Answer:

4(11y +22)

Step-by-step explanation:

5(9y+19.8) =45y+99

9(5y+11)=45y+99

2(22.5y+49.5)=45y+99

4(11y+22)=44y+88

you must expand the numbers to get the total

for example you multiply 5×9y and 5×19.8 in a

Good morning,

Answer:

Step-by-step explanation:

5+(-4) = 5 - 4 = 1

-4 + (-7) = -(4+7) = -11

since 1 > -11 then 5+(-4) > -4 + (-7)

Grace and her brother Sid want to raise money to go to band camp. Their parents have agreed to help them earn up to $400 by payi

LenKa [72]

Answer:

25m + 10b = 400

Step-by-step explanation:

Total amount that can be earned = $ 400

Amount earned on mowing a lawn = $ 25

Amount earned per hour on babysitting = $10

Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25m

Amount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b

Total amount earned = Amount earned from mowing m lawns + Amount earned from babysitting for b hours

Using the values from above, we can set up the equation as:

400 = 25m + 10b

25m + 10b = 400

This equation represents the number of lawns they can mow, m, and hours they can babysit, b, to earn $400.

How do you solve for sides a and b of a triangle when you know the value of c?

sasho [114]

Assuming you have some angle measures, you could use the Law of Sines to solve for the missing side lengths, which states that,
$\frac{a}{sinA}= \frac{b}{sinB}= \frac{c}{sinC}$ ,
where a, b, and c correspond to the given sides you have, and A, B, and C represent the angles you have.

In this scenario, you would have to have the values for c (which we do), and have the angle measure of C. In addition, we would also need an angle measure that is either A or B.

Hope this helps a bit!
