Answer:
x = -2
Step-by-step explanation:
7(2 - x) = 28
Distribute
14 -7x = 28
Subtract 14 from each side
14-7x-14 = 28-14
-7x = 14
Divide each side by -7
-7x/-7 = 14/-7
x = -2
Answer:
2/3
Step-by-step explanation:
total marbles is (8 black+ 16 white + 14 red +10 green) = 48
no white cmarbles ( 8+14+10) = 32
32/ 48 = 2/3
- 32/16= 2
- 48/16 =3
The answer is 32 b/c when you substitute the x in for 3 you get 4^3 which is 64. 64*1/2 is 32
Answer:
equation of a line is given by
y -y1 / x - X1 ==> y2 - y1 / X2 - X1
where yi = 5, y2 = -2
and x1 = -2, x2 = 5
from the equation above
y -y1 / x - X1 ==> y2 - y1 / X2 - X1
y -5 / X -(-2) ==> -2-5 / 5 - (-2)
y -5 / X + 2 ===> -7 /7
y - 5/ X + 2 ===> -1
cross multiply
y -5 ==> -1(X + 2)
y -5 ==> -x -2
collect like terms
y + x -3 = 0
or
y + X ===> +3
