Evaluate: -1 2/5 ÷ 14/15

Mathematics

Sergio [31]3 years ago
3 0

Answer:

Step-by-step explanation: Turn the mixed number into an improper fraction. -1 2/5 becomes -7/5.  To divide fractions, you keep the first fraction, change the division sign to mulitplication and flip the second fraction.  Then just multiply across the top and across the bottom. You will get 105/70.  Reduce by dividing both numerator and denomination by 35   Result will be 3/2.

This is a problem in pattern matching, and in substituting a variable for a pattern.

  (x^2 +3)^2 +7(x^2 +3) = -10 . . . . . factor the last two terms

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he
vladimir2022 [97]
We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.

This sets up a problem of:

6x + 7 = 4x + 13

7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.

x = 3

Knowing this, we plug in x for one of the equations

6(3) + 7
18 + 7
25

Liam has 25 chairs.
