88 is a solution to (1/8) x =11 because if x = 88 then the equation (1/8) x = 11 is true.
Answers
Answer:
True
Step-by-step explanation:
To check to see if the statement given is true we need to substitute x with 88 and solve.
[tex](1/8)x=11[/tex]
Substitute 'x' for 88.
[tex](1/8)88=11\\\\\boxed{11=11}[/tex]
88 is a solution to the equation, therefore the statement is true.

-6p-3=9 what does p equal
Answers
Answer:
-2
Explanation:
-6 x -2 = 12
12 - 3 = 9
Answer:
p=-2
Step-by-step explanation:
Move the -3 to the other side by adding 3 on both sides:
-6p-3+3=9+3
The equation now looks like this:
-6p=12
Divide -6 on both sides:
-6p/-6=12/-6
The equation now looks like this:
p=-2 which is the answer

Solve the system by substitution.
y = 5x
y = 9x + 4
Answers
Answer:
(-1, -5)
Step-by-step explanation:
[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]
1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)

Identify whether the expressions are equivalent or not equivalent: 7y – 15 + 2y and 9y - 15
Answers
Answer:
Yes, the two expressions are equivalent
The given expression 7y - 15 + 2y and 9y - 15 are equivalent.
What is equivalent expression?
Two algebraic expressions are said to be equivalent if their values obtained by substituting the values of the variables are same, even they look different.
According to the given question.
We have two expressions
[tex]7y - 15 + 2y ...(i)[/tex]
And, [tex]9y - 15 ...(ii)[/tex]
The expression (i) can be written as
[tex]7y - 15 + 2y[/tex]
[tex]=(7y + 2y)-15[/tex] (adding the like terms)
[tex]= 9y -15[/tex]
Hence, the given expression 7y - 15 + 2y and 9y - 15 are equivalent.

Graph the line with a slope of 2/3 that contains the point (−3,−5)
Answers
Answer:
Step-by-step explanation:
So for the given information, it would be easiest to use slope-intercept form, which is y=mx + b, where m is the slope and b is the y-intercept.
We can plug in 2/3 for the slope, because we are given that.
y=2/3x + b.
To find the y-intercept, plug in the given point for x and y and solve for b.
-5 = 2/3 · (-3) + b
-5 = -2 + b
b = -3
So now we have the complete equation of the line.
y = 2/3x -3
Now to graphing.
We can put the y-intercept, (0, -3), and the given point, (-3, -5) on a graph.
Complete the table below to find solutions to the linear equation 3x+y=−21.

PLEASE HELPPPP!!! Find the measure of angle A
Answers
========================================================
Explanation:
The three angles of this triangle are
20x9026x-2The square angle marker represents 90 degrees. It's also referred to as "a right angle".
As a rule, the three angles of any triangle always add to 180. Let's use this fact to solve for x
(angle1)+(angle2)+(angle3) = 180
(20x)+(90)+(26x-2) = 180
(20x+26x) + (90-2) = 180
46x+88 = 180
46x = 180 - 88 .... subtract 88 from both sides
46x = 92
x = 92/46 ........ divide both sides by 46
x = 2
Now that we know what x is, we can find angle A
angle A = 20x = 20*2 = 40 degrees
-------------
As extra info, we could also find the other angle with this x value
26x - 2 = 26*2 - 2 = 52 - 2 = 50 degrees
The three angles of the triangle are: 40, 50, 90 which add to 40+50+90 = 180. This helps confirm our answer.

Rewrite each angle in radian measure as a multiple of π· 30°
Answers
Answer:
[tex]\frac{\pi}{6}[/tex] radian
Step-by-step explanation:
We are given that an angle in degrees
[tex]\theta=30^{\circ}[/tex]
We have to find the angle in radian measure as a multiple of π
To find the value of 30 degree in radian we will use the radian measure formula
We know that
Radian measure=[tex]\frac{\pi}{180}\times degree\;measure[/tex]
Using the formula
Radian measure of 30 degree=[tex]\frac{\pi}{180}\times 30[/tex]
Radian measure of 30 degree=[tex]\frac{\pi}{6}[/tex] radian
Hence, the radian measure of 30 degree is given by
