stepan [7]

Answer:

B) -3                                 (Sorry if its overwhelming)

Explanation:

First, we have the given information of the weather over a <em>2</em> and <em>1/5</em> <em>span</em>

And we are asked to find the change per hour

We can first start by finding the <em>change</em> for 2 and 1/5 hours:

- Subtract the first amount by the second amount.

= (-6 3/5) - 0

= (-6 3/5) + 0

= -6 3/5

Now that we have the change for <em>2 and 1/5 hours</em> we must find the <em>change</em> per hour:

- Divide the given dividend by the given divisor

= -6 3/5 ÷ 2 1/5

= -3

Hence, the temperature <em>change per hour</em> over a 2 1/5 hour span is -3° per hour

0.50x-6=4 this is algebra 1 can you please help me
horsena [70]

0.50x-6=4

move -6 to the other side

sign changes from -6 to 6

0.50x-6+6= 4+6

0.50x= 10

divide by 0.50 for both sides

0.50/0.50x= 10/0.50

x= 20

Answer: x= 20

if 10 is less than a number is multiplied by 3, the result is equal to 2 times the number. What is the number?
olya-2409 [2.1K]
Hello!

We know that

(x - 10) * 3 = 2x

Distribute the 3

3x - 30 = 2x

Subtract 2x from both sides

x - 30 = 0

Add 30 to both sides

x = 30

The answer is 30

Hope this helps!
