Answer:
7
Step-by-step explanation:
hi , you can see here we have a rectangle without a triangle :
area rectangle - area triangle = area of the shape
Area of the triangle= L x l
=4 x 2
=8
Area of the triangle = ![\frac{b X h}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%20X%20h%7D%7B2%7D)
=![\frac{2 X 1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%20X%201%7D%7B2%7D)
=1
So we do : 8 - 1 = 7
I hope it is gonna be helpful,
have a nice day.
To solve for X, you first add the integers together and the X variables together. Then you subtract 3 from each side, followed by dividing by 3 on each side. Here is the work to show our math:
X + X + 1 + X + 2 = 154
3X + 3 = 154
3X + 3 - 3 = 154 - 3
3X = 151
3X/3 = 151/3
X = 50 1/3
Since 50 1/3 is not an integer, there is no true answer to this problem.

Answer:
She typed 32 words in her letter
Step-by-step explanation:
Assume that the letter has x words
∵ She typed x words in her letter
∵ She misspelled 8 words
∵ She misspelled 25% of the words she typed
∴ She misspelled 25% of x
→ That means 8 is equivalent to 25% of x
∴ 25% of x = 8
∴ 25% × x = 8
→ Change 25% to decimal by divide it by 100
∵ 25% = 25 ÷ 100 = 0.25
∴ 0.25 × x = 8
∴ 0.25x = 8
→ Divide both sides by 0.25
∵
= ![\frac{8}{0.25}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B0.25%7D)
∴ x = 32
∵ x represents the number of words that she typed in the letter
∴ She typed 32 words in her letter
Answer:
0.6 hours
Step-by-step explanation:
Let's say the swimming pool is 12,000 gallons.
The flow rate of the cold water pipe is:
12000 gal / 4 hr = 3000 gal/hr
The flow rate of the hot water pipe is:
12000 gal / 6 hr = 2000 gal/hr
If the cold water pipe is turned on for three hours, the volume of water is:
3000 gal/hr × 3 hr = 9000 gal
That leaves 3000 gallons. The time to fill the rest of the pool with both the cold and hot water pipes is:
3000 gal / (3000 gal/hr + 2000 gal/hr) = 0.6 hr
It takes 0.6 hours (36 minutes).
Answer:
Step-by-step explanation:
⇒o 2/-3 Doesn't matter where the minus is as long as there an odd numbere of them.
o -3/-2
o -2/-3
⇒o - 2/3 This is given. Is it really listed.
o -3/2
o -2/2
There really are only 2 of them. 3/2 in any form is not equal to 2/3.
-2/2 = - 1 not -2/3
-2/-3 There are an even number of - signs. The answer is 2/3
