Answer:
are there choices?
Step-by-step explanation:
<h2>1.</h2>
Firstly, combine like terms: 
Next, subtract r on both sides of the equation: 
Next, add 8 onto both sides of the equation: 
Lastly, divide both sides by 6 and <em><u>your answer will be r = 3.</u></em>
<h2>2.</h2>
Firstly, multiply both sides by e: 
Lastly, divide both sides by 3, and <em><u>your answer will be
</u></em>
Answer:
7) a = 60; b = 100
8) c = 20
9) d = 45
Step-by-step explanation:
7)
a + 120 = 180
a = 60
b + 80 = 180
b = 100
8)
5c + 4c = 180
9c = 180
c = 20
9)
3d + d = 180
4d = 180
d = 45

Step-by-step explanation:
1.5x(-2-33)=5x-35=5(35:5)=5(x-7)
2.140+36=176/176-4x=4(44-x)
A function is a relation that associates each element x of a set X, to a single element y of another set Y.
Circle is not a function of x. For x = 0 we have y = -7 and y = 7.
