Use the order of operations to evaluate: −7.6 − 2[9 + (−6.8)] First, simplify the parentheses: [9 + (−6.8)] = 2.2. Now the expression is: −7.6 − 2(2.2)

Since there are no exponents in this problem, the next step is 1. (- 7.6)2.2 2. (- 7.6) – 2 3. (- 2)2.2 4. 2.22

Simplify the previous step and you get 1. -7.6(-4.4) 2. -7.6 + 2.2 3. -7.6 + 4.4 4. -7.6-4.4

The final answer is

-12 should be the answer :D

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
