Question

one of the giraffes, bemard, is sick. last week he weighed 2,490 pounds. this week he weighs 2,312 pounds. if w represents the amount of weight lost, use the bar diagram to write an equation and find the amount of weight bemard lost.
the equation used to solve the equation is
the amount of weight bemard lost is

Explanation:

Step1: Write the equation

From the bar - diagram, we know that the initial weight (2490) is equal to the current weight (2312) plus the weight lost ($w$). So the equation is $2312 + w=2490$.

Step2: Solve the equation for $w$

Subtract 2312 from both sides of the equation.

$$w = 178$$

Answer:

The equation used to solve the problem is \(2312 + w = 2490\). The amount of weight Bernard lost is \(178\) pounds.
