I need help finding X
rotate 270° counterclockwise
Answer:
When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative.

Two less than 3times a number is the same as the number plus 10.
Answer:
6
Step-by-step explanation:
3n - 2 = n + 10. add 2
3n = n + 12 subtract n from both sides
2n = 12. divide by 2
N = 6
The number is 6

gjj h 7/4 to the third power Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.
Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.
Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.
Step 3:
Combine like terms: (18 + 24) squared = 30 squared.
Step 4:
Evaluate each side: 1764 not-equals 900.
Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?
The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.
The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.
The triangle is not a right triangle, but in step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

5) The school that Lexy goes to is selling tickets to the annual talent show. On the first day
of ticket sales the school sold 14 adult tickets and 11 student tickets for a total of $128. The
school took in $88 on the second day by selling 14 adult tickets and 1 student ticket. What
is the price of each adult ticket and student ticket?
$6.00 for adult tickets and $4,00 for student tickets
how do you work it out
Answer:
Adult ticket is $6
Student ticket is $4, as you said.
Step-by-step explanation:
We'll call adult tickets x and student tix y.
14x + 11y = 128
14x + y = 88
First, solve the second equation for y in terms of x:
y = 88- 14x
Then substitute that for y into the first equation:
14x + 11(88-14x) = 128
14x + 968 - 154x = 128
-140x = -840
x = 6 The adult ticket is $6, like you said.
Now take that and solve for y:
y = 88 - 14(6)
y = 88 - 84
y = 4 The student ticket is $4, as you said.
Hope this helps. Feel free to ask questions so you can understand.
how can you get 2 1/2÷5/8
Answer: 4
Step-by-step explanation:
Change the 2.5 to an improper fraction, then multiply by the reciprocal of 5/8.
[tex]2\frac{1}{2} /\frac{5}{8} =\frac{5}{2}*\frac{8}{5}=\frac{40}{10} =4[/tex]
Conversion a mixed number 2 1/
2
to a improper fraction: 2 1/2 = 2 1/
2
= 2 · 2 + 1/
2
= 4 + 1/
2
= 5/

To find new numerator:
a) Multiply the whole number 2 by the denominator 2. Whole number 2 equally 2 * 2/
2
= 4/
2
b) Add the answer from previous step 4 to the numerator 1. New numerator is 4 + 1 = 5
c) Write a previous answer (new numerator 5) over the denominator 2.
Two and one half is five halfs
Divide: 5/

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 5/
8
is 8/

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 10 gives 4/

Find the part. What is 110% of 14.9?
Answer:
16.39
Step-by-step explanation:
Solution 1: You can turn the words into Algebra so What (x) is(=) 1.10 of (multiply)14.9, So x = 1.10 (14.9). x= 16.39
When you see the word what, place an 'x', is means '=', 110% = 1.10
Solution 2: Notice how 100 percent is already 14.9 so 110% should be greater than 14.9, so we're missing another 10%, and 10% of 14.9 is 1.49 just by moving the decimal over. So you would need 14.9 + 1.49 more, so a total of 16.39.
what is the slope help pls?
Answer:
y=7x-6
Step-by-step explanation:
You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say
y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.
