Fred by the video game deaths for $4 there was a discount of 20% what is the sale price

Answers

If you would like to know what is the sale price, you can calculate this using the following steps:

20% of $4 = 20% * 4 = 20/100 * 4 = $0.8

$4 - $0.8 = $3.2

The sale price would be $3.2.
if the game cost $4, and the discount is 20%, then the sales price is $0.80 because 4 × 0.2 = 0.8

To round a number, you first have to determine what you are rounding to. in this case, it's the nearest dollar. Then, you determine whether to "round up," to the next higher number, or "round down," which is to stay at the number it's currently at, without the numbers following what you're rounding to. If the number after the place you're rounding to is equal to or higher than 5, you'll round up. If it's lower, you'll round down.
So, for your questions, the answers would look like this:
$8.98 rounds to $9.00, because 9 is bigger than 5.
$6.49 would round down to $6.00, because 4 is less than 5.
$2.51 rounds up to $3.00, because 5 is equal to 5.
$9.78 would round up to $10.00, because 7 is higher than 5.
$39.89 will round up to $40.00, because 8 is bigger than 5.
9, 6, 3, 10, 40 because anything .50 and up is rounded up. Anything .49 and below is rounded down.

Fred and ethyl had 132 flowers altogether at first. After Fred sold 1/4 of his flowers and Ethyl sold 48 of her flowers, they had the same number of flowers left. How many did they each have at first?

Answers

F + E = 132
3/4 F = E - 48           ( after Fred sold 1/4 of his flowers there is 3/4 flowers left )
--------------------
E = 132 - F
3/4 F = 132 - F - 48
3/4 F + F = 84
7/4 F = 84
F = 84 : 7/4 = 84 * 4/7 = 48
E = 132 - 48 = 84
We can prove it: 3/4 * 48 = 84 - 48
36 = 36 ( correct )
Answer:
Fred had 48 flowers and Ethel 84 flowers.

Fred had 48 flowers.

Ethyl had 84 flowers.

Simultaneous Linear Equations could be solved by using several methods such as :

  • Elimination Method
  • Substitution Method
  • Graph Method

If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.

Let us tackle the problem!

Let :

Number of Fred's Flowers = f

Number of Ethyl's Flowers = e

Fred and ethyl had 132 flowers altogether at first.

f + e = 132

f = 132 - eEquation 1

After Fred sold 1/4 of his flowers and Ethyl sold 48 of her flowers, they had the same number of flowers left.

f - (1)/(4)f = e - 48

(3)/(4)f = e - 48

(3)/(4)(132 - e) = e - 48Equation 1

(3)/(4)(132) - (3)/(4)e = e - 48

99 + 48 = (3)/(4)e + e

147 = (7)/(4)e

e = 147 / (7)/(4)

e = \boxed{84}

f = 132 - e

f = 132 - 84

f = \boxed {48}

A plants height is 1.6 times its age. Write an equation for the situation, where h is the plants height and y is the plants age

Answers

Answer:  The required equation ish=1.6y

Step-by-step explanation:  Given that a plants height is 1.6 times its age.

We are to write an equation for the situation, where h is the plants height and y is the plants age.

The given situation can be written in equation form as follows :

h=1.6* y\n\n\Rightarrow h=1.6y.

Thus, the required equation ish=1.6y

y x 1.6 = h Because, if the height of the plant is 1.6 times its age all you have to do is multiply y by 1.6 and you'll get the height of the plant
