Step-by-step explanation:
y=mx+c
3x-2y+4=0
-2y=-3x+4(divide all sides by -2)
<h2> =y=3/2x-2</h2>
All you have to do here is some simplifying.
6/12 = what
6 divided by 12 = 1/2
1/2 = 2/4
There! We have our missing value
6/12 = 2/4
Answer: c = 4
Step-by-step explanation:
(3²)² x (10³)²
=3^4 x 10^6
=81 x 1000000
=81000000
x+x+90=180
x+x+90=1802x+90=180
x+x+90=1802x+90=1802x=180-90
x+x+90=1802x+90=1802x=180-902x=90
x+x+90=1802x+90=1802x=180-902x=902x/2x =90/2
x=45
9y+9y+90=180
18y+90=180
18y=180-90
18y=90
18y/18 =90/18
y=5
6 times 3 is 18.
So, he needs 18 strings.
Hope this helps!
