PLEASE HELP IM TIMES AND EXPLAIN STEP BY STEP , so using substitution method solve the system of equations , y = 2x + 8 and y = 4x - 2 , whoever answers step by step gets brainliest
Answer:
y= 2x + 8 , y = 4x - 2
2x + 8 = 4x - 2
8 = 2x - 2
10 = 2x
5 = x
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
y = 2x + 8
substitute the y in the other expression with this expression (you can do it vise versa too but i chose this because it was first)
2x + 8 = 4x - 2
goal is to isolate the variable
add 2 to both sides (this cancels out the -2 on the right side)
2x + 8 + 2 = 4x - 2 + 2
2x + 10 = 4x + 0
2x + 10 = 4x
subtract -2x from both sides (cancels out the 2x on the left side)
2x - 2x + 10 = 4x - 2x
0x + 10 = 2x
10 = 2x
divide both sides by 2 (cancels out the 2 on the right side)
10 ÷ 2 = 2x ÷ 2
5 = 1x
5 = x
variable is isolated and tells us that x = 5

Answer:
∠8 * 4 = ∠7 ----------------(1)
∠8 + ∠7 = 180 ------------(2)
Taking the value of ∠7 from (1) and using it in (2):
∠7 = 4 * ∠8
∠8 + ∠7 = 180
∠8 + (4 * ∠8) = 180
∠8 + 4∠8 = 180
5∠8 = 180
∠8 = 36° ---------------(3)
Using the value of ∠8 from (3) in (2):
∠8 + ∠7 = 180
36 + ∠7 = 180
∠7 = 144° and ∠8 = 36°

A pet store has 10 cats, 9 dogs, and 8 turtles. If Mario randomly selects a pet to take home, determine his Theoretical Probability of selecting a cat or a dog.
Answer:
Let's see what to do buddy...
Step-by-step explanation:
_________________________________
STEP (1)
We have to know how many pets does the pet store have.
Look : 10 + 9 + 8 = 27
So the pet store completely have 27 pets.
_________________________________
STEP (2)
Mario randomly selects a pet :
[tex] \frac{10}{27} \\ [/tex]
Is the Probability of selecting a cat.
##############################
[tex] \frac{9}{27} \\ [/tex]
Is the Probability of selecting a dog.
_________________________________
STEP (3)
(( or )) in mathematics means plus (( + )) .
So the Probability of selecting a cat or a dog means :
[tex] \frac{10}{27} + \frac{9}{27} = \frac{19}{27} \\ [/tex]
_________________________________
STEP (4)
There's no STEP 4.
And we're done.
Thanks for watching buddy good luck.

In a triangle, the measure of the first angle is twice the measure of the second angle. The measure of the third angle is 88° more than the measure of the second angle
Use the fact that the sum of the measures of the three angles of a triangle is 180° to find the measure of each angle
The measure of the first angle is º
The measure of the second angle is
The measure of the third angle is nº
Answer:
Step-by-step explanation:
The measure of the second angle = n
The measure of the first angle = 2*n
The measure of the third angle = n + 88
==================
n + 2n + n + 88 = 180
4n + 88 = 180
4n = 180 - 88
4n = 92
n = 92/4
n = 23
============
second angle = 23
First angle = 2*23= 46
Third angle = 23 +88 = 111
The total is 180

Speedy Swift is a package delivery service that serves the greater Atlanta, Georgia, metropolitan area. To maintain customer loyalty, one of Speedy Swift's performance objectives is on-time delivery. To monitor its performance, each delivery is measured on the following scale: early (package delivered before the promised time), on-time (package delivered within 15 minutes of the promised time), late (package delivered more than 15 minutes past the promised time), or lost (package never delivered). Speedy Swift's objective is to deliver 99% of all packages either early or on-time. Speedy collected the following data for last month's performance:

Reuben has been saving $6 each week. Today he spent $90 of the savings, and he now has $48 left. For how many weeks has he been
saving?
(a) Write an equation that could be used to answer the question above.
First, choose the appropriate form. Then, fill in the blanks with the
Answer:
23 weeks
Step-by-step (x = weeks)
90 + 48 = 138
divide 138 by 6 to find out how many weeks he'd been saving up .
that gives you 23 but to turn it into an equation
6x - 90 = 48
+ 90 +90
6x = 138

6 6
x = 23 again x meaning weeks

Find the coordinate of b if ab=8 and the coordinate of a is -2
Answer:
-2 times 4
Step-by-step explanation:
The coordinate of b will be equal to b = - 4.
It is given that ab = 8 and coordinate of a = -2.
We have to find out the coordinate of b.
What will be the value, if 8 is divided by 2 ?
The value will be equal to 8 ÷ 2 = 4.
As per the question,
ab = 8
Also , value of coordinate a is given as a = -2.
Putting the value of a in above equation , we get ;
(-2) × b = 8
b = 8 ÷ (- 2)
b = - 4
Thus, the value of coordinate b will be equal to -4.
