Answer:
-x+y= -14 (get this equation to where you can easily plug it in for a variable)
y= x -14
5x +6y =26 (plug the value above in for y and then solve)
5x + 6 (x-14) = 26 (use the distributive property)
5x +6x - 84 = 26 (combine like terms on the left side)
11x - 84 =26 (add 84 to both sides)
11x = 110 (divide both sides by 11 to isolate the x-variable)
x= 10 (this is the value for x. plug it into the easier equation and solve)
-(10) +y = -14
y= -4
(10, -4) (this is the solution for the system of equations)

x is a negative integer which is the largest
7x+4
x-4
5x
-5x
Answer:
-5x
Step-by-step explanation:
Remember, if you multiply a negative number by a negative number, you will get a positive number, and positive numbers are greater than negative numbers. In this case, if I were to multiply each of these expressions with -1, I would get the following:
7(-1)+4=-3
-1-4=-5
5(-1)=-5
-5(-1)=5
And I'm sure you can imply how these values will correspond to other negative values. Basically, the last expression gives us a positive answer, which is larger than the others (which give a negative answer).
-5x will be the largest among the options since x is the negative integer.
What is a negative integer?On the number line, a negative integer is an integer that is to the left of zero. It is not equal to zero.
Given, x is a negative integer, all given options will become negative except " -5x". written with a minus sign. a number smaller than zero, but not a fraction or a decimal fraction.
Since for any value of x, all the given options will be negative.
Therefore, Due to the fact that x is a negative integer, -5x will be the largest selection.

Put the following numbers in order from least to greatest. 9.201, 9.210, 9.012, 9.0
Answer:
9.0, 9.012, 9.201, 9.210
Step-by-step explanation:
9.0 has no decimal numbers, so it goes at the beginning, 9.012 is the next greatest, then 9.201, and finally, 9.21. Also, a zero at the end of a decimal number adds nothing.
Solve the equation: 2 (x + 2x) - 36
A) X=-18
B) x = 18
cx = -6
D) x = 6
______________________________
1.) Divide both sides by 2:[tex]2[/tex] ÷ [tex]2=[/tex] Cancels Out[tex]36[/tex] ÷ [tex]2=18[/tex]
- We do this first because we need the get rid of the parenthesis in order to solve this like a regular problem. In this case the only way to do so was to divide by 2 to separate the Number/Variable from the parenthesis.
Equation at the end of Step 1:
[tex]x+2x=18[/tex]2.) Combine x and 2x:[tex]x+2x=3x[/tex]
- We do this because we can't have 2 variables at the end of the equation so it's best to just combine them.
Equation at the end of Step 2:
[tex]3x=18[/tex]3.) Divide both sides by 3:[tex]3x[/tex] ÷ [tex]3=x[/tex][tex]18[/tex] ÷ [tex]3=6[/tex]- We divided for the last step since their was 1 variable connected by a number and another number on the opposite side of the equal.

x + 3y = 18
-X - 4y = -25
Answer:
x = -3
y= 7
Step-by-step explanation:
x + 3y=18 ----(1)
-x - 4y=-25 -----(2)
from equation (1)
x = 18 - 3y ---(3)
putting equation (3) into equation (2)
-(18 - 3y) - 4y = -25
18 + 3y -4y = -25
3y - 4y = -25 - 18
-y = -7
y = 7 ✓
Putting y=7 into equation (1)
x + 3(7) = 18
x + 21 = 18
x = 18 - 21
x = -3 ✓

Colin gets £x wages each week. After he pays his tax of £t, he
then pays his rent of £120. He shares what's left between
himself and his wife. How much do they each get?
Answer:
They will each get ;
(x-t)/2 - 60
Step-by-step explanation:
Here, we want to know the amount of money that Colin and his wife gets
we start by subtracting the necessary terms
Mathematically, that would be;
x-t-120
So what each of them get will be;
(x-t-120)/2
= (x-t)/2 - 60

June was thinking of a number. June doubles it and gets an answer of 98.9. What was the original number?
Answer: 49.45
Step-by-step explanation:
From the information, we are informed that June was thinking of a number and then doubles it and gets and gets an answer of 98.9.
Let the number be represented by x.
Since she doubles it, thus implies that:
2x = 98.9
x = 98.9 / 2
x = 49.45
The number is 49.45

What is the area of the football field in the scale drawing? Assume that the field is shaped like a rectangle.
Answer:
i mean might as well get free points now that its 2 weeks old
Step-by-step explanation:
Answer:
Pythagorean Theorem: the diagonal of the football field is the hypotenuse. Let´s say the diagonal is C and the two other sides are A and B.
Width = A
Length = B
Diagonal = C
so: a2+b2=c
2502+1002=c2
2500+10000=c2
12500=c2
c=√12500
c=111.80 yards

HELP, NO SCAM ANSWERS PLEASE!
Answer:
c = 2.99m+ 6.85
Step-by-step explanation:
one time fee of 6.85
2.99 per movie rental
in other words you must pay 6.85
and 2.99 times the number of movies you watch
m = movies watched
c = cost
therefore
c = 2.99m+ 6.85
watching 13 movies at movie mania would mean that m (movies watched) would be 13
put that into the equation:
c = 6.85+ 2.99(13)
c = 6.85+ 38.87
c = 45.72
