Step-by-step explanation:
P = 2l + 2w --> w = 1/2·P - l = 1/2·42 - 15 = 6 feet
Multiplication. When a variable is right next to a number and not as an exponent.
Answer: B
Step-by-step explanation:
<u>if 4w-1 ≥0</u> or w > 1/4 then
|4w-1|=4w-1
4w-1=5w+37 ==> w=-38 (exclude since not >1/4)
<u>else</u>
4w-1 < 0 or 4w <1 or w < 1/4
|4w-1|=-(4w-1)
-(4w-1)=5w+37
-4w+1=5w+37
9w=-36
w=-36/9
w=-4 ( which is < 1/4)
Sol={-4}
Answer B
Are you solving for x or y
y= 24x x= y/24
225/x = 100/75 = (225/×)(x) = (100/75)(x) = 225=1.333333333333333333333 = 225/1.33333333333333333333 = 168.75
so your answer is 168.75
