The required simplified expression for 9(m - 9) - 4(10m + 2) is -31m - 90.

Given that,
To rewrite in simplest terms: 9(m-9)-4(10m+2).

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Question asked to simplify the term 9(m-9)-4(10m+2).

= 9(m - 9) - 4(10m + 2)
= 9m - 81 - 40m - 8
= -31m - 90

Thus, the required simplified expression for 9(m - 9) - 4(10m + 2) is -31m - 90.

What is the answer to this math question

mezya [45]

Answer:

Step-by-step explanation:

1.80m + 0.6s = 12.00

[substitute the value of m into the equation]

1.80×(3) + 0.6s = 12

5.4 + 0.6s = 12

[make s the subject of the formula]

0.6s = 12 - 5.4

0.6s = 6.6

[divide both sides of the equation by 0.6]

0.6s / 0.6 = 6.6 / 0.6

s = 11

To prove that 11 is correct

[substitute the value of m and s into the equation]

1.80m + 0.6m = 12.00

1.80×(3) + 0.6×(11) = 12.00

5.4 + 6.6 = 12.00

12.00 = 12.00

jenny borrowed $500 for 5 years at 4% interest compounded annually. what is the total amount she will have paid when she pays of

alexdok [17]

Use the formula for compound interest,

$A=P(1+ \frac{r}{n})^{nt}$

Where P is the starting amount (500$), r is the rate of interest (0.04), n is the number of times the interest is compounded per unit (1 per year), and t is the amount of time it is compounded (5 years).

Now, plug it into the formula:

$A=500(1+ \frac{0.04}{1})^{5}$

Do the math, and your answer is she must pay <span>608.32$ when she pays her debts.</span>

The ratio of the number of boys campers to the number of girl campers was 8:7. if there were a total of 195 campers, how many bo

cestrela7 [59]

Imagine for a group of 15 (8 boys and 7 girls), you will have 8 girls. So the ratio of girls to total campers is 8/15
Because we have 195 campers, we have 8/15 = x/195
solve for x
x= 104 girls
and we have 195 - 104 = 90 boys
