marta [7]

Answer:

x = 4/7

Step-by-step explanation:

5/3 x = 20/21

Multiply by 3/5 on each side to isolate x

3/5 *5/3 x = 20/21 * 3/5

x = 20/21 * 3/5

Rewriting the right hand side

x = 20/5 * 3/21

x =4 * 1/7

x = 4/7

Oliver has a box of toy cars, but he is not sure how many he has. If he arranges the cars in groups of four, he has three left o

Zarrin [17]

X/4 = r3 or 3/4
x/3 = r2 or 2/3
x/5 = r3 or 3/5

we know x is not divisible by 4 3 or 5 and is less than 30.

we know the value ends in 3 or 8 from x/5 = r3

we know the value is greater than 3 from r3

so far we got 13 and 23

13 is eliminated from x/4 = r3 because it is r1 not r3

so the answer is 23
