Answer:
R=-12
Step-by-step explanation:
6(1 + 3R) = 2(10R - 9) -4R
Distribute 6 through the parentheses
6+18R=2(10R-9)-4R
Distribute 2 through the parentheses
6+18R=20R-18-4R
Collect like terms
6+18R=16R-18
Move the variable to the left-hand side and change its sign
6+18R-16R=-18
Move the constant to the right-hand side and change its sign
18R-16R=-18-6
Collect like terms
2R=-18-6
Calculate the difference
2R=-24
Divide both sides of the equation by 2
R=-12
if you'd make me brainliest that'd be great, if not its ok as well! I hope this helped!!!
Jerry thinks that x < 4 is a solution to the following inequality: 2x + 10 < 4x - 20
Is Jerry right? Justify your response.
plss guys help me i only have 6 minutes left
Answer:
x>15
Step-by-step explanation:
Given the inequality: 2x + 10 < 4x - 20
Collect like terms
2x-4x<-20-10
-2x<-30
x > -30/-2
x>15
Hence the solution is x>15
5. What is the solution to the equation -2.5(x-4)=-3x+4?
Answer:
x = -12
Step-by-step explanation:
-2.5(x-4)=-3x+4
Distribute
-2.5x +10 = -3x +4
Add 3x to each side
-2.5x+10 +3x = -3x+4+3x
.5x +10 = 4
Subtract 10 from each side
.5x+10-10=4-10
.5x = -6
Divide by .5
.5x/.5 = -6/.5
x = -12
Answer: -12
Step-by-step explanation:
-(25/10)*(x-4)-(-3*x+4)=0
(0 - (5/2— • (x - 4))) - (4 - 3x) = 0
-5 • (x-4) - ((4-3x) • 2)/2 = x + 12/2
x+12 /2 • 2 = 0 • 2
-12

Answer:
F; A translation of 6 up and 4 left and a reflection across the x-axis
Step-by-step explanation:
Here, we want to perform the translation that would move S to S’
to do this, we can have a subtraction
For 1 to move to -3 on the x-axis;
it means there is a leftward shift of upto 4 units
For -8 to turn to 2;
this is positive; there is a vertical upward translation of upto 10 units on the y-axis
This option is not directly available; thus we have to factor the reflection
if we reflect on the x-axis, the y-axis value becomes negated; if we reflect on the y-axis, the x-value becomes negated
The correct answer is thus;
A translation of 6 up and 4 left, followed by a reflection across the x-axis
If y= 4x, calculate the value of y when x= 12
Answer:
y = 48
Step-by-step explanation:
y = 4 * 12
y = 48
Joe and Sam shared a cheesecake cut into 12 pieces Joe ate three pieces and Sam ate five pieces what fat Shaun of the cheesecake did they eat in all show how you find your answer
Answer:
The fraction ate is 2/3
Step-by-step explanation:
Here, we want to get the fraction of the total ate
From the question, Joe ate 3 out of 12 pieces;
That would be 3/12
same ate 5 out of 12, that will be 5/12
So the fraction ate will be;
3/12 + 5/12 = 8/12 = 2/3

What is the slope of -1/2x+2y=7
Answer: 1/4
Step-by-step explanation:
First, we have to rearrange the given equation so that it results in a y=mx+b equation. To do this we can add -1/2x on both sides to remove it from the left side.
(+1/2x)-1/2x + 2y = 7(+1/2x)
2y = 1/2x +7
Now we can divide by 2 on both sides to isolate the y.
(2y)/2 = (1/2x +7)/2
y = 1/4x + 3.5
The slope is 1/4 :)

Parentheses tell you to multiply first.
Parentheses tell you to do the operation with the largest numbers.
Parentheses tell you to add first.
Parentheses tell you what operation to do first.
Answer:
The Parenthesis tells you what operation to do first.
Step-by-step explanation:
Why? Because you have to get rid of the Parenthesis before getting rid of anything else in the problem.

13. 12/16
14. 35/15
15. 20/36
18.45/24
Step-by-step explanation: 12. 4x5=20 so 1x5=5 so its 5/20
13. 3x4=12 so 4x4=16 so its 12/16
14. 7x5= 35 so 3x5=15 so its 35/15
15. 9x4=36 so 5x4=20 so its 20/36
18. 15x3=45 so 8x3=24 so its 45/24
