1/8 the sum of 23 and 17

Answers

The correct answer is:(1)/(8) (23 + 17) = 5


Explanation:


1/8 the sum of 23 and 17 can mathematically be written as follows:

(1)/(8) (23 + 17)


As the sum of 23 and 17 is written as (23+17), and then multiply it with (1/8).


Now evaluate:

(1)/(8) (23 + 17)

(1)/(8) (40)

= 5


Hence the correct answer is 5

5

Further explanation

The Problem:

  • (1)/(8) the sum of 23 and 17
  • Write an expression to match and then evaluate.

The Process:

Step-1: Determine the sum of 23 and 17

\boxed{ \ 23 + 17 = 40 \ }

Step-2: Calculate (1)/(6) the sum of 16 and 20

(1)/(8) of the sum of 23 and 17 means (1)/(8) multiply the result of adding 23 and 17.

\boxed{ \ = (1)/(8) * 40 \ }

We can cross out 8 and 40 because they can be completely divided, but this time we continue the multiplication process.

\boxed{ \ = (40)/(8) \ or \ 40 / 8 \ }

\boxed{\boxed{ \ 5 \ }}

Thus the result is 5.

Quick Steps:

\boxed{ \ = (1)/(8) * (23 + 17) \ }

\boxed{ \ = (1)/(8) * 40 \ }

\boxed{ \ = (40)/(8) \ or \ 40 / 8 \ }

\boxed{\boxed{ \ 5 \ }}

Solve the equation for the given variable.
Bx+Cy=D

Solve for y

Answers

Bx + Cy = D

Solve for y . .  .

*subtract Bx from both sides

Bx - Bx + Cy = D - Bx

Cy = D - Bx

*now divide both sides by C

Cy/C = (D - Bx)/C

Cy/C = D/C - Bx/C

y = D/C - (B/C)x

y = -(B/C)x + D/C
Bx+Cy=D -- subtract Bx

Cy=D-Bx -- divide by C

y=(D-Bx)/C

The quotient of twice a number t and 12

Answers

2t/12 would be your expression.

Two lines, C and D, are represented by the equations given below:Line C: y = x + 12
Line D: y = 3x + 2

Which of the following shows the solution to the system of equations and explains why?

(4, 14), because one of the lines passes through this point
(4, 14), because the point lies between the two axes
(5, 17), because both lines pass through this point
(5, 17), because the point does not lie on any axis

Answers

If you would like to know what is the solution to the system of equations, you can calculate this using the following steps:

y = x + 12
y = 3x + 2
______________
y = y
x + 12 = 3x + 2
12 - 2 = 3x - x
2x = 10
x = 5

y = x + 12 = 5 + 12 = 17

The correct result would be (x, y) = (5, 17); because both lines pass through this point.

The correct answer is C.

You have 7 balls that are each a different color of the rainbow. In how many distinct ways can these balls be ordered?

Answers

To solve this question, use a factorial. This is a basic concept in permutations. The first ball can be placed into any of the 7 positions. The second can be placed in 6. The third can be placed in 5, and so on until there are no balls left. One easy way to solve this is to use 7!, or seven factorial. 7! = 7*6*5*4*3*2*1. The answer is 5,040 distinct ways.
Hope that answered your question.

Answer:

You have 7 balls that are each a different color of the rainbow. Then, the number of distinct ways in which these balls can be ordered will be given by 7!. 7! = 7*6*5*4*3*2 = 5040 ways. Thus, in 5040 ways, the number of balls can be put in distinct arrangements.

Solve using the Square-Root (x-3)²-49=0

Answers

Answer:

x equals 10 and x equals -4

Step-by-step explanation:

take the square root of (x-3)² and the square root of 49

√(x-3) = x-3

√49 = +7 and -7

substitute the positive and negative 7 in for 'x' and solve

x-3 = 7;   therefore, x = 10

x-3 = -7;   therefore, x = -4
