p = 18.5
Step-by-step explanation:
a. to find perimeter you have to add all the sides together
So if one side is p, and the other side is 3p+2, just add them together like this
p + 3p + 2, then combine the ps so the expression is
4p + 2
b. now you find out the perimeter is 76
So put the original expression of your perimeter and 76 together like this
4p + 2 = 76
c. So now solve the equation
4p + 2 = 76
subtract 2 from both sides to get the ps alone
4p = 74
now divide by 4 to get the p by itself
74 ÷ 4 is 18.5, or 18 1/2
So p = 18.5 or 18 1/2
5(x-1)=23 solve the equation
Answer: 28/5 or 5.6
Step-by-step explanation:
5(x-1) = 23 Distribute on the left side
5x - 5 = 23 Add 5 to both sides
+5 +5
5x = 28 Divide both sides by 5
x = 28/5
Answer:
x = 28/5

Step 1: Define
5(x - 1) = 23
Step 2: Solve for x
Divide 5 on both sides: x - 1 = 23/5Add 1 to both sides: x = 28/5Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(28/5 - 1) = 23(Parenthesis) Subtract: 5(23/5) = 23Multiply: 23 = 23Here we see that 23 does indeed equal 23.
∴ x = 28/5 is the solution to the equation.

K/X=W+v solve for the letter x
Answer:
[tex]\displaystyle X=\frac{K}{W+v}[/tex]
Step-by-step explanation:
Equation Solving
Equations are solved for a given variable by performing a sequence of operations that lead to the variable to be alone, usually on the left side of the equation.
We are given the equation:
[tex]\displaystyle \frac{K}{X}=W+v[/tex]
It's required to solve it for X.
Note X is in the denominator of a fraction. To solve for X, we simply take the reciprocal on both sides of the equation:
[tex]\displaystyle \frac{X}{K}=\frac{1}{W+v}[/tex]
Now multiply by K:
[tex]\boxed{\displaystyle X=\frac{K}{W+v}}[/tex]
the graph shows the number of quarts picked the graph shows the number of quarts picked and amount of money paid by different customers
Answer:
Step-by-step explanation:
Part A
Since, line shown in the graph passes through origin (0, 0), relation between number of quarts picked (Q) and amount of money paid (M) will be proportional.
M ∝ Q
M = kQ [k = proportionality constant]
k = Slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Since, line passes through two points (1, 3.5) and (2, 7),
k = [tex]\frac{7-3.5}{2-1}[/tex] = 3.5
Therefore, M = 3.5Q
This relation states that "For each number of quarts picked, $3.5 is to be paid"
Part B
Equation that represents the proportional relation,
y = 3.5x
Or Amount of money paid = 3.5(Number of quarts picked)

a rectangular box has length 20 cm width 6 cm and height 4 cm find how many cubes of side 2 cm that will fit into the box
Answer:
60Step-by-step explanation:
Get the volume of the rectangular box
Volume of the rectangular box = length * width * height
Volume of the rectangular box = 20 * 6 * 4
Volume of the rectangular box = 480cm³
Get the volume of the cube;
Volume of the cube = l³
Volume of the cube = 2³
Volume of the cube = 8cm³
Amount of 2cm³ cube that will fit = volume of the box/volume of the cube
Amount of 2cm³ cube that will fit = 480/8
Amount of 2cm³ cube that will fit = 60
Hence 60 2cm³ cube will fit into the box

This would be the equation, I just answered a similar question for another fellow/lady. So how it would look for future reference is
√(xa - xb) 2 + (ya - yb) 2
The 2s would be small signifying that you would square it ( lol guessing you know that) and the xa - yb would be the cordinates. A for the first set of numbers and B for the second set of numbers.

Bill has 5 cups of strawberries he uses 2 and 1/6 to make smoothies he uses the rest of the strawberries to make fruit cups he needs 2/3 cups of strawberries for each fruit cup how many fruit cups can he make
Answer: Total fruit cups made = [tex]4\dfrac14[/tex]
Step-by-step explanation:
Total cups of strawberries = 5
Cups used for smoothies = [tex]2\dfrac16=\dfrac{13}{6}[/tex]
Since rest of the strawberries are used to make fruit cups = [tex]5-\dfrac{13}{6}=\dfrac{30-13}{6}=\dfrac{17}{6}[/tex]
Cups of strawberries for each fruit cup = [tex]\dfrac23[/tex]
Total fruit cups made = (rest of the strawberries ) ÷(Cups of strawberries for each fruit cup)
[tex]=\dfrac{17}{6}\div \dfrac23\\\\=\dfrac{17}{6}\times\dfrac32\\\\=\dfrac{17}{4}\\\\=4\dfrac14[/tex]
∴ Total fruit cups made = [tex]4\dfrac14[/tex]
