Answer:a) L.C.M OF 2,3,5 is 30
THEREFORE=60/30+15/30÷10/30-6/30
=60/30+15/30×30/10-6/30(DMAS)
=60/30+3/2-6/30
=60+45/30 -6/30(ADDITION FIRST THEN SUBTRACTION.
=105/30-6/30
=105-6/30
=99/30
=33/10
b)(3+1/2)÷(2-1/2)=L.C.M IS 2,=(6+1/2)÷(4-1/2)=7/2÷3/2=7/3
To solve this question, you need to do 421 divided by 9.
421 divided by 9 will get you a long number, which is 46.7777778.
Round your number up by the hundredths place. You will get 46.78.
The average speed in miles per hour would be 46.78 MPH.
Answer: 14,658,134,400
<u>Step-by-step explanation:</u>
There are 52 numbers to start with. After choosing the first number, there are 51 numbers remaining, etc.
1st and 2nd and 3rd and 4th and 5th and 6th
52 x 51 x 50 x 49 x 48 x 47 = 14,658,134,400
You can also find the answer using the following formula:

The value of x in the algebraic equation is: -5/2.
<h3>How do you Find the Value of a Variable in an Algebraic Equation?</h3>
Given an algebraic equation, to find the unknown value of x, solve by isolating x in the equation.
Given:
4x + 26 = 16
Subtract 26 from both sides
4x = 16 - 26
4x = -10
Divide both sides by 4
x = -10/4
x = -5/2
Therefore, the value of x in the algebraic equation is: -5/2.

If e-the initial hight of the tree, and the function imply some brackets like
f(x)=30/(1+29e-0.5x) then
for every

the rate of growth is negative, the maximum growth per unit of time would be 30ft
If

then

so the tree couldn't be 2ft tall initially
if the brackets are something like
f(x)=30:(1+29e)-0.5x then the results may differ
