Answer:
7
Step-by-step explanation:
5(x - 3) = 2(x + 3) Distribute
5x - 15 = 2x + 6
+ 15 + 15 Switch sides to the liked terms
5x = 2x + 6 + 15
-2x -2x Switch sides to the liked terms
5x - 2x = 6 + 15
3x = 21 Divide
3 3
x = 7
Answer:
x = 7
Step-by-step explanation:
Equation: 5(x-3) = 2(x+3)
Step 1: Simplify the equation.
5 (x − 3) = 2(x + 3)
(5)(x) + (5)(−3) = (2)(x) + (2)(3) Distribute
5x + −15 = 2x + 6
5x − 15 = 2x + 6
Step 2: Subtract 2x.
5x − 15 −2x = 2x + 6 −2x
3x − 15 = 6
Step 3: Add 15.
3x − 15 + 15 = 6 + 15
3x = 21
Step 4: Divide by 3.
[tex]\frac{3x}{3} = \frac{21}{3}[/tex]
Step 5: Divide 21 by 3.
The answer is x = 7.
A line passes through the point (10,2) and has a slope of 1/2. Write an equation in slope-intercept form for this line.
Answer:
Step-by-step explanation:
y - 2 = 1/2(x - 10)
y - 2 = 1/2x - 5
y = 1/2x - 3
Answer:
Step-by-step explanation:
You can read the slope right away.
y = 0.5x + b 1/2 = 0.5
The point will determine the y intercept
2 = 0.5*10 + b
2 = 5 + b
2-5 = b
b = - 3
The line is y = 0.5x - 3

Answer:
284 mm^2
Step-by-step explanation:
We observe that the figure is made up of 2 squares and 1 triangle.
Lets consider the bigger square.
We observe that it sides are 12 mm
Hence, its area would be the square of its sides and hence, 144 mm^2.
Lets now consider the smaller square.
We observe that it sides are 7 mm
Hence, its area would be the square of its sides and hence, 49 mm^2.
Now,
Lets take the triangle into consideration.
We observe that,
One of its segments is not given to us and needs to be computed;
Lets take the length of this segment as x
Hence,
As the one of the sides of both the squares sum up to the lengths of the segment and 8,
[tex]12+7=x+8\\12+7-8=x\\x=11[/tex]
We now find its:
Base = 3+11 =14 mm
Height = 13mm
Hence, its area would be :
[tex]\frac{bh}{2} \\=\frac{14*13}{2} \\=7*13\\=91 mm^2[/tex]
Hence,
The Sum of the total figure = Sum of Areas of both the squares and that of the triangle
Hence,
The Sum of the total figure =
[tex]91+144+49\\= 284 mm^2[/tex]
What is 180 inches in feet
Answer:15
Step-by-step explanation:
180÷12
Answer:
15 feet
Step-by-step explanation:
12 inches= 1 ft
180 inches* 1 ft/12 inches
inches and inches get canceled out and ft is the unit of measure now
180ft/ 12= 15 feet

The cost of a 20 ounce can of pineapple is $1.78 and the cost of a 6 ounce can of pineapple is $.78 To calculate the unit cost at Fergie's… you need to find the rate as cost per ounce
Answer:
Price of 1 ounce = $0.089
Price of 1 ounce = $0.089
Step-by-step explanation:
Given:
Price of 20 ounce = $1.78
Price of 8 ounce = $0.78
Find:
Price of 1 ounce
Computation:
Price of 20 ounce = $1.78
So,
Price of 1 ounce = $1.78 / 20
Price of 1 ounce = $0.089
Price of 6 ounce = $0.78
So,
Price of 6 ounce = $0.78 / 6
Price of 1 ounce = $0.089
Hannah made a ramp for her grandfather who was in a wheelchair. The ramp was 10 ft long and it was 5 ft away from the porch steps. How high were the porch steps?
Given :
Length of ramp( Hypotenuse ), l = 10 ft .
Length of base, b = 5 ft .
To Find :
How high were the porch steps.
Solution :
Let, height is h.
By Pythagoras theorem :
[tex]b^2+h^2=l^2\\\\h=\sqrt{l^2-b^2}\\\\h=\sqrt{10^2-5^2}\\\\h = \sqrt{75}\\\\h = 5\sqrt{3}\ ft[/tex]
Hence, this is the required solution.

A) Quadratic variation. This is because the equation is in the form y = kx^2 with k = 1/8.
B) Inverse variation. Recall that inverse variation is in the form y = k/x which we can solve to xy = k. Here we have k = 9.
C) Direct linear variation. This equation is in the form y = kx, which is also known a direct proportional relationship because k = y/x. In this case, k = 1/11.
