Answer:
150 + 1.5d
Step-by-step explanation:
increase 120 by d%
d% = d/100
So, increasing 120 by d % means
120 + (d/100 * 120)
= 120 + 1.2d
Then increase this by 25%
= (120 + 1.2d) + 25/100(120 + 1.2d)
= 120 + 1.2d + (120+1.2d)/4
= 120 + 1.2d + 30 + 0.3d
= 120 + 30 + 1.2d + 0.3d
= 150 + 1.5d
Answer:
Number 1 is 10 and number 2 is 7
14/2 = 7
7 + 3 = 10
7/8(x-1/2)=-49/80
70/80(x-40/80)=-49/80 make all common denominator
x-40/80=-56/80 divide -49/80 by 70/80 to isolate parentheses
x=16/80 or 1/5 add 40/80 to isolate x
I'm not sure if my answer right because I was rushing but if you follow what I wrote next to the lines you should get the right answer
I think there are 7 nickels, because 7 dimes equals 70 cents, plus 7 × 3 = 21 , 21 × 5 = 105
70 + 105 = 175
The question asks, "how many kilometers of road did they build each day?"
This means: kilometers per day
kilometers/days
(635 kilometers)/(3 days)
635/3 kilometers/day
211 2/3 kilometers/day
