Answer:

3x+y=24

Step-by-step explanation:

Let the loaves sold be x and rolls sold be  y.

Given:

Cost for 1 loaf of bread = $3

∴ Cost of x loaves of bread = 3x

Cost of 1 roll of bread = $1

∴ Cost of y rolls = 1y

Total cost of the baked goods = $24

Therefore, as per question,

3x+1y=24\\3x+y=24

Now, the graph is shown below.

The vertical axis represent the rolls sold and the horizontal axis represent the loaves sold.

Draw a horizontal line from 12 mark on the vertical axis to the given line to meet at point A. Now, from point A, draw a vertical line to meet the horizontal axis at point B. Point B is the number of loaves sold.

From the graph, loaves sold are 4 when rolls sold are 12.

When 8 is subtracted from Ollie’s age, the result is the same as subtracting 16 from 3 times his age.
Scilla [17]
X - Ollie's age

8 is subtracted from Ollie's age = x-8
the result is the same as
subtracting 16 from 3 times his age = 3x-16

x-8=3x-16 \\
x-3x=-16+8 \\
-2x=-8 \\
x=4

Ollie is 4 years old.

Solve 2(4 x + 3) < 5 x + 21. { x | x < 9} { x | x > -5} { x | x > -9} { x | x < 5}
Nesterboy [21]

Answer:

x <5

Step-by-step explanation:

2(4 x + 3) < 5 x + 21

Distribute

8x +6 < 5x +21

Subtract 5x from each side

8x -5x +6 < 5x-5x+21

3x +6 < 21

Subtract 6 from each side

3x+6-6 <21-6

3x <15

Divide each side by 3

3x/3 <15/3

x <5

Find the sum (the total measure) of the interior angles of an Octagon. Show all of your work
tatiyna
One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon  = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees

so total measure of all angles in octagon = 8 * 135 =  1080 degrees

1. Given ΔQRS (is congruent to) ΔTUV, QS = 3v + 2 and TV = 7v - 6, find the length of QS and TV. Provide a detailed response bel
Morgarella [4.7K]
Because ΔQRS is congruent to <span>ΔTUV, the the segments GS and TV are also congruent due to the letter order (Q and T are first and S and V are 3rd.) Since they are congruent QS=TV. So 3v + 2 = 7v - 6
</span><span>
</span><span>Work: 
</span>3v + 2 = 7v - 6
      +6          +6
3v + 8=7v
-3v       -3v
<u>8</u> = <span><u>4v</u>
</span>4      4
2 = v

3(2) + 2 = GS
6+2 = GS
8 = GS

7(2) - 6 = TV
14-6=TV
8 = TV

Final Answer: 8=QS and 8=TV
