Mathematics
1 answer:
Ket [755]3 years ago
6 0

Answer:

Step-by-step explanation:

2=8/4 so the first fraction is 11/4

1=8/8 so the second fraction is 9/8

11/4=22/8

22/8*8/9=22/9

which statements are true regarding the equation? sorry it's blurry it's the best photo i could get of it all.
12345 [234]

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.

What is 4^2y-3^2=-5y+(-5+7)<br> Please explain step by step i need this asap :/
dybincka [34]

y = 11/21

To solve this first evaluate the power (then calculate the sum):

<u><em>4^{2}</em></u>y - <u><em>3^{2}</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 = \frac{11}{21}
