Answer:

Step-by-step explanation:

From the question the total angle here is 90° that means the angles are complementary.

Complementary angles are angles that add up to 90°

To find the value of x add the individual angles that's $\angle$ ZWY and $\angle$ XWY and equate it to

m $\angle$ XWZ that's 90°

So we have

$\angle$ ZWY + $\angle$ XWY = m $\angle$ XWZ

2x + 8 + 5x + 5 = 90

7x + 13 = 90

7x = 90 - 13

7x = 77

Divide both sides by 7

We have the final answer as

Hope this helps you

It is now twenty-five to four. What time will it be in one hour and forty-six minutes?

Dafna1 [17]

Answer:

5:21

Step-by-step explanation:

We know that currently (in the problem) it is 25 min before 4, or 3:35. When we add an hour to that (first part of the problem), we get 4:35. The way l like to continue from here is to take the second part (the 46 min) and just use part of it to round the hour off, and then add the other part to it.

From 4:35 to 5, we have 25 min

4.35 + 25 = 5

We subtract those 25 min from the 46 min, since we used them to round the hour off.

46 - 25 = 21

We have 21 min left, and now that the hour is rounded off, it's way easier to add minutes to it.

5 + .21 = 5.21.

So an hour and 46 min from 3:35 it will be 5:21. I hope this helps :)

How do you solve this problem: x/3-8=2. What do you get for x step by step please.

Kazeer [188]

Step 1: x/3-8=2
Step 2: x/-5=2
Step 3: -10/-5=2
Step 4: x=-10

Step 1: First, subtract 8 from 3. 3-8=-5.
Step 2: Replace 3-8 with -5.
Step 3: To find x, multiply -5 and 2. The answer is -10.
Step 4: Write out the final answer, which is x=-10

janet is comparing prices of bottled water. one bottle of water costs $1.92 and contains 12 ounces. another bottle of water cost

AnnyKZ [126]

Bottle 1 = $1.92 & 12 ounces

Bottle 2 = $2.40 & 16 ounces

Bottle 1

If 12 ounces costs $1.92, to determine the price of 1 ounce we divide $1.92 by 12.

$1.92 ÷ 12 = $0.16 per ounce for bottle 1.

Bottle 2

If 16 ounces costs $2.40, to determine the price of 1 ounce we divide $2.40 by 16.

$2.40 ÷ 16 = $0.15 per ounce for bottle 2.

Therefore we can determine that Bottle 2 is cheaper per ounce than Bottle 1.

Which value of x satisfies both - 9x + 4y = 8 and -3x-y= 4 given the same value of y?

lara31 [8.8K]

Answer:

$x=-\frac{8}{7}$

Step-by-step explanation:

We want to find the value of x that satisfies both

- 9x + 4y = 8

and

-3x-y= 4

given the same value of y.

This is the x-value of the point of intersection of the graph of the two lines.

We make y the subject of the bottom equation to get:

y=-3x-4

We substitute y=-3x-4 into the top equation to get:

-9x+4(-3x-4)=8

Expand to get:

-9x-12x-16=8

Group like terms

$-9x-12x=8+16$

-21x=24

$x=-\frac{24}{21}=-\frac{8}{7}$
