Answer:

length=25 width=17

Step-by-step explanation:

l+w=42

start by guessing a pair of numbers that equals 42 i chose 22+20

since these two numbers are 2 digits apart,

5-2=3

now we have to add 3 to 22 and subtract 3 from 20

now it is 25+17 which still equals 42

Hey there!

ANSWER: $\frac{23}{20}$

EXPLANATION:

To find the answer to your question, you will need to add.

$\frac{3}{4}+\frac{2}{5}$

First, multiply the denominator.

$5*4=20$

So the denominator will be 20.

Now move on to the numerator. Multiply 5 by 3.

$5*3=15$

Now multiply 4 bu 2.

$4*2=8$

If you want to get the numerator, add what you got after multiply.

$15+8=23$

The numerator is 23. So now let's complete the fraction.

$\frac{23}{20}$

This is your answer!

Hope this helps!

The first term of a sequence is a multiple of 3 The second term of this sequence is 6 less than the first term. The third term i

Mekhanik [1.2K]

Answer:

First term $= 15$

Second term $= 9$

Third term $= 3$

Step-by-step explanation:

Given,

First term $= 3x$

Second term $= 3x - 6$

Third term $= \frac{1}{5} (3x) = \frac{3x}{5}$

Also,

$3x - \frac{3x}{5} = 12$

$\frac{15x}{5} - \frac{3x}{5} = 12$

$\frac{15x - 3x}{5} = 12$

$15x - 3x = 12 \times 5$

$12x = 60$

$x = \frac{60}{12}$

$x = 5$

With the value of $x$ , we conclude that the first three terms are as follows:

First term $= 3x = 3×5 = 15$

Second term $= 3x - 6 = 15 - 6 = 9$

Third term $= \frac{3x}{5} =\frac{15}{5}= 3$
