Answer:

x = -20

Step-by-step explanation:

1) Isolate x

-2.5x - 10 = 40

+ 10 + 10

-2.5x = 50

------- ------

-2.5 -2.5

x = -20

Answer:

x=-20

Step-by-step explanation:

-2.5x -10=40

-2.5x -10+10=40+10

-2.5x=50

-2.5x/-2.5=50/-2.5

x=-20

Step-by-step explanation:

9x - 2c = k

    9x = k + 2c

     x  = (k + 2c)/9

Answer: N/A

Step-by-step explanation: you would need K in order to find the value of X,Y,Z

Answer:

If k = 99

then

x = 8

y = 27

z = 64

Step-by-step explanation:

You have to use a different number for each letter so you can but in any combination the answer just has to make sense as in you added up x, y, and z to get k.

Answer:

h= 14

Step-by-step explanation:

7h-5(3h-8)= -72  PEDMAS Parenthesis first

7h-15h+40= -72 combine like terms

-8h+40= -72  subtract 40 from both sides

-8h=-112  divide by -8

h=14

The required simplified solution of the given expression is h = 4.

Given that,
A number of instruction has been added in the question, guiding the solution of the given expression.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
7h-5(3h-8) = -72

Simplify,
7h -5×3h - 5× -8 = -72
7h -15h + 40 = -72
8h = -72 + 40
-8h = -32
h = 4

Thus, the required simplified solution of the given expression is h = 4.

Answer:

I think the answer is A.

Can you make me brainlest plz? :)

Answer:

x=-3

Step-by-step explanation:

Solve for x:

5x+2=4x−1

Move all terms containing x to the left side of the equation.

x+2=−1

Move all terms not containing x to the right side of the equation.

x=−3

Answer:The slope of a line measures the steepness of the line. Most of you are probably familiar with associating slope with "rise over run". Rise means how many units you move up or down from point to point. Run means how far left or right you move from point to point. On the graph, that would mean a change of x values.

Answer:

[tex]\frac{5}{8}[/tex]

Step-by-step explanation:

I hope this helps!

Answer:

5/8 or 0.625

Step-by-step explanation:

multiply the numerator so that equals 5

multiply the denominator so that equals 8

the fraction answer is 5/8

the decimal answer is 0.625; this is because when you divide 5 and 8, you get 0.625

if you need more explanation, 5/1 times 1/8

just multiply across the top and bottom to get your answer

Answer:

No answer.

Step-by-step explanation:

- 8m - 12 > -5m + 40 - 3m + 21

combine terms

-8m - 12 > -8m +61

add 8m to both sides

-12 > 61

negative 12 is not greater than 61

[tex] \because \angle JKM [/tex] is the exterior angle of [tex] \triangle KLM [/tex]

[tex] \therefore [/tex] by remote interior angle theorem of a triangle, we have:

[tex] m\angle L + m\angle M = m\angle JKL \\\\

(18z + 3)\degree + (5z - 3)\degree = 161\degree \\\\

(18z + 3+5z - 3)\degree = 161\degree \\\\

(23z)\degree = 161\degree \\\\

23z = 161\\\\

z = \frac{161}{23} \\\\

\huge \red {\boxed {z = 7}} \\\\

\because \measuredangle L = (18z +3)\degree \\\\

Answer:

A

Step-by-step explanation:

(0, 2) is the y intercept of the given graph, option B is correct.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The line is passing through the points (3, 0) and (0,2)

We have to find the slope

m=2/-3

=-2/3

Now let us find y intercept

0= -2/3(3) +b

b=2

Hence, (0, 2) is the y intercept of the given graph, option B is correct.

Answer:

After solving the compound inequality [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex] we get [tex]\mathbf{x>5 \ or \ x<-4}[/tex]

Option B is correct.

Step-by-step explanation:

We are given compound inequality: [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex]

We will first solve the inequalities to find the value of x, then will draw the graph.

[tex]1.5x-1>6.5 \ or \ 7x+3<-25\\1.5x-1+1>6.5+1 \ or \ 7x+3-3<-25-3\\1.5x>7.5 \ or \ 7x<-28\\x>\frac{7.5}{1.5} \ or \ x<\frac{-28}{7}\\x>5 \ or \ x< -4[/tex]

So, after solving the compound inequality [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex] we get [tex]\mathbf{x>5 \ or \ x<-4}[/tex]

Now, the number line will be as shown in figure.

Answer:

We also know that the sum of the measures of arcs AD, AB, CD, and BC must be 360 degrees, because there are 360 degrees in a full circle. Because AD = 2AB, we can substitute 2AB for AD. This means the measure of arc AB is 70 degrees, and the measure of arc AD is 2(70) = 140 degrees.
