Using property find a.3/5×-2/7+4/5-3/10×2/7​

Mathematics
1 answer:
Sedaia [141]3 years ago
5 0

Here the answer is 19/35

Step-by-step explanation:

\frac{3}{5} X\frac{-2}{7} +\frac{4}{5}-\frac{3}{10} X\frac{2}{7}

We will apply BODMAS rule

In this rule multiplication comes before add and subtraction

= \frac{-6}{35} + \frac{4}{5} - \frac{3}{35}

= \frac{4}{5} - ( \frac{6}{35}+ \frac{3}{35})

= \frac{4}{5} -  \frac{9}{35}

= \frac{4 X 7}{5 X 7} -\frac{9}{35}

= \frac{28}{35} - \frac{9}{35}

= \frac{19}{35}

Which of the following is the correct graph of the solution to the inequality-18>-5x+2>-48
makvit [3.9K]

Answer:

Step-by-step explanation:

we have

18 > -5x+2 > -48

This is a compound inequality

Remember that

A compound inequality i can divide in a system of two inequalities

so

18 > -5x+2 -----> inequality A

-5x+2 > -48 ---> inequality B

step 1

Solve the inequality A

18 > -5x+2

Multiply by -1 both sides

-18< 5x-2

-18+2< 5x

-16< 5x

Divide by 5 both sides

-3.2< x

Rewrite

x > -3.2

The solution of the inequality A is the interval ----> (-3.2,∞)

step 2

Solve the inequality B

-5x+2 > -48

Multiply by -1 both sides

5x-2 < 48

5x < 48+2

5x < 50

Divide by 5 both sides

x < 10

The solution of the inequality B is the interval ----> (-∞, 10)

step 3

Find the solution of the compound inequality

(-3.2,∞) ∩ (-∞, 10)=(-3.2,10)

All real numbers greater than -3.2 and less than 10

A student scores 73 out of 100 on a test. If the maximum score on the next test is also 100​ points, what score does the student
vesna_86 [32]
Because the student scored 73/100 on the first test, their current average is 73%.

To calculate the avergae with the next test score, you add both percentages the student gets together and then divide by 2.

79 = (73 + x) / 2

Multiply by 2 on both sides

158 = 73 + x

Subtract 73 on both sides

x = 85

So the student needs to get at least an 85/100 on the next test to maintain a 79 average.
