Answer:
4x-16
Step-by-step explanation:
When combining like terms you combine the constant terms (the terms without a variable) and the x terms. Since the only variable term is 4x we can leave in at that.
But there are two constant terms -8 and -8, together they make -16 so, the simplified expression would be 4x-16
help please!!
Solve for x.
Answer:
x = 9
Step-by-step explanation:
Theorem:
The measure of an exterior angle of triangle equals the sum of the measures of its two remote interior angles.
The angle measuring 12x + 14 is an exterior angle of the triangle.
The angles measuring 76 deg and 1 + 5x are its remote interior angles.
12x + 14 = 1 + 5x + 76
12x + 14 = 5x + 77
7x = 63
x = 9
If a machine that prints designs on T-shirts prints 500 shirts in 3 hours, how many hours will it take to print designs on 1,800 shirts?
500 shirts / 3 hours = 166 2/3 shirts per hour.
Divide total shirts by shirts per hour:
1800 / 166 2/3 = 10.8 hours.
Question 695271
{{{500/3=1800/x}}}
Cross multiply:
{{{(3*1800)/500}}}
=10.8 hours

I tried my best!!
I dunno how to solve this
Answer:
9
Step-by-step explanation:
First off you need to find the interval that four falls in.
Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one. But four is greater than three and less than ten, so it falls in the second interval.
So, now you can substitute four in for x for the second equation

x/5 - 12 = -8 equals what
Which of the following is the inverse of F(x) = 2x + 3 ?
Explanation:
y=f(x)
y=2x+3
Switch the places of x and y:
x=2y+3
Solve for y:
2y=x−3
y=(x−3)/2
Thus inverse of f(x)= (x-3)/2

A bag with 10 marbles has 2 blue marbles, 4 yellow marbles, and 4 red marbles. A marble is chosen from the bag at random. What is the probability that it is blue? Write your answer as a fraction in simplest form.
Answer:
1/5
Step-by-step explanation:
There are 2 out of 10 that are blue so in fraction form thats 2/10 so when you simplify it, the simplest form is 1/5

(x2+4x+8)+ (2x2 +5x+9)
Answer:
[tex]\left(x^2+4x+8\right)+\left(2x^2+5x+9\right)=3x^2+9x+17[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)[/tex]
solving the expression
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)[/tex]
remove the parentheses
[tex]\left(x^2+4x+8\right)+\:\left(2x^2\:+5x+9\right)=x^2+4x+8+2x^2+5x+9[/tex]
Group like terms
[tex]=x^2+2x^2+4x+5x+8+9[/tex]
Add similar elements: x² + 2x² = 3x²
[tex]=3x^2+4x+5x+8+9[/tex]
Add similar elements: 4x + 5x = 9x
[tex]=3x^2+9x+8+9[/tex]
[tex]=3x^2+9x+17[/tex]
Therefore, we conclude that:
[tex]\left(x^2+4x+8\right)+\left(2x^2+5x+9\right)=3x^2+9x+17[/tex]
You have a bag of 15 marbles. 8 are red. 5 are blue. 2 are green. What is the probability of randomly pulling out a blue marble on the first try?
a. Because it is random, you can't calculate the probability
b.33%
c.3.3%
d.0.3 %
Answer:
33%
Step-by-step explanation:
to find the percentage of the probability you have to divide the number of diff ways of pulling out a blue marble to all the diff ways of pulling a random marble. the blue ones are 5 in total and that many are the diff ways of pulling out one, while all the diff ways of pulling a rando are equal to the total number of marbles, which is 15. so you just have to divide 5/15=1/3, whish is 33.(3)%

In a recent year, 33.8% of all registered doctors were female. If there were 54,300 female registered doctors that year, what was the total number of registered doctors?
Round your answer to the nearest whole number.
Answer:
160 650.88 ( rounds to 160 651)
Step-by-step explanation:
Let n be the total amount of registered doctors that year. Then:
0.338n=54300
n=54300/0.338= 160 650.88 ( rounds to 160 651)

Answer:
so if you put 14 in the boys bubble then do 30-14
Step-by-step explanation:
Answer: 0.5
a) boys: 14
girls : 16
b) the ways to randomly select a student is n(A) = 30C1 = 30
the ways to choose a girl is n(B) = 16C1 = 16
=> the probability to randomly select a student being a girl is
n(B)/n(A) = 16/30 ≈ 0.5

Answer:
y = 3, TU = 6
Step-by-step explanation:
SU is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
[tex]\frac{SV}{ST}[/tex] = [tex]\frac{VU}{TU}[/tex] , substitute values
[tex]\frac{24}{4y-2}[/tex] = [tex]\frac{14.4}{2y}[/tex] ( cross- multiply )
14.4(4y - 2) = 48y
57.6y - 28.8 = 48y ( subtract 48y from both sides )
9.6y - 28.8 = 0 ( add 28.8 to both sides )
9.6y = 28.8 ( divide both sides by 9.6 )
y = 3
Then
TU = 2y = 2 × 3 = 6

Answer:
A. -2[tex]\sqrt{7}[/tex]
Step-by-step explanation:
3 - 5 = -2
The [tex]\sqrt{7}[/tex] is just like an x variable at this point because they are both the same. If it was [tex]\sqrt{7}[/tex] and [tex]\sqrt{14}[/tex] for example, then you wouldn't be able to subtract them so easily. Kinda like how you can't subtract 3x-5y because they're two different variables.
