Answer: -21/2
Concept:
Usually, when doing mathematics operation, it goes by the PEMDAS order:
- Parenthesis
- Exponent
- Multiplication
- Division
- Addition
- Subtraction
However, since the question asks to solve the order of operation from left to right, then we would be doing [addition] --> [Divison]
Solve:
<u>Given</u>
(-5/2) + 3/4 ÷ 1/6
<u>Operate with addition</u>
=(-10/4) + 3/4 ÷ 1/6
=(-7/4) ÷ 1/6
<u>Operate with division</u>
=(-7/4) × 6/1
=-42 / 4
=-21 / 2
Hope this helps!! :)

Answer:
See solution below
Step-by-step explanation:
According to the diagram shown
m<1 = m<5 = 5=65 degrees (corresponding angle)
m<5 = m<4 - 65 degrees (alternate interior angle)
m<9 = m<8 = 65degrees (corresponding angle)
m<5 = m<8 = 65dgrees (vertically opposite angles)
m<6+m<8 = 180
m<6 + 65 = 180
m<6 = 180 - 65
m<6 = 115degrees
m<2 = m<6 = 115degrees (corresponding angles)
m<6 = m<7 = 115degrees (vertically opposite angles)
m<3 = m<7 = 115degrees(corresponding angle)
)
The equation to find percent error is
where actual is the value that actually came out (in this case, 11.5 km) and theoretical is the value that was supposed to come out (in this case, 10 km). Just plug in the numbers and simplify.
So, the true answer would be 15%. Apparently, the question you're asking takes 11.5 as the theoretical and the 10 as the actual (which I personally disagree with)
If you plugged in the numbers that way, the answer comes out to 13.04%. So, the correct answer for your answer choices is c. 13%
Hi there!

I believe your answer is:
(-3, -1) and (1, 3)

Here’s why:
- I have graphed the two equations given on a graphing program.
- When graphed, they pass at points (-3, -1) and (1,3). Therefore, they are the solutions to the system.

Hope this helps you. I apologize if it’s incorrect.
Sum of angles in a triangle = 180
2x – 5 + <span>3x + 10 + 90 = 180
5x + 95 = 180
5x = 85
x = 17
</span>2x – 5 = 2(17) - 5 = 29
3x + 10 = 3(17) + 10 = 61
