8x + 5x what is it simplify
Answer:
13x
Step-by-step explanation:
you would just add the 2 numbers together and then keep the variable. if you know the variable (if there’s a sheet to go off of) then multiply and add but otherwise it’s just 8 + 5 then add an x. 13x
=====================================================
Explanation:
x is a placeholder for a number. Think of it like a box holding a number. Conveniently, the letter 'x' is in the word 'box', so its naturally fitting to use x here.
Writing 8x could represent the idea of us having 8 boxes that are identical. Adding on 5x means we add on 5 more boxes. This leads to 8+5 = 13 boxes in total.
This is one way to see how 8x+5x = 13x
Another way is to write it like this: 8x+5x = (8+5)x = (13)x = 13x. I used the distributive property here.
Combining these terms is possible because 8x and 5x are like terms. They have the same variable and same exponent. We're adding two of the same type of object together.

-6 + -8 10 points plz help
Answer
The answer is negative 14.
Step-by-step explanation:
When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

What is 3/4 x 6 , simplified .
Answer:
9/2
Step-by-step explanation:
3/4 x 6 can be thought of as multiplying 3/4 x 6/1
When multiplying fractions, multiply the numerator (top number) with the numerator, and the denominator with the denominator.
3/4 x 6/1 = (3x6)/(4x1)
3/4 x 6/1 = (18)/(4)
3/4 x 6/1 = 9/2

Answer:
-7/12
Step-by-step explanation:
Answer:
-7/12
Step-by-step explanation:
-1/3 - 1/4 becomes -4/12 - 3/12
this is because 12 is the common denominator for both fractions. then subtract the numerators because when you add or subtract fractions, the denominator stays the same.
-4 - 3 = -7
the answer is
-7/12
the answer cannot be simplified so it remains the same
What is the value for A? What is the value for B? What is the value for C? What is the value for D?
Step-by-step explanation:
step 1. we must assume the ratio of flour to sugar is 2:1.
step 2. A = 2(3/4) = 3/2 1-1/2.
step 3. B = 1-3/4(1/2) = 7/4(1/2) = 7/8
step 4. C = 1(2) = 2
step 5. D = 2-1/2(1/2) = 5/2(1/2) = 5/4 = 1-1/4.

What would be the best method to solve
the system of equations below?
6x + 3y = 21
2x – 3y = -13
Elimination method is the best method to solve the system of equations below
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given system of equations
6x + 3y = 21...(1)
2x – 3y = -13...(2)
Add equations (1) and (2)
6x+3y+2x-3y=21-13
8x=8
Divide both sides by 8
x=1
Now plug in x value in equation 1
6+3y=21
Subtract 6 from both sides
3y=15
Divide both sides by 3
y=5
By Elimination method we find the values of x and y.
Hence, Elimination method is the best method to solve the system of equations below

(24,−17)? Write your answer in simplest form.
Answer:
-3/4Step-by-step explanation:
Given the coordinates (4, -2) and (24, -17), we are to find the slope of the line passing through the points
Slope = y2-y1/x2-x1
Slope = -17-(-2)/24-4
Slope = -17+2/20
Slope = -15/20
Slope = -3/4
Hence the required slope is -3/4

What is the acceleration of a car that goes from 65 km/s to 125 km/h in 5 seconds?
PLEASE SHOW WORK!
A toy rocket lifts off at an initial velocity of 102 feet per second from a height of 10 feet. The height of the rocket can be modeled by the equation h = – 16t2 + 102t + 10, where ‘t' is the time in seconds. When will the rocket hit to the ground?
Answer:
6.47secs
Step-by-step explanation:
Given the height of the rocket modelled by the equation;
h = – 16t^2 + 102t + 10, where ‘t' is the time in seconds
The rocket will hit the ground at h = 0
Substitute into the equation
– 16t^2 + 102t + 10 = 0
Multiply through by -1
16t^2-102t-10 = 0
t = 102±√(102)²-4(16)(-10)/2(16)
t = 102±√10404+640/32
t = 102±√11044/32
t = 102 ±105.09/32
t = 102+105.09/32
t = 207.09/32
t = 6.47secs
Hence it will take 6.47secs for the rocket to hit the ground
Use the following function rule to find f(12). f(x)=10x-4, f(12)=
f(x)=10x-4, f(12)= 116
The value of the function f(x) = 10x - 2 at f(12) is 114.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function f(x) = 10x - 4.
To find f(12) we have to replace x with 12 in the function f(x).
∴ f(12) = 10(12) - 4.
f(12) = 120 - 4.
f(12) = 114.

Given that f(x) = x + 3/2
a) Find f(2)
b) Find f^-1(x)
c) Find f^-1(12)
Step-by-step explanation:
f(x) = x + 3/ 2
For a
f(2) = 2 + 3 / 2
= ( 4 + 3 ) /2
= 7/2
For b
f(x) = x + 3/2
f^-1(x) = ?
Let y = f(x)
y = x + 3/2
Interchanging the roles of x and y we get,
x = y + 3 / 2
y = x - 3 / 2
Therefore f^-1(x) = x - 3 / 2
For c)
f ^ -1(12) = 12 - 3 / 2
= (24 - 3) / 2
= 21 / 2
