Answer 1

Answer:

X= 4

Step-by-step explanation:

Answer 2

Answer:

x=4

Step-by-step explanation:

-7x - 8 = -10x + 4

-7x - 8 + 10x = 4 ( add 10x to the left side and subtract 10x from the right)

3x - 8 = 4 ( add -7x and 10x to get 3x)

3x = 4 + 8 ( add 8 to the right and subtract 8 from the left)

3x = 12 ( add 4 and 8 to get 12 )

[tex]\frac{3x}{3}[/tex] = [tex]\frac{12}{3}[/tex] ( divide both sides by 3 )

x = 4

The answer is x =4

Deborah decided to mow lawns to earn the $280
she needs for a school orchestra trip. If she earns
$18 per lawn, what is the minimum number of
lawns she needs to mow to earn the money for the
trip?
A. 15
B. 16
C. 18
D. 20

Answers

Answer:

16

Step-by-step explanation:

Because 15 times 18 is 270. But 18 times 16 is 288.

So she already achieved the money earned with the smallest amount over of what she wanted.

Answer:

135 degree angle

Step-by-step explanation:

1. Triangle Sum Theorem: Calculate the angles of the triangle.

Remember that the sum of all the angles of ANY triangle is 180 degrees. To find the missing angle of the triangle all we need to do is subtract 180 degrees with 69 and 66 to get the missing angle of the triangle (45 degrees)

2. Angle Sum Theorem?: Note: the degrees of a straight line is 180 degrees

We now know that the missing angle of the triangle is 45 degrees. We also know that the degree of a straight line will always equal to 180 degrees. We can find angle x by doing 180 - 45, similarly to when we found the missing angle.

Answer: 123 degree angle

Write the equation of the line that passes through (1,8) and (3, 3). Write it in slope-intercept form.

Answers

Answer:

y = - [tex]\frac{5}{2}[/tex] x + [tex]\frac{21}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 8) and (x₂, y₂ ) = (3, 3)

m = [tex]\frac{3-8}{3-1}[/tex] = - [tex]\frac{5}{2}[/tex] , thus

y = - [tex]\frac{5}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 8), then

8 = - [tex]\frac{5}{2}[/tex] + c ⇒ c = 8 + [tex]\frac{5}{2}[/tex] = [tex]\frac{21}{2}[/tex]

y = - [tex]\frac{5}{2}[/tex] x + [tex]\frac{21}{2}[/tex] ← equation of line

Answers

Answer:

Infinite Amount of Solutions

Step-by-step explanation:

Step 1: Write equation

3(4x + 6) = 2(6x + 9)

Step 2: Solve for x

Distribute: 12x + 18 = 12x + 18

We see here that both sides of the equation are the same. Therefore, x is equal to infinite amount of solutions.

Another way to think about it is that the 2 lines are the same line. If both lines are the same, then they have infinite amount of solutions.

For which inequality is x = 5 a solution?
A. X<2
B. X>9
C. X<18
D. X>42

Answers

Answer: The answer is C.

Step-by-step explanation:

Since x = 5, we will substitute.

A- 5<2. Five is less than two.

B- 5>9. Five is greater than nine.

C- 5<18. Five is less than eighteen.

D- 5>42. Five is greater than forty-two.

The only logical answer is C, since five IS less than eighteen.

The inequality expression that gives the correct solution of x = 5 is x < 18

Inequalities are expressions not separated by an equal sign.

The inequality signs are <, >, ≤ and ≥

< means less than

> means greater than;

≤ means less than and equal to

≥ means greater than and equal to

From the question, we need to find which of the inequalities gives a solution of x = 5

For the inequality x< 2 (x is less than 2). Since 5 is greater than 2, hence this inequality expression is wrong.

For the inequality x>9 (x is greater than 9). Since 5 is less than 9, hence this inequality expression is also wrong.

For the inequality x < 18 (x is less than 18). Since 5 < 18, hence, this gives the correct inequality expression

The inequality expression that gives the correct solution of x = 5 is x < 18

Kurt and Maria’s high school is having a newspaper drive.The goal is to collect 3,585 pounds of newspapers. So far, 21% of the goal has been reached.

Kurt estimated the number of pounds of newspapers collected by finding 10% of 3,600 and then multiplying the result by 2.

Maria estimated the number of pounds of newspapers collected by finding One-fifth of 3,600.

Who is right, and why?

Neither Kurt nor Maria is right, because 3,500 should be used instead of 3,600.
Kurt is right, because finding One-fifth of 3,600 is not a good way to approximate 21% of 3,585.
Maria is right, because finding 10% of 3,600 and multiplying the result by 2 is not a good way to approximate 21% of 3,585.
Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding One-fifth of 3,600.​
