Answer:
1.50
Step-by-step explanation:
8 x 1.50=12
25-12=13
13-4=9
9/6=1.5
The answer is 4605 feet since 921 • 5 is 4605. There are 5 sides and each side 921 so 921 • 5 = 4605 would be the answer
-2x + 7y = 10 ⇒ -2x + 7y = 10
x - 3y = -3 ⇒ <u>-2x + 6y = 6 </u>
y = 4
-2x + 7(4) = 10
-2x + 28 = 10
<u> -28 -28</u>
<u>-2x</u> = <u>-18</u>
-2 -2
x = 9
(x, y) = (9, 4)
4=2+25t
We move all terms to the left:
4-(2+25t)=0
We add all the numbers together, and all the variables
-(25t+2)+4=0
We get rid of parentheses
-25t-2+4=0
We add all the numbers together, and all the variables
-25t+2=0
We move all terms containing t to the left, all other terms to the right
-25t=-2
t=-2/-25
t=2/25
