-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 $m>7$

Fudgin [204]

Since we know that the ratio of the model car to the real car is 1:64, therefore we use this to solve this true length of the real NASCAR vehicle, let us call this us X, so that:

1 : 64 = 3 inches : X

1 / 64 = 3 inches / X

X = 192 inches

The true length is 192 inches</span>
