Answer:
r= -3
Step-by-step explanation:
-3 r + 3(r-2) = -2(r+6)
-3r+3r-6= -2r-12
-6= -2r-12
2r=6-12
2r= -6
r= -3

Cassidy wrote the linear equation y = 5 x + 4. Then, she wrote the equation of the line that is parallel to y = 5 x + 4 and that passes through (8,–2). If her new equation is in the form y = 5 x + b, what is the value of b?
Answer:
b=−5x+y
Step-by-step explanation:
Let's solve for b.
y=5x+b
Step 1: Flip the equation.
b+5x=y
Step 2: Add -5x to both sides.
b+5x+−5x=y+−5x
b=−5x+y

why do you multiply by 4/3 when you have 1/2x+2=3/4y when solving for y?
Step-by-step explanation:
You multiply by 4/3 because you are essentially "dividing" both sides by 4/3. You have to take the reciprocal of 3/4 which is 4/3 in order to cancel out the 3/4 because 4/3 x 3/4 will be 1. So the problem will look like this:
(1/2)x + 2 = (3/4)y
4/3[(1/2)x + 2] = 4/3 x 3/4y
4/3[(1/2)x + 2] = y
4/6 x + 8/3 = y
y = 2/3(x) + 8/3
And then from here, if they gave a value for x and y, you can solve for the 2 variables.

3x+2(5x-3)=7
with steps
Answer: x=1
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*x+2*(5*x-3)-(7)=0
3x + 2 • (5x - 3)) - 7 = 0
Pull out like factors :
13x - 13 = 13 • (x - 1)
13 = 0
A a non-zero constant never equals zero.
Solve : x-1 = 0
Add 1 to both sides of the equation :
x = 1

Alonzo earns 8% commission on vacuum cleaner sales. This past month, Alonzo sold 70 units at $150.00 each. How much did Alonzo make in commissions for the past month?
Answer:
$840
Step-by-step explanation:
price of 1 vacuum cleaner = $150
total no . of vacuum cleaner sole = 70
thus,
price of 70 vacuum cleaner sold = 70*price of 1 vacuum cleaner
price of 70 vacuum cleaner sold = 70*$150 = $10,500
commission of Alonzo = 8% of total vacuum cleaner sold
commission of Alonzo = 8% of $10,500
commission of Alonzo = 8 /100 * $10,500 = $840
Thus, Alonzo made $840 in past month
Help me please i’m dying and i’m just dying help
Answer:
70
Step-by-step explanation:
verticle angles are congruent (the same) so if 1 is 110 than 4 is 110. also same side interior angles are supplementary (equal to 180) meaning 6 is 70. If verticle angles are congreunt then 7 also equals 70

It takes 66 pounds of seed to completely plant a 7-acre field.
How many acres can be planted per pound of seed?
acres per pound
Answer:
Approximately 0.11 acres can be planted with one pound of seed
Step-by-step explanation:
You use the rule of 3
66 pounds / 7 acres = ? pounds / 1 acre
? = 66 x 1 ÷ 7
? = 66 ÷ 7
? ≈ 9.23 pounds / acre
Now you know how many pounds you have for 1 acre. You reuse the formula from before
9.23 pounds / 1 acre = 1 pound/ ? acres
? = 1x1 ÷ 9.23
? = 1 ÷ 9.23
? = 0.11 acres/pound
Verify the answer:
0.11 x 9.23 ≈ 9.33, which is approximately 1 pound
Answer:
90 pounds per acre

what is 40 times 8 minus 10 to the power of 2
Answer:
220
Step-by-step explanation:
40 x 8 = 320
[tex]10^{2}[/tex] = 100
320- 100 = 220
Hope that helps and have a great day!
Answer:
220
Step-by-step explanation:
Rewritten in numerical terms, the problem is:
40 * 8 - 10^2
Remember PEMDAS:
10^2 = 100
40*8 = 320
320 - 100 = 220
220
suppose you take the small prism and stack it on top of the larger prism. what will be the volume of the composite figure?
Please help! I need help on the whole worksheet
In this figure ∠7 and ∠3 are alternate interior angles . Alternate interior angles in two parallel lines with a transversal will always be equal . Since ∠7 is congruent to ∠3 , we can say that line m and line n are parallel lines .
Therefore :-
The lines are parallel because the alternate interior angles in them are congruent .
Solution (2) :-Given :-
m∠3 = ( 15x + 22 )°
Then , m∠3 will be equal to :-
x = 8
= 15 × 8 + 22
= 120 + 22
m∠3 = 142°
m∠1 = ( 19x - 10 )°
= 19 × 8 - 10
= 152 - 10
m∠1 = 142°
angle 1 and angle 3 are corresponding angles , which means their value will be equal if they are present on two parallel lines with a transversal . As their values are equal we can say that line m and line n are parallel .
Therefore :-
Yes , the lines are parallel because the corresponding angles in them are equal .
Solution (3) :-∠7 and ∠6 are interior angles on the same side of transversal , which means their angle su, will be equal to 180° . But since their values are equal these two lines are not parallel .
Therefore :-
∠7 and ∠6 are interior angles on the same side of transversal , so their sum will be equal to 180° . But since that is not the case in the lines shown above , those lines are not parallel lines .
Solution (4) :-Given :-
m∠2 = ( 5x + 3 )°
x = 14
= 5 × 14 + 3
= 60 + 3
= 63°
m∠3 = ( 8x - 5 )°
= 8 × 14 - 5
= 112 - 5
= 107°
We know that the sum of angle 2 and angle 3 will be equal to 180° if they are on two parallel lines as they are interior angles on the same side of transversal .
As :-
∠2 + ∠3 ≠ 180°
63° + 107° is not equal to 180° ,
Therefore :-
These lines are not parallel as the sum of their interior angles on the same side of transversal is not equal to 180°.
Solution (5) :-Given :-
m∠8 = ( 6x - 1 )°
x = 9
= 6 × 9 - 1
= 54 - 1
= 53°
m∠4 = ( 5x + 3 )°
= 5 × 9 + 3
= 45 + 3
= 48°
angle 8 and angle 2 are vertically opposite angles , which means m∠8 = m∠2 .
m∠2 = 53°
As ∠2 and ∠4 are corresponding angles their value will be equal , if they are on parallel lines .
Since angle 2 , angle 8 and angle 4 are not equal these lines are not parallel lines .
Therefore :-
The lines are not parallel as their corresponding angles are not equal .
Solution (6) :-Angle 5 and angle 7 are corresponding angles they will be congruent when on parallel lines .
As , m∠5 ≅ m∠7 these lines are parallel .
Therefore :-
These lines are parallel lines as their corresponding angles are equal .
Solution (7) :-Angle 1 and angle 7 are vertically opposite angles , which means their angle measure will be equal . As angle 7 and angle 5 are corresponding angles their angle measure will also be equal .
Since m∠5 ≅ m∠7 , these lines are parallel .
Therefore :-
These lines are parallel lines as their corresponding angles are equal .
Solution (8) :-Here , the value of x is the same .
Which means :-
m∠2 = x + 15° is greater than m∠6 = x + 10°
Angle 2 and angle 6 are alternate interior angles , their values should be equal . But since their values are not equal , the lines on which they reside are not parallel .
Therefore :-
These lines are not parallel as their alternate interior angles are not equal .
Solution (9) :-It is given that angle 1 and angle 3 are supplementary angles . It is also clear that angle 1 and angle 2 are a linear pair , which means their angle sum will be equal to 180° . Also , angle 3 and angle 2 should be equal since they are the supplement of the same angle . Angle 2 and angle 3 are also corresponding angles . Since corresponding angles in two lines with a transversal will be equal and in these two lines the corresponding angles are equal , these lines are parallel lines.
Therefore , JK // HI as their corresponding angles are equal .
