Evaluate the following expression. (-5+ 7 x 1) - 9 x 5

-43

Step-by-step explanation:

(-5+7*1)-9*5  ---> * is muliplication sign

(-5+7)-45 --->multiplications first

(2)-45---> next the parantheses

-43 ---> the answer!!!

  -43

Explanation:

We'll use PEMDAS here.

Focus on the stuff in the parenthesis first. We multiply 7 and 1 to get 7*1 = 7

Then we add on -5 getting -5+7 = 2

The stuff in the parenthesis turns into 2

We go from this

(-5+7*1) - 9*5

to this

2 - 9*5

From here we multiply 9 and 5 to get 45, then subtract like so

2-45 = -43

So here's the step by step picture

(-5 + 7*1) - 9*5

(-5 + 7) - 9*5

(2) - 9*5

2 - 9*5

2 - 45

-43

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
