I believe its -5 1/4

Step-by-step explanation:

Cymath is a good help.

Answer:all real numbers are solutions

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Subtract 4f from both sides.

Step 3: Add 13 to both sides.

0=0

Answer:

f(.4)=3.7

Step-by-step explanation:

Answer: b = 90

Step-by-step explanation:

Full triangle is 180

5 + 4 = 9 + 1 (the smallest angle)

180 ÷ 10 = 18

First and smallest angle is 18

p= 18

Second angle is 72

18 × 4 = 72

Thrid angle is 90

18 × 5 = 90

b = 90

18 + 72 = 90 + 90 = 180

Answer:H

Step-by-step explanation:

Because 0.25 x 9 will give you 2.25. Then add that to the original number; $3.50 + $2.25 = $5.75. Hope this helps :)  

Answer:

5. No,  Triangle J K L is a Reflection, not a translation

6. Its 11 to the right, and 2 up

Answer:

5. No, it is a translation across the Y-Axis

6. The translation is 11 units right, and 2 units up.

Answer:

1. 6/15, or 2/5.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

Answer:

Proportional

Step-by-step explanation:

It is proportional because the relationship between the quantities are constant. If we look at the first two points, 10-5 / 2-1. = 5       If we look at other points, they will all equal 5. This means it is constant and therefore proportional.

Answer:

30+0.05t < 60

Step-by-step explanation:

0.05 is the rate, 30 is the initial, 60 is the maximum (not cincluding it though, since it says under 60)

Answer:

x/3.5h = -$1.4

So, x = -$1.4 * 3.5h

= -$4.9

Step-by-step explanation:

Since your losing $1.4 every hour, the 1.4 is supposed to negative.

Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours

and get  -$4.9.

Answer:

5 + n - 5  = 10 - 10

Step-by-step explanation:

if you do 5-5 that would equal zero, and if you do 10-10 it would equal 0 also, so all you would be left with is 0 + n= 0 and that is not equal to 5 + n = 10

Answer:

5 + n - 5  = 10 - 10
