Answer:
Step-by-step explanation:
x + x + 2 = 86 Two even numbers add to 86
2x + 2 = 86 This is the equation. Subtract 2 from both sides
2x = 86 - 2
2x = 84 Divide by 2
2x/2 = 84/2
x = 42
(42, 44)
-9x -2y=3
- 2x-y=-1

7d – 4d – 3d – 5 = 6d
Answer:
[tex]d = -\frac{5}{6}[/tex]
Step-by-step explanation:
7d – 4d – 3d – 5 = 6d
(7d - 4d = 3d)
3d - 3d -5 = 6d
(3d - 3d = 0)
0 - 5 = 6d
-5 = 6d

Select the true statement about triangle ABC.
A. sin C = tan A
B. sin C = cos B
C. sin C = cos A
D. sin C = sin A
Answer:
C
Step-by-step explanation:
sin C=12/13
cos A=12/13
so sin C=cos A
The trigonometric function gives the ratio of different sides of a right-angle triangle. The correct option is C.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
Let's solve the given statement as shown below.
A.)
sin C = tan A
sin C = 12/13
tan A = 5/12
Therefore, the given equation is not true.
B. sin C = cos B
sin C = 12/13
cos B = 5/13
Therefore, the given equation is not true.
C. sin C = cos A
sin C = 12/13
cos A = 12/13
Therefore, the given equation is true.
D. sin C = sin A
sin C = 12/13
Sin A = 5/13
Therefore, the given equation is not true.

Solve the equation 3x-4=8-x
Answer:
x=3
Step-by-step explanation:
3x-4=8-x(Group like terms)
3x+x=8+4(Add both sides)
4x=12(After adding you will proceed to divide both sides by 4)
x=3(x is 3 because 4 can divide 12 3 times that's why we have x as equal to 3)

The volume of the large cube is 125 cubic inches. The volume of the small cube is 27 inches. What is the difference between the length of one side of the large cube and the length of one side of the small cube?
Answer:
2cmStep-by-step explanation:
Step one:
given data
for the large cube
the volume= 125cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
125=l^3
l=∛125
l=5cm
Step two:
given data
for the large cube
the volume= 27cm^3
we know that volume = l*l*l
volume=l^3
we want to find l, so we have to cube both sides
27=l^3
l=∛27
l=3cm
The difference between the length of one side of the large cube and the length of one side of the small cube=5-3= 2cm12x+y when x=3 and y=52
John owed his brother $25.75, but was able to pay him back $19.45. How much does John owe brother owe now?
Answer:
$6.30
Step-by-step explanation:
So we are going to subtract what is owed by what is payed back to find out how much John owes his brother
$25.75 - $19.45 = $6.30
John owes his brother $6.30
Pam is having a yard sale. For each item, she is asking for two-fifths of the price for which she bought the item. Write an equation for the situation, where y is the price she is asking and x is the original price of the item.
Answer:
The equation is 2x = 5y
Step-by-step explanation:
From the question, we are told that what is asked is 2/5 of the price for which each of the items are bought
y is the asking price, x is the original
Mathematically,
that would be;
y = 2/5 * x
y = 2x/5
Thus;
2x = 5y

Given A (4,2) and B (-1,y), what is y when the slope of AB is -7/5?
Answer: y= 9
Step-by-step explanation:
3) Solve this system of linear equations by elimination.
y=x-1
2x-y=0
*x=-1,y=-2
*x=1,y=2
*x=2,y=1
*x=-2,y=-1
Answer:
Solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.
Step-by-step explanation:
We are given equations:
[tex]y=x-1---eq(1)\\2x-y=0---eq(2)[/tex]
We need to solve by Elimination method.
Elimination method: Add or subtract the equations to get an equation in one variable.
Rearranging the equation 1 we get
[tex]-x+y=-1---eq(1)\\2x-y=0---eq(2)[/tex]
Add eq(1) and eq(2)
[tex]-x+y=-1\\2x-y=0\\------\\x=-1[/tex]
So, after eliminating y we get x=-1
Now finding y by putting x in eq(1)
[tex]y=x-1\\y=-1-1\\y=-2[/tex]
We get y=-2
So, solving this system of linear equations by elimination we get x=-1 and y=-2
Option 1 is correct option.

What is 7x=5y x 6. Plllllssss heeelllp meh. Im stupid and don't know what this is.
Answer:
x=0
Step-by-step explanation:
"x6" was replaced by "x^6".
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :7x-(5y*x^6)=0
7x - 5x6y = 0
7x - 5x6y = -x • (5x5y - 7)
-x • (5x5y - 7) = 0 Hope this helps and you are not stupid everybody has at least something that they dont understand :)))
