stealth61 [152]3 years ago
8 0

Answer:

It has infinite solutions.

D. More than 1 solution

Step-by-step explanation:

$\left \{ {{3y - 9x = -6} \atop {5y - 15x = -10}} \right. $

$\left \{ {{3y(-5) - 9x(-5) = -6(-5)} \atop {5y(3) - 15x(3) = -10(3)}} \right. $

$\left \{ {{-15y +45x = 30} \atop {15y - 45x = -30}} \right. $

0+0=0

or

5y = 15x - 10\\y = 3x - 2

3(3x-2) - 9x = -6

0=0

Which pair represents equivalent ratios?
TEA [102]

Answer:

D

Step-by-step explanation:

We can test each pair making each ratio into its simplest form.

For A 2/3 is already in its simplest form and 9/15=3/5. they are not equivalent.

For B, 5/8 is already in its simplest form and 15/21=5/7. they are not equivalent.

For C, 3/12=1/4, and 6/18=1/3. They are not equivalent.

For D, 4/10=2/5, and 12/30=2/5. They are equivalent.

Solve 6 2/3 -1 1/2+4 1/6​
Tju [1.3M]

Answer:

9 1/3

Step-by-step explanation:

Make 2/3 , 1/2 , & 1/6 have the same denominator. 6 is the least common multiple for all 3 fractions.

2/3 gets multiplied by 2/2

1/2 gets multiplied by 3/3

1/6 stays the same

2/3 becomes 4/6

1/2 becomes 3/6

1/6 stays 1/6

Follow the order of operations from the original equation.

4/6 - 3/6 = 1/6 then 1/6 + 1/6 = 2/6

6 - 1 = 5 then 5 + 4 = 9

Simplify 2/6 to 1/3

Remember to add 1/3 back to 9 making it 9 1/3
