What number is q in the problem -8-q-10q=-9q+6

Answers

Answer 1
Answer: For this question you can say:
-8 -11q = -9q +6 
so now you can add +9q on both sides and +8 on both sides of the equation:
-11q + 9q = 8 + 6 
-2q = 14 
q = 14/-2 
q = -7 :)))
I hope this is helpful
have a nice day
Answer 2
Answer: - 8 -11q = -9q + 6

-11q + 9q = 8 + 6

-2q = 14

q = -7

A 4-ounce cup of coffee costs $8.00. How much would a 3-ounce cup of cofee codt?

Answers

To solve this, we must first find out the cost-per-ounce of a cup of coffee. Assuming that the rates are flat, then we can just divide the 8-dollar-cost by the 4-ounce cup that it buys.

8 / 4 = 2

The cost-per-ounce of a cup of coffee is $2.
Now, we just have to multiply the cost-per-ounce by the amount of coffee we want to find out the cost of.

2 * 3 = 6

With all else constant, a 3-ounce cup of coffee would cost $6.

Arezo borrowed $2,500 from her grandfather. This graph shows the balance remaining on Arezo’s debt after she makes each payment. Using this graph, how much will she owe after 4 payments?

Answers

Answer:

She will owe $500 after 4 payments.

Step-by-step explanation:

With the help of graph

Number of payments (x)      Balance remaining(y)

         0                                         2500

         1                                          2000

         2                                         1500

Since it is linear function .

So, we will use two point slope form to find the equation for the given situation.

y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)   ----A

(x_1,y_1)=(0,2500)

(x_2,y_2)=(1,2000)

Substitute the values in A

y-2500=(2000-2500)/(1-0)(x-0)

y-2500=-500x

y=-500x+2500

Where x is the number of payments

y is the remaining payment

This equation represents the given situation.

So, to find the amount remaining after 4 payments .Substitute x =4

y=-500(4)+2500

y=-2000+2500

y=500

Hence she will owe $500 after 4 payments.

Answer:

She will owe $500

When combining like terms what is 7 + 8n - 10 put together?

Answers

Answer:

Step-by-step explanation:

7 + 8n - 10

= 7 - 10 + 8n

= -3 + 8n

hope this helps

plz mark it as brainliest!!!!!!!

Answer:

-3+8n

Step-by-step explanation:

7+8n-10

7 and 10 are both constants, so you'd add them together. However, since 10 is negative, it become 7+(-10), which is also just 7-10. 7-10=-3. Since 8n is the only number with a variable, it cannot be combined. Therefore, the expression becomes -3+8n.
