Kory bought 2 boxes of candy and 1 soda at the movies and paid $8.00.christopher bought 1 box of candy and 1 soda and paid $5.50

viva [34]

Let c represent candy and s soda.
2c+s=8
c+s=5.5
Solving the pair of simultaneous equations by eliminating s,
c=2.5
Representing the value of c in equation 1;
5+s=8
s=3
So, a box of Candy costs 2.5 and a soda costs 3

If c = d and b ≠ 0, then c∕b = d∕b represents the property of equality. Question 4 options: A) division B) multiplication C) add

sergejj [24]

Answer:

Property of equality division

Step-by-step explanation:

Given

c = d

b ≠ 0 then c∕b = d∕b

Required

State the property used

From list of options a through d, only option A best fits the description.

This is so because property of equality division is such that

given two variables c and d where c = d

$\frac{c}{b} = \frac{d}{b}$

Provided that b ≠ 0

Take for instance;

b = 2; c = 8 and d = 8;

This implies that

$c = d$

$8 = 8$

Divide both sides by 2 (assumed value of b)

$\frac{8}{2} = \frac{8}{2}$

$4 = 4$

How to do: 4(x+7)=2(x+7)

andre [41]

4(x+7) becomes 4x+28 you multipli the 4 in parentheses ans 2(x+7) becomes 2x+14

4x+28=2x+14 you move the x termes to the left and other numbers to the right look:

4x-2x=14-28 when you change the sides always change the sign +or-
2x=-14
2x/2=-14/2
X=-7
