Answer:
X=9/4
Step-by-step explanation:
-3x+10=5x-8
Subtract 10 from each sides
-3x=5x-18
Subtract 5x from both sides
-8x=-18
Divide both sides by -8
x=9/4

Answer:
-65 i suppose
Step-by-step explanation:
Let one angle be x
Let second angle be 88+x
Sum of two complementary angles = 90°
x+ 88+ x = 90°
2x + 88 = 90
2x = 90 - 88 = 2
x = 2/2 = 1
First angle = x = 1°
Second angle = 88 + x = 88+1 = 89°

Answer:
c = 150p + 1000
Step-by-step explanation:
We know the variable cost is 150 per phone, so the total cost will be ...
c = 150p +b . . . . for some value b
We also know the value of c for 8 phones, so we can find b:
2200 = 150(8) + b
2200 -1200 = b = 1000
Then the desired equation is ...
c = 150p + 1000
Well you can simplify them by dividing by there greatest common factor.
In this case they can both divide by 12!
Thats the biggest number they can divide by...
Soo..
36 ÷ 12 = 3
----------------
48 ÷ 12 = 4
So your answer is 3/4!
Good Luck! :)
