5z-79=61

Solve for x:

A straight line is 180 so...

180-61=119

Solve for z:

5z=61+79

5z=140

Z=140/5

Z=28

What is the sum of all of the perfect squares between
Nonamiya [84]

Answer:

(-138) is the answer.

Step-by-step explanation:

Perfect square numbers between 15 and 25 inclusive are 16 and 25.

Sum of perfect square numbers 16 and 25 = 16 + 25 = 41

Sum of the remaining numbers between 15 and 25 inclusive means sum of the numbers from 17 to 24 plus 15.

Since sum of an arithmetic progression is defined by the expression

S_{n}=\frac{n}{2}[2a+(n-1)d]

Where n = number of terms

a = first term of the sequence

d = common difference

S_{8}=\frac{8}{2} [2\times 17+(8-1)\times 1]

   = 4(34 + 7)

   = 164

Sum of 15 + S_{8} = 15 + 164 = 179

Now the difference between 41 and sum of perfect squares between 15 and 25 inclusive = 41-179

= -138

Therefore, answer is (-138).

(3/5) cubed Please explain to me how you would do this
krek1111 [17]
<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷  It would be done in the same way it would if it was an integer ;

think of it as two separate parts

(3/5)^3 = 3/5 * 3/5 * 3/5

Calculate the top half, then the bottom half and put them together

3 * 3 * 3 = 27

5 * 5 * 5 = 125

Thus, your answer will be 27/125

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
