Determine whether each pair of ratios are equivalent. Explain (3/5),(9/15)

1 answer:

6 0

Multiple both ratios by a least common denominator
the least common denominator for both is 15
multiply the first ratio by 3/3
9/15=9/15
both are equal because when multiplying by the least common denominator you get the same answer

That is true because the square root of 32 is about 5.66, so 4.65 IS less than it.

Two cyclists, 55 miles apart, start riding toward each other at the same time. One cycles 5 miles per hour faster than the other

tangare [24]

Answer:

r = 6 mph and f = 11 mph

Step-by-step explanation:

Representations:

1) speed of faster cyclist: f = r + 5

2) speed of slower cyclist: r

Distances covered:

(r + 5)(5 hr) + r(5) = 55 mi (total distance covered)

Then 5r + 25 + 5r = 55, or, after reducing this equation:

r + 5 + r = 11, or

2r = 6

Then r = 6 mph and f = 11 mph

Tiana solved the equation

LenaWriter [7]

Answer:

actually when I solved it ,the equation is true

Step-by-step explanation:

look

-2 (3x - 5) = 4(x + 3) + 8

-6x + 10 = 4x + 12 + 8

-6x + 10 = 4x + 20

-6x - 4x = 20- 10

-10x = 10

x = -1

and when I substitute, I get 16 on both sides so I don't know where the problem is
