Answer:
5 nails and 4 screws
Step-by-step explanation:
Make it into an expression where N= amount of nails bought and S= amount of screws bought. Then set it equal to the amount he paid.
ie: 2n+1s=14
Now make another equation for how many he bought.\
ie: n+s=9
Now subtract one of the letter variables from the second equation to get one on alone.
ie: n=9-s
Now, since you have a value for N, substitute it for the value in the original equation so that there's only one variable.
ie: 2(9-s)+1s=14
Now solve for S.
ie: 18-2s+s=14
ie: -s=-4
ie: s=4
Now you have a number value for S that you can plug in the original equation to find the value of N.
ie: 2n+4=14
ie: 2n=10
ie: n=5
Now plug in your values for N and S into the original equation to check it. Your answer is 5 nails and 4 screws.

Find the domain of fg f(x)=x+2 g(x)=1/x+2
A. All real numbers
B. All real numbers, expect 2
C. All real numbers, except-2
D. (-2,0) U [2,-2)
Answer: A. All real numbers
Step-by-step explanation:
Find fg;
f(x) * g(x) = (x + 2) * ( 1 / x + 2)
= ( x + 2) / (x + 2)
= 1
In giving 1 as the product, the domain of fg is any real number.

A triangular prism and its dimensions are shown in the diagram
What is the total surface area of this triangular prism in square meters?
Answer:
need a thanks
Step-by-step explanation:
Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula A = 1 2 b h is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.
The total surface area of the triangular prism is 240 m².
What is a prism?A prism is a three-dimensional object.
There are triangular prism and rectangular prism.
We have,
The total surface area of a triangular prism.
= Perimeter x length + base x height
= (6 + 6 + 8) x 10 + 8 x 5
= 20 x 10 + 40
= 200 + 40
= 240 m²
Thus,
The total surface area is 240 m².

Solve for m...

..
Answer: The answer is m=300.
Step-by-step explanation: Step 1. Simplify the both sides of the equation:
[tex]\frac{-1}{15}m=-20[/tex].
And step 2. Multiply the both sides by [tex]\frac{15}{(-1)}:[/tex]
[tex](\frac{15}{-1})*(\frac{-1}{15}m)=(\frac{15}{-1})*(-20).[/tex] I hoped this is very helpful, please mark me as brainliest, and happy new year!! :D
Solving for the value of m in the given equation, m / -15 = -20, will give us: m = 300.
How to Solve for a Variable in an Equation?To solve for a variable in an equation, isolate the variable on one side of the equation by performing inverse operations (such as addition, subtraction, multiplication, or division) to both sides until the variable is left alone.
To solve for m in the equation m/-15 = -20, we can isolate m by multiplying both sides of the equation by -15 (the reciprocal of -1/15). This will cancel out the denominator on the left side and give us the value of m.
Step 1: Multiply both sides of the equation by -15:
(-15) * (m/-15) = (-15) * (-20)
Step 2: Simplify:
m = 300
Therefore, the value of m is 300.

A boat traveled 225 miles downstream and back. The trip downstream took 9 hours. The trip
back took 45 hours. Find the speed of the boat in still water and the speed of the current.
Answer:
30 hrs
Step-by-step explanation:
Downstream. In water, the direction along the stream is called downstream.
Upstream. In water, the direction against the stream is called upstream. Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then. Speed downstream = (u + v) km/hr. Speed upstream = (u - v) km/hr

Let x be the number equal to 0.124₅, so that
x = 1•5⁻¹ + 2•5⁻² + 4•5⁻³
Multiply x by 5³ to convert it to a whole number:
5³x = 1•5² + 2•5¹ + 4•5⁰
Convert everything to base 2:
5³ = 125 = 64 + 32 + 16 + 8 + 4 + 1 = 1111101₂
1•5² + 2•5¹ + 4•5⁰ = 25 + 10 + 4 = 39 = 32 + 4 + 1 = 100111₂
Then
1111101₂ x = 100111₂
so that
x = 100111₂ / 1111101₂

Angle A and B are supplementary angles. Angle A measures 45 degrees. What is the measurement of angle B?
Answer:
135
Step-by-step explanation:
Supplementary means both angles equal 180 degrees when combined
180 - 45 = 135
Complementary means both equal 9 degrees when combined
if u think connect the lines of S and it makes and 8 for 180 and C makes 9 for 90
The measurement of the angle B should be considered as the 135 when the Angle A is given.
Calculation of the measurement of angle B:Since
Angle A and B are supplementary angles.
Angle A measures 45 degrees.
So we know that the sum of the supplementary angles is sum upto 180 degrees
So, it can be like
A + B = 180
45 + B = 180
B = 180 - 45
= 135 degrees
hence, The measurement of the angle B should be considered as the 135.

If you divide a polynomial f(x) by the factor (x - 4), the remainder will be equal to f(-4).
true or false ?
Answer:
False
Step-by-step explanation:
Given
Polynomial: f(x)
Divisor: (x - 4)
Required
Determine the remainder
To determine the remainder, we have to equate x - 4 to 0
i.e.
[tex]x - 4 = 0[/tex]
Add 4 to both sides
[tex]x - 4+4 = 0+4[/tex]
[tex]x = 0+4[/tex]
[tex]x = 4[/tex]
Substitute 4 for x in f(x) to get the remainder.
So, f(x) becomes f(4)
The result of f(4) is the remainder f(x) when divided by x - 4
Hence, the statement is false.

On a field trip, there are 3 chaperones for every 20 students. There are 92 people on the trip. Answer these questions. If you get stuck, consider using a tape diagram.
Answer:
I don't really know what the question is but..
Step-by-step explanation:
Since total of 92 people in the trip including student and chaperon, add groups of 23 to become 92 or use this equation
(20+3)xy=92
23y=92
y=92/23
y=4
therefore,
20x4=80 (students)
3x4=12 (chaperons)
Answer:
15 chaperones
Step-by-step explanation:
1. Okay, First you're going to see how many times 20 can feet into 92. Which is 4.5 times. However, you cannot cut someone in half. So the answer would actually be 5. Then. Just do 5*3, because remember, there are THREE chaperones for every 20 students.
