Given that 2 large puzzle costs $16 then
2l=16
or
l=8
That means cost of 1 large puzzle = $8
Given that 3 small puzzle costs $15 then
3s=15
or
s=5
That means cost of 1 small puzzle = $5
Now we will use this information to find the correct choice.
---
First choice is <u>wrong </u>as coefficient 8 is with 8l so that gives cost of 1 large not small puzzle.
---
Second choice is <u>correct </u>as coefficient 8 is with 8l so that gives cost of 1 large puzzle.
---
Third choice is <u>correct </u>as coefficient 5 is with 5s so that gives cost of 1 small puzzle.
---
Fourth choice is <u>Wrong </u>as coefficient 5 is with 5s so that gives cost of 1 small not large puzzle.
---
Fifth choice is <u>wrong </u>as constant 128 gives total cost of not the total number of puzzles.
Answer:
b = 1/2m
Step-by-step explanation:
Let:
- b = beth's age
- m = meg's age
The prompt tells us that Beth is half as old as Meg. Therefore, mathematically, b = 1/2m.
y = 11/21
To solve this first evaluate the power (then calculate the sum):
<u><em>
</em></u>y - <u><em>
</em></u> = 5y +<u><em> (-5 + 7)</em></u>
16y - 9 = -5y + 2
Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):
16y <u><em>- 9 </em></u>= <u><em>-5y</em></u> + 2
16y + 5y = 2 + 9
Next Collect the like terms and calculate the sum:
<u><em>16y + 5y</em></u> = <u><em>2 + 9</em></u>
21y = 11
Lastly divide both sides of the equation by 21:
<u><em>21y = 11</em></u>
y = 
7/11
you do rise over run, which is y2-y1/x2-x1
Answer: your answer is negative $88.31
Step-by-step explanation:
$15,440 minus $42,50 minus $51,50 minus $9,75= negative $88.31
