Answer:

x = 29

(x + 3)° = 32°

(x - 1)° = 28°

(x + 1)° = 30°

Step-by-step explanation:

(x + 3)° + (x - 1)° + (x + 1)° = 90°

-> (x + x + x +3 -1 + 1)° = 90°

-> (3x + 3)° = 90°

-> 3x + 3= 90

-> 3x = 90 - 3

-> 3x = 87

-> x = 87/3

-> x = 29

-> (x + 3)° = (29 + 3)° = 32°

-> (x - 1)° = (29 - 1)° = 28°

-> (x + 1)° = (29 + 1)° = 30°

Answer:

x=29

Step-by-step explanation:

The square notation indicates 90 degrees.

90=(x+3)+(x-1)+(x+1)

90=3x+3

87=3x

x=29

Write your answer as a fraction in simplest form subtract 5/8-3/5

svetoff [14.1K]

first you need to find the least common denominator which in this case it is 40. since 5 and 8 both go into 40.

5/8 = 25/40

3/5 = 24/40

25/40 - 24/40 =1/40

does this make sense to you?

A shoes store sells three categories of shoes, Athletics, Boots and Dress shoes. The categories are stocked in the ratio of 5 to

Elena-2011 [213]

Answer:

350 pairs

Step-by-step explanation:

If the ratio of Athletics, Boots, and Dress shoes is 5 to 2 to 3, it means that for every 2 pairs of Boots they have 5 pairs of Athletics shoes and 3 pairs of dress shoes.

So, if they have 70 pairs of boots, we can calculate the number of Athletics as:

$\frac{5*70}{2} =175$

And if they have 70 pairs of boots, the number of dress shoes are:

$\frac{3*70}{2}=105$

Finally, they have 70 pairs of boots, 175 pairs of athletics, and 105 pairs of dress shoes. It means that they have 350 pairs in total.

70 + 175 + 105 = 350

At 6:00 A.M. the temperature was 33°F. By noon the temperature had increased by 10°F and by 3:00 P.M. it had increased another 1

chubhunter [2.5K]

So let's see here...

6:00 A.M. temperature is 33°F.

12:00 P.M temperature increased by 10°F making it 43°F.

3:00 P.M. temperature increased by another 12°F making it 55°F.

At 10:00 P.M it would decrease by 15°F making it 40°F.

The temperature would need to fall (or decrease) by 7°F to reach the original temperature of 33°F

Hope this helped!
