The character in our video multiplied the original value for black paint by 5 to get the new value for black paint. So, she also multiplied the original value for green paint by 5 to get the new value for green paint. There are multiplicative relationships, relationships related to multiplication, in a ratio table. To get from values for green and black in one ratio to values for green and black in another ratio, we can multiply both the initial values by the same number. For example, to get from the ratio 3:2 to the ratio 6:4, we multiply both the 3 and 2 by 2. And to get from the ratio 3:2 to the ratio 15:10, we multiply both the 3 and 2 by 5.

Sometimes, there are also relationships related to addition, called additive relationships, in a ratio table. To get from one value for green to another value for green, we can add 3. To get from one value for black to another value for black, we can add 2. When using the multiplicative relationship to find equivalent ratios, we can multiply both columns by the same number. But when using the additive relationship, we cannot add the same number to both columns.

solve for q.
5 = 2(q + 10) - -5

Answers

Answer:

q = -10.

Step-by-step explanation:

5 = 2(q + 10) - -5

5 = 2q + 20 + 5

5 - 20 - 5 = 2q

-20 = 2q

q = -20/= -10.

Answer:

Step-by-step explanation:

5=2(q+10)-5

5=2q+20-5

5=2q+15

5-15=2q

2q=-10

q= -10/2

q= -5

or

5=2(q+10)--5

5=2q + 20 + 5

5= 2q + 25

5-25=2q

2q= -20

2q= -20/2

q= -10

Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?

Answers

Answer:

42.66%

Step-by-step explanation:

subtract the amount of money from after and before: 1,635.30 - 1,422 = 213.3

divide the amount of money gained by the years: 213.3/5 = 42.66

The person above is correct because if you take the original amount Kim had and subtract that from the amount currently there you get 213.30 and you take that and divide that by 5 because of the 5 years you get
