Answer:
Value of n is 52
Step-by-step explanation:
So you have equation: 6.2n – 3.7n = 85 + 45
First, you need to collect the like terms and add the numbers on the other side: 2.5n=130
Now, you need to divide both sides of equation by 2.5. And you will get the answer. n=52
Answer:
1.8 miles
Step-by-step explanation:
For this case we can model the problem as a rectangle triangle.
We know:
Length of the sides of the triangle
We want to know:
Length of the hypotenuse
Using the Pythagorean theorem we have:

Then, the distance that he would have saved if he travels directly is:

Answer:
he would have saved:
1.8 miles
Answer:
looks like C is best guess
13. (a-b)^2=a^2-2ab+b^2
B is the answer
14. B is the answer
( x+9)(x-3)= x^2+6x-27
15. B is the answer
(x+6)(x-5)=x^2+x-30
16. D is the answer
(x-6y)(x-4y)=x^2-10xy+24y^2
17. C is the answer
(2x+5)(3x-4)=6x^2+7x-20
18. B is the answer
(5x+7)(x-2)=5x^2-3x-14
