Answer:

I believe the answer is X=40

Step-by-step explanation:

cross multiply 5*16 = X * 2

Multiply 5*16

80= X*2

Add '-2x' to each side of the equation

80 + -2x = 2x + -2x

Combine like terms

80 + -2x = 0

Add '-80' to each side of the equation.

80 + -80 + -2x = 0 + -80

Combine like terms: 80 + -80 = 0

0 + -2x = 0 + -80

-2x = 0 + -80

Combine like terms: 0 + -80 = -80

-2x = -80

Divide each side by '-2'.

x = 40

Simplifying

x = 40

Hope this helped :)

A sandwich shop charges $3.75 for a sandwich with meat and cheese and $0.15 for each additional topping. You can spend at most $

zimovet [89]

Answer:

3.75 + 0.15n ≤ 5.25

Step-by-step explanation:

You can not spend more than $5.25 so the inequality sign must be less than or equal to

If you know the shop charges a minimum of $3.75 for a sandwich, you need to include that in your equation

The $0.15 for additional toppings is included as $0.15 multiplied by n (0.15n)

n can be from 0-10, as 10 is the most toppings you can get before you go over your spending limit and you don't have to pay for additional toppings if you don't want to.

Chloe purchased a sweater that cost $24, and a shirt that cost 5/8 times as much as the sweater.What amount of change did Chloe

KatRina [158]

Answer:

Chloe received $11 as change if she gave the clerk $50

Step-by-step explanation:

We are given that Chloe purchased a sweater that cost $24, and a shirt that cost 5/8 times as much as the sweater.

Cost of sweater = $24

Cost of shirt = $\frac{5}{8} \times 24 = 15$

So, Total cost of shirt and sweater = 24+15=39

Now She gave $50 to clerk

So, Change received by her = 50-39=11

So, Chloe received $11 as change if she gave the clerk $50
