The statement that correctly calculates the average price of Will's books is
B. ($32 + $45 + $39) ÷ 3
This is because the average or mean, is found by adding all of the numbers together and then dividing the sum by the amount of numbers you added together (in this case 3.)
Answer:
Left apples = 2
Step-by-step explanation:
The given problem is "If pierino has 4 apples and eats two, what is left".
Total no of apples = 4
He eats 2 apples = 2
We need to find no of apples left.
Left apples = total no of apples - eaten apples
= 4 - 2
= 2
Hence, there are 2 apples left.
Answer:
Each shirt costs 12 dollars.
Each pair of pants cost 40 dollars.
Step-by-step explanation:
<u>Let x represent the shirts </u>
<u>Let y represent the pair of jeans</u>
10x + 4y = $280
12x + 5y = $344
<u>Use elimination method to eliminate y</u>
• Multiply the entire first equation by 5.
• Multiply the second entire equation by -4.
5(10x +4y = $280)
-4(12x + 5y = $344)
50x + 20y = 1400
-48x -20y = -1376
2x = 24
x = 12
Each shirt costs 12 dollars.
<u>Solve for how much each pair of jeans costs.</u>
10(12) + 4y = 280
120 + 4y = 280
4y = 160
y = 40
Answer:
A
Step-by-step explanation:
trust
Solution: x=5, top angle=80, bottom angle=100
Step by step solution:
Since they are same side interior angles they are equal to 180 so we can set up an equation.
19x+5+17x-5=180
36x=180
x=5
Then plug in the x value in the original equations
19(5)+5=20(5)=100
17(5)-5=16(5)=80
Hope that helps :)
