Answer:
The first step would be to add twelve to both sides
Step-by-step explanation:
Answer:
add 12 to both sides
Step-by-step explanation:
What we want to do, is to isolate the variable and the numbers on different sides.
if we divide 5x and -20 by 5, what about -12? It's part of the equation too.
If we add 20 to both sides, the numbers and the variable are on the same side, so we'll need to subtract it back off to isolate both.
If we multiply 12 by (what was there) it won't be isolating the variable or numbers. We'll just be increasing the value of the terms already there.
However, if we add 12 to both sides, we'll be isolating both the variable AND the numbers onto different sides.
therefore, add 12 to both sides.
Hope this helps!
Substitute teachers with Lexington School District get paid by the day, although subs with teaching credentials earn a different amount than subs without credentials. Yesterday, 3 non-credentialed subs and 2 credentialed subs taught in the district. That cost the district $368. Today, 11 non-credentialed subs and 7 credentialed subs taught, receiving $1,316 from the district. How much do subs get paid?
please help, choose the correct equation

(5x - 15) - (2x + 5) = 3x - 20
(2x + 5) - (5x - 15) = - 3x + 20
The sum is ___
Step 1: Simplify both sides of the equation.
5x−15−(2x+5)=3x−20
5x−15+−1(2x+5)=3x−20(Distribute the Negative Sign)
5x+−15+−1(2x)+(−1)(5)=3x−20
5x+−15+−2x+−5=3x−20
5x+−15+−2x+−5=3x+−20
(5x+−2x)+(−15+−5)=3x−20(Combine Like Terms)
3x+−20=3x−20
3x−20=3x−20
Step 2: Subtract 3x from both sides.
3x−20−3x=3x−20−3x
−20=−20
Step 3: Add 20 to both sides.
−20+20=−20+20
0=0

Robert gets a loan from his bank.
He agrees to borrow £6000 at a fixed annual simple interest rate of 7%.
He also agrees to pay the loan back over a 10 year period.
How much money in total would he have paid back in 10 years?
Answer:
£10,200
Step-by-step explanation:
Simple interest = principal × rate × time
Principal = £6000
Rate = 7% = 0.07
Time = 10 years
Simple interest = principal × rate × time
= £6000 × 0.07 × 10
= £4,200
Total = simple interest + principal
= £4,200 + £6,000
= £10,200
He would have to pay back a total of £10,200 in 10 years

Select the lines that represent functions.
Answer:
All of them except the squiggly one and the vertical one
Step-by-step explanation:
The rest are functions, two of them are lines, and the curved swoop is a parabola, which is also a function
Function is a set of relation without same or repetitive domain. Because we are checking if the following graphs are function or not. It is easier to do line test.
How to check if the graphs are function.
Draw a vertical line.If the line passes or intercepts the graph only one point. The graph is function.If the line passes or intercepts the graph more than a point. The graph is not a function.Overall, the graphs that are not function are the vertical line and the vertical curve graph.
AnswerA horizontal lineA line with slope or steepnessParabola aka curve graph (The graph is not a line. The question asks for lines which represent functions. I am not sure if they want all graphs that are function or just lines that are functions. A Parabola graph is also a function but not a line graph.)Feel free to ask if you are confused.

One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cylinder. If the first cylinder’s volume is 216 Centimeters cubed, what is the correct equation and value of x, the volume of the second cylinder?
StartFraction 7 over 8 EndFraction x + 8 = 216; x = 182 centimeters cubed
StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 196 centimeters cubed
StartFraction 7 over 8 EndFraction x + 8 = 216; x = 238 centimeters cubed
StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 256 centimeters cubed

Solve the inequality 24 + 4x ≥ 100
Answer:
x ≥ 19
General Formulas and Concepts:

Step 1: Define
24 + 4x ≥ 100
Step 2: Solve for x
Subtract 24 on both sides: 4x ≥ 76Divide 4 on both sides: x ≥ 19Here we see that any value x greater than or equal to 19 would work as a solution to the inequality.

Step-by-step explanation:
Answer:
Point Form: (1,−3/4)
Equation Form: x=1, y= −3/4
Step-by-step explanation:
Solve for x in the first equation.
x=2+4y/3
5x+8y=−1
Replace all occurrences of x with 2+4y/3 in each equation.
10+44y/3=−1
x=2+4y/3
Solve for y in the first equation.
y=−3/4
x=2+4y/3
Replace all occurrences of y with −3/4 in each equation.
x=1
y=−3/4
Could someone please help me with this?
Answer:
Both are 38°
Step-by-step explanation:
Is in attachment...
I'm horrible at this please help:((((
Step-by-step explanation:
You can insert different values of x to find y
For example:
x = 4
Plug in x into the equation
y = -1/2(4) + 5
y = -2 + 5
y = 3
So your point will be (4, 3)
If you do 1 more like this, you can draw a line between them. Or you can use Desmos to graph the line.
Hope this helped you!!
At what point do the lines y= 2x + 3 and y = 5x - 9 intersect?
Answer:
(4,11)
Step-by-step explanation:
y=2x+3
y=5x-9
the first equation is equal to the second equation so
2x+3=5x-9
put like terms together
2x-5x= -9-3
-3x= -12
divide both sides by -3
.•.x=4
now, use the value of x to find the value of y like this:
y=2x+3 (x=4)
y=2(4)+3
y=8+3
y=11
therefore, the two lines intersect at the point (4,11)
