Answer:
f(x) = expression
f(2) = 14 means that your x-value is 2. when you plug in 2 for x, you get 14 as y.
Four boys, Kurt, Marcus, Nathaniel, and Steven, all collect baseball cards. They recently met to show each other some of the cards they had collected. Each boy brought a different amount of cards with them. Nathaniel brought twice as many as Steven, Marcus had four less than Nathaniel, but one more than Kurt. All together, they have 47 cars. How many cars did Kurt bring?
Steven's cards = x
Nathaniel's cards = 2x
Marcus' cards = 2x - 4
Kurt's cards = 2x - 5
Since the sum of the cards is equal to 47, let's set all the cards equal to 47
x + 2x + 2x - 4 + 2x - 5 = 47
Combine like terms.
7x - 9 = 47
Add 9 to both sides
7x = 56
Divide both sides by 7
x = 8
Let's plug 8 into x for Kurt's cards.
Kurt's cards = 2x - 5 = 2(8) - 5 = 16 - 5 = 11 cards.
How can u tell that 7.360 and 7.36 are equivalent decimals
Answer:
You can tell 7.360 and 7.36 are equivalent decimals because when you put a zero in the decimal places, it doesn't count as a number and it doesn't have a value. In conclusion, zero is just a placeholder. Therefore, if you have the zero or not it doesn't matter.

Answer:
The sweat chloride reference value is less than 30 mmol/L. A value of more than 60 mmol/L of chloride in the sweat is consistent with a diagnosis of cystic fibrosis. The values of 30-60 mEq/L may represent heterozygous carriers, these carriers cannot be accurately identified with a sweat chloride test.

There are 28 butterflies in the garden. Some are blue and some are yellow. If b represents the number of blue butterflies in the garden, which expression represents the number of yellow butterflies in the garden?
Answer:
y = 28 - b
Step-by-step explanation:
you can find the number of yellow butterflies, y, by subtracting the number of blue butterflies, b, from the total number of butterflies which is 28.
Austin started with 26 video games and sold x video games. Caleb started with 40 video games and sold three times as many video games as Austin did. How many video games did Austin sell, given they had the same number of video games left?
Answer:
The answer is 7 video games
Step-by-step explanation:
The number of video games Austin sold will be 4.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Austin started with 26 video games and sold x video games. Caleb started with 40 video games and sold three times as many video games as Austin did.
Let x be the number of video games sold and y be the number of video games left. Then the equations will be
y = 26 - x
y = 40 - 3x
From equations 1 and 2, then we have
26 - x = 40 - 3x
3x - x = 40 - 26
2x = 14
x = 4
The number of video games Austin sold will be 4.

An active sphagnum bog deposits a depth of about 1
metre of peat per 1000 years. Roughly how many millimetres is that per
day?
A) 0.0003
B) 0.003
C) 0.03
D) 0.3
E) 3
Answer:
B) 0.003
Step-by-step explanation:
1 meter per 1000 years is 1 mm per year, so 1/365 mm per day.
1/365 mm/day ≈ 0.00274 mm/day ≈ 0.003 mm/day
Answer:
B) 0.003

2.)Solve for Y
3.)Solve for G
5.)Solve for B
6.)Solve for D
Answer:
See below
Step-by-step explanation:
2) x =5y Solve for y
Divide both sides by y
x/5 = y
3) f/g = h Solve for G
Multiply both sides by g
(g/1) f/g =h(g)
f =hg
Divide by h
f/h = g
5) bf = m Solve for b
divide both sides by f
bf/f = m/f
b = m/f
6) 8 = b/d solve for d
Multiply both sides by d
8 ( d) = b
Divide by 8
d = b/8
Harry and Jenny are going to the movies. They each bought a medium popcorn, and Harry got a small soft drink. Jenny had a $4 coupon as a discount, and Harry paid the rest, which came to $23. A movie ticket costs $8, and a medium popcorn costs $4.50. What was the cost for a soft drink?
Answer:
2$
Step-by-step explanation:
2 medium popcorns = 9$
2 Movie tickets = 16$
One coupon = -4$
This is equal to the cost without the soft drink(21$)
23$ - 21$ = 2$
Answer:
$2
Step-by-step explanation:
It was originally $27 but, Jenny used a $4 coupon. Each movie ticket costs $8, each popcorn cost $4.50.
1. Start from the cost of each item.
8+8=16 (cost of the tickets)4.50+4.50=9 (cost of the popcorn) .2. Add the totals together.
16+9+ 25
Now subtract 25 from the original amount.
27-25=2
It costs 2 dollars for a soft drink.

What is the measure of angle TRV?
How do you solve this ? Please !!!
Answer:
m[tex] \angle[/tex]6 = 68°Step-by-step explanation:
From the question all the angles are on a a straight line which means the sum of their angles is 180 and one of the angles is 90°
So to find m [tex] \angle[/tex] 6 , add
m [tex] \angle[/tex] 5 and 90 and subtract the result from 180°
That's
m[tex] \angle[/tex]5 + m[tex] \angle[/tex]6 + 90 = 180
m[tex] \angle[/tex]6 = 180 - 90 - m[tex] \angle[/tex]5
m[tex] \angle[/tex]6 = 180 - 90 - 22
We have the final answer as
m[tex] \angle[/tex]6 = 68°Hope this helps you
In the question, a lines & angles diagram is provided, and we can see three angles labelled here. The angles are angle 5, angle 6 and a 90°.
GiveN,
Angle 5 = 22°One of them is 90°We have to find the measure of the missing angle 6...
All the three angles are lying on a staright line, so their collective measure or the sum of these 3 angles is equals to 180°.
➝ Angle 5 + Angle 6 + 90° = 180°
➝ 22° + Angle 6 + 90° = 180°
➝ Angle 6 + 112° = 180°
➝ Angle 6 = 68°
So, the measure of Angle 6:

-8(-x - 7) = 120
I forgot how to do equations pls help
Answer:
x = 8
Step-by-step explanation:
Given
- 8(- x - 7) = 120 ( divide both sides by - 8 )
- x - 7 = - 15 ( add 7 to both sides )
- x = - 8 ( multiply both sides by - 1 )
x = 8
The angle measurements in the diagram are represented by the following expressions.
A= 5x - 15°
B = 2x + 21°
Solve for x and then find the measure of
Answer:
45°
Step-by-step explanation:
A and B are Alternate exterior angles and congruent, thus
5x - 15 = 2x + 21 ( subtract 2x from both sides )
3x - 15 = 21 ( add 15 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12
Thus
∠ A = 5x - 15 = 5(12) - 15 = 60 - 15 = 45°
∠ B = 2x + 21 = 2(12) + 21 = 24 + 21 = 45°

If A is an odd integer and B is an odd integer, is A*B sometimes, always, or never odd? Explain
Answer:
Always
Step-by-step explanation:
In order for an integer to be even, one of the factors must be 2. Otherwise, it is odd.
If A is an odd number, it does not have a factor of 2.
If B is an odd number, it also does not have a factor of 2.
Therefore, AB also does not have a factor of 2, so it is always odd.
