What is the m<BEC if m<AED = 179?

ra1l [238]

m∠AED = m∠AEB + m∠BEC + m∠CED

179 = 105 + x + 40

x = 179 - (105+40) = 34

x = 34

5y + 3 > -7 + 13 how do i do this

ASHA 777 [7]

5y + 3 > -7 + 13

First add -7 + 13 = 6

5y + 3 > 6

Subtract 3 from both sides

5y + 3 -3 > 6 - 3

5y > 3

Divide both sides by 5

5y/5 > 3/5

y > 3/5

Guidance counselors in a school would like to determine whether studying Latin helps students achieve higher scores on the verba

mojhsa [17]

Answer:

Step-by-step explanation:

1. This paragraph describes an observational study.

It is not a controlled experiment because the guidance counselors didn't plan to separate the students into 2 groups and then observe the results. They instead checked records.

2. The students who took Latin are the treatment group.

3. The fact that students decided on their own to take Latin is a confounding factor.

4. The students who did not take Latin are the placebo or control group.

4. Write an equation for the line that is parallel to the given line and that passes

pentagon [3]

Answer:

$y=\frac{5}{2}x-14$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

1) Determine the slope (m)

$y=\frac{5}{2}x-10$

In the given equation, $\frac{5}{2}$ is in the place of m, making it the slope. Because parallel lines have the same slope, the line we're currently solving for therefore has a slope of $\frac{5}{2}$ . Plug this into $y=mx+b$ :
