Answer:
Step-by-step explanation:
5(x-3y)+2(4x+y)-(x+y)
5x-15y+8x+2y-x-y
5x+8x-x-15y+2y-y
13x-x-13y-y
12x-12y
explanation:
add 5x and 8x and you get 13x−15y+2y−x−y
then subtract x from 13 x and you get 12x-15y+2y-y
then you add -15y and 2y and you get 12x-13y-y
then you subtract y from -13y and you get 12x-14y (answer).

HELP!!!!!HELP!!!!When solving proportion based on data from graphs, why do you often convert from fractions and percents to decimals? URGENT!! PLEASE EXPLAIN IN DETAIL!!
Answers
Answer:
It'll simplify the calculation process.
Step-by-step explanation:
It'd be much harder to solve the problem "1/4 x 14" or "25% x 14" than just calculating "0.25 x 14". It'll also help you work on converting to different forms of numbers. Depending on the problem, you'll need to convert to a specific form, such as a problem that asks you to calculate the percent increase/decrease. If you answered with your number in decimal or fraction form, you haven't completely answered the problem. I hope this helps and sorry if it wasn't in enough detail! ♥️
the graph shows the solutions to the equation y=-4x+8. If a second equation is x=3, write an ordered pair that would be a solution to the system
Answers
Answer:
y= 3, 4
Step-by-step explanation:
y= -4x+8
x=3
y= -4(3) +8
y= -12 +8
y= 4
The ordered pair that would be a solution to the system of equation, y = -4·x + 8, and x = 3 is (3, -4)
What is a system of equations?A system of equations is a set of two or more equations with the same variables. An ordered pair that is a solution to the system is a pair of values that makes all the equations in the system true.
The system of the equation are;
y = -4·x + 8
x = 3
To find an ordered pair that is a solution to the system, the value of x in the second equation can be substituted into the first equation, to obtain, the corresponding value of y as follows;
y = -4·x + 8, x = 3, therefore, at the solution point, we get;
y = -4×3 + 8 = -4
The above values indicates that when x = 3, y = -4, and an ordered pair that is a solution to the equation is; (3, -4).
The point (3, -4) indicates that on the same coordinate plane, the graph of both equations intersect at the point (3, -4)

The perimeter of a square is 4 times the length of one side of the square. Which graph represents this situation? *
Answers
Answer:
A.
Step-by-step explanation:
Graph B must be incorrect as this is a directly proportional relationship. Likewise, graph C shows an inversely proportional relationship.
Between graph A and D, only graph A passes through the origin, which is true because if length is zero, perimeter is zero.
Hence the answer is Graph A.

In the 19th century, Britain used a money system which included pence, farthings, shillings and pounds. The following conversions were used: 4 farthings = 1 pence 12 pence = 1 shilling 20 shillings = 1 pound How many total farthings were equivalent to 1 pound and 5 pence?
Answers
The number of farthings in 1 pound and 5 pence if, 4 farthings = 1 pence, 12 pence = 1 shilling, 20 shillings = 1 pound, is 980 farthings.
What is multiplication?
The fundamental concept of making the same number of additions repeatedly is represented by the action of multiplication. The results of multiplying two or more integers are known as the products, and the factors that are used in the multiplication are referred to as the factors.
Given:
4 farthings = 1 pence, 12 pence = 1 shilling, 20 shillings = 1 pound,
Calculate the pence in one pound,
1 pound = 20 × 12 pence
1 pound = 240 pence,
1 pound and 5 pence = 240 + 5 = 245 pence,
Calculate the farthings as shown below,
245 pence = 4 × 245
245 pence = 980 farthings.

For this question, we can use the same side interior angle theorem.
Angles 1 and 2 are same side interior angles, which means that they are the interior angles on the same side.
To find the angle measure of the angles, we can plug in the value we have.
[tex]A=6x+18[/tex]
[tex]A=6(10)+18[/tex]
[tex]A=60+18[/tex]
[tex]A=78[/tex]
[tex]B=9x+12[/tex]
[tex]B=9(10)+12[/tex]
[tex]B=90+12[/tex]
[tex]B=102[/tex]
To find if the oars are parallel, we can use the same side interior angle theorem, which states that if the same side interior angles are supplementary, the lines are parallel.
[tex]78+102=180[/tex]
Seeing as the angles are supplementary, the oars are parallel to each other.
Hope this helps.
