfrac{2}{12}[/tex]
To find:
The expression which is equivalent to the given expression.
Solution:
We have,
[tex]\dfrac{8}{3}-\dfrac{5}{6}-\dfrac{2}{12}[/tex]
It can be written as
[tex]=\dfrac{8}{3}-\dfrac{5}{6}-\dfrac{1}{6}[/tex]
Taking LCM, we get
[tex]=\dfrac{16-5-1}{6}[/tex]
[tex]=\dfrac{10}{6}[/tex]
[tex]=\dfrac{5}{3}[/tex]
The mixed fraction of this improper fraction is
[tex]=\dfrac{1\times 3+2}{3}[/tex]
[tex]=1\dfrac{2}{3}[/tex]
So, the expression [tex]1\dfrac{2}{3}[/tex] is equivalent to the given expression.
Therefore, the correct option is A.

Hello!
[tex]slope = 2\\\\y-intercept = (0, 3)\\\\Equation: y = 2x + 3[/tex]
We can find the slope using the slope formula:
[tex]slope = \frac{y_{2} - y_{1}}{x_{2}-x_{1}}[/tex]
Plug in any two points from the table. We can use (0, 3) and (1, 5):
[tex]slope = \frac{5 - 3}{1-0}[/tex]
[tex]slope = 2[/tex]
Now, we can find the y-intercept by finding the y-value at which x = 0.
According to the table, when x = 0, y = 3. Thus, the y-intercept is:
[tex](0, 3)[/tex]
We can write an equation using the slope and y-intercept in the format
y = mx + b where "m" is the slope and "b" is the y-intercept.
Plug in the solved values into the equation:
y = 2x + 3.

There are 124 pages in a sketchbook. John used 36 pages. Miss Hamilton asks him to draw 2 pictures each week. How many weeks does John take to finish the sketchbook? Step by step explanation pls.
Answer:
44 weeks
Step-by-step explanation:
First, he’s already used 36 pages so he has 124-36=88 pages left to use.
Since he can use 2 pages per week, by dividing 88(# of pages left) by 2( pages per week), you will get the answer. 88÷2=44 weeks

Answer:
1.25, 40
1.6, 30
Step-by-step explanation:
First, we'll state that the lbs of candy worth $1.25 is A and the lbs of candy worth $1.6 is B.
We write the equations: A + B = 70, (This is the lbs)
and, 1.25A + 1.6B = 1.4(70) (This is money)
Next, choose an equation you want to solve for, in this case, I'll choose A.
In the lbs equation, subtract A from both sides, A - A + B = 70 to get B = 70 - A
Now substitute this equation into the money equation.
1.25A + 1.6(70 - A) = 98
1.25A + 112 - 1.6A = 98
-0.35A = -14
multiply by negative
0.35A = 14
divide
A = 40
Then, you substitute 40 into the lbs equation, 40 + B = 70, making B = 30! Done!

Paul has a sum of $260 in $5 and $10 bills. If he has 40 bills in total, how many were of each denomination?
Answer:
28 5 dollar bills
12 10 dollar bills
Step-by-step explanation:
You can write two equations to model this situation'
x will be the number of 5 dollar bills
y will be the number of 10 dollar bills
x+y=40
5x+10y=260
There are a couple of ways you can solve this but but I will be doing it through substitution because that looks easier (I can explain other methods if you're interested)
So we have x+y=40
If I subtract y from both sides and divide by -1 we get
-x+40=y
We can then plug this value in for y in the second equation
5x+10(-x+40)=260
Distribute the 10 and combine like terms to get
-5x+400=260
subtract 400 from both sides and divide by -5 to get
x=28
This means that there are 28 5 dollar bills. We can plug this value back in for x into our first equation to solve for y
28+y=40
Subtract 28 from both sides
y=12
This means that there were a total of 28 5 dollar bills and 12 10s

Answer:
(a/2, a/2)
Step-by-step explanation:
Coordinates of B & D are; (0, a) and (a, 0) respectively.
The formula for calculating coordinates of midpoint is;
M = ((x1 + x2)/2), ((y1 + y2)/2)
Coordinates of BD will be;
M_BD = ((0 + a)/2), ((a + 0)/2)
M_BD = (a/2, a/2)

Complete question :
Jeremiah plans on building a 5 meter long garden walkway that is paved with square stones that measure " 5/6 meter on each side. There will be no spaces between the stones. How many stones will be needed to complete the garden walkway?
Answer:
12
Step-by-step explanation:
Given that:
Length of square block to be used = 5/6 meters
Length of garden. Walkway = 5 m
Since length of walkway is the same on both sides, then the Total length = 5m + 5m = 10 meters
Number of square stones required :
Total length of walkway / side length of stones to be used
= 10 meters ÷ (5/6) meters
= 10 * 6/5
= 60 / 5
= 12 stones
