Solve | x-1|+5=2 graph the solution (s), if possible.
Answer:
x = -2, 4
Step-by-step explanation:
find the solutions by first subtracting 5 from both sides.
|x-1| = -3
create 2 equations, one with pos. 3 and one with neg. 3.
|x-1| = -3
|x-1| = 3
solve both equations. you can ignore the absolute value signs now.
x = -2
x = 4
those are your two solutions!
I have a polygon 4 angles angle A is 3x angle B is 4x angle C is 2x and angle D is just x please help
Answer:
36 degrees =x
Step-by-step explanation:
If the polygon has 4 angles then it is a quadrilateral and must have 360 degrees. you can see that all angles in that polygon added up are 10x. If 10x=360 then x= 36 degrees, 2x=72 degrees, 3x=108 degrees, 4x=144 degrees
Answer:
36 degrees =x

Wilma estimates that she'll drive about 18,000 miles during the year. The car she wants to purchase gets an
average of 24
miles per gallon, and the average cost per gallon of gas in her neighborhood is $2.72. Locate the error in her calculations,
and select the correction.
Step 1
18,000 miles/year
18.000 miles = 1,500 miles/month
12 months
Step 2
1.500 miles/month
125 gallons/month
12 miles/gallon
Step 3
(125 gallons/month) x ($2.72/gallons) = $340 cost/month
Given parameters:
Distance in a year = 18000miles
Car mileage = 24miles/gallon
Average cost per gallon = $2.72 per gallon
Problem;
Find the error in her calculation;
Step 1
18,000 miles/year
18, 000 miles = 1,500 miles/month -- Since there are 12months in a year
12 months
Step 2
1500 miles/month
Car mileage = 24miles/gallon
Gallons per month; [tex]\frac{1500}{24}[/tex] = 62.5gallons/month
125 gallons/month this is an error and should be 62.5gallons/month
12 miles/gallon should be 24miles per gallon
Step 3
(125 gallons/month) x ($2.72/gallons) = $340 cost/month
Correct
Step 2 is wrong because it uses wrong values.
Answer:
Option 1
Step-by-step explanation:
Wilma made a mistake is step 2. Instead of dividing by 12, she should have divided by 24. She should budget $170 per month for fuel expenses.

Evelyn can run 3 miles in 40 minutes. Which equation can be solved to find m, the number of miles Evelyn can run in 60 minutes? ___1 4 and ____ 4 10 ___3 40 5 _1 m __1 2 and __6 12 ___3 40 5 __ 60 m __ 3 8 and __9 16 ___3 40 5 __ m 1 __ 2 6 and ___3 12 ___3 40 5 ___ m 60
Answer:
Step-by-step explanation:
Let m be the number of miles that evelyn can run in 60 minutes.
If evelyn can run 3 miles in 40 minutes, to calculate the number of miles she can run in 60 minutes, we will apply the equality postulate as shown;
3 miles = 40 minutes
m miles = 60 minutes
Cross multiply
40* m = 3* 60
40m = 180
Divide both sides by 40
40m/40 = 180/40
m = 180/40
m = 4.5 miles
The equation that can be used to find m is 40m = 180 and the value of m is 4.5miles

During her first year of college, Sara put $2000 in the bank to save for a trip to Italy after graduation. The money earned 3% simple annual interest. After 4 years, how much money did she have in the bank for her trip?
a lotStep-by-step explanation:
Answer:
2,240
Step-by-step explanation:
Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Investment of Sara during her 1st year of college = US$ 2,000
Duration of the investment = 4 years
Annual interest rate = 3%
2. Let's find the future value of this investment after 4 years, using the following formula:
FV = PV * (1 + r) ⁿ
PV = Investment of Sara during her 1st year of college = US$ 2,000
number of periods (n) = 4
rate (r) = 3% = 0.03
Replacing with the real values, we have:
FV = 2,000 * (1 + 0.03) ⁴
FV = 2,000 * (1.03) ⁴
FV = 2,000 * 1.12550881
FV = 2,251.02
Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy. Later you round the answer and that gives you 2,240

Step-by-step explanation:
21. 3a + 5b = -27
4a + 10b = -46
how to solve with substitution
Answer:
a = -4 and b = -3
Step-by-step explanation:
Step 1: Solve 3a + 5b = -27 for a
3a + 5b = -27
3a + 5b + -5b = -27 + -5b
(Add -5b go both sides)
3a = -5b- 27
3a = -5b - 27
3 3
(Divide both sides by 3)
a = -5 b - 9
3
Step 2: Substitute -5 b - 9 for a in 4a + 10b = -46
3
4a + 10b = -46
4(-5 b - 9) + 10b = -46
3
10 b - 36 = -46
3
(Simplify both sodes of the equation)
10 b - 36 + 36 = -46 + 36
3
(Add 36 to both sides)
10 b = -10
3
10/3 b = -10
10/3 10/3
(Divide both sides by 10/3)
b = -3
Step 3: Substitute -3 for b in a = -5/3 b - 9
a = -5/3 (-3) - 9
a = -4
(Simplify both sides of the equation)

Identify the values of variables x, y, and z based on the image given of the angles formed by a transversal and parallel lines
Answer:
[tex]x=62\\y=94\\z=94[/tex]
Step-by-step explanation:
Let's start by identifying relevant angle theorems for two parallel lines cut by a transversal.
Alternate Interior Angles Theorem
Two angles that are on different sides of the transversal and inside of the two parallel lines are congruent (=).
Alternate Exterior Angles Theorem
Two angles that are on different sides of the transversal and outside of the two parallel lines are congruent (=).
Same-side Interior Angles Theorem
Two angles that are on the same side of the transversal and inside of the two parallel lines are supplementary (= 180).
Same-side Exterior Angles Theorem
Two angles that are on the same side of the transversal and outside of the two parallel lines are supplementary (=180).
Corresponding Angles Theorem
Two angles on a figure that correspond are congruent (=).
_
Now, let's look at the figure and apply these theorems.
[tex]z[/tex] and [tex]86[/tex] are same-side exterior angles, meaning they're supplementary:
[tex]z+86=180[/tex]
Subtract [tex]86[/tex] from both sides of the equation:
[tex]z=94[/tex]
Now that we know our [tex]z[/tex] value, let's recognize that [tex]z[/tex] ([tex]94[/tex])corresponds to [tex]x+32[/tex], meaning they're congruent:
[tex]x+32=94[/tex]
Subtract [tex]32[/tex] from both sides of the equation:
[tex]x=62[/tex]
Let's find the value of the angle:
[tex](62)+32[/tex]
Add:
[tex]94[/tex]
Since the corresponding angles are of the same value, they're congruent, proving our [tex]x[/tex] & [tex]z[/tex] values correct.
_
Since [tex]y[/tex] and the angle represented by the expression [tex]x+32[/tex] ([tex]94[/tex]°) are alternate-interior angles, they are congruent:
[tex]y=94[/tex]

What is the domain of the function f(x) = x+ 2?
Answer: Choice D) [tex]x \ge -6[/tex]
=========================================================
Explanation:
Taking the square root of a negative number leads to a nonreal result.
So we want the radicand to be 0 or positive
Set the stuff under the square root to be 0 or larger. Solve for x.
[tex]\frac{1}{3}x+2 \ge 0\\\\\frac{1}{3}x \ge 0-2\\\\\frac{1}{3}x \ge -2\\\\x \ge 3(-2)\\\\x \ge -6[/tex]
If x is -6 or larger, then [tex]\frac{1}{3}x+2[/tex] is 0 or larger leading to some real number for f(x).
The inequality sign does not flip because we multiplied both sides by a positive number. The inequality sign only flips when we multiply both sides by a negative number.
