Which expression is equivalent to 3(8 + 7)? So i did do the math and 3x8+7 is 55 24 + 7 (i got 31)
24 + 21 ( i got 45, but i did it again using the butterfly method and got 55 so i feel like this might be it i am just not sure and want someone to correct me before its too late)
11 + 10 ( i got 21)
11 + 7 (i got 18)

24 + 21

Step-by-step explanation:

Remember the distributive property :) You want to multiply 3 by both 8 and 7.

3(8+7)

= (3 x 8) + (3 x 7)

= 24 + 21

= 45

Check using order of operations:

BEDMAS or PEDMAS

(parentheses/brackets, exponents, division or multiplication depending on which comes first left to right, addition and subtraction depending on which comes first left to right)

3(8 + 7)

= 3(15)

= 45

answer: sorry i can't you.

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
