A single triangle is 180 degrees.
As you can see. Triangle A, as it is shown in the bad drawing. It is an isosceles triangle because two sides are equal to one another, indicated with the lines. Angle A is given as 57. By the isosceles triangle theorem, Angle A equals to Angle B. Calculating the missing angle: 180 - 57 (given) - 57 (because of the isosceles triangle theorem type of thing. I forgot) = 66
You can see it is a verticle angle so angle C is equal to angle D, therefore angle D is 66.
Again it is an isosceles triangle so Angle F is 66. 180 - 66(angle D) - 66(angle F) = 48 = angle x
Angle A = 57 degrees. Given
Angle A = Angle B. isosceles triangle theorem
Angle B = 57 degrees. Substitute
Angle A + Angle B + Angle C = 180. Definition of Triangle (I forgot what it was called)
57 + 57 + Angle C = 180. Substitution
Angle C = 66. Subtraction
Angle C = Angle D. Verticle angle theorem.
Angle D = 66. Substitution
Angle F = Angle D. isosceles triangle theorem
Angle F = 66. Substitution
Angle D + Angle F + Angle X = 180. Definition of Triangle?
66 + 66 + Angle X = 180. Substitution
Angle X = 48. Subtraction

Answer:
1. = station A
because 15 gallons = 0.75 discount at B but station A has a 1.50 discount at 15 gallons
Step-by-step explanation:
2. for satation B you have to read the graph
but for station A it is unclear on the graph
a way to work it out is that you know that 10= 1.00 so 12 = 1.2
( divide 12 by 10 )
station B = discount for 12 gallons = 0.6
but Station A = discount for 12 gallons = 1.2
the difference is
1.2 - 0.6 = 0.6 discount

Step-by-step explanation:
Answer:
Hint(look at the first number in each part and math it with the first number in each answer.) For example, 3(937), the distributive property for that one would be 3(900) + 3(30) + 3(7). Then for 5(209) it would be 5(200) + 5(0) + 5(9), then for 6(342), it would be 6(300) + 6(40) + 6(2). Then for 9(821), it would be 9(800) + 9(20) + 9(1), and for the last one it would be 11(143), it would be 11(140) + 11(40) + 11(3). You basically distribute each amount into different place values.

Using the digits 1 to 9 at most one time each fill in the boxes to create an equation that has a negative solution

Answers
Answer:
[4]x+[8]=[1×]+2
Step-by-step explanation:
x will be negative now that the more x you have the higher your number will have to be.
The requried, x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution as x = -3.5.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
One possible solution is,
[1]x + [2] = [3]x + [9]
To see that this equation has a negative solution, we can rearrange it to get:
x + 2 = 3x + 9
x - 3x = 9 - 2
-2x = 7
x = -3.5
Since x is negative, the left-hand side of the equation is positive, but the right-hand side is negative, so the equation has a negative solution.

Answers
Answer:
2 sides are [tex]\frac{33}{13}[/tex] or 2.5
2 sides are [tex]\frac{47}{13}[/tex] or 3.6
Step-by-step explanation:
There must be 2 2x+3s and 2 3x+2s
The perimeter is the sum of the sides (it has 4 sides)
2(2x+3) + 2(3x+2) = 4(4x-5)
distributive property
2*2x + 2*3
4x+6
other one
2*3x + 2*2
6x+4
perimeter
4*4x + 4*-5
16x-20
together...
(4x+6) + (6x+4) = 16x-20
add like terms
10x+10 = 16x-20
add 20 to both sides
10x+30 = 16x
subtract 10x from both sides
30 = 26x
divide by 26 on both sides
[tex]\frac{30}{26} = x[/tex]
simplify
[tex]\frac{15}{13}[/tex]
Substitute the x value
2 of the sides are 2x+3
so
[tex]2(\frac{15}{13} ) + 3[/tex]
[tex]\frac{30}{13} + \frac{3}{1}[/tex]
[tex]\frac{33}{13}[/tex]

[tex]3(\frac{15}{13} ) + 2[/tex]
[tex]\frac{45}{13} + \frac{2}{1}[/tex]

7x + 2y = –1
7x + 2y = 1
14x + 4y = –1
14x + 4y = 1
Answers
Answer:
7x + 2y = 1
Step-by-step explanation:
1. Find the slope of the line.
(y2-y1)/(x2-x1) ----> (11 - (-3))/((-3) -1) ----> (11+3)/ (-3 -1) ----> 14/-4
*lets simplify into (7/-2)*
2. Write into slope intercept form.
y=mx+b (m is the slope) (b is the y intercept)
y = (7/-2)x + b
We now need to find the value of b, this can be done by plugging in values of x and y, and using algebra to solve.
11 = (7/-2)(-3) + b
11 = 10.5 + b
b = 0.5 or 1/2
slope intercept form y = (7/-2)x + 1/2
Now we convert to standard form: ax+by=c
*In this form we our a term cannot be a fraction nor can it be negative*
1. Get x and y on the same side, and since our x term is negative right now, we can make it positive by adding it on both sides.
(7/2)x + y = 1/2
2. We now want to get rid of the fraction in term a, so we multiply the entire function by two, so the denominator cancels out.
2(7/2)x + 2y = 2(1/2)
Simplify and you get
7x + 2y = 1

Answers
Answer:
A
Step-by-step explanation:
The entire circle has an area of pi * r^2
r = 10
pi = 3.14
Area = 3.14 * 10^2
Area = 314 cm^2
But that is the whole circle. What is shaded is 1/4 of the circle which 314/4
which = 78.5 cm^2
Answer: A
Answer:
A) 78.5 cm^2
Step-by-step explanation:
1. To find the shaded part of the circle (1/4), we can use a formula similar to the one we use to find the area of a whole circle, but in this case, for the 1/4 part that's shaded: [tex]\frac{1}{4} \pi r^2[/tex]. Keep in mind that pi is approximated to 3.14.
2. (Solving)
Step 1: Plug in the values.
[tex]\frac{1}{4}(3.14)(10^2)[/tex]Step 2: Simplify.
[tex]\frac{1}{4}(3.14)(100)[/tex] [tex]0.785(100)[/tex] [tex]78.5[/tex] 78.5 cm^2Therefore, the answer is A) 78.5 cm^2.
