Solve 8x – 5 = 23 + 4x.
Answer: X equals 7
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
First you want to simplify the equation
8x + (-5) = 23 + 4x
-5 + 8x = 23 + 4x
Then solve for x, but before we do that we !!!must!!! move all terms that have x to the left. Everything else would go to the right.
So we add -4x to both sides ..
-5+ 8x + (-4x) = 23 + 4x + (-4x)
-5 + 4x = 23 + 4x + (-4x)
-5 + 4x = 23 +0
-5 + 4x = 23
Then add 5 to both sides of the equation:
-5 + 5 + 4x = 23 + 5
0 + 4x = 23 + 5
4x = 23 + 5
4x = 28
Then divide each side by 4:
x = 7
And there you have it. The answer is 7. Hope this helps! :)

Answer:
a = 6
Step-by-step explanation:
120 = 3 + 3(7a - 3) (by PEDMAS, expand parentheses first by distributive property)
120 = 3 + 7a(3) - 3(3)
120 = 3 + 21a - 9
120 = 21a - 6 (add 6 to both sides and rearrange)
21a = 120 + 6
21a = 126 (divide both sides by 21)
a = 126/21
a = 6
Step-by-step explanation:
120-(3+3*(7*a-3))=0
Step by step solution :

:
-21 • (a - 6) = 0
STEP

:
Equations which are never true:
4.1 Solve : -21 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : a-6 = 0
Add 6 to both sides of the equation :
a = 6
One solution was found :
a = 6

Find a formula for the nth term of the arithmetic sequence a1=-17 a2=-12 a3=-7 a4=-2
Answer:
Step-by-step explanation:
Recursive formula

Explicit formula:
a^n = -17 + (n-1) * 5
Two straight lines have equations y = p x + 4 y = p x + 4 and p y = q x − 7 p y = q x − 7 , where p p and q q are constants. The two lines meet at the point ( 3 , 1 ) ( 3 , 1 ) . What is the value of q q ?
Answer:
q = [tex]\frac{8}{3}[/tex]
Step-by-step explanation:
The point of intersection (3, 1 ) is the solution to both equations
Using
y = qx - 7 and substituting x = 3, y = 1
1 = 3q - 7 ( add 7 to both sides )
8 = 3q ( divide both sides by 3 )
[tex]\frac{8}{3}[/tex] = q

Hello! Some assistance with this question would be really helpful (:
The mode is the most common number in the data set. If there are two numbers that appear frequently (in this case 69 and 73) then this data set has two modes.
The median is the middle of the set of numbers (line them up from top to bottom).
In this case it should look something like:
68 68 69 69 69 69 70 70 71 72 72 73 73 73 73 75 78
If the whole list of numbers are even, then pick the two middle numbers and find their average. If it is odd, just choose the middle most number.
Mean is the average of all numbers. If you have 5 numbers, add them all up and divide by 5. If you have 10 numbers, add them all up and divide by 10.
Shelley's kitten weights 2 1/3 times as much as she did last year. She now weighs 21 ounces. What did the kitten weight a year ago?
Answer:
weight of the kitten last year = 9 ounces
Step-by-step explanation:
Let
x = weight of the kitten last year
Weight of the kitten this year = 2 1/3 * x = 21
7/3*x = 21
7/3x = 21
x = 21 ÷ 7/3
x = 21 × 3/7
= 63/7
x = 9 ounces
weight of the kitten last year = 9 ounces
