Answer:
x=32
Step-by-step explanation:
first, you add 64 to both sides and you have: x2=64
second, you divide 2 on both sides to get x by itself, so 64 divided by 2 is 32
Answer:
a) $86.11
b) $467.33
Step-by-step explanation:
no. of gallons saved 'n' per year
n = (10000/33) - (10000/36)
n = 2500/99
Amount saved = 3.41×n = 3.41×2500/99
= $86.11
b) over 5 years:
86.11( 1 + (1.041) + (1.041)² + (1.041)³ + (1.041)⁴ )
= 86.11(5.427157431)
= $467.33
I got -3.........................
-7 - 7p = 3p + 23
Move the -7p over to the right....by adding
-7 = 10p +23
Move the 23 over to the left by subtracting
-30 = 10p
divide by 10
p = -3

Answer:
First angle: 27
Second angle: 135
Third angle: 18
Draw a triangle with one obtuse angle and 2 acute angles.
Step-by-step explanation:
<u>Determine the variables</u>:
first angle: f
second angle: s
third angle: t
<u>Write an equation for the second angle:</u>
s=5f
<u>Write an equation for the third angle:</u>
t=2/3f
<u>Write an equation for the total angle measurements:</u>
s+t+f=180
<u>Substitute them and solve</u>
5f+2/3f+f=180
f=27
5(27)=135=s
2/3(27)=18=t
First angle: 27
Second angle: 135
Third angle: 18
