Joanie decides to buy matching sweaters for herself and her 3 sisters. The regular price of the sweaters is $37. Joanie says if
Roman55 [17]

Answer:

Yes, it is possible if the sweaters on sale are $7.40 each.

Step-by-step explanation:

The sweaters each cost $37. To purchase all four (for herself and 3 sisters) without a sale would be 4(37)= $148.

40% off the regular price would be 0.40(148)= $59.20 savings. She would spend 148-59.2= $88.80.

Is it possible to buy two regular price sweaters and two on sale for $88.80?

2(37)=$74. If we subtract from the sales total, 88.80-74=14.80. This means the two sweaters on sale must each be $7.40. It is possible to save 40%.

Q26. Division A has 15 students and division B has 20 students. Average score of students in division A is greater by 2 as compa
Romashka [77]

Step-by-step explanation:

Let a be the total score of Div. A

Let b be the total score of Div. B

given,

\frac{a}{15}  -  \frac{b}{20}  = 2

as equation 1.

and

b - a = 160 \\  - a + b = 160

as equation 2.

Now multiply equation 2 by 1/20 to eliminate b to solve for a.

( - a)( \frac{1}{20} ) + (b)( \frac{1}{20} )  = ( \frac{1}{20} )(160) \\  -  \frac{a}{20}  +  \frac{b}{20}  = 8

take this new equation as equation 3.

now we will use equation 1 + equation 3 to eliminate b to solve for a.

( \frac{a}{15}  + ( -  \frac{a}{20} )) + (  - \frac{b}{20}  +  \frac{b}{20} ) = 2  +  8 \\  \frac{a}{60}  =  10 \\ a = 60 \times 10 \\  = 600

Div.A total score = 600

Average Score = Total Score / Number of students.

\frac{600}{15}  \\  = 40

I need to know how to do this ?
Norma-Jean [14]
When you add the degrees of all the angles in a triangle you should get 180

A= 5x+5
B= 90
C= 3x+5

5x + 3x = 8x
5 + 90 + 5 = 100

8x + 100 = 180 this is the equation
-100 -100
————————
8x = 80 ➡️ divide BOTH sides by 8

x = 10

Now plug 10 into angles A and C

5(10)+5= 55
3(10)+5= 35

A= 55 , B= 90 , C=35
