The answer is C. Limpiemos
Answer:
Step-by-step explanation:
1)4.5m+4.7=20m+47
4.5m-20m=47-4.7
-15.5m=42.2
m=-2.72
2)14+21w=7(2+3w)
41+21w=14+21w
21w-21w=14-41
3)49r+35=7(7r+35)
49r+35=49r+245
49r-49r=245-35
4)9(8h-3)=72h-27
72h-27=72h-27
72h-72h=-27+27
5)5.2+5.3t=10+15t
5.3t-15t=10-5.2
-9.7t=4.8
t=4.8/-9.7
t=0.49
6)6f+3.111=18f-33
6f-18f=-33-3.111
-12f=-36.111
f=-36.111/-12
f=3.01
11x + 7x = 180
When solved, x = 10.
Plug in the x to find the angle measurements
Answer:
-7
Step-by-step explanation:
First, we know that we are solving for x so what we need to do is to find out what times -5=35.
We know that
-5x7=-35
So we know our answer cant be positive 7, which means we need the opposite of 7 which is -7.
And:
-5x-7=35
This makes the equation true:
Hence, the correct answer is -7
The length and the width of the rug having an area of 40 square feet will be 5 feet and 8 feet respectively.
<h3>what is area?</h3>
Area is defined as the space covered by any object in the two dimensional plane. Here it is given that the area of the rug should be 40 square feet and the length of the rug is 3 less then its width.
So to find out the length and the width we will form an equation.
Let the width is = x feet
So the length will be = x-3 feet
Now the area will be
By solving the quadratic equation
Here the value of x will be positive because length cant be negative.
So the width of the rug will be x=8 feet
Length of the rug will be x-3= 8-3=5 feet
Hence the length and the width of the rug having an area of 40 square feet will be 5 feet and 8 feet respectively.
