You need to understand PEMDAS, not just memorize it, to use it correctly.

P - first, do parentheses

E - next, do exponents

The first two are done one at a time in that order. Now we get to MDAS. Here we have two groups of operations. The first group is MD, multiplications and divisions.

MD - then do multiplications and divisions, from left to right, in the order they appear

The second group is additions and subtractions.

AS - finally, do additions and subtractions, from left to right, in the order they appear.

Now let's look at your problem and follow PEMDAS correctly.

19 + 14 \div 10 \cdot 4 - 24 =

P - there are no parentheses.

E - there are no exponents.

MD - now we do multiplications and divisions, from left to right, in the order they appear. Do one operation at a time per line, so you don't forget to do any operation.

We start with the division 14/10:

= 19 + 1.4 \cdot 4 - 24

Now we have a multiplication, so we do the multiplication 1.4 * 4.

= 19 + 5.6 - 24

All multiplications and divisions are done. Now we move on to the step AS. We do additions and subtractions from left to right. We start with the addition 19 + 5.6.

= 24.6 - 24

Finally, we have a single operation left to do. We do the subtraction 24.6 - 24.

= 0.6

Answer: C 0.6

Count the left handed and right handed spirals on the cacti in the photograph you should get two consecutive terms of the Fibona
lana [24]
You can count the spirals because they are coloured.

The left handed spirals are in red and you can count 13.

The rifht hanged spirals are in yellow and you can count 21.

Fibonacci sequence is: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... From 2 the next number is the sum of the two previous numbers:

2 = 1 + 1

3 = 2 + 1

5 = 3 + 2

8 = 5 + 3

13 = 8 + 5

21 = 13 + 8.

Fibonacci numbers are found in many structures in nature.

We have just found that these cacti enclose Fibonacci numbers 13 and 21.

Answer: 13 and 21

What value can be written on the blank line to make the expressions equivalent
Gala2k [10]
<span>The expression is missing from the question, but here is the given expression which I got from a similar question.

48 + 54 = ___ ´ (8 + 9)

Theleft-hand side of the equation is:
                                                             48 + 54 = 102
Now the right-hand side of the equation:
                                                                    A </span>× (8+9) = Right-hand side
                                                                    A × (8+9) = 102
Solving for the unknown variable A,
                                                                    A × 17 = 102
Dividing by 17 on both sides,
                                                A × 17 ÷ 17 = 102 ÷ 17
                                                         A × 1 = 6
                                                              A = 6

Hence,
           48 + 54 = 6 x (8 + 9)
