10x- (- 4 + 7x
answer if you can :)
Answer:
17x + 4
Step-by-step explanation:
The -(- would be turned into a positive due to the rule of two negatives makes a positive. You wouldn't add the 4 into either of the numbers with a variable, you would only add the 10x and 7x.
Answer:
3x+4
Step-by-step explanation:
Apply the distributive property to get 10x - -4-(7x). Now we can turn the two negatives into a positive to get 10x+4-7x. Now, subtract 7x from 10x to get 3x. This will leave you with 3x+4.

Select the correct answer from each drop-down menu. Wayne and Winston collect old coins. Winston has 8 fewer coins than Wayne has. If you add 4 times the number of coins Wayne has and 3 times the number of coins Winston has, the sum is 375. This system of linear equations relates the number of coins Wayne has (x) and the number of coins Winston has (y). y = x − 8 4x + 3y = 375 The best method to solve this system of equations is . Wayne has coins, and Winston has coins.

Answer:
the answer is c
Step-by-step explanation:
a collection of coins consist of nickels, dimes, and quarters. there are 3 fewer quarters than nickels and six more dimes than quarters. how many of each kind of coin is in the collection if the total value of the collection is $4.35?
Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.
Creating a system of equations thus :
n + d + q = 36 - - - (1)n = q + 3 - - - (2).d = q + 6 - - - (3)Substitute for n and q
(q+3) + (q+6) + q = 36
3q + 9 = 36
3q = 36 - 9
q = 27 ÷ 3
q = 9 quarters
n = 9 + 3 = 12 nickels
d = 9 + 6 = 15 dimes
Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.

What is the area, in square units, of the parallelogram shown below?
A parallelogram ABCD is shown with height 12 units and base 8 units.
(1 point)
12 square units
24 square units
48 square units
96 square units
To figure out the area of a parallelogram, we need to identify its formula. However, I do know the formula, which is Area = Base x Height.
Area = Base x Height
Area = 8 x 12
= 96 cm squared
Therefore, the answer it 96 cm squared. By the way, I recommend that you review and comprehend the topic regarding area. Try memorizing all formulas for the shapes.
Rectangle & Square: Area = length x width
Triangle: Area = base x height
2
Trapezoid: Area = (Base 1 + Base 2) x h
2
Pararellogram: Area = base x height
Circle: Area = pi x r sqaured
Those are all the formulas I can recall; however, there might be more.

8. Conduction. (Conduction is the transfer of heat that happens when particles collide with each other. It can happen in solids, liquids, and gases.)
Before the pan is placed on the burner, its particles are moving at the same average speed. The whole pan is at the same temperature. The hot burner is at a much higher temperature. In other words, the particles that make up the burner are moving at a greater average speed and therefore have greater thermal energy.
8b. Convection. During convection, however, the particles themselves move. This happens only in liquids and gases because the particles in solids are stuck in place and cannot move.
Answer:
8. Conduction happens it transfers the heat when particles collide with each other. Before the pan is placed on the burner, its particles are moving at the same average speed. The whole pan is at the same temperature. The hot burner is at a much higher temperature, than the pan which causes the particles to move at a uneven speed.

Look at this function: x y −12 −8 −8 −6 −4 −4 0 −2 Mina said that the function is linear. Jenna said that the function is nonlinear. Which of the following explains who is correct?
Mina, because for every 2-unit increase in x, there is an increase in y by 4
Mina, because for every 4-unit increase in x, there is an increase in y by 2
Jenna, because the point (0, −2) does not lie on the straight line that contains the other points
Jenna, because the point (−12, −8) does not lie on the straight line that contains the other points
C. Because (0,-2) has a y that is 4 greater but the x is 4 greater and everything else is x+4 y+2
The graph is nonlinear, the correct option is, "Jenna, because the point (0, −2) does not lie on the straight line that contains the other points".
What is linear and nonlinear function?A linear function gives a graph that is a straight line. On the contrary, a nonlinear function gives a graph that is not a line.
Given are coordinates, (x, y) = (−12, −8), (−8, −6), (−4, −4) and (0, −2)
The graph of these coordinates is not linear, because (0,-2) has a y that is 4 greater and the x is also 4 greater and other points are (x+4, y+2)
Hence, the correct option is "Jenna, because the point (0, −2) does not lie on the straight line that contains the other points".
