11Step-by-step explanation:
The sum of interior angles is equal to exterior angle
Given the following
Interior angles = 5x + 10 and 58
Exterior angle 11x+2
According to the postulate:
5x + 10 + 58 = 11x + 2
5x + 68 = 11x + 2
Collect like terms
5x -11x = 2 - 68
-6x = -66
x = -66/-6
x = 11
The value of x is 11
Suppose the expression was (12 - 3)². Would you still simplify 3² first? Explain.
Answer:
No because the 2 is outside of the parentheses meaning it should be 9^2
Step-by-step explanation:
Answer:
No, I will not simplify 3² first.
Rather I would simplify (12-3) first, i.e., 9.
Then simplify 9² which gives the answer 81.
Step-by-step explanation:
(12-3)²= 9²= 81Please help WHAT IS THE PERCENT OF 39.8 out of 200 QUICK PLEASE
Answer:
19.9%
Step-by-step explanation:
39.8/200 = 0.199 (move decimal two times)
19.9%
or you can just see what number get 200 to 100, which is by dividing by 2. What you do to the bottom you do to the top so 39.8/200 (divide both sides by 2) = 19.9/100
which is 19.9%.

Brian goes to schol 6 hours per day, works 4 hours perday, and sleeps for 9 hours per day. What is the ratio of hours Brian works to hours Brian sleeps?
The ratio of hours Brian works to hours Brian sleeps is 4/9.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Brian goes to school 6 hours per day, works 4 hours per day, and sleeps for 9 hours per day.
So, the ratio of hours Brian works to hours Brian sleeps
= 4/ 9
Hence, the ratio is 4/9.

Answer:
(-8) is the missing value here, so
the coordinates will be (-8,8)
Answer:
-8
Step-by-step explanation:
→ Substitute y = 8 into -4x - y = 24
-4x - 8 = 24
→ Add 8 to both sides to isolate -4x
-4x = 32
→ Divide both sides by -4 to isolate x
x = -8

Shasta is going to her best friend's house for dinner. Her mother says she needs to be back in 2 and a half hours. If she leaves at 5:00 pm, what time will she be back?
Answer:
she will be back at 7:30pm
Step-by-step explanation:
From the question we are given
Time that Shasta leaves for her best friend place = 5:00pm
If she is to come back after 2 and a half hour, hence we will have to add 2hr 3ominutes to the time she left to know the time she will be back as shown:
She will be back at 5:00 + 2hr 30min = 7:30pm
Hence she will be back at 7:30pm
What transformation for Rectangle A would result in Rectangle B?
A
reflection across the X-axis
B
reflection across the y-axis
c
translation, 4 units up
D
translation, 2 units down
Answer:
I think A I'm not sure tho
In the transformation of rectangle A, a reflection is across the X-axis. The correct option is A.
What is a reflection?A reflection in mathematics is a mapping from a Euclidean space to itself that is an isometry with a set of fixed points known as the hyperplane, also known as the axis or plane of reflection. The mirror image of a figure in the axis or plane of reflection is the image produced by a reflection.
Given image is having a rectangle A which is having reflection across the X-axis. The meaning of the reflection is that the figure will have an image of itself across the x-axis.
Therefore, in the transformation of rectangle A, a reflection is across the X-axis. The correct option is A.

Suzie solves the equation below:
x2 + 4x - 12 = 2
(x - 2)(x + 6) = 2,
by setting x -2 = 0 and x + 6 = 0.
Her solutions are x = 2 and x = -6.
Is Suzie correct? Why or why not?
Answer:
Suzie's answers are incorrect.
Step-by-step explanation:
x^2+4x-12=2
+12 +12
x^2+4x=14
(if we put Suzie's answer in for x)-
2^2+4(2)=14
4+8=14
Suzie's first answer is incorrect (4+8=12)
Let's try the next one with Suzie's answer
(-6-2)(-6+6)=2
(-8)(0)=2
This answer is also incorrect. (-8*0=0)

Step-by-step explanation: To add or subtract two fraction, you need to find a common denominator. The easiest way to do that is to just multiply the denominators of the two fractions together. 3 x 4 = 12 so I'll use 12 as my common denominator. Now that we have that, we have to convert the numerators. We must multiply the numerators by the same number we multiplied or denominators by to get the common denominator. 3 x 4 = 12, 4 x 3 = 12, 2 x 4 = 8, 3 x 4 = 12. Now the fractions we have are 9/12 and 8/12. Since they have the same denominator now we can add them. 9/12 plus 8/12 equals 17/12 or 1 and 5/12 written as a mixed number. We also add the whole numbers. 1 plus two equals 3. 3 plus 1 and 5/12 equals 4 and 5/12.
