practice:\ntranslate the sentences below into an equation. then solve each equation.\n1. 70 is 40% of what number?\nequation:\nsolve:
Answer
Explanation:
Step1: Define variable & translate to equation
Let $x$ be the unknown number. Convert 40% to decimal form: $40% = 0.4$. The equation is: $70 = 0.4x$
Step2: Isolate the variable $x$
Divide both sides by 0.4: $x = \frac{70}{0.4}$
Step3: Calculate the value of $x$
$x = 175$
Answer:
The equation is $70 = 0.4x$, and the unknown number is 175.
