Yes! :)
Step-by-step explanation:
-18 - 25z - 30 - 35z = -48 - 60z = 12(-4 - 5z)
-72 - 60z + 24 = -48 - 60z = 12(-4 - 5z)

Deena said that she received a 25 dollar discount but the equation says 9x + 25 = 28.
The Rewrite would be: 9x - 25 = 28.
How to make the situation fit the equation?: "I bought some shirts at the store for $9 each and received a $25 add on. My total bill was $88. How many shirts did I buy?"
An equation of the line that contains the origin and the point (1, 2) is
a) y = 2x
b) 2y = x
c) y = x - 1 d) y = 2x + 1 e) =x-1
d) y = 2x + 1 e) =x-1
e) =x-1
Answer:
a) y = 2x
Step-by-step explanation:
We can plug in the two points of (1, 2) and (0, 0) to find our answer. I am going to start by plugging in (0, 0). If it works, I will then plugin (1, 2)
a) y = 2x
0 = 2(0)
0 = 0 ✓
2 = (2)1
2 = 2 ✓
-> We got lucky, the first equation satisfies the question!
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Which of the following are equivalent to the ratio (2x-6):(6x-4)?
A. -2:1
B. X-3:3x-2
С. 3x x
D. (4x-12): (12x-8)
E. X-1 : x - 2
Answer:
B and D
Step-by-step explanation:
(2x-6):(6x-4)
you can divide everything by 2
2x÷2=x, -6÷2=-3
6x÷2=3x, -4÷2=-2
so it's B X-3:3x-2
(2x-6):(6x-4)
multiply everything by 2
2x × 2 = 2x, -6 × 2 = -12
6x × 2 = 12x, -4 × 2 = -8
so it's D (4x-12): (12x-8)
Answer:
x-3:3x-2 and (4x-12): (12x-8)
Step-by-step explanation:
Divide both sides by 2, then multiply both sides by 2

Answer:
m∡LMX = 150°
Step-by-step explanation:
m∡NML = 180 - (75+75) = 30°
m∡NML + m∡LMX = 180°
30 + 150 = 180
therefore, m∡LMX = 150°

What are the coordinates of B' if the origin is the center of dilation and the scale factor is 1/4?
Answer:
B' (1, 2 )
Step-by-step explanation:
Since the centre of dilatation is the origin then multiply the coordinates of B by the scale factor.
B (4, 8 ) → B' (4 × [tex]\frac{1}{4}[/tex] , 8 × [tex]\frac{1}{4}[/tex] ) → B' (1, 2 )
Answer:
1, 2
Step-by-step explanation:
When dealing with 1/4 scale factor, you just divide each point applicable by 4. Therefore:
(4, 8) > (1, 2)

Answer:
Step-by-step explanation:
∠AGB = ∠DGC {Vertically opposite angles}
∠AGB = 90°
∠AGE + ∠AGB + ∠BGF = 180 {Angles on straight line}
30 + 90 + x = 180
120 + x = 180
x = 180 - 120
x = 60°
Answer:
Solution,
Angle AGB=90°[Being vertically opposite angles]
Now we have,
30°+Angle AGB+x=180°
or,30°+90°+x=180°
or,x=180-30-90
Hence,x=60

Geometry
1. The size of angle x
2. The size of angle y
3. The size of angle z
Answer: x=40, y=70,
Step-by-step explanation:
To find angle x you first need to find O. You do this by subtract 180-40. Then you would get 140. Take this 140 and subtract it by 180. Your answer for x should be 40.
To find angle y you first need to know that x=40. Taking this you would subtract it by 180. It would leave you with 140. Taking 140 your going to dive it in half to get y. Your answer for y should be 70.
Sorry I'm not sure how to find z.

Jared is tiling his kitchen. He wants to buy tile at the cheapest price. The local hardware store sells tile for $5.27 per square foot of tile. The cost at the mega hardware store is shown in the graph. There is a proportional relationship between the number of tiles bought and the cost of the tiles. What is the cheapest price Jared will pay for 100 square feet of tile
The cheapest price for 100 square feet $527 is at the local hardware store.
What is the price for 100 square feet at the local hardware store?The total price is equivalent to the price of tile per foot multiplied by 100.

Write an inequality to represent the situation.
How far could Susan jump?
Susan can jump at most 104 in during the long jump
InequalityInequality is an expression that show the non equal comparison of two or more variables and numbers.
From the table, the average result for females = 8ft 4in = (8 * 12)in + 4in = 100 in
Since Susan could jump no farther than 4 inches more than the average distance for females, hence:

A graph shows both axes unnumbered. Points are scattered all over the graph.
Answer:
D) A graph shows both axes unnumbered. Points are scattered all over the graph.
Step-by-step explanation:
The value of "r" tells you how strong the correlation is between the independent and dependent variables. If its close to 0, then there will be hardly any correlation, so a good example of this is the 4th option where there's no pattern in the data set.
