An equivalent ratio refers to the same number but written differently. For example, for the ratio 6/9, we could obtain the following equivalent ratios.

First equivalent ratio

You can divide the numerator and denominator by 3. You get 2/3

$\frac{6\div 3}{9\div 3}=\frac{2}{3}$

Second equivalent ratio

You can multiply the numerator and denominator by 2. You get 12/18

$\frac{6\times 2}{9\times 2}=\frac{12}{18}$

Third equivalent ratio

You can multiply the numerator and denominator by 3. You get 18/27

$\frac{6\times 3}{9\times 3}=\frac{18}{27}$

Thus, three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27

Answer:

1. x=-3

2. m=4

3. -6=b

4. x=3

Step-by-step explanation:

1. 7(3-3x)=84 what is x

- Distribute the 7 using distributive property, which will give you 21-21x=84.

- Add 21 to both sides to aim to isolate the x variable, which will give you -23x=63.

- Divide both sides by the coefficient of x, -23, to finally get x by itself: x=-3

2. -7(-4-3m)=112 what is m

- Distribute the -7 using distributive property, which will give you 28+21m=112. Be wary of negatives.

- Subtract 28 to both sides, which will give you 21m=84.

- Divide both sides by 21 (the coefficient of m) to get m by itself: m=4

3.-182=7(2b-8)+7b what is b

- Distribute the 7 using distributive property, which will give you -182=14b-56+7b

- Add like terms to get -182=21b-56.

- Add both sides by 56, which will get you -126=21b.

- Divide both sides by the coefficient of b, 21, to get b by itself: -6=b

4. -101 = -5(8x-5) -6 what is x

- Distribute the -5 using distributive property, which will give you -101=-40x+25-6. Beware of negatives.

- Add like terms to get -101=-40x+19.

- Subtract both sides by 19 to get -120=-40x.

- Divide both sides by 40 (the coefficient of x) to get 3=x.

Hope this helps!

Jeremy caught 8 fish in a contest.

seraphim [82]

Answer:

3.1 kg

Step-by-step explanation:

4.3+5.3+ 6.8+ 2.6 + 3.2 +4.4 +4.8= 31.4 kg

Last fish= y

(31.4 + y)÷ 8= 4.3125

31.4 + y= 4.3125 x 8

y= 34.5 - 31.4

∴ y= 3.1 kg
