Answer:
-7
Step-by-step explanation:
-4(2)=-8
-8+1=-7........
Step-by-step explanation:
9x+6+5x+90°= 180°
14x+96=180
14x=180-96
14x=84
x= 84/14
x=6
so, <A=5x=5(6)=30°
<B=9x+6=9(6)+6=54+6=60°
<C = 180-(30+60)=180-90=90°
So a dime is .10 or 10 cents
a quarter is .25 or 25 cents
12(.10)=$1.2
4(.25)=1
the equations would be
.25(x)
.10(x)
and if you need them combined it would be
.25(x) + .10(x)

-3+3x=-2(x+1)
First: I will get rid of the bracket:
-3+3x=-2x-2
Now, all the x goes to the left side, all the numbers without x to the right side:
3x+2x=-2+3
we add up"
5x=1
divide by 5:
S^2 + s^2 = 9^2 => 2s^2 = 81 => s^2 = 81/2 => side length s = 9(sqrt(2))/2 = 6.37 cm.
