Simplify first using the inverse of subtraction or addition. Simplify further by multiplication or division. you will multiply only if you have a variable in a fraction such as 1/a just multiply by 1. You divide to get a variable by itself such as 2a you divide by 2 to get a by itself. Hope this helps...

-7m+4< -45 for solving an inequality

worty [1.4K]

Solving the inequality $-7m+4< -45$ we get $m>7$

Step-by-step explanation:

We need to solve the inequality: $-7m+4< -45$

Solving:

$-7m+4< -45$

Adding -4 on both sides:

$-7m+4-4< -45-4$

$-7m< -49$

Divide both sides by -7 and reverse the inequality:

$\frac{-7m}{-7}>\frac{-49}{-7}$

$m>7$

So, solving the inequality $-7m+4< -45$ we get $m>7$

What is the ratio of a to b 9/17= 3a/ a+b 3/14 6/17 13/17 50/9

Anarel [89]

Answer:

3/14

Step-by-step explanation:

We want to find the ratio of a to b, or a/b

9/17 = 3a/ (a+b)

Multiply each side by 17

17*9/17 =17* 3a/ (a+b)

9 = 51 a/ (a+b)

Multiply each side by (a+b)

9 (a+b) = 51a

Distribute the 9

9a +9b = 51a

Subtract 9a from each side

9a-9a +9b =51a-9a

9b = 42a

Divide each side by b

9b/b = 42a/b

9 = 42a/b

Divide each side by 42

9/42 = a/b

But we can simplify 9/42 because each is divisible by 3, so divide 9 and 42 by 3

3/14 = a/b
