2.3r-y+6=21
Find r when y=7
Find y when r=4.23

Answers

Step-by-step explanation:

2.3r - 7 + 6 = 21

2.3r - 1 = 21

2.3r = 22

r = 22/2.3

r = 9.6

2.3(4.23) - y + 6 = 21

9.73 - y + 6 = 21

15.73 - y = 21

-y = 5.27

The cost of Marianne's old bracelet is two-thirds
The cost of her new bracelet. The cost of her old
bracelet is $18. Need help what Is this solution

Answers

Answer:

the answer is $12

Step-by-step explanation:

to get the answer you would multiply 18 by 2/3 or you can divide by 3 then multiply what you get from dividing by 3 by 2.

version 1: 18(2/3) = ?

version 2: 18/3=?

6 you want to multiply by to because that is 1/3 of the original price

6(2) = 12

Either way you get the same answer. Hopes this helps

5(r + 3) = 3r + 35.
What is the answer and please show how you got it

Answers

Answer:

r =10

Step-by-step explanation:

5(r + 3) = 3r + 35.

Distribute

5r+15 = 3r+35

Subtract 3r from each side

5r+15-3r = 3r+35-3r

Combine like terms

2r +15 = 35

Subtract 15 from each side

2r+15-15 =35-15

2r = 20

Divide by 2

2r/2 =20/2

r =10

5(r + 3) = 3r + 35
Remove parentheses
5r + 15 = 3r + 35
Move the terms
5r - 3r = 35 - 15
Collect like terms
2r = 20
Divide both sides
R = 10

Based on the regression output, which of the following is the predicted time, in minutes, that it took to gather the items if the order has 22 items?

Answers

Answer:

The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

Step-by-step explanation:

Regression Output :

Predictor Coefficient

Constant 3.0979

Square root of items 2.7633

R.sq.- 96.7%

So, with this data the regression equation is,

[tex]\hat{y}=3.0979+2.7633x[/tex]

Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items

Substitute x =22 in equation

[tex]\hat{y}=3.0979+2.7633(22)[/tex]

[tex]\hat{y}=63.8905[/tex]

Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

C. Distribute like terms

D. There is no such thing as a quadratic equation

Answers

Answer:

Answer A makes the most sense by far.

Step-by-step explanation:

Answer A makes the most sense by far. However, strictly speaking, the coefficient of x^2 does not have to be positive if we're using the quadratic formula. Using some other approach, such as factoring, obtaining a positive coefficient for x^2 is helpful.
