ive answered in your other question u reposted ;)
Answer:
He can run 12 miles in 132 minutes.
Step-by-step explanation:
2/22=x/132
simplify 2/22 into 1/11
1/11=x/132
cross product
11*x=1*132
11x=132
x=12
Answer:
Step-by-step explPara que pueda ser una diferencia tiene que ser mayor al numero dado.
así que escogemos 15.
y el otro limite lo determinamos sumando 14+35= 49
anation:
First, we know the formula for area is:
Area = Length* Width
Therefore, 128 = (3x+7)(x+5)
We can use the F.O.I.L method to multiply
- First: (3x *x )= 3x²
-Outer: (3x*5) = 15x
-Inner: (7*x) = 7x
-Last: (7*5) = 35
Now we add the sum → 3x² + 15x + 7x + 35 → 3x² + 22x + 35
3x²+ 22x + 35 = 128
3x²+ 22x -93 = 0
Now you have to factor to solve for the x value.
<span>(<span><span>3x</span>+31</span>)</span><span>(<span>x−3</span><span>)
</span></span>x = 3 & x = -31/3
The negative value is eliminated because u can't have a negative length.
The length is 3x+7
L= 3(3) +7
L= 9+7
L= 16
