Step-by-step explanation:
P.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Helvetica Neue'; color: #454545}
p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Helvetica Neue'; color: #454545; min-height: 14.0px}
Simplifying
3x + 7y = 28
Solving
3x + 7y = 28
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7y' to each side of the equation.
3x + 7y + -7y = 28 + -7y
Combine like terms: 7y + -7y = 0
3x + 0 = 28 + -7y
3x = 28 + -7y
Divide each side by '3'.
x = 9.333333333 + -2.333333333y
Simplifying
x = 9.333333333 + -2.333333333y
Answer:
s=650
Step-by-step explanation:
s=n/2(2a+(n-1)d)
s=20/2[2x4+(20-1)3]
s=20/2(2x4+19x3)
s=20/2(8+57)
s=20/2x65
s=10x65
s=650
4*1=4
4*2=8
4*3=12
4*4=16
4*5=20
4*6=24
4*7=28
4*8=32
4*9=36
4*10=40
4*11=44
4*12=48
