Simplify to create an equivalent expression 8(10 - 6q) + 3(7q - 2 )

74-27q

Step-by-step explanation:

8(10 - 6q) + 3(7q - 2)

use the distributive property to get rid of the parenthesis

(8*10) - (8*6q) + (3*7q) - (3*2)

80 - 48q + 21q - 6

combine like terms

(80 - 6) - 48q + 21q

74 - 27q  :)

2 * 3 + 4 * 5 = 26

5 * 7 + 1 * 8 = 43

Step-by-step explanation:

Given

_ * _ + _ * _ = _ _

Required

Fill in the boxes with digits 0 to 9

From the question we understand that the result must be two digits i.e. _ _

To solve this, we'll make use of trial by error method:

Fill the first two boxes wit 2 and 3: _ * _ becomes 2 * 3

Fill the next two boxes with 4 and 5: _ * _ becomes 4 * 5

So,we have

2 * 3 + 4 * 5

6 + 20

26

Hence, the first combination is 2 * 3 + 4 * 5 = 26

Another possible combination is:

Fill the first two boxes wit 5 and 7: _ * _ becomes 5 * 7

Fill the next two boxes with 1 and 8: _ * _ becomes 1 * 8

So,we have

5 * 7 + 1 * 8

35 + 8

43

Hence, another combination is 5 * 7 + 1 * 8 = 43
