Andy is one-fourth as old as his grandfather, who is 76 years old. Write an equation to determine whether Andy is 19 or 22 years old.

Answers

We know that if we multiply Andy's age by four we obtain 76. Lets assume that Andy's age its x. so
4*x=76
Now we have to solve equation
4*x=76 /:4 divide both sides by 4
x=19 - its the answer

A=Andy
G=Andy's Grandfather

A*4=G
G=76
A*4=76
/4
a=19

Answers

Answer:

$\sf 7.0 * 10^(-6)$

Step-by-step explanation:

Writing in standard form or scientific form:

0.000007

As we have to move the decimal point to right, the power of 10 will be negative and as the decimal point is moved 6 times to the right, the power of 10 is (-6).

0.000007 = 7.0 *10⁻⁶

Answer: 7.0 *10⁻⁶
