Answer:
Equation: x + 16 + 13 + x = 21 ; x = -4
Step-by-step explanation:
x + 16 + 13 + x = 21 (Given)
2x + 29 = 21 (Added like terms)
2x = -8 (Subtracted 29 on both sides)
x = -4 (Divided 2 on both sides)
First off hmm <span>26°1' is just 26 degrees and 1 minute
there are 60 minutes in 1 degree, so 1minute is just 1/60 degrees
so </span>26°1' is 26° + (1/60)° or 26.1667 rounded up, since 1/60 is a recurring unit
alrite... so hmm, check the picture below
make sure your calculator is in Degree mode.
You have to add 1 1/4 + 1 3/4. Since they have common denominators you can just add all the numbers, 1+1=2, 1+3=4 since 4/4 is equal to one, you would add a one to the 2, so the answer would be 3. So Ed spent 3 hours doing homework during the weekend.
The percentage of published studies that supported the tested hypothesis has changed from 70 to 85% over the past 25 years.
Hypothesis testing:
A hypothesis testing means investigates a proposed mathematical model to determine whether there is sufficient evidence from a sample of data to reject the defined null hypothesis.
Given,
The percentage of published studies that supported the tested hypothesis has changed from _____ to _____ over the past 25 years.
Here we need to find the change in the percentage for the past 25 years.
Based on the details, the percentage of published studies that supported the tested hypothesis has changed from 70 to 85% over the past 25 years.

Answer:
y = -3x + 9 is your answer.
Step-by-step explanation:
So your y-intercept is the slope. Here is the equation we are going to use:
y - y_1 = m(x - x_1)
y_1 = 0
x_1 = 3
m = -3.
y - 0 = -3(x - 3)
y - 0 = -3x + 9
y = -3x + 9 is your answer.
