Answer:

Correctomundo!

Step-by-step explanation:

For x-10 > 0:

1. Add 10 to both sides. x- 10 + 10 > 0 + 10

x > 10

For -5 + n < -6:

1. Simplify both sides of the inequality. n - 5 < -6

2. Add 5 to both sides. n - 5 + 5 < -6 + 5

n < -1

Help me solve this quickly please and show work!? I’m stuck

horrorfan [7]

I believe it is asking for x so I will be finding the value of x.

X = 4, work is shown below:

−2x=−3x+12−2x

Step 1: Simplify both sides of the equation.

−2x=−3x+12−2x

−2x=−3x+12+−2x

−2x=(−3x+−2x)+(12)(Combine Like Terms)

−2x=−5x+12

Step 2: Add 5x to both sides.

−2x+5x=−5x+12+5x

3x=12

Step 3: Divide both sides by 3.

3x/3 =1 2/3

x=4

Pleaseee help me this is gonna be due in a little and I need help bad it’s pretty algebra

Anarel [89]

Answer:

a.) .375 inches per day

b.) no

c.) 48 days

Step-by-step explanation:

If 8 days produces 3 inches of ice, I divided the 3 inches by the 8 days to see how much it grew per day. I got .375 inches per day.

Knowing how much it grew each day, I used .375 inches per day and multiplied it by 21 (3 weeks). So no, it only grew 7.875 inches over the 21 days.

You can double check it by dividing 10 inches / .375 inches per day and saw it would take over 26 days to reach 10 inches.

I took 1.5 feet and converted it to 18 inches. 18 inches divided by .375 inches per day equals 48 days.

I hope this helps you! :)
