Answer: x=6
Step-by-step explanation:
-6x+8=4(5-x)
-6x+8=20-4x
12=2x
x=6
Answer:
-6
Step-by-step explanation:
-6x+8=20-4x
subtract 8 from both sides:
-6x+8-8=20-4x-8
simplifiy:
-6x=-4x+12
Add 4x to both sides:
-6x+4x=-4x+12+4x
simplifiy:
-2x=12
divied both sides by -4:
-2x/-2=12/-2
simplifiy:
x=-6

Work out the area of the trapezium.
Answer:
58.29 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (a + b) , substitute given values into formula
A = [tex]\frac{1}{2}[/tex] × 6.7 × (7 + 10.4)
= 3.35 × 17.4
= 58.29 cm²
Some campaigners want a maximum wage. This would be in a ratio of 10:1 with the minimum wage. If the minimum wage is £8.72 an hour for over 25's, what would the maximum wage be
Answer:
The value of the maximum wage is £87.2
Step-by-step explanation:
Here, we want to get the maximum wage given the ratio it has with the minimum wage
To get the value of the maximum wage, we proceed to multiply the value of the minimum wage by 10
Mathematically, that would be;
8.72 * 10 = £87.2

Given :
Given expression is [tex]5p^3 + 45p^2 + 40p[/tex]
Lets factor the given trinomial by factoring out GCF that is greatest common factor
Lets find out GCF from the given expression
all the terms are divisible by 5 and also we have 'p' in common
so GCf is 5p
[tex]5p^3 + 45p^2 + 40p\\5p\left(p^2+9p+8\right)\\[/tex]
Now we factor [tex]\left(p^2+9p+8\right)[/tex]
Product is 8 and sum is 9
So factors are 8 and 1
[tex]5p\left(p^2+9p+8\right)\\5p\left(p+1\right)\left(p+8\right)[/tex]
So the factors are
[tex]5p, p+1, p+8[/tex]

The mean for this set of data is 18. Which number could be put in the blank to make this statement true?
16 10 22 ___
A. 84
B. 24
C. 48
D. 72
The mean of the data is 18 and the missing statement is x = 24
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the data be represented as A
Now , the value of A = 16 , 10 , 22 , x
Let the mean of the data be M = 18
To find the mean of the data set, we need to add up all the numbers and divide by the total number of numbers:
(16 + 10 + 22 + x) / 4 = 18
We can simplify this equation by multiplying both sides by 4 to get rid of the fraction:
16 + 10 + 22 + x = 72
Now we can solve for x by subtracting the three known numbers from both sides:
x = 72 - 16 - 10 - 22
x = 24
Therefore, the number that could be put in the blank to make the statement true is 24

GUYS PLEASE HELP I MARK BRAINLIEST 5 STARS IM SORRY ABOUT THE POINTS I ONLY HAVE 13 Andre’s school orders some new supplies for the chemistry lab. The online store shows a pack of 10 test tubes costs $4 less than a set of nested beakers. In order to fully equip the lab, the school orders 12 sets of beakers and 8 packs of test tubes.
Write an equation that shows the cost of a pack of test tubes, t, in terms of the cost of a set of beakers, b.
t=b-4
The school office receives a bill for the supplies in the amount of $348. Write an equation with t and b that describes this situation.
b+t=348
Since t is in terms of b from the first equation, this expression can be substituted into the second equation where t appears. Write an equation that shows this substitution.
b+(b-4)=348
b=176
How much did the school pay for a set of beakers? $____
How much did the school pay for a pack of test tubes? $____
Answer:
this is not originally by me
Step-by-step explanation:
10t = b - 4
12b+8t = $348
This is a system of equations. I’ll be solving through substitution.
In the first equation. solving for b (the easier variable to isolate) gives you:
b = 10t + 4
Substitute this into the second equation:
12(10t+4) +8t = 348
120t+48+8t = 348
128t = 300
t = 2.34375 —> round it to the nearest cent to get 2.34 dollars
b = 10t+4
b = 10(2.34)+4
b = 27.4 dollars

A similarity transformation consisting of a reflection
and a dilation is performed on a figure, and one point maps to itself. Explain how this can happen.
If the point in question is on the line of reflection, then the point won't move. Any point on a line of reflection stays where it is.
If that same point is the center of dilation, then it also doesn't move. The center of dilation is the only point that doesn't move in a dilation.
So the two conditions are:
The point must be on the line of reflectionThe point must be the center of dilationThese two facts mean that the line of reflection must go through the center of dilation.

If the perimeter of this triangle is 15 centimeters, what is the value of n?
5n - 6
n
2n + 1
Express your answer as a decimal number.
Answer:
25/14
Step-by-step explanation:
The value of n that makes up the triangle of perimeter 15 centimeters is 2.5
How to determine the value of n?The side lengths of the triangle are given as:
5n - 6, n and 2n + 1
The perimeter is given as:
P = 15
The perimeter is the sum of the side lengths.
So, we have:
5n - 6 + n + 2n + 1 = 15
Collect like terms
5n + n + 2n = 15 + 6 - 1
Evaluate the like terms
8n = 20
Divide both sides by 8
n = 2.5
Hence, the value of n that makes up the triangle is 2.5

The Nguyen family is traveling cross-country, driving 300 miles each day. Let 2 represent the number of days in the trip and let y represent the total number
of miles driven.
Write an equation to model their trip.
Enter the correct equation in the box.
Step-by-step explanation:
y = Total number of miles driven
= Number of days * Number of miles per day
= (x) * (300).
Therefore the equation is y = 300x.
When x = 2, y = 300(2) = 600.
The Nguyen family drove 600 miles during the 2 days.
