4. 3x-27 = 90
3x = 63
x = 21
5. 2x+30 = 60
2x = 30
x = 15
F you divide 249 by 32, you get 7.78125.
Y = mx + b
where m is the slope and b is the y-intercept.
1. 2x + 3y = 12
3y = -2x + 12
y = -2x + 4
y-intercept is 4
2. x - 4y = 20
-4y = -x + 20
y = -x - 5
y-intercept is 5
3. y = 2x - 9
this one is easy because it's already in standard form
y-intercept is -9
Answer:
x = 1/15
Step-by-step explanation:
-5(3x-1+3x) = 3
add like terms:
-5(6x-1) =3
distribute -5 throughout the Parentheses:
-30x+5= 3
move the constant to the right side and change it's sign:
-30x=3-5
calculate:
-30x= -2
Divide both sides by -30:
x = 1/15
You multiple lengthxwidthxheight and with those numbers it is 125
