Solve and show your work: |4x − 1| = 13
PLEASE HELP ME
Answer: x=7/2, x=-3
Step-by-step explanation:
First lets do look at it without the absolute value marks
4x-1=13
4x=14
x=7/2
Now lets do the same but assume 13 is negative,
4x-1=-13
4x=-12
x=-3

g(a) = 4a - 5; Find a when g(a)=-37
Answer:
a = -8
Step-by-step explanation:
g(a) = -37
g(a) = 4a - 5
g(a) = 4a - 5
-37 = 4a - 5
-37 + 5 = 4a
-32 = 4a
a = -32/4
a = -8
A triangle has one angle that measure 75% and one that measure 19% what is the measure of the third angle
Answer:
86%
Step-by-step explanation:
angles in the triangle add up to 180
so we add 75% and 19%
to get 94%
then we subtract 180 by 94%
to get 86%
Which group of numbers could be the measures of the sides of a right
triangle?
At this weekend's football game, 12 out of the first 48 people who enter the field were not wearing hats. If this sample is representative of 200 people attending the game, about how many of them will probably not be wearing hats?
A. 17 people
B. 36 people
C. 50 people
D. 80 people
Answer:
the answer would be C. 50
Step-by-step explanation:
because 200÷48 is 4.16 and 4.16×12 is 49.92 and that rounds to 50 or you could do it easier like the one up about

What is the slope of y = -x + 5
Answer:
-1
Step-by-step explanation:
x = the slope. Since it says -x we know that it'd be -1.

1. Rewrite in slope-intercept form. *
- 7x + 2y = 8
Answer:
y = [tex]\frac{7}{2}[/tex] x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 7x + 2y = 8 ( add 7x to both sides )
2y = 7x + 8 ( divide all 3 terms by 2 )
y = [tex]\frac{7}{2}[/tex] x + 4 ← in slope- intercept form
If you have $32 and you want to see how many bulbs of elephant garlic you want to buy if four bulbs costs $8 , you first need to see how many $8 can fit into $32 . Thus, divide 32 by 8 . Now that you know $8 can fit into $32 four times, multiply 4 by 4bulbs , since there are four bulbs per $8 .

What's the question it awnsers itself?
Step-by-step explanation:
A sprinkler can water between 1 and 130 square yards of a lawn. The length L in inches of rotating pipe needed to water A square yards is given by the function L=119.75 square root of A. How much area can be watered if the length of the pipe is 600, 900, or 1,000 inches long?
Answer:
[tex]25.1\ \text{inches}^2[/tex]
[tex]56.5\ \text{inches}^2[/tex]
[tex]69.7\ \text{inches}^2[/tex]
Step-by-step explanation:
The length of the pipe is given by the function
[tex]L=119.75\sqrt{A}[/tex]
where A is the area
[tex]A=(\dfrac{L}{119.75})^2[/tex]
For [tex]L=600\ \text{in}[/tex]
[tex]A=(\dfrac{600}{119.75})^2\\\Rightarrow A=25.1\ \text{inches}^2[/tex]
Area watered when L = 600 inches is [tex]25.1\ \text{inches}^2[/tex]
For [tex]L=900\ \text{in}[/tex]
[tex]A=(\dfrac{900}{119.75})^2\\\Rightarrow A=56.5\ \text{inches}^2[/tex]
Area watered when L = 900 inches is [tex]56.5\ \text{inches}^2[/tex]
For [tex]L=1000\ \text{in}[/tex]
[tex]A=(\dfrac{1000}{119.75})^2\\\Rightarrow A=69.7\ \text{inches}^2[/tex]
Area watered when L = 1000 inches is [tex]69.7\ \text{inches}^2[/tex]

Aaron has $150 at the start of the week. By the end of the week, he has 30% more money. How much
total money does he have at the end of the week? Show work, using any method.
Answer:
$195
Step-by-step explanation:
To solve a percent problem, you can use the equation: part %
------- = -----
whole 100
You want to find 30 percent, so the % would be 30. You also want to find 30% of 150, so the whole would be 150 and the part would be x. Cross multiply to get 100x = 4500. Then, divide 4,500 by 100. The equation should look like this: x = 45. Add 45 to $150 to get $195. So Aaron has $195 at the end of the week.

Answer:
5.82 x 10^6
Step-by-step explanation:
Answer:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

factorise 3abc+6a²b pleaze with step too
Answer:
3ab(c+2a)
Step-by-step explanation:
Given data
3abc+6a²b
we can see that 3, a, and b are common between the two terms
so let us factor them out
3ab(c+2a)
Hence the factored form is
3ab(c+2a)
What is the slope of the line that passes through the points (-10, -8) and
(-8, -16)? Write your answer in simplest form.
Answer:
-4
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(-16 + 8) / (-8 + 10)
-8 / 2
= -4
So, the slope is -4

Divide 2m in the ratio 9-1
Answer:
Step-by-step explanation:
First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.
To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.
