Use the order of operations to simplify<br> 5*3 to the second power-15/5

ASHA 777 [7]

Assuming the question reads:

$5 \cdot 3^2 - 15 \div 5$

The order of operations is as follows:

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

There are no parentheses in the equation.

There is an exponent in the equation. Solve this term first:

$3^2 = 9$

The equation should now read:

$5 \cdot 9 - 15 \div 5$

There are two multiplication/division operations in the equation. Solve them individually:

$5 \cdot 9 = 45$

$15 \div 5 = 3$

The equation should now read:

$45 - 3$

There is one subtraction operation. Solve this term for your answer:

$45 - 3 = \boxed{42}$

The equation 4 ( x - 2 ) = 100 is a true equation for a particular value of x. Explain why 2 ( x - 2 ) = 50 is also true for the

KatRina [158]

Answer:

a) 4(x - 2) = 100

4x - 8 = 100

4x = 92

x = 23

b) 2(x - 2) = 50

2x - 4 = 50

2x = 46

x = 23

Step-by-step explanation:

When solving for x in both equations, we get the same value of x which makes that statement true.
