First do 2 1/2 / 5/8

5/2/ 5/8=2/5 * 5/8=1/4

now you can do anything with 1/4 so

your answer is 1/4

$16.80 because $4.20 x 3 = $12.60 and $12.60 + $4.20 = $16.80

**Answer:**

28 cm

**Step-by-step explanation:**

For the similar figures, a proportion can relate the side lengths.

x/(7 cm) = 11.2/2.8

x = (7cm)(11.2/2.8) = 28 cm

**The value of x is 28 cm**.

**Answer:**

B

**Step-by-step explanation:**

Let point N has coordinates (0,0), then figure A has vertices at points (-3,0), (-7,0), (-7,4) and (-3,4). Figure B has vertices at points (3,1), (7,1), (7,-3) and (3,-3).

1. Translation 10 units to the right has the rule

(x,y)→(x+10,y).

Then vertices of the figure A have images:

- (-3,0)→(7,0);
- (-7,0)→(3,0);
- (-7,4)→(3,4);
- (-3,4)→(7,4).

2. Translation 3 units down has the rule

(x,y)→(x,y-3).

Then images are

- (7,0)→(7,-3);
- (3,0)→(3,-3);
- (3,4)→(3,1);
- (7,4)→(7,1).

As you can see these points are exactly the vertices of the figure B.

Your equation : 7-3 (2x-1)=2x×26

answer: x is equal to 5
