Turtles need only part of their tank filled with water. What is the total amount of water needed, to the nearest cubic inch, to fill 40% of the aquarium with water?
Answer:
147
Step-by-step explanation:

4y = -20 + 8x²
Solve the first equation for y and substitute it into the second equation. The resulting equation is
A. 4y = 16x² - 60
B. 8x² - 20 = -20 + 8x²
C. 2x² = 5 + 2x² - 5

Answer:
x<3
Step-by-step explanation:
Answer:
x<3
Step-by-step explanation:
here are the steps :) -
4x-7<5 given
4x-7+7<5+7 add 7 on both sides to cancel out the -7 so we can get x alone
4x<12 simplify
x<3 divide by 4 on both sides to get x alone
x<3 answer

45 + 60 = 15 x ___ + 15 x ___
Answer:45+60=15x+15x
Step 1: Simplify both sides of the equation.
45+60=15x+15x
(45+60)=(15x+15x)(Combine Like Terms)
105=30x
105=30x
Step 2: Flip the equation.
30x=105
Step 3: Divide both sides by 30.
30x/30= 105/30

The length of a rectangle is 12ft longer than twice the width. If the perimeter is 108ft, find the length and width of the rectangle.
Answer:
Down below
Step-by-step explanation:
P = 2L + 2W
P = 108
L = 2W+12
108 = 2(2W+12) + 2W
108 = 4W + 24 + 2W
108 = 6W + 24
84 = 6W
14 = W
W = 14
If the width is 14, then the length is twice that plus 12, or 38
38 + 38 + 14 + 14 = 108
What value of ‘x’ would make lines n and m parallel? Please explain your answer!
Answer:
The value of x is 70°
Step-by-step explanation:
Lines and Angles
We need to find the value of x that makes lines n and m parallel.
Please refer to the image below where we have added new variables to the original drawing.
If n and m were parallel, then:
y and 30° are corresponding angles, having the same measure.
w and 80° are vertical angles, having the same measure.
If the two above conditions are met, then the triangle has the angles y, w, and x. Since the sum of all internal angles of a triangle is 180°:
x + y + w = 180°
Substituting:
x + 30° + 80° = 180°
Solving for x:
x = 180° - 30° - 80°
x = 70°
The value of x is 70°
hey i need help and Use mental math to solve the equation.
x – 16 = 14
A. 30
B. 2
C. –2
D. –30
i think the answer is c
Answer:
A. 30
Step-by-step explanation:
This is a common mistake when you often second guess yourself. Since this is an algebra equation, you want to solve for the value of x and x alone since you are going to isolate the variable. The only way to do this equation is to add 16 on both sides to get 30 which is your final answer.
Answer:
A
Step-by-step explanation:
add 16 on both sides. and simply

How do you decide which variable to isolate in order to use the substitution method to solve a system of linear equations?
Answer:
Look Below!
Step-by-step explanation:
Whichever is easier for you.
For example, 2y = 8x + 10
It is easier to isolate y by dividing both sides by 2
Example 2: 8x = 16y + 24
In this case, x is easier to eliminate by dividing both sides by 8
There is no real rule to decide which variable to isolate, you just isolate the easier one. Or in the cases where you want to solve the system for only one variable, you need to isolate the other.
Solving a system of equations by substitution.Assume we have a system of equations with 2 equations and 2 variables (the simplest system, we could have N equations and N variables).
To solve the system by substitution, what you need to do is isolate one of the variables in one of the equations and then replace that in the other equation.
Now, which variable we should isolate?If you want to solve the system for only one variable (for example a problem with the variables x and y, and you only want to know the value of x).
Then you need to isolate the other variable and in that way, the problem will be simpler.
If that is not the case, it depends on you, I usually isolate the variable that is easier to isolate, and then work from that.
