W=148
V=180-148=32
V=32
T=148
S=148
Yes, it is correct
J + t = 30
j = 2t - 3
sub eq 2 into eq 1
2t - 3 + t = 30...combine like terms
3t - 3 = 30...add 3 to both sides
3t = 30 + 3
3t = 33...divide both sides by 3
t = 33/3
t = 11 <=== Tritt is 11
j = 2t - 3
j = 2(11) - 3
j = 22 - 3
j = 19 <== Jan is 19
Answer:
Step-by-step explanation:
Answer:
1) Adding
2) x = 1.5 y = 8
Step-by-step explanation:
1. Which would be a more helpful for solving the system: adding the two equations or subtracting one from the other?
Adding.
Would eliminate the y variable
2.solve the system without graphing, show your reasoning
After adding the equations
8x = 12
Divide both sides by 12
x = 1.5
Substitute into the first equation
2(1.5) + (1/2)y = 7
3 + (1/2)y = 7
(1/2)y = 4
y = 8
1. 18x+16 in
To find the perimeter of a rectangle you have to add all the side together. Two sides are 5x+2 in and two sides are 4x+6 in. 5x+2+5x+2+4x+6+4x+6=18x+16
Sorry I don't know how to do the others.
