A+b=82
a:b=9,r=2
a=b*9+2
9b+2+b=82
10b=80
b=8
a=8*9+2=72+2=74
Sper ca asta sa te ajute! :)
Avand in vedere ca aceasta este varianta pentru americani intrebarea ta ar trebui stearsa, pentru varianta in limba romana poti intra pe brainly.ro.Succes! ^^

Emma borrowed $89.40 from her sister. She determines that she can pay her back the total over six months. Which number reflects
omeli [17]

Answer:

$14.9

Step-by-step explanation:

Step one:

given data

we are told that Emma borrowed $89.40 from her sister to pay her back in 6 months.

let us solve for the amount she is to pay her sister every month.

amount to be paid per month= 89.40/6

=$14.9

So that every month she pays back her sister $14.9

we don't know her balance but every month there will be a deduction.

Hence the monthly change in her balance is reflected by a deduction of $14.9

Use the diagram at the right to answer questions 22–27.
kvv77 [185]

22. 30 degrees because line DB bisects(meaning cuts in half) angle ABC so DBC should be 30 degrees because 30+30 is 60 which is what angle ABC is.

23. 60 degrees because if we assume that it is a parallelogramand that the opposite angle are congruent.

24. 120 degrees because a quadrilatteral has sides that will equal to 360 degrees, and I said that a parallelogram will have its opposite angles congruent we take away 120 from 360 (from the previous angles ABC and BCD) we end up with 240, we divide 240 by 2 and end up with 120 degrees

25. 60 degrees. I found that angle DCB is 120 degrees so angles DCB and DCE are supplementary(add up to 180 degrees) and we subtract 120 from 180 which is 60 degrees.

26. 60 degrees vertical to angle DCE.

27. 120 degrees supplementary to DCE

Jenny is starting a cake baking business. She plans on selling each cake for $15 and her cost will be $5 per cake. The equipment
Gennadij [26K]
The domain is {0≤x≤200}.

This is because the domain is x, the number of cakes.  The smallest number of cakes she can bake is 0.

Since she is buying enough materials to make 200 cakes, this number is the largest number of cakes she can bake.
