Answer:

y=21

x=35

Step-by-step explanation:

Y+X=56

y=56-X

X/Y=5/3

X=5y/x

Y=56-(5y/3)

y+5y/3=56

y=21

56-21=x

x=35

Jade’s weekly paycheck is $306.25. She makes $8.75 per hour. Divide to find the number of hours per week Jade works.
ZanzabumX [31]

So if Jade makes $306.25 a week and for every hour she works, she makes $8.75, then all you have to do is divide 306.25 by 8.75.

306.25/8.75 = 35 hours should be your answer

Let me know if that doesn't make sense or you still don't understand it :)

A large rectangle is made by joining three identical small rectangles as shown.
vampirchik [111]

Answer: 35 cm

Step-by-step explanation:

As shown in the image attached, the A large rectangle is made by joining three identical small rectangles,

The width of one small rectangle is x cm and the length of one small rectangle is 2x cm. Therefore the perimeter of the small rectangle is given as:

2(length + width) = Perimeter

2(2x + x) = 21

2(3x) = 21

6x = 21

x = 21/6 = 3.5 cm

x = 3.5 cm

From the image attached, the width of the large rectangle is 2x (x + x) and the length is 3x (2x + x). Therefore, the perimeter of the large rectangle is:

2(length + width) = Perimeter

2(3x + 2x) = Perimeter

Perimeter = 2(5x)

Perimeter = 10x

Perimeter = 10(3.5)

Perimeter = 35 cm

Polygon X is similar to polygon Y. Polygon X is three times the size of polygon Y. The perimeter of polygon X is 81. What is the
maksim [4K]

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Polygon X is similar to polygon.

And Polygon X is three times the size of polygon Y.

So, it becomes,

\dfrac{\text{Perimeter of polygon X}}{\text{Perimeter of polygon Y}}=\dfrac{3}{1}\\\\\dfrac{81}{x}=\dfrac{3}{1}\\\\x=\dfrac{81}{3}\\\\x=27

Hence, perimeter of polygon Y is 27.

Therefore, Option 'C' is correct.

Bob believes his test grade varies directly with the number of hours he spends studying and inversely with the number of hours h
Readme [11.4K]

Answer: Hello mate!

A direct variation implies that, if y is the dependent variable that varies with the variable x; then: y = k*x where k is a real number.

An inverse variation has the form y = k/x where also k is a real number.

them, if we define s as the hours that Bob spends studying, and b as the hours that he spends playing baseball, then the equation that represents the score is:

Score(s,b) = k*s/b

we know that if s = 6, and b = 7, then the score is 72; with this information, we could obtain the value of the constant k.

score(6,7) = 72 =k*6/7 = k*

then  k = 72*(7/6) = 61.7

now if s = 4 and b = 6, the score that he should expect is:

score( 4, 6) = 61.7*(4/6) = 41
