Answer:
You will do the Distributive Property first.
Step-by-step explanation:
You will do the Distributive Property first.
4(x - 3) = 9 <u>distribute the 4 into the x and -3.</u>
4x - 12 = 9 <u>add -12 to both sides.</u>
4x = 21 <u>divide 4 on both sides.</u>
x = 5.25 is your answer.
Answer:
first stage=420km
second stage=360Km
Step-by-step explanation:
Hi!
To solve the problem follow the steps below
1. We will call X to the first stage and Y to the second stage.
2. Raise the equations taking into account the following
the sum of both stages is 780km
X+Y=780km
the first stage has 60km more than the second
Y+60=X
X-Y=60
3. Add the equations found above
X + Y =780
X - Y =60
------------------------
2X=840
Solving for X=840/2=420Km
use one of the equations obtained in step 2, to get the value of Y
Y+60=X
X-60=Y
420-60=Y
Y=360km
Answer:
n = -5
Step-by-step explanation:
-6(-5n+3)+2=-166
distribute the -6
- 6 * -5n = 30n
-6 * 3 = - 18
30n - 18 + 2 = -166
combine like terms
30n - 16 = -166
add 16 to both sides
30n = -150
divide both sides by 30
30n/30=n
-150/30=-5
we're left with n = -5
We know that
<span>An asphalt driveway </span>has the shape of a rectangle
so
area of rectangle=long*wide
area=21*10.5-----> 220.5 ft²
the answer is
220.5 ft²
