Answer: A: substitution method
Step-by-step explanation:
The substitution method is one way of solving systems of equations. To use the substitution method, use one equation to find an expression for one of the variables in terms of the other variable. Then substitute that expression in place of that variable in the second equation.

The prism shown has a volume of 35 cm.
Work out h, the height of the triangular cross section.
h
7 cm
Hem
Answer:
1.25cm
Step-by-step explanation:
Complete question:
The prism has a volume of 35 cm cubed workout h, the height of the triangular cross section
length=7cm
width = 4cm
The volume of the prism is expressed as;
Volume = Base Area * Height
Given
Volume of the prism = 35cm^3
Base Area = length * width
Base Area = 7cm * 4cm
Base Area = 28cm^2
Substitute the given values into the formula
35 = 28* Height
Cross multiply
35 = 28 * Height
35 = 28 Height
Height = 35/28
Height = 1.25cm
Hence the height of the triangular cross section is 1.25cm

The velocity of the train is 30 km/h west.
Definition of velocityVelocity can be determined by dividing the total displacement travelled by the total time travelled. The direction of travel is also added.
Calculation of velocity Total displacement = 80 km + 40 km = 120 km Total time = 1 hour + 1 hour + 2 hours = 4 hours Direction = westVelocity = 120 km / 4 hours = 30 km/h west.

Find the slope of the linear function. 12x=-10+2y
Answer: The slope is 6
The attachment shows the graph of this equation.
Step-by-step explanation: It will help to put this equation in order.
We can get standard form by subtracting 2y from both sides
12x=-10+2y becomes 12x - 2y = -10
For slope-intercept form, y = mx + b, m is the slope, b is the y-intercept
we need to isolate y on the left. Subtract 12x from both sides.
12x - 2y = -10 becomes -2y = -12x - 10
Then divide both sides by -2 to end up with
y = 6x + 5
The slope is m, the coefficient of the x,
That is 6 in this equation.
Kluber lives 450 miles away from an amusement park. He is taking his family to an amusement park, leaving his house and traveling at an average speed of at least 65 miles per hour to the park but at most 80 miles per hour. Create a system of linear constraints that model the distance he is away from the park, d, after t hours. Then evaluate the inequality for t=3 and interpret the answer within the context of the scenario.

Solve the equation for v
[tex]y=\frac{8}{av} +7[/tex]
Answer:
[tex] v = \dfrac{8}{a(y - 7)} [/tex]
Step-by-step explanation:
[tex] y = \dfrac{8}{av} + 7 [/tex]
Subtract 7 from both sides.
[tex] y - 7 = \dfrac{8}{av} [/tex]
Multiply both sides by v.
[tex] v(y - 7) = \dfrac{8}{a} [/tex]
Multiply both sides by 1/(y - 7).
[tex] v = \dfrac{8}{a(y - 7)} [/tex]

D.

Please help will give 10 points
We defined an argument as a reasoned or thoughtful process. The correct option is A.
What is an argument?An argument is a statement or set of claims known as premises that are designed to assess the degree of truth or acceptability of another statement known as the conclusion. Arguments may be analyzed from three different perspectives: logical, dialectical, and rhetorical.
Since the act or process of arguing, reasoning, or discussing is known as an argument. Therefore, we defined an argument as a reasoned or thoughtful process.
An argument is made up of three parts: the conclusion, the premises, and the assumptions.
THE ConclusionThe conclusion (or theses) is the point of the argument's major idea—what the author is attempting to show.
THE LOCATIONThe premises are the reasoning or evidence provided by the author to justify the conclusion.
THE ASSURANCESThe assumptions support the conclusion, but unlike the premises, they are unsaid and so invisible.
They connect the premises and conclusions.

Greta has two pet lizards draco and lizzy for every 11 crickets Greta feeds draco she always feeds lizzy 8 crickets last week Greta fed draco 77 crickets
greta fed lizzy 56 crickets
Answer:
She feeds Lizzy 56 crickets when she feeds Draco 77.
Step-by-step explanation:
Lets put it as an equality:
[tex]\frac{11}{8}[/tex] = [tex]\frac{77}{x}[/tex]
We want to solve for x. We can do so by finding how much larger the second fraction is than the first. In this case, 77 is 7 times larger than 11 (77/11=7), so we know that x must also be 7 times larger than 8 (because the fractions are proportional).
Since x is 7 times larger than 8, we can use 7 times 8 to find the value.
7 times 8 is 56
56 crickets for Lizzy!
Hope this helps and makes sense!
