Answer:
The rewritten is x + 1.5y.
It can be concluded that Lloyd earns $0.5 per hour more than Harry.
Step-by-step explanation:
Given;
8x + 12y
The expression can be rewritten by dividing it through by 8 as follows:
(8 / 8)x + (12 / 8)y = x + 1.5y
Therefore, the expression can be rewritten as x + 1.5y.
Since x represents the number of hours Harry worked and y represents the number of hours Lloyd worked, the new expression implies that Harry earns $1 per hour while and Lloyd earns $1.5 per hour. Therefore, it can be concluded that Lloyd earns $0.5 per hour more than Harry.

Noah ran 2 1/2 miles in 3/5 hour. How far does he run in 1 hour?
Step-by-step explanation:
0.6 hours = 2.5 miles
=> 1 hour = 2.5 miles * (1/0.6) = 4.16 miles.
Hence Noan runs 4.16 miles in 1 hour.
(or 25/6 miles)

Clara is playing a board game. The game has five cards with a different shape on each card. When a player draws a card, they go to the next spot on the board that has the shape shown on the card. The cards are shown below.
Complete the table by matching the number of trials and the expected frequency for each shape.
Answer: See the attached image below
==============================================
Explanation:
The problem doesn't state this, but I'm assuming we have the same amount of each type of card. For instance, we could have 10 of each card.
The probability of getting any one type is 1/5 = 0.2 since there's one type we're after out of 5 shapes total. If we had 10 of each card, then the probability of getting a diamond is 10/50 = 1/5 = 0.2; note how there are 5*10 = 50 cards total.
If we expect 50 diamonds, then this must mean that 50/0.2 = 250 trials were conducted. You have the correct answer for the first box.
If we do 200 trials, then we expect (1/5)*200 = 40 cards would be a pentagon card. That explains row 2.
If we do 150 trials, then we expect (1/5)*150 = 30 star cards. The value 30 goes in the second box.
The value 300 goes in the third box. We find this by computing 60/0.2, or we can multiply 5 by 60. Note how (1/5)*300 = 60.
Lastly, if we conduct 50 trials, then we expect 10 circle cards because (1/5)*50 = 10.
Side note: the values 100 and 20 are not used.
Factor the expression.

O A
(4x + 7)(4x - 7)
B. (7x + 4)(7x-4)
C. (7x-4)(7x-4)
OD. (4x-7)(4x - 7)
Step-by-step explanation:
Difference of squares: A² - B² = (A + B)(A - B).
Therefore 49x² - 16 = (7x)² - (4)² = (7x + 4)(7x - 4).
The correct answer is Option B.

What is the slope of the line graphed on the coordinate plane?
Put your answer in the box
Answer:
-8
Step-by-step explanation:
As we know, slope is rise over run. We count up and over until we get to the next dot. To get to the next dot, we count 8 up and -1 over (since we go to the left, not the right). We can put this in a fraction (rise/run). That gets us 8/-1, which can be simplified to -8.

Susan is making a large batch of salsa.
She can spend no more than $30 on ingredients. She buys all ingredients except for tomatoes for $6.50. Tomatoes cost $2 per pound.
How many pounds of tomatoes,x, can she buy?
INEQUALITY THAT REPRESENTS THIS SITUATION
30>= 6.50+2x
Answer:
She can buy 0 to 11.75 pounds of tomatoes.
Step-by-step explanation:
Consider the provided information.
It is given that Susan can spend no more than $30 on ingredients. She buys all ingredients except for tomatoes for $6.50. Tomatoes cost $2 per pound.
It means she can only spend less than or equal to $30. Let x be the pounds of tomatoes she can buy.
So, the required inequality should be:
[tex]30\leq 6.50+2x[/tex]
Now simplify the inequality.
[tex]30-6.50\leq 2x[/tex]
[tex]23.5 \leq 2x[/tex]
[tex]11.75\leq x[/tex]
Hence, she can buy 0 to 11.75 pounds of tomatoes.

a triangle has the side lengths of 7.5 and 4.8, what is the range of lengths for the third side
Answer:
2.7 < x 12.3
Step-by-step explanation:
using triangle inequality theorem:
(3 scenarios, discount the one that produce a negative)
4.8 + 7.5 > x x < 12.3
4.8 + x > 7.5 x > 2.7
7.5 + x > 4.8 (discount)

Which expression is equivalent to 2(x + 7) - 2(9x - 0.4)?
A -16x + 13.2
B -16x + 14.8
C -16x + 14.8
D -16x + 14.8
Answer:
-16x+14.8
Step-by-step explanation:
2(x+7)-2(9x-0.4)
2x+14-18x+0.8
-2x+14-18x+0.8
14-16x+0.8
14+0.8-16x
14.8+-16x
Choose the best method to solve the system of linear equations. Then choose a reason to justify your answer choice. x−3y=6 x−3y=−3
Answer:
No solution.
Step-by-step explanation:
The given equations are :
x−3y=6 ...(1)
x−3y=−3 ...(2)
We need to solve the above equations.
The above two lines are parallel. Forparallel lines,
[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\ne \dfrac{c_1}{c_2}[/tex]
Here,
[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}[/tex]
It means, the above equations have no solution.
Which sentence best describes the equation: z = 18 + 96

Papa John's sold 236 pizzas last night. The manager wants to give the workers a prize if they can increase the number of pizzas sold by 24%. How many pizzas do they need to sell to get the prize? (Remember if there is a decimal to round up to the next whole number so 13.2 would become 14)
Answer:
You need to increase the amount of pizza sold by 24%, you can do it one of two ways:
236*0.24 = 56.64 and then do 236 + 56.64 = 292.64
(this way you find out what 24% of 236 is and then add it to 236 to get an increase of 24% )
or you can do this:
236 *1.24 = 292.64
(this way you're finding out what 124% of 236 is. I find this way easier because there's less steps. it works because you're still finding out what 24% is, you're just keeping the 236 there)
either way they need to sell 293 pizza's to get the prize

Step-by-step explanation:
Z + y + 0 = z + y equals to what?
Answer:
y=0/0
Step-by-step explanation:
Step 1: Add -y to both sides.
y+z+−y=y+z+−y
z=z
Step 2: Add -z to both sides.
z+−z=z+−z
0=0
Step 3: Divide both sides by 0.
0/0=0/0
y=0/0
In Mr. Romero's auto shop class, the ratio
of boys to girls is 5:2. If there are 35 students
in the class, how many are boys?
Answer:
boys 5:2 girls
add the ratio parts together
5 + 2 = 7
divide the total number of students by the total number of parts
35/7 = 5
now multiply each part of the ratio by 5
boys 25
girls 10
there are 25 boys
Find the perimeter of a 35° slice of pizza that has a radius of 8 inches.
9514 1404 393
Answer:
20.9 inches
Step-by-step explanation:
The perimeter length is the sum of the lengths of the two straight edges and that of the curved edge.
P = r + r + rα . . . . . where α is the central angle in radians
35° is (35°/180°)π radians, about 0.6109 radians
Then the perimeter is ...
P = r(2 +α) = (8 in)(2 +0.6109) ≈ 20.9 in
The perimeter of the slice is about 20.9 inches.
