Using each of the digits 0-6 only once, make two equivalent ratios

The two equivalent ratios are 8:4 and 2:1

Step-by-step explanation:

The digits taken are 4 and 2.

Therefore, 4:2 = 4 x 2:2 x 2

So one equivalent ratio is 4:2 = 8:4

For the other equivalent ratio, 4:2 = 4 /2:2/2

Hence, the other equivalent ratio is 4:2 = 2:1

Finally, the two equivalent ratios are 8:4 and 2:1

A ratio obtained by multiplying or dividing the numerator and denominator of a given ratio by the same number is called an equivalent-ratio.

A ratio is a comparison of two quantities by division. Ratios describe a part-to-part comparison or a part-to-whole comparison. Ratios are written three ways: as a fraction, with a colon, and with the word “to.” The ratio for quantity a to quantity b is: a/b or a:b or a to b. Consequently, a ratio may be considered as an ordered pair of numbers, as a fraction with the first number in the numerator and the second as denominator, or as the value denoted by this fraction. Ratios of counts, given by (non-zero) natural numbers, are rational numbers, and may sometimes be natural numbers. When two quantities are measured with the same unit, as is often the case, their ratio is a dimensionless number. A quotient of two quantities that are measured with different units is called a rate.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

if x = 1, then the answer is 3.5
