Combine Like Terms:
=−12x+5x
=(−12x+5x)
=−7x
Combining like terms - Combining like terms will simplify a math problem and is also the proper form for writing a polynomial. To combine like terms, just add the coefficients of each like term.

Answer:
60 servings
Step-by-step explanation:
Method 1: 2.5/10 (fraction) = 15/x (fraction)
Draw an arrow from 2.5 to 15 and write x6 (times 6)
Do the same from 10 to x
Then do 10*6 = 60
I don't know another method but hope this helps!
Step-by-step explanation:
First method :-
Using unitary method,
5/2 scoops = 10 servings
1 scoop = 10/5/2 = 4 servings
15 scoops = 15 * 4 = 60 servings
15 scoops = 60 servings of bannock
Second method :-
Using proportions,
Let x be servings of bannock for 15 scoops
Let ratios be 5/2 : 10 and 15 : x
Now,
5/2 : 10 = 15 : x
or, 5/2/10 = 15/x
or, 5/2 * 1/10 = 15/x
or, 1/4 = 15/x
or, x = 15 * 4
so, x = 60
So,
15 scoops = 60 servings of bannock

two six sided dice are rolled and the two dice equals 7. what is the probability that one die is a 3
Let us solve the problem step by step.
here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.
Now, it is time to calculate the probability.
The required probability is,
p = (No. of cases favorable for the event)/(Total no. of cases)
=6/36 = 1/6
Therefore your answer is 1/6.If two six-sided dice are rolled and the two dice are equal. The probability that one die is a 3 will be 6.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
It is given that, two six-sided dice are rolled and the two dice equal 7.
If two dice are rolled. The total no. of possible outcomes will be,
= 6²
=36
The total outcomes are,
(1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
If the desired outcome is their sum which is 7. All the possible cases are 6,
(1,6), (2,5), (3,4), (4,3), (5,2), (6,1)
The required probability is,
p(sum=7) = (No. of cases favorable for the event)/(Total no. of cases)
p(sum=7)=6/36
p(sum=7)= 1/6
Thus, if two six-sided dice are rolled and the two dice are equal. The probability that one die is a 3 will be 6.

In circle T, what is the value of x?
x = 19°
x = 20°
x = 24°
x = 29°
Check the picture below.
Answer:
(a) x° = 19°
Step-by-step explanation:
A triangle inscribed in a semicircle is a right triangle. That means the acute angles in the triangle are complementary:
x° = 90° -71° = 19°
Yes or no is the are of a circle a function of it’s radius
Anything that is a function of something is when that something makes up one side of function as a variable for the entire equation.
So yes the area of a circle is a function of its radius
Answer: Area is a function of the radius, but radius is not a function of the area
Step-by-step explanation:
Since the area of a circle is A = PI^2 , the value of the area depends on the radius, so area is a function of the radius, but not the other way around.

Vance wants to construct a circle tangent to all three sides of the acute, scalene triangle LMN using the following steps.
He will draw altitudes from vertex L and vertex M, and mark their intersection point as O.
He will draw the perpendicular from point O to side MN, and mark the intersection point as P.
He will draw the circle centered at point O which will pass through point P.
Which part of Vance's plan requires revision?
A.
Vance should have found the intersection of two angle bisectors of triangle LMN instead of two altitudes.
B.
Vance should have found the intersection of two perpendicular bisectors of triangle LMN instead of two altitudes.
C.
Vance should have constructed all three altitudes instead of only constructing two altitudes.
D.
Vance should have used the compass to draw a circle through point N instead of point P.
The part that needs revision in the construction of the tangent to the triangle is C. Vance should have constructed all three altitudes instead of only constructing two altitudes.
What is a triangle?A triangle simply means a polygon that has three sides. Also, a triangle has there's edges as well as vertices.
In this case, in order to construct a circle tangent to all three sides of the acute, scalene triangle LMN, it should be noted that the three altitudes have to be taken into consideration.
This wasn't the case in the step given by Vance as only two altitudes were considered. Therefore, this should be the change that is required.

Answer:
c = 0.50(0.48)(1525)
Step-by-step explanation:
If 52% of the students are female, then
100% - 52% = 48% of the students are male
48% = 48/100 = 0.48
To find the number of students who are male:
⇒ total number of students x 0.48 = 0.48 x 1525
Half = 50% = 50/100 = 0.50
⇒ half of the male students = 0.50 x 0.48 x 1525
Solution: c = 0.50(0.48)(1525)

1)By the Triangle Inequality Theorem which set of side lengths could create a triangle?A) 5, 10, 4B) 5, 7, 13C) 7, 9, 3D) 10, 4, 5
Answer:
C
Step-by-step explanation:
The answer is C because it is the only one where any combination of 2 sides will add up to be greater than the other sides.
Answer:
Step-by-step explanation:
A is not possible, because 5 + 4 < 10 (doesn't satisfly inequality.)
B is also not possible => 5 + 7 < 13 (doesn't satisfy inequality.)
D is also not possible => 4 + 5 < 10 (doesn't satisfy inequality)
So, the answer is C, cause the sum of 2 sides is always more than the other one.
Amy now earns $9.50 per hour. This is 125% of
what she earned last year. What did she earn per
hour last year?

The derivative of cosec x² is [tex]-2x.cot \ x^{2} .cosec \ x^{2}[/tex]
DifferentiationFrom the question, we are to differentiate cosec x²
Let y = cosec x², then we will determine the value of [tex]\frac{dy}{dx}[/tex]
[tex]y = cosec \ x^{2}[/tex]
Let [tex]u = x^{2}[/tex]
Then,
[tex]\frac{du}{dx}=2x[/tex]
Also, [tex]y = cosec \ x^{2}[/tex] becomes
[tex]y = cosec \ u[/tex]
Then,
[tex]\frac{dy}{du} = - cot \ u . cosec \ u[/tex]
From Chain rule
[tex]\frac{dy}{dx} = \frac{dy}{du}\times \frac{du}{dx}[/tex]
∴ [tex]\frac{dy}{dx} = -cot \ u.cosec \ u \times 2x[/tex]
Recall that [tex]u = x^{2}[/tex]
Then,
[tex]\frac{dy}{dx} = -cot \ x^{2} .cosec \ x^{2} \times 2x[/tex]
[tex]\frac{dy}{dx} = -2x.cot \ x^{2} .cosec \ x^{2}[/tex]
Hence, the derivative of cosec x² is [tex]-2x.cot \ x^{2} .cosec \ x^{2}[/tex]

By looking at the graph, we can see that the minimum is y = -6.
How to find the minimum value of a function?
The minimum of a function is the smallest value that f(x) takes, to see it, we need to find the lowest value of f(x) in the graph.
In this case, the minimum would be the value that the function takes in the troughs, which we can see is equal to -6.
Then we can conclude that the minimum of the function is y = -6

19 = y
Step-by-step explanation:
Hello!
These angles are vertical angles or angles that are formed by two lines that intersect. The two non-adjacent angles that are formed are congruent and known as Vertical Angles.
Now that we know what vertical angles are, we know that these two angles (19° and y) are congruent because they are formed by the intersection of two lines and are non-adjacent.
19 = y is your answer
