Answer:

must practice 7 hours on Saturday

Step-by-step explanation:

Let 'x' = number of hours on Saturday

(5 (hours) + x) / 6 (days) = 2

\frac{5+x}{6} = \frac{2}{1}

Cross-multiply to get 5 + x = 12

Answer:

7 hours

Step-by-step explanation:

First find the total number of hours she practices based on the average of 2 hours a day for six days.

This means 6*2 = 12 , she practices a total of 12 hours.

Next find the total hours she already practiced. She practices 1 hour a day from Mon to Fri, which is 5 days, so 1*5 = 5 hours. This is the hours she practiced already.

To meet the mean, she needs to practice 12-5 = 7 hours more on Saturday.

(49.44-232.91)+(-283.29)=-466.76

-283-(232.91+49.44)=-565.35

Ali simplifies the expression 9y+y to 9y2. Use the drop-down menus to complete the statements below to explain why Ali's solutio
maxonik [38]

Ali's solution is incorrect.

Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong.

Step-by-step explanation:

Ali simplifies the expression 9y+y to 9y2. We need to identify if Ali's solution is correct or incorrect.

Ali's solution is incorrect.

Reason:

We are given the expression: 9y+y

When we add two like terms ( terms having the same variable and exponent), we add the coefficients of both like terms.

In our case 9y+y = 10y

Whereas Ali has done multiplication of both terms and not addition.

In multiplication we add the exponents of the same variables i.e 9y+y = 9y^2

So, Ali had to add both the terms and should get 10y answer, and not multiply both terms and get answer 9y^2 which is wrong.
