Answer:

90 ft

Step-by-step explanation:

first you find the area of the 10 by 3 triangle, since on the other side it,s the same, all we need to do is find one of each triangle then mulitply it by 2 to get the area. then find the area of the 20 by 3 triangle. once you do that you will get 45, then you multiply it by 2 because it is the exact same on the other sides. then when you do that you get 90 ft. I hope this helps you! peace out.

To use substitution to evaluate this system of equations, the y value to be substituted is 2x - 7.

<h3>What is method of substitution?</h3>

The algebraic method for solving simultaneous linear equations is the substitution method. The values of one variables from one expression is substituted with in second equation, as the name implies.

Now according to the question;

The expressions are as follows;

4x = 5 – 2y and y – 2x + 7 = 0

To solve the following system of equations, we must determine what substitution must be made in place of y in the first equation.

Let us now deduce the value of y from the second equation.

y – 2x + 7 = 0 ⇒ y = 2x – 7

We now have the y value, which we can plug into the first equation;

⇒ 4x = 5 – 2(2x – 7)

4x = 5 – 4x + 14

4x + 4x = 5 + 14

8x = 19

x = 19/8

Substitute the value of x in y to get its value.

y = 2×(19/8) - 7

y = -9/4

Thus, the values obtained for the given set of equations are-

x = 19/8 and y = -9/4 by method of substitution.

MariettaO [177]

Answer:

14 cm.

Step-by-step explanation:

We have been given that an aquarium is a right rectangular prism 18.5 cm long and 15 cm wide. We are also told that Martene put 3885 cubic cm of water in the aquarium.

To find the depth or height of aquarium, we will use volume of rectangular prism formula.

$\text{Volume of rectangular prism}=l*w*h$ , where,
