Answer:
117
Step-by-step explanation:
Given
72 ÷ 8 + 4y³ with y = 3, substitute y = 3 into the expression
= 72 ÷ 8 + 4 × 3³ ← evaluate exponent
= 72 ÷ 8 + 4 × 27 ← evaluate division and multiplication
= 9 + 108 ← calculate addition
= 117
Answer: a
Step-by-step explanation:
Answer:
x = 14
Step-by-step explanation:
If the perimeter is 80, then that is (x+6) + (x+6) + (x+6) + (x+6). If you want to find x, you have to get rid of 6. 6+6+6+6 = 24. The perimeter, 80, minus 56. You then divide 56 by 4 to get x. That is 14. To check, you find (14+6)*4. That is 80.
Answer:
They had 1,352 marbles all together, rounded to the nearest hundred, 1,400.
Step-by-step explanation:
All we have to do is add the number of marbles they collected.
510 + 842 = 1,352
1,352 rounded to the nearest hundred is 1,400.
You would write the equation out as x=35x+500
You substitute x for 7 so it’s x= 35(7)+500
So the answer will be 745 dollars
