Could someone please explain "Variables on Both Sides of a Complex Equation"?

vodka [1.7K]

Answer:

Step-by-step explanation:

Let's start with an equation like 2x+4=10. We have to isolate x to get an answer. We go for the number without the variable first.

2x+4=10

Subtract 4 from both sides.

2x+4-4=10-4

2x=6

Divide by 2.

2/2=6/2

x=3

There you go!

A scientist cools some water at a constant rate. the graph and table show how the temperature of the water changes with time.

irina1246 [14]

Answer:

Step-by-step explanation:

The easiest way to determine this is to realize that time is the independent variable (n) and temperature is the dependent variable (a).

From the table, we can plug in the two points (n) into n of each equation and see if that equals the temperature values (a).

A little thinking would get us to plug the numbers in C first.

$a(n)=46-(n-1)*4\\46-(5-1)*4=30$

Works!!

Now, second number:

$a(n)=46-(n-1)*4\\46-(6-1)*4=26$

Works!!

Hence, C is the correct answer.

How many 3 digit numbers can be formed from the digits 2, 3, 5, 6, 7 and 9 which are divisible by 5 and none of the digits is re

Number of 3 digit numbers can be formed from the digits 2, 3, 5, 6, 7 and 9 which are divisible by 5 and none of the digits is repeated is 20

A permutation is an act of arranging the objects or numbers in order. Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.

Given,

The digits = 2,3,5,6,7 and 9

The number should be divisible by 5 and the digits cannot be repeated

When the unit digit of the number is either 5 or 0, then the number will be divisible by 5.

Number of possible ways to fill the unit place = 1

Number of possible ways to fill the tens place = 5

Number of possible ways to fill the hundredth place = 4

Number of three digit number can be formed =4×5×1=20

Hence, the number of 3 digit numbers can be formed from the digits 2, 3, 5, 6, 7 and 9 which are divisible by 5 and none of the digits is repeated is 20

When the smaller of two consecutive integers is added to to two times the larger, the result is 29

KengaRu [80]

Let the numbers be X and X+1. X+2(X+1)=29 X+2X+2=29 3X=29-2 X=27/3 X=9. Thus, the Numbers are therefore 9 and 9+1=10 i.e 9 & 10. Thus, when 9 is added to (2*10=20), the result is 29.
