Answer:
X= -8
Step-by-step explanation:
First you distribute the 5 to the parenthesis to get 5x-30+4=7x-10. Then subtract 14 on both sides to get 5x-16=7x. Next, subtract 5x from both sides to get -16=2x. Now you divide by 2 on both sides to get -8=x.
Answer: x = - 8
Step-by-step explanation:
The first step in applying the distributive property:
5 (x - 6) + 4 = 7x - 10
5x - 30 + 4 = 7x - 10
The second step is to combine like terms by subtracting 10 from -30, and subtracting 4 from - 20:
5x - 30 + 4 = 7x - 10
5x - 16 = 7x
The third step is to subtract 5x from 7x:
5x - 16 = 7x
- 16 = 2x
The last step is to divide each side by 2 to isolate the variable, or find x:
- 16/2 = 2x/2
- 8 = x
or x = - 8

By talking to the sales clerk at the hardware store, you find out that the burglar has two hideouts — the lake house and the cabin. Given the coordinate plane below, calculate the distances between the store and each hideout. Which hideout is closest to the store?
Find the x-intercept and the y-intercept of the line below. Click on "None" if applicable.
Answer:
x- intercept is -2
y-intercept is 3
Step-by-step explanation:
x - intercept is x = -2
y intercept is y = 3
This is dealing with x and y intercepts of straight line graphs.
In straight line graphs, the y - intercept is simply the point where the line touches the y - axis while the x-intercept is the point where the line touches the x-axis.
From the graph given, the line touches the y-axis at y = 3 while it touches the x-axis at x = - 2
Thus;
x - intercept is x = -2
y intercept is y = 3

3 lines are shown. A line with points T, R, W intersects a line with points S, R, W at point R. Another line extends from point R to point U between angle T, R, V. Angle V R W is (3 x) degrees and angle T R S is (2 x + 18) degrees.
What is m∠SRW?

Answer:
m∠SRW = [tex]126^{o}[/tex]
Step-by-step explanation:
Given: <VRW = 3x
<TRS = (2x + 18)
What is m∠SRW?
<TRS = <VRW (vertically opposite angles)
2x + 18 = 3x
18 = 3x - 2x
x = 18
<VRW = 3x = 3 x 18 = [tex]54^{o}[/tex]
<TRS = (2x + 18) = 92 x 18 + 18)
= [tex]54^{o}[/tex]
Also,
<TRV = <SRW (vertically opposite angles)
So that,
<TRU + <URV = <SRW
But,
<TRV + <SRW + <TRS + <VRW = [tex]360^{o}[/tex]
<TRV + <SRW + [tex]54^{o}[/tex] + [tex]54^{o}[/tex] = [tex]360^{o}[/tex]
<TRV + <SRW + [tex]108^{o}[/tex] = [tex]360^{o}[/tex]
<TRV + <SRW = [tex]360^{o}[/tex] - [tex]108^{o}[/tex]
<TRV + <SRW = [tex]252^{o}[/tex]
2 <SRW = [tex]252^{o}[/tex] (∵ <TRV = <SRW)
<SRW = [tex]\frac{252}{2}[/tex]
= [tex]126^{o}[/tex]
Therefore,
m<SRW = [tex]126^{o}[/tex]

Ray and 3 friends played with a remote-control car for a total of 105 minutes. They each played with the car for the same amount of time. Which statement about the amount of time Ray and his friends spent playing with the car is true?
Answer:
Time Taken by each = 26 min 15 sec
Step-by-step explanation:
Given:
Total time play = 105 min
Total number of friends = 1+3 = 4
Each play equal
Find:
Time Taken by each
Computation:
Time Taken by each = Total time play / Total number of friends
Time Taken by each = 105 / 4
Time Taken by each = 26 min 15 sec

Q1: What signals you that factoring by grouping is the best method to use when factoring a
problem? How would you know if it is factorable or prime?
Answer:
You know a number is not factorable or prime if nothing multiplies to it.
Step-by-step explanation:
For example there are no numbers that multiple to 7, same with 19. No 2 numbers will ever be able to = to 7 or 19 for example.
Hope this helps!!!
Answer:
prime numbers would be 2,4,6,8,10,12, and etc.....
Step-by-step explanation:
factorable means say we have the number 32 it factors down to 16 then 16 factors down into 8 then 8 goes down into 4 then 4 goes dow into 2

(v) −5y
Answer:
-5y
Step-by-step explanation:
We are to simplify the expression
5x - 5(y+x)
Open the bracket by applying the distributive law;
5x-(5(y)+5(x))
5x - (5y+5x)
5x - 5y - 5x
Collect like terms to have:
5x - 5x - 5y
0-5y
= -5y
Hence the simplified form is -5y

its the same thing
Answer:
see explanation
Step-by-step explanation:
• The diagonals bisect each other at right angles, then
∠ 2 = ∠ 3 = 90°
∠ 1 = 180° - (90 + 52)° ← angle sum of a triangle
∠ 1 = 180° - 142° = 38°
• Diagonals bisect the endpoints, then
angle at vertex with ∠ 1 = 76° and
angle at vertex with ∠ 4 = 76°, thus
∠ 1 = ∠ 4 = 38°
In conclusion
∠ 1 = 38°, ∠ 2 = 90°, ∠ 3 = 90°, ∠ 4 = 38°

Two people decided to race. One of the cars is 10 meters north of the start line 5 seconds into the race. After 15 seconds, the car is 25 meters north of the start line. Calculate the average velocity of the car.
Answer:
The average velocity of the car is 1.5 m/s
Step-by-step explanation:
The given parameters are;
The displacement of one of the cars north of the start after 5 seconds = 10 meters
The displacement of the car north of the start after 15 seconds = 25 meters
The average velocity of the cars [tex]\overline v[/tex] is given as follows;
[tex]\overline v = \dfrac{\Delta x}{\Delta t}[/tex]
Where;
Δx = The change in the displacement of the car = 25 m - 10 m = 15 m
Δt = The corresponding amount of the change in time 15 s - 5 s = 10 s
By substituting the known values of Δx and Δt in the equation for the average velocity of the car, [tex]\overline v[/tex], we have;
[tex]\overline v = \dfrac{15 \ m}{10 \ s} = 1.5 \ m/s[/tex]
∴ The average velocity of the car, [tex]\overline v[/tex] = 1.5 m/s
