Solve for x
5(x+8)=2x−7+8(x−1)
Answers
Answer:
x = 11
Step-by-step explanation:
5(x+8) = 2x - 7 + 8 (x - 1)
5x + 40 = 2x - 7 + 8x - 8
5x + 40 = 2x + 8x - 7 - 8
5x + 40 = 10x - 15
40 + 15 = 10x - 5x
55 = 5x
5x = 55
x = 55/5
x = 11
x=11
Step-by-step explanation:
5x+40=2x-7+8x-8
5x+40=10x-15
10x-5x=40+15
5x=55
x=55/5
x=11

Answers
Answer:
D.No solution
Answer:
C
Step-by-step explanation:
-2(x + 3) = -2x - 6 Remove the brackets
-2x - 6 = -2x - 6
Since the left and right sides are equal, any number will work.
If you wind up with a false statement, then there are no solutions.
2x + 4 = 2x + 7 Subtract 2x from both sides.
4 = 7

In grade 10, the ratio of boys to girls is 2: 3. There are 75 girls. How many are boys?
HELP PLEASE .. I WILL GIVE A BRAINLIEST !
Answers
Answer:
150
Step-by-step explanation:
The ration is 2/3 in this example means they are twice as many boys than girls. If boys = 2/3, than girls = 1/3.
So, to find the answer, you must multiply 75 by 2, which is 150.
You don't need this, but they are 75 + 150 = 225 boys and grils in grade 10.

6.2 Margin of error and the confidence interval. A study of stress on the campus of your university using the College Undergraduate Stress Scale (CUSS) reported an average stress level of 1123 (a higher score indicating more stress) with a margin of error of 43 for 95% confidence. The study was based on a random sample of 400 undergraduates. a. Give the 95% confidence interval. b. If you wanted 99% confidence for the same study, would your margin of error be greater than, equal to, or less than 43
Answers
Using confidence interval concepts, it is found that:
a. The 95% confidence interval is (1080, 1166).
b. The margin of error would be greater than 43.
Item a:
The interval is the sample mean plus/minus the margin of error, hence:
[tex]1123 - 43 = 1080[/tex]
[tex]1123 + 43 = 1166[/tex]
The 95% confidence interval is (1080, 1166).
Item b:
The margin of error is direct proportional to the critical value.The higher the confidence level, the higher the critical value, and thus, the higher the margin of error.Hence: The margin of error would be greater than 43.

Answer:
1. (x - 1) × (x + 3)
2. x = 3 and y = -2
Step-by-step explanation:
x² + 2x - 32x + 3y = 0; y = 3x - 11rewrite the equation:
y = 3x - 11; 2x + 3y = 0
solve y = 3x - 11 for the y:
y = 3x - 11
substitute 3x - 11 for y in 2x + 3y = 0;
2x + 3y = 0;
2x + 3y = 0
2x + 3 (3x - 11) = 0
11x - 33 = 0 (simplify both sides of the equation)
11x - 33 + 33 = 0 + 33 (add 33 to both sides)
11x = 33
11x/11 = 33/11 (divide both sides by 11)
x = 3
subtitute 3 for x in y = 3x - 11
y = 3x - 11
y = (3)×(3) - 11
y = -2
I showed one equation because the other is self explanatory, hope this helps.
Given the following PARALLELOGRAM, find the measure of each angle below.
Answers
Answer:
m∠BEC = 65°
m∠DEC = 115°
m∠DAE = 78°
m∠ECD = 40°
m∠BAD = 118°
m∠ADC = 62°
Step-by-step explanation:
m∠BEC = 65°
Opposite angles formed by intersecting lines are congruent
m∠DEC = 180 - 65 = 115°
A straight line has a degree measure of 180
m∠DAE = 78°
Opposite interior angles of two parallel lines cut by a transversal are congruent
m∠ECD = 180 - [m∠DEC + 25] = 40°
Sum of angles inside triangle ECD has a measure of 180
m∠BAD = 78 + m∠ECD = 118°
Opposite angles of a parallelogram are congruent
2(m∠BAD) + 2(m∠ADC) = 360
118 + m∠ADC = 180
m∠ADC = 62°
Sum of angles inside a parallelogram = 360°
