Answer:
I cant see good
Step-by-step explanation:
Answer:
x = -8
Step-by-step explanation:
x = 2y - 4 --- Equation 1
7x + 5y = -66 --- Equation 2
I will be using the substitution method to solve this.
Substitute x = 2y - 4 into Equation 2:
7x + 5y = -66
7(2y - 4) + 5y = -66
Evaluate.
14y - 28 + 5y = -66
Evaluate like terms.
19y - 28 = -66
Isolate 19y.
19y = -66 + 28
= -38
Find y.
y = -38 ÷ 19
y = -2 --- Equation 3
Substitute y = -2 into Equation 1:
x = 2y - 4
x = 2(-2) - 4
Evaluate.
x = -4 - 4
x = -8
Half of the distance from one side, through the middle, to the other side.
circumference: 3.14*radius*2
Answer: 2.35 miles
Check out the attached image below. A drawing often helps visualize the problem. In this case, all three locations are along the same vertical line. The distances 1.75 and 0.6 can be added up as those smaller segments form the entire distance we want (from park to library). So that's how I got 1.75+0.6 = 2.35
<h3>The two factors are 15 and y^3+6</h3>
Factors multiply to get a product. You can take this process in reverse.
As another example, the number 12 factors into 3*4, where 3 and 4 are the two factors. This idea applies to both numbers and variable expressions as well.
