Answer:
The new price is 66% off the original not 75% off
Step-by-step explanation:
Let x be the original price
First take 60 percent off
x - x*60% = new price
x- .60x = .40x
The new price is .40x
Then take 15 % off
(.40x) - (.40x)*15%
.40x - .40x*.15
.40x - .06x
.34x
100 -.34 =.66
The new price is 66% off the original not 75% off
Answer:
The y intercept is (0,-3)
Answer:
3.4h-2.7d-16
Step-by-step explanation:
Before we even start, we can already simplify some things
For example, in this equation it says +(-7.7d)
We can simplify this to 6h-7.7d-16+5d-2.6h
Now we have to get all of the common variables together
So the d’s and h’s have to be combined together in this equation
This makes a new equation of 3.4h-2.7d-16
That is our answer!
Answer:
They would be 132km apart
Step-by-step explanation:
In order to solve this we need to set up a proportion. To make that easier, let's first change the fractions into decimals.
2 1/2 = 2.5
5 1/2 = 5.5
Now we can put the scale in the right side fraction and the distance in the left.
2.5cm/60km = 5.5cm/xkm
Now cross multiply to solve
60 * 5.5 = 2.5 * x
330 = 2.5x
132 = x
Answer:
Choice D. a - b = 12 and a = 3b + 5
Step-by-step explanation:
so |a - b| = 12
a = 3b + 5
3b + 5 - b = 12
2b + 5 = 12
b = 7/2
what if b - a = 12
b - 3b - 5 = 12
-2b = 17
b < 0 no.
choice A. works so does choice D.)
