Answer:
x= 23 y=88
Step-by-step explanation:
3x+23= 4x
x=23
x and y are supplementary angles so they add up to 180 so then if x is 23
23 x 4= 92
so 180-92 is 88
therefore y is 88 and x is 23

Explain how you can compare the cost of two items that are different sizes.
Answers
Answer:
You can always compare to cost together but the big thing to look for is that you could be spending less for more on a product or the other way around, spending more for less product. you always want to go with the product that you are spending less money to get more product out of it.
Step-by-step explanation:
for example, say you are buying a pack of pencils, there is a pack of
10 pencils for 5 dollars
and
50 pencils for 10 dollarsthan
you would want to buy the second pack of pencils because you are getting each pencil for 50 cents rather than 2 dollars for each pencil in the first pack.
Answer:Sample Response: First find the unit price for each. Then compare the unit prices. The item that has the lesser unit cost is the better buy.

Graph x+3y=-6 using the x and y-intercepts.
Answers
Answer:
use points (0, -2) and (-6, 0)
Step-by-step explanation:
set up the equation in y-intercept form
x + 3y = -6
3y = -x - 6; divide by 3
y = [tex]\frac{-1}{3}[/tex] x - 2; you can the y-intercept is -2 or (0, -2)
Now to find where the graph cross the x-axis at y=0
0 = [tex]\frac{-1}{3}[/tex] x - 2; move the 2 to the other side
2 =[tex]\frac{-1}{3}[/tex] x ; multiply by -3
-6 = x; which is point (-6,0)

Hello!
[tex]\large\boxed{x = 4.5}[/tex]
To solve, we can use proportions:
Since the triangles are similar, their side lengths will be proportional to each other. We can set up a proportion to solve for the missing side length. Remember to use corresponding sides:
CA ~ FD and AB ~ DE
Therefore:
[tex]\frac{6}{16} = \frac{x}{12}[/tex]
Cross multiply to solve for x:
6 · 12 = 16 · x
72 = 16x
Divide both sides by 16:
72/ 16 = 16x / 16
x = 4.5

length: 1/2 width: 1/2 height: 3/4 what is the volume?
Answers
Answer:
3/16
Step-by-step explanation:
The formula for Volume is V = L * W * H
The given are L = 1/2, W = 1/2, H = 3/4
Substituting the values -
V = 1/2 * 1/2 * 3/4
= 3/16
= 3/16 divide by the Greatest Common Factor (GCF) of 3 and 16 to get the lowest term
= 3/16
Therefore, the volume of the box in 3/16.
Answer:
The volume is 3/16 cubic units.
Step-by-step explanation:
Given
Length l = 1/2
Width w = 1/2
Height h = 3/4
To determine
Volume = ?
The volume can be determined using the formula
Volume = l × w × h
substitute l = 1/2, w = 1/2, and h = 3/4
Volume = 1/2 × 1/2 × 3/4
Volume = 1/4 × 3/4
Volume = 3/16 cubic units
Therefore, the volume is 3/16 cubic units.
