How many side does the parallelogram has
1/3 = 4/12
(4/12 + 11/12) * 2/3
= 15/12 * 2/3
15/ 12 can also be written as 5/4
5/4 * 2/3 = 10/12
10/12 can be simplified into 5/6
Therefore, the answer is 5/6
Answer:
x =7
Step-by-step explanation:
Remark
- A geometric sequence always has terms that are separated by a common ratio. For example 3 9 27 81 243 ....
- Each term is multiplied by a common number and the term before it. In this case the common term is 3.
- To get the next term after 9, you multiply 9 by 3.
- To get the common ratio divide the second term by the first and then the third term by the second
Equation
(x + 2)/(x - 4) = (3x + 6)/ (x + 2)
Solution
I would begin this problem by taking out the common factor on the top right term. You'll see why in a second.
(x + 2)/(x - 4) = 3(x + 2)/ (x + 2) Notice the two binomials on the right cancel.
- (x + 2)/(x - 4) = 3/1 Cross multiply
- (x + 2)*1 = 3*(x - 4) Remove the brackets on the right.
- x + 2 = 3x - 12 Add 12 on both sides.
- x + 2 + 12 = 3x - 12 + 12 Simplify
- x + 14 = 3x Subtract x from both sides
- 14 = 3x - x
- 2x = 14 Divide by 2
- x = 14/2
- x = 7
Answer:
20
Step-by-step explanation:
set up equation
13/x=65/100
cross multiple: 1300=65x
divide 1300/65=20
Find (-4) on the number line and move 3 to the right. You will end up at (-1).
Find (3) on the number line and move 4 to the left. You will end up at the same value of (-1).
