Find the sum (3.2+4x)+(18.25+6x)
Answers
Answer:
10x+21.45
Step-by-step explanation:
3.2+4x+18.25+6x
we combine like terms
4x+6x+3.2+18.25
10x+21.45
hopes this helps please mark brainliest
First write the equation without parentheses:
3.2 + 4x + 18.25 + 6x
Then combine like terms:
4x + 6x = 10x,
18.25 + 3.2 = 21.45
Plug the results and rewrite the expression:
21.45 + 10x
Finally, 21.45 + 10x should be your answer.
I’m pretty sure since this is an expression (because there’s no equal sign) and not an equation, you don’t determine the actual value of x or the sum of the numbers. In order to do that, you would need to be provided with the value of x or a number with an equal sign that the problem would equal to, so that’s why it’s still written with a plus sign as an expression.
I hope this helps! Please correct me if I’m wrong! :)
Rita is playing a game by rolling a rectangular prism made up of cubes. The prism is 6 cubes wide, 3 cubes high, and 4 cubes deep. Rita rolls the cube and says that the top view is a 6-unit by 4-unit rectangle.
Which statement explains whether Rita could be correct?
Rita could be correct because the cube could land so the 3-cube height and the 4-cube depth make up the top face of the cube.
Rita could be correct because the cube could land so the 6-cube width and the 4-cube depth make up the top face of the cube.
Rita could not be correct because the top face of the cube is made up of the 6-cube width and the 4-cube depth.
Rita could not be correct because the top face of the cube is made up of the 6-cube width and the 3-cube height.

As Evin is driving her car, she notices that after 1 hour her gas tank has 7.25 gallons left and after 4 hours of driving, it has 3.5 gallons of gas left in it. Assuming the relationship between h, hours, and g, gallons, is linear, write an equation for g in terms of h.
I will mark brainliest to the first person who answers.
Answers
The equation representing the gas left in h hours is g(h) = 8.5 - 1.25h
What is the concept of a linear equation?When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. An equation is an algebraic statement that demonstrates two mathematical expressions are equivalent in algebra, and this is how it is most usually used.
A linear equation is written as
y = mx + b
Where (x, y) is the ordered pair and m is the rate of change and b is the y-intercept.
Let x = time in hours
y = amount of gallons left
So, according to the question, 7.25 gallons of gas is left after 1 hour. So,
(x₁, y₁) = (1, 7.25)
3.5 gallons of gas left after 4 hours, so
(x₂, y₂) = (4, 3.5)
Find the slope
m = (y₂ - y₁) / (x₂ - x₁)
= (3.5 - 7.25)/ (4-1)
= -3.75/ 3
= -1.25
Put values of m = -1.25, (x, y) = (1, 7.25) in y= mx+b
So, 7.25 = -1.25 +b
b = 7.25 +1.25
b = 8.5
So, the linear equation for the situation in terms of g and h is
g(h) = -1.25h + 8.5

A(6,2), B(2,4) and C(8,-4) are three points in a plane. P is a point on the line BC and Q is a point in the plane such that PAQB is a rectangle. Find the:
(i) equations of the sides AP and BP,
(ii) coordinates of the point P,
(iii) area of the rectangle.
Answers
(i) The equations of the sides AP and BP are y = 0.75x - 2.5 and y = (-4/3)x + (20/3), respectively.
(ii) The coordinates of the point P are (4.4, 0.8).
(iii) The area of the rectangle is 8 square units.
A (6, 2), B (2, 4) and C (8, -4) are three points in a plane. P is a point on the line BC, and Q is a point in the plane, such that PAQB is a rectangle.
The point P lies on the line BC. The equation of the line BC will be the same as that of BC. The equation of line BP is calculated below.
(y - y1) = [(y2 - y1)/(x2 - x1)]*(x - x1)
(y - 4) = [(-4 - 4)/(8 - 2)]*(x - 2)
y - 4 = (-8/6)*(x - 2)
y = (-4/3)x + (20/3)
The line AP must be perpendicular to the line BP because they are the sides of a rectangle. The equation for AP is calculated below.
y = mx + c
y = (3/4)x + c
It passes through (6, 2).
2 = (3/4)*6 + c
c = 2 - 4.5
c = -2.5
The equation of AP is y = 0.75x - 2.5.
The coordinates of P are calculated by finding the intersection point of the equations of AP and BP. The coordinates of P are (4.4, 0.8).
The length of the rectangle is BP. The width of the rectangle is AP. These are calculated below using the distance formula.
BP = √[(2 - 4.4)² + (4 - 0.8)²]
BP = √(5.76 + 10.24)
BP = 4
AP = √[(6 - 4.4)² + (2 - 0.8)²]
AP = √(2.56 + 1.44)
AP = 2
The area of the rectangle is calculated below.
A = BP*AP
A = 4×2

Answers
Independent events are not affected by previous events, that is, the probability of a new event doesn't change from the previous event. However, disjoint sets mean they don't have any data in common, which means the intersection of such sets is impossible. In other words, the events are exclusive, if one occurs, then the other can't occur.
Having said that, we can deduct that scenario 1 represents an independent exclusive event because the occurrence of one event excludes the other. The main reason is that there's just one orange marble.

Jason is a high school basketball player. In a particular game, he made some free
throws (worth one point each) and some two point shots. Jason made a total of 13
shots altogether and scored a total of 20 points. Write a system of equations that
could be used to determine the number of free throws Jason made and the number of
two point shots he made. Define the variables that you use to write the system.
Answers
The total number of free throws shots Jason made was 6 and the total number of two point shots Jason made was 7.
First, let us understand the variables:
Any number, vector, matrix, function, its argument, set, or one of its elements can be specifically represented by a variable.
Let x and y be the quantity of shorts.
x is the number of attempts at the free throw line.
y is the quantity of two-point attempts.
According to the question, we have;
x + 2y = 20 ............equation 1
x + y = 13 ............equation 2
From equation 2 we can take out the value of x;
x = 13 - y ............equation 3
substituting the value of x in equation 1, we will get;
(13 - y) + 2y = 20
13 - y + 2y = 20
13 + y = 20
y = 20 - 13
y = 7
putting the value of y in equation 3, we will get
x = 13 - 7
x = 6
Thus, the total number of free throws shots Jason made was 6 and the total number of two point shots Jason made was 7.
