Answer:
see below
Step-by-step explanation:
a. -11r ≥ 220
Divide both sides by -11 to isolate r.
r ≥ -20
b.
-8 ≤ -7 + (x/10)
Add 7 to both sides.
-1 ≤ x/10
Multiply both sides by 10 to cancel out the denominator of x.
-10 ≤ x
c. -1 - 6(5q - 2) ≥ -139
Distribute the -6 across the parentheses.
-1 - 30q + 12 ≥ -139
Combine like terms on the left side.
-30q + 11 ≥ -139
Subtract 11 from both sides.
-30q ≥ -150
Divide both sides by -30 to isolate q.
q ≥ 5
Hope this helps!
Hello :
an equation is : y-5 = 0( x+7)...(the slope =0 '<span> horizontal line ' )</span> y=5
Answer:
128 m^2
Step-by-step explanation:
Perimeter = 48
(lenght is twice the width)
total Lenght(both sides) = 4b
total height(both sides) = 2b
--------------------------------------------------
4b +2b= 48
6b = 48
b = 48/6
b = 8
---------------------------------------------------
lenght = 16
height = 8
bxh = 8*16 = 128
Answer:
3/18
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of its side lengths.
P=2(L+W), we are told that L=3W and P=176 so
2(3W+W)=176
2(4W)=176
8W=176
W=22 ft, since L=3W
L=66 ft
So the yard is 22 feet wide and 66 feet long.
