Answer:
-3n-4n = 25 + 17
-7n = 42
n= -6
the main thing for here is to combine the like terms and to solve for n which is done by putting all the numbers with variables on one side and the non variables on the other and divide each side by the number that has the variable. Remember that when you bring numbers on the other side, you change its sign, for example if you have 5 on one side and you bring to the other side of the equal sign it becomes -5.
-15 + 15d -7.5d =7.5
15d - 7.5d = 7.5 + 15
7.5d = 22.5
d = 3
for the part where theres 7.5(2d-1)
you multiply each number inside the bracket by 7.5, its called distributivity of multiplication
hope that answers your question
hope you understand what i wrote lol
good luck:)
Answer:
Question 1
Original Equation:
-3n-4n-17=25
Add 17 to both sides (cancels out the -17)
-3n-4n=42
Combine -3n and -4n.
-7n=42
Divide by -7
n = -6
Question 2
Original Equation:
-15+7.5(2d-1)=7.5
Distribute:
-15+15d-7.5=7.5
Add 7.5 to both sides:
-15+15d=15
Add 15 to both sides:
15d=30
Divide by 15:
d = 2

guys im stuck on this and i need helppp
Answer:
Yes and domain is R
Step-by-step explanation:
f(g(x)) = f((2x+1)/x) = 1/(((2x+1)/x)-2) = 1/(2x+1-2x)/x = x. Yes they are inverse of each other. The domain of the composition is the whole R
If f(x) = -3x - 2
find f(-2) + 9
Answer:
f(-2) + 9 is 19
Step-by-step explanation:
[tex]f(x) = - 3x - 2[/tex]
when x is -9:
[tex]f( - 2) = - 3( - 2) - 2 \\ f( - 2) = 10[/tex]
sum up with 9, f(-2)+9:
[tex]f( - 2) + 9 = 10 + 9 \\ = 19[/tex]

solve by factoring
x^2 -10 = 9x
Answer:
(10,0)(-1,0)
Step-by-step explanation:
x^2 - 9x - 10 = 0
(x - 10)(x + 1) = 0
The two solutions are
x - 10 = 0
x = 10
or
x+1 = 0
x = - 1
Answer:
x=10, x=-1
Step-by-step explanation:
Hi there!
We are given this equation:
x²-10=9x
And we want to solve it by factoring
Factoring is easier to do when all of the terms are on the same side, so let's subtract 9x from both sides
x²-9x-10=0
Now we must think of two numbers that add up to -9, but multiply to get -10
Those numbers are -10 and 1
So factor the polynomial using FOIL:
(x-10)(x+1)=0
Now split and solve via the zero product property:
x-10=0
Add 10 to both sides
x=10
x+1=0
Subtract 1 from both sides
x=-1
Hope this helps!

Step-by-step explanation:
So first you plot the points, then calculate how many units it takes from the point that is Sean’s house to his School. Show your work on that by drawing out your skip counting. Then you plot the rest of the points and fpro this calculation: the distance from Sean’s house to his school+ from his school to the grocery store. Then you calculate the distance (in units! ! ! Which means one box is one unit) : distance from Sean’s house to the school+ from school to the commmunity center. Then two calculations you made above you compare. So whichever one is greater is your answer for part b.

Answer:
Answer is 12 square inches of cloth
Step-by-step explanation:
The area of a parellogram is length x height and so what we need to do is get 1.5 x 8 = 12 inches of cloth. I don't know if your talking about the side length of the parellogram being 8 but if the height is 8 then 12 is your answer :)

Answer:
1 58/100 or 1 29/50 (simplified)
Step-by-step explanation:
you can turn them into decimals
5/10 = 0.5

0.5 + 0.08 = 0.58
0.58 = 58/100 = 29/50
Solve the following equations:
4 1/5 ÷ 1 1/5 = 11 - 1 7/18x
The solution of given equation is 5.04.
To find the solution of given equation.
What is algebra?A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given that:
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
4 1/5 ÷ 1 1/5 = 11 - 1 7/18x
convert into simple fraction form, we get
21/5 ÷ 11/5=11-17x/18
convert divide into multiply
21/5*5/11=11-17x/18
cancel out 5 from numerator and denominator, we get
21/11=11-17x/18
same form are in same side
17x/18=11-21/11
after simply, we get
17x/18=121-21/11
17x/18=100/21
cross multiplication on both sides and find x,we get
x=100*18/21*17
x=5.04
So, the solution of given equation is 5.04.

If g(x) = 1 - ¾ x
find: -5g(4) - 1
Answer:
-5g(4) - 1 is 9
Step-by-step explanation:
[tex]g(x) = 1 - \frac{3}{4} x[/tex]
when x is 4:
[tex]g(4) = 1 - \frac{3}{4} \times 4 \\ = 1 - 3 \\ = - 2[/tex]
therefore:
[tex] - 5g(4) - 1 = - 5( - 2) - 1 \\ = 10 - 1 \\ = 9[/tex]
Answer:
9
Step-by-step explanation:
g(x) = 1 - ¾ x
-5g(4) - 1
First find g(4) = 1 - 3/4(4) = 1 - 3 = -2
Then -5(-2) -1 = 10 -1 = 9
