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
Hope this helps but I think the answer could be : 157+25m=50+60m

1.Three and Nine Hundredths 2. 3 9/100 3. 390%
Step-by-step explanation:
Answer:
2⁵× 2ˣ = 256
x= 3
(1/3)² (1/3)ˣ = 1/729
x= 4
Step-by-step explanation:
2⁵× 2ˣ = 256
x= 3
use Product Rule: xᵃxᵇ=xᵃ⁺ᵇ
convert both sides to the same base.
2⁵⁺ˣ = 2⁸
cancel the base of 2 on both sides.
5+x=8
subtract 5 from both sides.
x=8-5
simplify 8-5 3.
x=3
(1/2)² (1/3)ˣ = 1/729
x = 4
use division distributive property: (x/y)ᵃ=xᵃ/yᵃ
i hope this helped i didn't feel like typing the rest out though lol :(
