m - mile per driven
m = 40
Both of the cars would be the same.
The sentence "15% of 4x is 20 less than x"
translates to 0.15 • (4x) = x – 20
Solving that…
0.15(4x) = x - 20 multiplipy 0.15•4
0.6x = x - 20 subtract x from both sides
-0.4x = - 20 divide both sides by -0.4
x = 50
Answer:
C) 4x^2 -8x +4[/tex]
Step-by-step explanation:
(-2x+2)^2
we apply (a+b)^2 formula
a= -2x and b= 2
Replace 'a' with -2x and 'b' with 2
(-2x)^2 is 4x^2
option C is the answer
Answer:
Grace is the faster swimmer
Step-by-step explanation:
because Grace can do 25 m in .5 min, whereas Melanie can do 65 m in 1 minute, or 32.5 m in .5 min.
equation-
300 ÷ 5 = 60
325 ÷ 5 = 65
