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!

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
The correct verbal expression for 8n is "the product of 8 and n". Therefore, option H is the correct choice.

Option F "n more than 8" would be written as "n + 8".

Option G "the quotient of 8 and n" would be written as "8/n".

Option J "8 increased by n" would be written as "8 + n".

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:

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

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

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)

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.

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]

Answer:

[tex]x=\frac{y}{3b-7}[/tex]

Step-by-step explanation:

Rewrite the equation as [tex]3bx-7x=y[/tex].

Factor  x  out of  3 b x

[tex]x(3b)-7x=y[/tex]

Factor [tex]x[/tex] out of [tex]x(3b)+x*-7[/tex]

[tex]x(3b-7)=y[/tex]

Divide each term by [tex]3b-7[/tex]   and simplify.

Divide each term in [tex]x(3b-7)=y[/tex] by [tex]3b-7[/tex].

[tex]\frac{x(3b-7) }{3b-7} =\frac{y}{3b-7}[/tex]

Cancel the common factor of [tex]3b-7[/tex]

Step-by-step explanation:

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.
