The sum of a number (n) and 14 is 72. Which equation shows this relationship

2 answers:

7 0

This problem states that we need to find the value of 'n'. To make an equation out of this simply put the 'n' (or x, if you prefer) where that value would normally go.

Doing this gives you: n + 14 = 72

I know you don't need this but for reference, 'n' would equal 58 in this problem.

How do you read this expression 8(8x+7) and 8(3x)+8(7)

Misha Larkins [42]

Answer:

64x+56 & 24x+56

Step-by-step explanation:

I hope this is what you mean because this is not an equation as it is not set equal to anything.

Both problems solved by distributive property -

8*8x + (8*7) = 64x+56

8*3x + (8*7) = 24x+56

Braden has $75 to spend for t shirts online. If shipping is $3 , how many " t" t shirts can he buy if theshirts cost $ 8?

inysia [295]

Answer:

9 tshirts

Step-by-step explanation:

Money he had for t shirts= $75

Cost of shipping= $3

Money left for t shirts= $75-$3=$72

Cost of 1 t shirt= $8

We can find the answer with two ways:

1st way: tshirts of $8=1

tshirts of $72=72/8

=$9

2nd way: Cost ($) 8 72

T shirts 1 x

8/1=72/x

by cross multiply

x=72/8

x=9
