Wanda has three times more shirts than her brother, Will. The equation a = 3b, where a represents the number of shirts Wanda has
marusya05 [52]

Answer:

8 shirts

Step-by-step explanation:

Given the equation a = 3b, where

a = the number of shirts  Wanda has

b = the number of shirts Wanda's brother (Will) has

Hence if Wanda has 24 shirts then

24 = 3b

Divide both sides by 3

24/3 = b

b = 8 shirts

Will has 8 shirts.

The sum of three numbers is 104. The first number is 10 less than the second. The third number is 4 times the second. What are t
Shalnov [3]

Answer:

The numbers are 9, 19 and 76.

Step-by-step explanation:

Let's take the second number and make it a variable, like x. Now let's find all the other numbers in terms of x.

The first number in terms of x:

x - 10

The second number in terms of x:

4x

If we add them all up, these 3 numbers in terms of x must be equal to 104, so:

x + (x - 10) + (4x) = 104 \\ x + x - 10 + 4x = 104 \\ 6x - 10 = 104 \\ 6x = 114 \\ x = 19

Now that we know the second number, we can find the other numbers since we already figured out their values in terms of x:

19 - 10 = 9

4 \times 19 = 76

The first number is 9, second number 19 and the third number 76.

noname [10]

Answer:  log_39=2 is the logarithmic equation which is equivalent to3^2=9.


Step-by-step explanation:

According to the laws of logarithms

log_b\ x=n ,where b=base ,n,x all are positive

It can be written in exponential form such as

x=b^n

Now in the given question x=9 ,b=3 and n=2 such that it will equals to

log_39=2

Hence the logarithmic equation for 3^2=9 islog_39=2.
