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.

Joe and Tim observed two points, P and Q, on a number line.
Joe said that the absolute values of the numbers represented by the two points are different.
Tim said that the absolute values of the numbers represented by the two points are the same.
Which of the following explains who is correct?
Joe, because the points have different signs
Tim, because each point is fraction 3 over 8 unit away from 0
Tim, because the distance between the points is fraction 3 over 8 unit
Joe, because the points are at different locations
Answer:
The answer is Tim, because each point is fraction 3 over 8 unit away from 0.
Step-by-step explanation:
The absolute value is how far away a number is from 0 on a number line so since -3/8 is still 3/8 away from 0 the absolute value would be 3/8.

Simplify 7(9x - 3) - 4(2x - 1)
34x
55x - 17
55x - 25
Answer:
the answer is the second one, 55x-17
Step-by-step explanation:
So what you do is you open the parenthesis and evaluate and simplify the expression.
Here is the simplification: (7)(9x)+(7)(−3)+(−4)(2x)+(−4)(−1)
=63x+−21+−8x+4
And reduce that further and you get 55x-17.
What is the volume of a hemisphere with a diameter of 61.5 cm, rounded to the nearest tenth of a cubic centimeter?
Answer:
60896.7
Step-by-step explanation:
The volume of the hemisphere will be 60,865.86 cubic centimeters.
What is the volume of the sphere?Volume is a proportion of consumed three-layered space. It is frequently evaluated mathematically utilizing SI inferred units or by different supreme or US standard units. Let r be the radius of the sphere.
Then the volume of the sphere will be
V = 4/3 πr³ cubic units
The diameter is 61.5 cm. Then the radius is calculated as,
r = d / 2
r = 61.5 / 2
r = 30.75 cm
The volume of the hemisphere is half of the volume of the sphere, then the volume is calculated as,
V = (1/2) x (4/3) x π r³
V = (1/2) x (4/3) x 3.14 x (30.75)³
V = 2.0933 x 29076.04688
V = 60,865.86
The volume of the hemisphere will be 60,865.86 cubic centimeters.

Which graph represents the function y = x – 2? A coordinate plane with a line passing through (0, negative 3) and (2, 0). A coordinate plane with a line passing through (0, 2) and (2, negative 1). A coordinate plane with a line passing through (0, negative 2) and (3, 0). A coordinate plane with a line passing through (0, 1.5) and about (2.25, 0).
The graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).
None of the given options is correct
The given equation is:
y = x - 2
Find the x-intercept by making y = 0 and finding the corresponding x-value
y = x - 2
0 = x - 2
x = 2
The line y = x - 2 passes through the point (2, 0)
Also, find the y-intercept by making x = 0 and finding the corresponding y-value
y = x - 2
y = 0 - 2
y = -2
The line passes through the point (0, -2)
Therefore, the graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).

Answer:
59 hamburger patties
Step-by-step explanation:
14 3/4 divided by 1/4 is 59
Answer:
Option #1 (59 hamburger patties)
Step-by-step explanation:
First, add 6 1/4 and 8 1/2 to get the total amount of pounds you have.
You find a common denominator to add. In this case, the common denominator would be 4.
8 1/2 will become 8 2/4
6 1/4 + 8 2/4 = 14 3/4
Now we divide this number by 1/4
(14 3/4)/(1/4) =
59/4 * 4/1 =
236/4 = 59

2) Orion buys 3 books for a total of $25.50. He pays $8 plus sales tax for each book. He wants
to know how much the sales tax is for one book.
) Which quantity is unknown?
.) the sales tax for each book
Let t equal the sales tax Orion pays for each book. Write an equation that
represents the situation.
3
8
25.50
t
Answer: I think the Sales tax is 0.5 because 0.5 X 3 is 1.5, He paid $24 in total for the books so you would do 24 + 1.5 and get 25.50, So it would have to be 0.5 sales tax for one book. Sorry about my English.
Answer: the equation would be 3(t + 8) = 25.50 :)
