Answer:

Step-by-step explanation:

Making x the subject of the formula;

y=x+z/a-x

Cross multiply

y(a-x) = x+z

ya - yx = x+z

Collect like terms

x+yx = ya - z

x(1+y) = ya - z

x = ya-z/1+y

Hence the value of x is ya-z/1+y

Answer:

[tex]\frac{ya-z}{1+y} = x[/tex]

Step-by-step explanation:

[tex]y=\frac{x+z}{a-x}[/tex]

Use cross multiplication

y ( a - x) =  x + z

Solve the brackets.

y a - y x = x + z

y a - y x - z = x

y a - z = x + y x

y a - z = x ( 1 + y )

Divide both sides by ( 1 + y ).

[tex]\frac{ya-z}{1+y} = x[/tex]

Step-by-step explanation:

the ladder and the wall form a right angle triangle with sides a, b, and c. Remember that side c is the hypoteneuse, which is formed by the ladder in this case. the choice of which side is a and b is arbitrary. Solve for the missing side using pythagorean theorem.

[tex]c^2=a^2+b^2\\b^2=c^2-a^2\\b^2=17^{2}-5^{2}\\b^2=264\\b=\sqrt{264}\\b=16.25[/tex]

where side b is the height on the wall which the ladder reaches.

Answer:

Constant of proportionality(X:Y) = 1:6

Step-by-step explanation:

Given:

X- 5, 6, 7, 8, 9

Y- 30, 36, 42, 48, 54

Find:

Constant of proportionality

Computation:

X/Y = 5/30 = 6/36 = 7/42 = 8/48 = 9/54

X/Y = 1/6 = 1/6 = 1/6 = 1/6 = 1/6

So;

Constant of proportionality(X:Y) = 1:6

Answer:

D.) 9√2

Step-by-step explanation:

a^2 + b^2 = c^2

x^2 + 8^2 = √226^2

x^2 + 64 = 226

x^2 = 226 - 64

x^2 = 162

√x^2 = √162

√162 = √81 • √2

√81 = 9

√2 = √2

Step-by-step explanation:

Answer:

h = 23 hours

Step-by-step explanation:

Take 143.75 and divide it by 6.25

143.75/6.25 = 23

23 is the answer

Answer:

6.25h ≥ 143.75; h ≥ 23; 23 hours

Step-by-step explanation:

Levi earns $6.25 per hour after school. Since he needs at least $143.75 to get a stereo the amount he wants should be equal to or greater than  $143.75.

Let h = number of hours worked

The expression can be written as follows:

6.25 × h ≥  143.75

6.25 h ≥  143.75

divide both sides by 6.25

h ≥ 143.75/6.25

h ≥ 23 hours

Answer:

18k + 22p -10

Step-by-step explanation:

The solution is Option B

The equation to represent the total cost for Mr.Thompson to rent a kayak for k hours and paddle board for p hours is A = 18k + 22p - 10

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the cost of renting a kayak per hour be = $ 18

Let the number of hours of renting the kayak be = h

Let the cost of renting a paddle board per hour be = $ 22

Let the number of hours of renting the paddle board be = p

Let the discount of cost as coupon = $ 10

Now , the total cost of renting at Cycle and Sports for Mr. Thompson A =
( cost of renting a kayak per hour x number of hours of renting the kayak ) +
( cost of renting a paddle board per hour x number of hours of renting the paddle board ) -  discount of cost as coupon

Substituting the values in the equation , we get

Total cost for Mr.Thompson to rent a kayak for k hours and paddle board for p hours A = 18h + 22p - 10

Therefore , the value of A is 18h + 22p - 10

Hence , the equation for total cost is A = 18h + 22p - 10

Answer:

Each cookbook cost $15.15.

Step-by-step explanation:

Since the statement indicates that four cookbooks and one novel cost $68.75, you can write the following equation:

4x+y=68.75, where:

x is the price of cookbooks

y is the price of novels

Also, given that the novel cost 7 dollars less than a cookbook, you can write the following equation:

x=y+7

Now, you can replace x=y+7 in the first equation:

4(y+7)+y=68.75

4y+28+y=68.75

5y=40.75

y=40.75/5

y=8.15

Now, you can replace the value of y in x=y+7:

x=8.15+7

x=15.15

According to this, the answer is that each cookbook cost $15.15.

Answer:

D

Step-by-step explanation:

First, we can find the volume of the rectangular prism.

As shown in the image, the dimensions are 4 by 4 by 9.

So,

4 * 4 * 9 = 144.

Now, we find the volume of the triangular prism.

As shown in the image, the dimensions are 3 by 4 by 9.

So,

3 * 4 * 9 = 108.

Now we add the volumes together:

144 + 108 = 252.

So, the answer is option D: 252 cubic meters.
