15 similar blouses and 2 similar skirts cost $505. 5 such blouses and 2 such
Luden [163]

Answer:

Cost of five blouses = $145

Step-by-step explanation:

Let

x = cost of blouse

y = cost of skirt

15x + 2y = 505 (1)

5x + 2y = 215 (2)

Subtract (2) from (1) to eliminate y

15x - 5x = 505 - 215

10x = 290

x = 290/10

x = 29

Substitute x = 29 into (2)

5x + 2y = 215 (2)

5(29) + 2y = 215

145 + 2y = 215

2y = 215 - 145

2y = 70

y = 70/2

y = 35

x = cost of blouse = $29

y = cost of skirt = $35

How much do 5 such blouses cost?

cost of a blouse = $29

Cost of five blouses = $29 × 5

= $145

Cost of five blouses = $145

What is the least common denominator of 7/10 and 4/9
melisa1 [442]

Answer:

7/10 = 63/90

4/9 = 40/90

Step-by-step explanation:

Rewriting input as fractions if necessary:

7/10, 4/9

For the denominators (10, 9) the least common multiple (LCM) is 90.

LCM(10, 9)

Therefore, the least common denominator (LCD) is 90.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

7/10 = 7/10 × 9/9 = 63/90

4/9 = 4/9 × 10/10 = 40/90
