Answer:

4, 22  See below

Step-by-step explanation:

2x + y = 30

5x + y = 42

Subtract the first from the second

3x = 12

x = 4 so socks cost $4

Put that into one of the original equations

2x + y = 30

2(4) + y = 30

8 + y = 30

y = 22 slippers cost $22

Answer:

y=22

Step-by-step explanation:

Take the second statement as equation 1 and the first statement as equation 2 and subtract to eliminate y:

5x + y = 42

-(2x + y = 30)

--------------------

3x   + 0 = 12      --> x = 4

substituting x = 4 into 2x + y = 30  --> 8 + y = 30   --> y = 22

(x,y) = (4,22)

checking by adding the two equations substituting in (4,22)

20 + 22 = 42

8 + 22  = 30

---------------------

28 + 44 = 72

   72 = 72       √

The rectangle below is enlarged using a scale factor of 1.5. What will be the new length and width of the rectangle?
Likurg_2 [28]

When a shape is enlarged using a scale factor, you simply multiply each of the sides by the scale factor.

length = 3 * 1.5 = 4.5 m

width = 2 * 1.5 = 3 m
