Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answer:
K=24
B=21
Step-by-step explanation:
x+x-5=43
2x=48
x=24
K=24
B=21
Answer:
24
Step-by-step explanation:
So the only way I think would be possible to get the answer is if you divide 43 by 2 (since Bobbie and Kylie are 2 people) then subtract 5 to get the answer?
help please. find the values of x and y and if you feel like it, show your work
Answer:
[tex]x=4[/tex], [tex]y=61[/tex]
Step-by-step explanation:
Since the triangles are congruent, we already know that they have the same angles and sides.
We can solve for the missing side with this equation:
[tex]51=12x+3[/tex]
subtract [tex]3[/tex] from both sides
[tex]48=12x[/tex]
divide both sides by [tex]12[/tex]
[tex]x = 4[/tex]
Due to the Angle Theorems we already know [tex]2[/tex] of the angles on the triangle:
[tex]63[/tex] and [tex]56[/tex]
We can solve for the missing angle with this equation:
[tex]A+B+C=180[/tex]
[tex]63+56+y=180[/tex]
[tex]119+y=180[/tex]
subtract [tex]119[/tex] from both sides
[tex]y=61[/tex]

find the solution to the following system of equations using substitution or elimination
Answer:
D. (2,-3)
Step-by-step explanation:
if you substitute 2 for the x value and -3 for the y value in both equations, it works out.
instead of y=3x-9 it would be -3=3(2)-9.
you solve and get -3=-3, so it's a solution.
and instead of y=-2x+1 it would be -3=2(2)+1. after solving it, you would get -3=-3 again, so it works for both equations.
is this right as well?
Answer:
yes

True or False: A function must have a different output for each input. A True B False
Answer:
true
Step-by-step explanation:
find the measure of angle b. no fake answers.
Answer:
∠ b = 42°
Step-by-step explanation:
b and 48° form a right angle, then
b = 90° - 48° = 42°
Answer:
42 degrees
Step-by-step explanation:
The angle shared by 48 and b is 90 total degrees.
Subtract 48 from 90 to find the measure of b
Which of the following expressions simplifies to a negative number? Select all that apply.
(-1)(-1)(-1)(-1)
(-1)(-1)
(-1)(-1)(-1)
(-1)(-1)(-1)(-1)(-1)
Answer:
Wait like all of them or some? I think it's 3 and 4.
Step-by-step explanation:
You add the two negative (negative + negative =positive). 3 and 4 have an extra left over which makes one negative, unless I did that wrong
Answer: 3 and 4
Step-by-step explanation:
If it is an odd number of (-1)s then it is negative. if it is an even number of them then it is positive.

please step by step explanation
Answer:
x=-2
Step-by-step explanation:
5x+4=-6 so basically what you want to do is try to get x by itself
step 1 subtract 4 from each side
5x=-10
step 2 divide each side by 5
x=-2

Answers:
Sam's current age = 24The mother's current age = 48=========================================================
Explanation:
s = Sam's age right now
2s = the mother's age right now, since she is twice as old as Sam currently.
In 12 years time, Sam will be s+12 years old.
12 years ago from this current year, the mother was 2s-12 years old.
Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value
Set the expressions equal to one another and solve for s.
s+12 = 2s-12
s-2s = -12-12
-s = -24
s = 24
Sam is currently 24 years old.
His mother is currently 2s = 2*24 = 48 years old.
12 years ago, his mother was 2s-12 = 48-12 = 36 years old.
12 years from now, Sam will be s+12 = 24+12 = 36 years old.
Since we get 36 each time, this confirms we have the correct answers.
What value of n will make this equation correct. 3/10 n = 4/5
Answer:
n =[tex]\frac{5}{10}[/tex]
Step-by-step explanation:
Answer:
n= 2 and two thirds
Step-by-step:
this is the equation
3/10n=4/5
so to get n by itself, you multiply both sides by 10/3. I did 4/5 times 10/3 and I got 2/2/3, or two and two thirds

Definition and description of gravity
Answer:
1. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
2. extreme or alarming importance; seriousness.
"crimes of the utmost gravity"
Step-by-step explanation:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects.

can anyone please help me with question need help please
Step-by-step explanation:
there is no reason in maths only the method
1. If DC is an angle bisector, what is the
measure of DCB?
2. Without constructing, will the incenter lie
inside or outside this triangle? Why or why
not?
Answer:
1.
∠DCB is the half of the measure of ∠ACB as the angle bisector DC cut it in two equal parts.
m∠DCB = 1/2m∠ACB m∠DCB = 1/2(101.31°) = 50.655°2.
The incenter is the intersection of the angle bisectors.
All three angle bisectors lie inside the triangle, hence the incenter is always inside.
Devon draws one marble from a bag containing 5 red, 3 green, and 4 yellow marbles. What is the probability that Devon draws a green marble?
Answer:
3/12 or 1/4 after simplifying
Step-by-step explanation:
3 chances of getting green because there are 3 green and there is a total of 12 marbles so 3 out of 12, which is equal to one fourth.

f(-2) when f(x)=25x-4
Answer:
25x4 - 2
Step-by-step explanation:
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 25 is the square of 5
Check : 2 is not a square !!
