solve for x 6(4x+1)=78
Answer:
x=3
Step-by-step explanation:
here,
6(4x+1)=78
or,24x+6=78
or,24x=78-6
or,24x=72
or, x=72/24or, x=3SO, THE ANSWER IS: 3.For every pound a company spends on advertising, it spends £0.26 on its website. Express the amount spent on advertising to the amount spent on its website as a ratio in its simplest form.

When solving the inequality 3x - 2 < 8x + 10, the next line
becomes 3x < 8x + 12. Which property justifies this step?

(2) Associative
(3) Multiplicative Property of Equality
(4) Additive Property of Equality
The measure of one angle is thirteen less than five times the measure of another angle. The sum of the measures of the two angles is 140°. Determine the measure of each angle in degrees.
Answer:
The two angles are 25.5 and 114.5
Step-by-step explanation:
x = measure of one angle
5x - 13 = measure of the other angle {one angle is 13 less than 5 times the other}
x + 5x - 13 = 140 {sum of the two angles is 140}
6x - 13 = 140 {combined like terms}
6x = 153 {added 13 to each side}
x = 25.5 {divided each side by 6}
5x - 13 = 114.5 {substituted 25.5, in for x, into 5x - 13}
2x + 12 = 2(x+8)-4

Find an equation of the line that contains the point (4,-3) and is perpendicular to the line 2x-3y=4
HELPPPPPPPPPP PLISSSSSSSS
Answer:
Step-by-step explanation:
-3y = -2x + 4
3y = 2x - 4
y = 2/3x - 4/3
perp; -3/2
y + 3 = -3/2(x - 4)
y + 3 = -3/2x + 6

9+3+6+7 = 25
5+5+4+9 = 23
6+8+4+? = 24 ? = 6
Decide whether n = 9 is a solution to
the equation 2+n=7. Write yes or no
Answer:
No. The answer would be n=5
Step-by-step explanation:
You have to subtract the 2 from both sides to cancel it out on the left side. so you would be doing 7-2, not 7+2

3x+10=16
Select the expression that shows the application of the distributive property for
9(t - 5)
a
9t + 14
b
9 + t + 9 + 5
c
9t + 45
d
9t - 45
PLEASE HELP ME!!!
Answer:
c. 9t+45 that shows distributive property
where it shows a*(b+c)=(a*b)+(b*c).so,9(t+5)=9*t+9*5

Just carpet has eight different quality grades of carpeting. Three types are being selected for a corporate test on durability. how many different samples of size 3 can be taken without replacement? how many different samples of size 5 can be taken without replacement?
Answer:
When we have a set of N elements, the number of combinations of K elements (such that N ≤ K) from these N elements is:
[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]
Then if we have 8 different types of carpet, and we want to see how many different samples of 3 types we can choose, we just need to replace N by 8, and K by 3 in the above equation:
[tex]C(8, 3) = \frac{8!}{(8 - 3)!*3!} = \frac{8!}{5!*3!} = \frac{8*7*6}{3*2} = 56[/tex]
So there are 56 different samples.
Now we can do the same, but this time we want to use 5 types of carpet, then we will have K = 5.
[tex]C(8, 5) = \frac{8!}{(8 - 5)!*5!} = \frac{8!}{3!*5!} = 56[/tex]
Again, we have 56 different samples.
B. Perform the following operations on polynomials.
1. (2x + 3y) - (5x – 2y)
2. (9x²y + 5xy - 2) + (-12x²y – 3xy + 2)
3. (8x + 2y - 3z") + (42* - 5x + 3y)
4.(- 10x*yz? + 5xyz-2) -(10xyz + x - 10 xy)
5. (3x + y) - (2x + z)

If -3x + 5 > 4, which of the following cannot be a value of x? 7.11B-S)
A -3
B -1
C о
D 4
Answer:
D
Step-by-step explanation:
Solving the inequality
- 3x + 5 > 4 ( subtract 5 from both sides )
- 3x > - 1
Divide both sides by - 3, reversing the symbol as a result of dividing by a negative value.
x < [tex]\frac{1}{3}[/tex]
The only value not less than [tex]\frac{1}{3}[/tex] is 4 → D
Pls help I have no idea
Answer:
Step-by-step explanation:
If you connect the chord ends to the center you will see that you form a right triangle where:
[tex]r^2=16^2+\left(\frac{9x-15}{2}\right)^2\ and\ r^2=16^2+\left(\frac{7x+5}{2}\right)^2\\ \\
\text{From these equations we can see}\\ \\ (9x-15)^2=(7x+5)^2\\ \\ 9x-15=7x+5\\ \\ 2x=20\\ \\ x=10[/tex]

What happens when a figure is dilated .
Answer:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A dilation that creates a larger image is called an enlargement. A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure.

The sum of 6 times a number and 8 times another number is 12. The difference of those numbers is 9. What are the two numbers
Answer:
(x,y): (6 , -3) or (-30/7 , 33/7)
Step-by-step explanation:
6x + 8y = 12
x = y + 9 or y = x+ 9
if x = y+9
6*(y+9) + 8y = 12
14y = -42
y = -3 and x = 6
if y = x+9
6x + 8*(x+9) = 12
14x = -60
x = -30/7 and y = 33/7
