Answer:
y=4
Step-by-step explanation:
Let's solve your equation step-by-step.
5y−14=2y−2
Step 1: Subtract 2y from both sides.
5y−14−2y=2y−2−2y
3y−14=−2
Step 2: Add 14 to both sides.
3y−14+14=−2+14
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
Answer:
5y + -14 = 2y + -2
-14 + 5y = 2y + -2
-14 + 5y = -2 + 2y
-14 + 5y = -2 + 2y
-14 + 5y + -2y = -2 + 2y + -2y
5y + -2y = 3y
-14 + 3y = -2 + 2y + -2y
2y + -2y = 0
-14 + 3y = -2 + 0
-14 + 3y = -2
-14 + 14 + 3y = -2 + 14
-14 + 14 = 0
0 + 3y = -2 + 14
3y = -2 + 14
-2 + 14 = 12
3y = 12
y = 4

2. Which expression is equivalent to

3. Matt and his friends paid $30 for 4 sandwiches and 4 bottles of water. Each sandwich cost the same amount. The bottles of water cost $2 each. how much does the sandwich cost
Answer:
1. 3x + 2
2. 0.25x - 6.5
3. $5.50 per sandwich
Step-by-step explanation:
1.
6x + 1 - (3x - 1)
PEMDAS says solve everything in the parentheses first
There is nothing left to simplify within the parentheses.
Since there's also no exponents, multiplication, or division, let's combine like terms starting from left to right
6x - 3x + 1 + 1
Negative + Negative = Positive, hence why it became 1 + 1
3x + 2
2.
(3x - 1) - 2.75 (x + 2)
PEMDAS says to do multiplication next (since parentheses are fully simplified and there are no exponents)
(3x - 1) - 2.75x - 5.5
Negative + Positive = Negative, hence why it became -5.5
3x - 1 - 2.75x - 5.5
Combine like terms
3x - 2.75x - 1 - 5.5
0.25x - 6.5
3.
Set up an equation:
Variable x = cost of sandwiches
4x + 4(2) = 30
4x + 8 = 30
Subtract 8 from both sides to isolate the variable
4x + 8 - 8 = 30 - 8
4x = 22
Divide both sides by 4
4x ÷ 4 = 22 ÷ 4
x = 5.5
$5.50 per sandwich

Which expression is equivalent to 5(4x + 12) + 3x + 2?
Answer: 23x + 62
Step-by-step explanation: First multiply 5 and 4x which you should get 20x, then multiply 5 and 12 which is 60 and add it to your expressions which looks like 20x + 60 + 3x + 2. Then your going to add 60 and 2 and get 62, lastly add 20x and 3 together and get 23x, So your new expression should look like 23x + 62
a car travels 45 miles and uses 3 gallons of gas. what is the unit rate for miles per gallon. HELP
Answer:

Solve system of equation algebraically
y = 2x - 3
x + y = 18
Answer:
x = 7
y = 11
Step-by-step explanation:
Given the system;
y = 2x - 3
x + y = 18
1. Approach
The easiest way to solve this system of equations is to solve the second equation for the variable (y). Then add the systems, use algebra to solve for the value of (x), then substitute that value back into one of the original equations to solve for the value of (y). Another name for the method in use is the method of elimination, this is when a [erspm manipulates one of the equations in a system of the equation such that when they add the equations, one of the variables eliminatates. Thus, they can solve for the other variable and the backsolve for the value of the unknown variable.
2. Solve one of the equations for a variable
Manipulate the system such that each equation is solved for the same variable,
x + y = 18
Inverse operations,
x + y = 18
-18 -18
x + y - 18 = 0
-y -y
x - 18 = -y
3. Use elimination
Now substitute this back into the original system,
y = 2x - 3
-y = x - 18
Add the systems,
y = 2x - 3
-y = x - 18
_________
0 = 3x - 21
Inverse operations,
0 = 3x - 21
+21 +21
21 = 3x
/3 /3
7 = x
4. Find the value of the unknown variable
Backsovle to find the value of (y),
x + y = 18
Substitute,
7 + y = 18
Inverse operations,
7 + y = 18
-7 -7
y = 11
Answer:
X=3 Y=15
Step-by-step explanation: First you need to use the problem 18/2=x to find the value of x. Now to find the value of y, you need to subtract 3 from 18. Then you solve
15=2(9)-3 15+3=18
Which of the following scatter plots shows the strongest correlation
Answer:
the first one
Step-by-step explanation:
the reason this is because it is showing a linear graph and when it comes to correlation it has to be linear
The scatter plots shows the strongest correlation in graph A. Therefore, option A is the correct answer.
What is scatter plot?Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.
A strong positive or negative correlation graph is where the line touches or is very close to every data point, and the line has a positive or negative slope.
From the graph A, we can see the points are closely aligned.
Therefore, option A is the correct answer.

What is the perimeter of AABC?
A 12 units
B. 13 units
C 15 units
D. 16 units
The solution is, 12units is the perimeter of AABC.
Here, we have,
Perimeter of ∆ABC = AB + BC + AC
Formula: distance= √(x_2-x_1)²+(y_2-y_1)²
Distance between A(1, 1) and B(4,1):
Where,
AB = √(4-1)^2 + ( 1-1)^2
AB = 3 units
Distance between B(4,1) and C(4,5)
Where,
BC = √(4-4)^2 + (5-1)^2
BC = 4 units
and, we have,
AC = 5 units
so, we get,
Perimeter of ∆ABC = 3+4+5
= 12 units
