three times a number subtracted by 3 is 20
Answer:
3x - 3 = 20
Step-by-step explanation:
Times is a word that represents multiplication. A number can be represented by x.
3x - 3 = 20
Solving this:
3x - 3 = 20 1. Add 3 on both sides
3x = 23 2. Divide by 3 on both sides
x = 7 2/3

What is the slope of the line?
Answer: Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.
Step-by-step explanation:
Answer:
slope = [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 4) ← 2 points on the line
m = [tex]\frac{4-(-3)}{3-(-1)}[/tex] = [tex]\frac{4+3}{3+1}[/tex] = [tex]\frac{7}{4}[/tex]

What is the y=mx+b of the equation x+3y=−15
Answer:
y = -1/3x - 5
Step-by-step explanation:
First, we need to get y by itself so we subtract x from both sides, giving us: 3y = -x - 15
Secondly, we need to isolate the y, so we divided the 3 out on both sides giving us: y = -1/3x - 5 which is our answer.

Step-by-step explanation:
Carlos has 2 dollars more than half of the total amount of money his brother has. If x represents the amount of money Carlos's brother has, which expression can be used to represent this situation?
Answer:
[tex]y = 2 + \frac{1}{2}x[/tex]
Step-by-step explanation:
Given
Represent Carlos with y and his brother with x.
Analysing the statement one after the other:
Half of his brother's amount is: [tex]\frac{1}{2}x[/tex]
$2 more: means we add 2 to [tex]\frac{1}{2}x[/tex]
So, we have: [tex]2 + \frac{1}{2}x[/tex]
The above represent Carlos's amount.
So, the expression is:
[tex]y = 2 + \frac{1}{2}x[/tex]

2⋅10^4-7^3
Answer:
1.9657⋅10^4
Expanded Form:
19657
Step-by-step explanation:
the bold ones are the answers
Answer:
19657
Step-by-step explanation:
Exponentiation: 10 ^ 4 = 10000
Multiple: 2 * the result of step No. 1 = 2 * 10000 = 20000
Exponentiation: 7 ^ 3 = 343
Subtract: the result of step No. 2 - the result of step No. 3 = 20000 - 343 = 19657
I am pretty sure this is correct

Two friends, Sasha and Maria, are growing out their hair. They plan to cut it off at a certain
point and donate it to a charity that makes wigs for people with cancer. Sasha's hair is
already 10 centimeters long and grows at a constant rate of 3 centimeters per month. Maria's
hair is 36 centimeters and growing at a speed of 1 centimeter per month. If the girls get their
hair cut on a certain day, they will have exactly the same length to donate. How long will that
take? How long will their hair be?
In
months, both girls' hair will be
centimeters long,
Answer:
13 months, 49 cms
Explanation:
For Sasha, multiply 3 and 13 together for the growth per month. You should get 39, then add the 10 cm Sasha already has. The sum is 49.
For Maria, multiply 13 and 1 for the growth per month. You should get 13, then add the 36 Maria already has. The sum is also 49.
Hope this helps!

DIBFWhat is the y-intercept of the line represented by -2x + 3y = 12?
F -4
H 4
G 1/4
J 12
Answer:
The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.
Step-by-step explanation:
The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.

Maria has two routes, E and W, she can take when commuting to work. Both routes go through a railroad crossing, and sometimes she needs to stop at the crossing to allow trains to pass. She claims that the proportion of times she needs to stop when taking route E is different from the proportion of times she needs to stop when taking route W. She conducted the following hypothesis test at the significance level of α=0.10.
H0: pE=pW
Ha: pE≠pW
In the hypotheses, pE represents the proportion of times she needs to stop at the crossing when using route E, and pW represents the proportion of times she needs to stop at the crossing when using route W.
All conditions for inference were met, and the resulting p-value was 0.37. Which of the following is the correct decision for the test?
The p -value is less than alpha , and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
The p -value is greater than alpha , and the null hypothesis is not rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is the same for the different routes.
The p -value is greater than alpha , and the null hypothesis is rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
The p -value is greater than alpha , and the null hypothesis is not rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
The p-value is greater than α, and the null hypothesis is rejected. There is convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
Answer:
The p-value is greater than α , and the null hypothesis is not rejected. There is not convincing evidence to support the claim that the proportion of times she needs to stop at the crossing is different for the different routes.
Step-by-step explanation:
The claim is not supported. Since 0.37>0.10, the null hypothesis is not rejected. There is not convincing statistical evidence that the proportion of times she needs to stop at the crossing is different for the different routes.

Continue the pattern by filling in the next 3 terms
-5, -2, 1,
Answer:
4, 7, 10
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 2 - (- 5) = 1 - (- 2) = 3
To obtain a term in the sequence add d = 3 to the previous term, then
a₄ = a₃ + 3 = 1 + 3 = 4
a₅ = a₄ + 3 = 4 + 3 = 7
a₆ = a₅ + 3 = 7 + 3 = 10

Find the area of the composite figure
Step-by-step explanation:
You're only finding half of a circle but since you have 2, it is possible to just do the area of a circle which is [tex]\pi r ^{2} [/tex]
3.5 x 3.5 = 12.25
Because the radius of your circle is 3.5m but there are 2 of them you subtract 7 from 18 which give you 11:
Then you multiply 11 by 7.
= 77
Then add it all together.
[tex]a = (77 + 12.25\pi)m^{2} [/tex]
