Answer: (I think it is x=4)
x=4, x=2, or x=10
Step-by-step explanation:
Simplifying
3x + 2(5x) = 26
Remove parenthesis around (5x)
3x + 2 * 5x = 26
Multiply 2 * 5
3x + 10x = 26
Combine like terms: 3x + 10x = 13x
13x = 26
Solving
13x = 26
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '13'.
x = 2
Simplifying
x = 2

Pulling out like terms
3.1 Pull out like factors :
20 - 2x = -2 • (x - 10)
Equation at the end of step

:
-2 • (x - 10) = 0

Equations which are never true
4.1 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x-10 = 0
Add 10 to both sides of the equation :
x = 10
One solution was found :
x = 10
--------------------------------------------------------------------------------
(3x-3*2)+5x=26
(3x-6)+5x=26
3x-6+5x=26
3x+5x-6=26
8x-6=26
(8x-6)+6=26+6
8x-6+6=32
8x=32
8x/8=32/8
x=2^5/2^3
x=2^5-3
x=2^2
x=4
Answer:
B
Step-by-step explanation:
The tangent of an angle is the ratio of the opposite side to the adjacent.
With respect to Angle A, the opposite side is 12.
And the adjacent side is 5.
Therefore:
![\displaystyle\tan(A)=\frac{\text{opp}}{\text{adj}}=\frac{12}{5}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Ctan%28A%29%3D%5Cfrac%7B%5Ctext%7Bopp%7D%7D%7B%5Ctext%7Badj%7D%7D%3D%5Cfrac%7B12%7D%7B5%7D)
The answer is B.
The "mean" is the same thing as the "average".
To get the average, you add up all the numbers on the list,
then divide the big sum by the number of items on the list.
If there are 100 numbers on the list, then in order to find their average,
you would add up all 100 numbers, then divide the big sum by 100.
If you wound up with an average of 51.18, then you must have had
5,118 just before you divided it by 100. So the big sum is 5,118.
Answer:
6
Step-by-step explanation:
**6** (total) / **3** (a third) **=2** (how many eggs hatched)
Answer:
He would need 6 red roses and 9 pink daisies to make 3 bouquets.
Step-by-step explanation:
10 red roses and 15 pink daisies are needed for 5 bouquets. This means he would need 10/5 = 2 red roses and 15/5 = 3 pink daisies for 1 bouquet. This also means that he would need 2(3) = 6 red roses and 3(3) = 9 pink daisies for 3 bouquets.
