Answer:
Substitution Property
Step-by-step explanation:
So we know that:
[tex]m\angle A=m\angle B[/tex]
And we also know that:
[tex]m\angle A+m\angle C=\angle D[/tex]
And by using a specific property, we get that:
[tex]m\angle B+m\angle C=\angle D[/tex]
Essentially, we substituted B for A.
So, this is an example of the substitution property, where if two sides/angles are congruent, we can substitute them for each other.

Step-by-step explanation:
BASEBALL The formula for a pitcher's earned run average, or ERA, is a = 9r/p. In
this formula, a is the earned run average, r is earned runs, and p is innings pitched.
b. Find the earned runs for a pitcher with an ERA of 2.63 who has pitched
89 innings.
Answer:
To find a baseball pitcher's earned run average you can use the formula EI 9r
To find a baseball pitcher's earned run average (ERA), you can use the formula Ei=9r, where E represents ERA, i represents number of innings pitched, and r represents number of earned runs allowed.
Step-by-step explanation:
9x^2 - 16 = (px+t)(px-t) both p and t are constants. Which of the following could be the value of p
Answer:
p = 3
Step-by-step explanation:
9x² - 16 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b)
Thus
9x² - 16
= (3x)² - 4²
= (3x + 4)(3x - 4)
Compare with (px + t)(px - t)
then p = 3
The sum
as three consicutive
multplies of 11 is
363
there eltiples.
Answer:
Three consecutive multiples are 110,121 and 132 which has the sum of 363. 33C = 363; C = 33, By substituting C = 33 in numbers 11C, 11(C – 1) and 11(C + 1) we get values 110, 121, 132.

3b+4-1b+3 what is the answer please help
Answer:
2b +7
Step-by-step explanation:
We assume you want to simplify this expression. It can be helpful, though is not required, to group like terms near each other.
= 3b -1b +4 +3
= b(3 -1) +(4 +3) . . . combine like terms
= 2b +7
TOPIC: similtaneous linear equations
p1 + 2q = 3,
p - 2q = 3
Answer:
q-0
p-3
Step-by-step explanation:
there are two ways to solve elimination or substitution method I'll use the latter
so take the second equation and find an expression equal to p
p-2q=3
p=2q+3
substitute the above expression in the first equation
(2q+3)1+2q=3
open brackets
2q+3+2q=3
collect like terms
4q+3=3
solve
4q=0
q=0
substitute q in any equation you want I'll choose the second
p-(2×0)=3
p-0=3
p=3
Answer:
p = 3 ; q = 0
Step-by-step explanation:
In this linear pair of eqn. in 2 variables , they have a unique solution i.e. they will have only single solution . We know that
[tex]p + 2q=3[/tex] & also [tex]p -2q=3[/tex] . So, we can also equate them as :-
[tex]p + 2q = p-2q[/tex] (∵ Both the eqn. have 3 in their right hand side product )
Solving the eqn. gives,
[tex]=> 2q + 2q = p-p\\=> 4q=0\\=>q=0[/tex]
Putting the value of q in any one of the linear eqn gives ,
[tex]p+2q=3\\=> p+2(0)=3\\=>p+0=3\\=>p=3[/tex]

If f(x) = x2 + 4x - 12, find f(2).
Answer:
-3
Step-by-step explanation:
Please write this as f(x) = x^2 + 4x - 12. "x^2" represents "the square of x."
f(2) is the value of this function when x = 2:
f(2) = f(2) = (2)^2 + 4(2) - 12 = 9 - 12 = -3

What is the factored form of this expression? 5p^3-10p^2+3p-6
Answer:
[tex](5p^2+3)(p-2)[/tex]
Step-by-step explanation:
In this problem, we need to write the factor form of expression [tex]5p^3-10p^2+3p-6[/tex].
It can be done as follows :
[tex]5p^3-10p^2+3p-6=(5p^3+3p)+(-10p^2-6)[/tex]
Taking common form the terms as follows :
[tex]=p(5p^2+3)-2(5p^2+3)[/tex]
It can be also written as :
[tex]=(5p^2+3)(p-2)[/tex]
Hence, the factored form of [tex]5p^3-10p^2+3p-6[/tex] is [tex](5p^2+3)(p-2)[/tex]
Answer: (p-2)(5p^2+3)

Answer:
38.81%
Step-by-step explanation:
Circle area = п r ²
п = 3.14
r = 4 cm
Circle area = 3.14 * (4cm)²
Circle area = 3.14* 16cm²
Circle area = 50.24cm²
Triangle area = (heigth*width)/2
heigth = 2.5 + 4 = 6.5cm
width = 3 + 3 = 6cm
triangle area = (6.5cm*6cm)/2
triangle area = 39cm²/2
triangle area = 19.5cm²
then:
the probability that a randonly select point whitin the circle falls in the shaded area is:
19.5/50.24 = 0.3881 (aprox)
0.3881*100 = 38.81%

Step-by-step explanation:
(a)

We need to perform a multiplication.
The following rule is applied:
In our example, the factors in the new numerator are:
, ,
Notice that all non-fraction factors are placed in the numerator.
The only factor in the new denominator is: 2.
We need to get rid of all the denominators in this equation.
This can be achieved by multiplying both the left and the right side by the Least Common Denominator.
In our example, the LCD is equal to 2.

I'm working with varibles on both sides. This is math, also algebra 1. The expression is... 8-4a=16-8a I'm so confused on which side to subtract from. I tried doing +8 on both sides. Please help.
Answer:
a=2
Step-by-step explanation:
You can have "a" on both sides and still get an answer easily. You start off by adding 8a to the right. That makes 8+4a=16. You then subtract 8 from 16 and get 4a=8. Divide by 4 to get your answer. You get a=2
