Answers

Answer 1
Answer:

Answer:

20

Step-by-step explanation:

She volunteers for hours on each week day = 2

No. of week days = 5

So, She volunteers for hours on 5 week day = 5 * 2

On Saturday and Sunday, she volunteers 3 hours more each day.

So, on weekend She volunteers for hours on each day = 2+3 = 5 hours

No. of days in weekend = 2

So, She volunteers for hours on weekend 2 * 5

So,  the number of hours she volunteers in one week:

=  5 * 2+2 * 5

= 20

Hence the number of hours she volunteers in one week is 20
Answer 2
Answer: 2 (hours) × 5 (weekdays) + 10 ( total number of hours on weekend )

A student gets 68 marks n therefore gets 85 percent total marks are?

Answers

Answer:

There are 80 marks in total.

Step-by-step explanation:

Let the number of total marks be x.

The percentage score of the student can be written as the ratio

\displaystyle (68)/(x) = 85\%.

However,

\displaystyle 85\% = (85)/(100).

Equating the two:

\displaystyle (68)/(x) = (85)/(100).

Cross-multiply (that is: multiple both sides by 100x, the product of the two denominators) to get

85x = 68* 100.

\displaystyle x = (68* 100)/(85) = 80.

In other words, there are 80 marks in total.

Algebra 1 Solving Linear Expressions.What is 9x-6=-3x+30?

Answers


The answer is x=6.     9x-6=3x+30

                                    9x-3x-6=3x-3x+30

                                     6x-6=0 +30

                                     6x-6 + 6= 0 + 30 +6

                                     6x=36

                                      6x/6=36/6

                                         x=6
