-2(8p+2)-3(2-7p)-2(4+2p)=0
mutiply the first bracket by -2
(-2)(8p)= -16p
(-2)(+2)= -4
mutiply the second bracket by -3
(-3)(2)= -6
(-3)(-7p)= 21p
mutiply the third bracket by -2
(-2)(4)= -8
(-2)(+2p)= -4p
-16p-4-6+21p-8-4p= 0
-16p+21p-4p-4-6-8= 0 ( combine like terms)
5p-4p-4-6-8= 0
p-4-6-8= 0
p-10-8= 0
p-18= 0
move -18 to the other side to get p by itself
sign changes from -18 to +18
p-18+18= 0+18
p= 0+18
Answer: p= 18
Answer:
$35 for each sweater
Step-by-step explanation:
First subtract the skirt $160 - $20 = $140
Then Divide to find cost of each sweater $140/4 = 35
Answer: 35
16,000,000/2.25 =
7,111,111.11 milligrams of ozone PER DAY
How much per week?
7,111,111.11 * 7 =
49,777,777.78
Rounded
49,777,778 milligrams of ozone per week
Supplementary angles add up to 180°
Angle y is the large angle: y= 5x+6
180= x+y
180= (5x+6) + x
180=6x+6
174=6x
x=29
180= y+29
y=151°
Answer:
slope=4/5
y-intercept = -3
Step-by-step explanation:
first we need to rewrite the expression to
were b is the y-intercept and m the slope
so there we have it
