Hi there!
[tex]\large\boxed{x = \frac{24z}{(18 + yz)} }[/tex]
We can begin solving by creating a common denominator:
x · 3 · z = 3xz. This is the denominator that all of the numerators must have in order to work with the fractions.
Multiply each numerator by the missing parts of the common denominator:
[tex]\frac{8 * 3 * z}{3xz} - \frac{y * x * z}{3xz} = \frac{6 * 3 * x}{3xz}[/tex]
Simplify:
[tex]\frac{24z}{3xz} - \frac{yxz}{3xz} = \frac{18x}{3xz}[/tex]
Move all the fractions involving x in the numerator to the right-hand side of the equation:
[tex]\frac{24z}{3xz} = \frac{18x}{3xz} + \frac{yxz}{3xz}[/tex]
Combine fractions:
[tex]\frac{24z}{3xz} = \frac{18x + yxz}{3xz}[/tex]
Multiply both sides by 3xz:
[tex]24z = 18x + yxz[/tex]
Factor out "x" from the terms on the right-hand side:
[tex]24z = x(18 + yz)[/tex]
Divide both sides by (18 + yz)
[tex]\frac{24z}{(18 + yz)} = x[/tex]

Investors buy a studio apartment for $140,000. Of this amount, they have a down payment of $21,000. Their down payment is what percent of the purchase price? What percent of the purchase price would a $7,000 down payment be?
Answer:
a. Down payment of $21,000
= 21,000 / 140,000
= 0.15
= 15%
b. Down payment of $7,000
= 7,000/ 140,000
= 0.05
= 5%

Treys grandmother stores her picture frames in a box. Each side of the box is 20 inches long. Trey wants to know the volume of the box
Answer:8000
Step-by-step explanation:
The Volume of the box will be 8000 in.³
What is volume ?
Volume is a three dimensional space occupy by the body of particular shape such as here :
It should be noted that a box has six sides that are equal. In this case, we've been given the side of one of the lengths to be 20 inches.
The volume of a cube is :
V = a³
Therefore, the Volume of the box will be :
V = 20³
V = 8000 in.³
Therefore, the Volume of the box will be 8000 in.³

x – 7y = –11
5x + 2y = -18
Answer:
hope this help you
Step-by-step explanation:
Simplifying
X + -7y = -11
Solving
X + -7y = -11
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '7y' to each side of the equation.
X + -7y + 7y = -11 + 7y
Combine like terms: -7y + 7y = 0
X = -11 + 7y
Simplifying
X = -11 + 7y
------------------------------------------------------------------------------------------------------------
Solving
5x + 2y = -18
Solving for variable 'x'.
Add '-2y' to each side of the equation.
5x + 2y + -2y = -18 + -2y
Combine like terms: 2y + -2y = 0
5x = -18 + -2y
Divide each side by '5'.
x = -3.6 + -0.4y
Simplifying
x = -3.6 + -0.4y

Find the area of the isosceles triangle. please help thanks
Answer:
1080 m^2 Don't submit m^2 in your answer.
Step-by-step explanation:
Givens
The catch is to find h
To do that, use a^2 + b^2 = c^2
a b and c are in the same 1/2 triangle.
a = 48/2 = 24 m
b = h = ?
c = 51 meters
Solution
a^2 + b^2 = 51^2 Substitute for b^2 = h^2
24^2 + h^2 = 51^2 Expand 24^2 and 51^2
576 + h^2 = 2601 Subtract 576 from both sides
h^2 = 2601 - 576
h^2 = 2025 Take the square root of both sides
h = 45
Area
Area = 1/2 b * h
Area = 1/2 48 * 45
Area = 1080
Remark
Notice that to find h you only use 1/2 of 48 because that is the base of the right triangle.
To find the area, you need to use all of 48 because 48 is the full length of the base.

When exercising, the maximum heart rate (r ) in beats per minute is modeled by the equation shown in the box, where (a ) represents the age of the person in years. r = 220 - a If Sanchez is 34 years old, what is his maximum heart rate?
Answer:
186 beats per minute
Step-by-step explanation:
The maximum heart rate (r ) in beats per minute is modeled by the equation :
r = 220 - a ...(1)
Where
a is age of the person in years
If Sanchez age is, a = 34 years
Put a = 34 in equation (1)
r = 220 - 34
= 186 beats per minute
Hence, the maximum heart rate is 186 beats per minute.
