Solve 3x−y=6;y=x−4
Steps:
I will try to solve your system of equations.
y=x−4;3x−y=6
Step: Solvey=x−4for y:
Step: Substitutex−4foryin3x−y=6:
3x−y=6
3x−(x−4)=6
2x+4=6(Simplify both sides of the equation)
2x+4+−4=6+−4(Add -4 to both sides)
2x=2
2x
2
=
2
2
(Divide both sides by 2)
x=1
Step: Substitute1forxiny=x−4:
y=x−4
y=1−4
y=−3(Simplify both sides of the equation)
Answer:
y=−3 and x=1

The admission fee at a county fair is $2 for children and $4 dollars for adults. Suppose that on the last day, 1600 people enter the fair and $5000 is collected. Choose the two equations that can be solved as a system of equations to determine how many children and how many adults attended the fair.
1.) a-c=1600
2.) 4a+2c=5000
3.) 4a-2c=5000
4.) a+c=1600

Answer: 40
Step-by-step explanation: the reason why is that there's a 50/50 chance that it could land on heads or tails.
Answer:
40
Step-by-step explanation:
A coin has a 1/2 chance to land on both heads and tails sides (50/50), so cut 80 in half (80/2), and you get 40.

Answer:
x = 118
Step-by-step explanation:
62° + x° = 180°
x = 180° - 62°
x = 118°
#CMIIWAnswer: 118
both angles have a sum of 180
so if you subtract 62 from 180 then you get 118
the measure of the bigger angle.
Always remember if the angles are attached to a straight line and are only attached to the top or bottom, not both they have a sum of 180.
Here is a diagram that represents (3.1) ⋅ (1.4).
What is the area of rectangle A?
What is the area of rectangle B?
What is the area of the outer rectangle which measures 3.1 units by 1.4 units?
Step-by-step explanation:
1. solution,
length of rectangle A(l)=3.1units
breadth of rectangle A(b)=1units
now,
area of rectangle A=l×b
=3.1units×1units
=3.1 sq units
2.solution,
length of rectangle B(l)=3.1units
breadth of rectangle B (b)=0.4units
now,
area of rectangleB=l×b
=3.1units×0.4units
=1.24 sq units
3.solution,
length=3.1units
breadth=1.4units
area =lxb
=3.1units x 1.4units
=4.34units
Answer:
1) 3.1 2) 1.24 C) 4.34
Step-by-step explanation:
Area = l(w)
Area of rectangle A:
3.1 * 1 = 3.1
Area of rectangle B:
0.4 * 3.1 = 1.24
Both rectangles put together:
First, let's add 1 to 0.4... 1.4
1.4 * 3.1 = 4.34

One pizza was cut into 12 pieces. Eddie ate 1/12 and Melanie ate 1/12. Mom ate 1/6 and dad ate 1/4. Albert ate 1/6 of the pizza. How much, if any, was leftover?
A) 2/6
B) 2/3
C) 4/6
D) 1/2
Answer:
I thinks it's A
Step-by-step explanation:
1) 12:6×1=2
2) 12:4×1=3
3) 1+1+2+3+2=9
4) 12-9=3
The amount of pizza that is left over will be 1/4. Then the correct option is E.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
One pizza was cut into 12 pieces. Eddie ate 1/12 and Melanie ate 1/12. Mom ate 1/6 and dad ate 1/4. Albert ate 1/6 of the pizza.
Then the amount of pizza that leftover will be
⇒ 1 - (1/12) - (1/12) - (1/6) - (1/4) - (1/6)
⇒ 1 - (1/12) - (1/12) - (2/12) - (3/12) - (2/12)
⇒ 1 - [(1 + 1 + 2 + 3 + 2) / 12]
⇒ 12 / 12 - 9 / 12
⇒ (12 - 9) / 12
⇒ 3 / 12
⇒ 1/4
The amount of pizza that is left over will be 1/4. Then the correct option is E.

First we need to find the perimiter of a parallelogram
Side A is the slanted line,
Side B is the 2 horizontal lines.
The equation for this is 2(a+b)
Let's plug in the measurements:
2(18+27) =
2(45) =
90
So the parallelogram is 90 now we have the perimeter of the semi cirlce already which is 18
90 + 18 = 108
