How many solutions does the following equation have 3(X + 9) = 2x + 54
kotykmax [81]

Answer:

One solution.

Step-by-step explanation:

3(x + 9) = 2x + 54

3x + 27 = 2x + 54

3x + 27 - 2x = 2x + 54 - 2x

x + 27 = 54

x + 27 - 27 = 54 - 27

x = 27

One number exceeds another by 26. the sum of the numbers is 58. what are the numbers
Gnom [1K]
First number = X

second number = x +26  ( exceeds means higher so add 26)

x + x+26 = 58

combine like terms:

2x + 26 = 58
 subtract 26 from each side:

2x = 58-26

2x = 32

divide both sides by 2:
x = 32/2
x = 16

first number is 16
second number = 16+26 = 42

hammer [34]

Answer:

Sally has been measuring the tree for 4 months

Step-by-step explanation:

The correct question is as follows;

Sally has been measuring the tree in her yard for a science project. The tree has grown 1/2 of an inch each month and grown a total of 2 inches taller. How many months has Sally been measuring this tree?

.........................................................................................

Solution;

The tree has grown 1/2 of an inch each month and has grown a total of 2 inch taller.

We now need to know the number of months in which the measuring has been taking place.

To know the number of months, we simply need to divide the change in height which is 2 inch by the individual month growth rate which is 1/2 inch

So mathematically, that would be 2/1/2 = 2 * 2 = 4 months

Estimate it as a whole number
denis-greek [22]

Answer:

2

Step-by-step explanation:

First, you do the subtraction 120-21.4 which is 98.7. So since you know its x^7, the number isn't going to be big. By guessing and checking, we start with 2. 2^7 is 128. We know that 1^7 would just be 1, so the closest whole number would be two.
