Answer:

Step-by-step explanation:
We can solve this system of equations using the elimination method.
Let's start by multiplying the first equation by 3:

Now, multiply the second equation by 5:

Since both equations have 15x, we can eliminate the x by subtracting the two equations.

Now, substitute 2 for y to solve for x:

Therefore the solution to this system of equations is:

Answer:
(x+4)(x-3) or A
Step-by-step explanation:
I'm going to assume that you meant to write x² and not x2
which means we have
x²+x-12
and we need to factor this
to do this we need two numbers that add up to 1 (b) but mulitply to -12 (a*c)
our two numbers are
4, -3
Which means the answer is
(x+4)(x-3)
(3/10) in = (7/8) mi
1 in = (7/8) mi ÷ (3/10)
= 7/8 * (10/3) = 70/24
1 in = (70/24) mi
It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.
Answer:
X is anywhere from 7 or any number bigger than 7.
(63x³+45x²)+(7x+5)
108x²+7x+5 is your answer
