Answer:

What is the relationship between equations and graphs?

Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).

pochemuha

Answer:

$\huge\boxed{x=18^o}$

Step-by-step explanation:

Two angles are Complementary when they add up to 90°.

Therefore

$x+4x=90\qquad|\text{combine like terms}\\\\5x=90\qquad|\text{divide both sides by 5}\\\\\dfrac{5x}{5}=\dfrac{90}{5}\\\\\boxed{x=18}$

The standard recipe for Hershey’s chocolate is 2/9 cups cocoa and 1/6 cups milk. If Hershey’s decided to pour a total of 14 cups

olya-2409 [2.1K]

Ok so if I understand this correctly then you have to find out what each one of them are then add them to get the total number of both of them. So this is the equation I did. The one circled on blue is the formula I made for the equation and then the green one is the answer. which is 5 4/9

I hope this helps.

Which will equation show correctly we write an expression that represents the cost for a pair of shoes that is marked down 20% o

alukav5142 [94]

Answer:

Step-by-step explanation:

You can write an expression to represent the total cost of a pair of shoes. The price of the shoes is the variable r. The shoes are marked down 20% or 0.2r. So the new price of the shoes will be r - 0.2r. You will also have to pay a tax of 5% or 0.05 of the new price. This is written as 1.05(r - 0.2r). You can simplify it by doing whats in the parenthesis.

1.05(r - 0.2r) = 1.05r(0.8r) = 0.84r
