8 0

Answer:

(8,0)

Step-by-step explanation:

First equation

2 x- 4y = 32

2 x = 32 + 4 y

x = 32 + 4 y DIVIDED BY 2

x = 32/ 2 + 4 y/ 2

x = 16 + 2 y

Second equation

8 x − 8 y = 96

Factorize

8 ( x − y ) = 96

Transfer the 8 and put value of x

16 + 2 y − y = 96 /8

16 + y = 12

y = 12 − 16

y = − 4

Get the value of x

x = 16 + 2 y

x = 16 + 2 × − 4

x = 16 + ( − 8 )

x = 8

Sam was given a bag of 100 red and blue marbles. He believes

Rashid [163]

Answer:

(D) There are probably more blue marbles than red marbles in the bag.

Step-by-step explanation:

There are a total of 100 marbles in the bag.

In the experiment of 50 trials, Sam had the following outcome:

Blue=35

Red=15

Relative Frequency of Blue Marbles =35/50=0.7

Relative Frequency of Red Marbles =15/50=0.3

Since the relative frequency of blue marbles is greater than the relative frequency of red marbles, there are probably more blue marbles than red marbles in the bag.

The correct option is D.

Two mechanics worked on a car. The first mechanic charged $95 per hour, and the second mechanic charged $60 per hour. The mech

Yanka [14]

Answer:

Mechanic A worked for 5 hours and Mechanic B worked for 15 hours

I hope my answer and explanation helped!

okay to get started you need to make a system of equations:

x= number of hours worked by mechanic A

y= number of hours worked by mechanic B

x + y= 20

95x + 60y= 1375

substitute in an equation:

x + y= 20

y= 20- x

95x + 60(20-x)=1375

Solve for x

95x + 1200 - 60x=1375

35x =175

x= 5

plug in x to solve for y

x + y= 20

5 + y= 20

y=15

Check work

then you're done :D
