Answer:
Angie=x
Susan = x+3
Rebecca = 3(x+3)
Total = 5x+12
If Angie has 4 then the total is 32
Step-by-step explanation:
Angie has x games
Susan has 3 more games than Angie has
Susan = x+3
Rebecca has 3 times more games than Susan
Rebecca = 3Susan
We know Susan has x+3 so replacing it in
Rebecca = 3 (x+3)
The total number of games is Angie + Susan + Rebecca
x + x+3 + 3(x+3)
Distributing the 3
x + x+3 + 3x+9
Combining like terms
5x+12
The total number of games is
5x+12
If Angie has 4 games, x=4
The total number of games is 5(x)+12
5*4+12
20+12
32
<h3>x = 1/2</h3>
Step-by-step explanation:
14x + 5 = 12
14x = 12 - 5
14x = 7
x = 7/14
x = 1/2

Answer:
Step-by-step explanation:
if solving for y
solve for y by simplifying both sides of equation, then isolating the variable.
y=-3w+10+W
if solving for W
W=3w-10+y
if solving for w
w=W/3 - y/3 + 10/3
Answer is 188
3x2 - 5xy + 5y2
Now put x = -6 and y = 2
3(-6)2 - 5(-6)(2) + 5(2)2
3(36) - 5(-12) + 5(4)
108 + 60 + 20
188
