Keith bought 8 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 30 cards left. How many cards did Keith start with?
please help!!!
Answers
Answer:
52 cards
Step-by-step explanation:
call the amount he started with " x "
then he bought 8 cards
so the new equation is
x+8
then he lost half of his cards
so now the equation is
(x + 8 )/2
that amount to 30 cards as per what is given in the problem
so now the equation is
( x + 8 )/2 = 30
solve using inverse operations and simplifying
( x + 8 )/2 = 30
*2 *2
x + 8 = 60
-8 -8
x = 52

Rewrite the following equation in slope-intercept form.
17x + 18y = -6
Answers
Answer:
y= -17/18x-1/3
Step-by-step explanation:
The slope-intercept form of the equation is y = (-17/18)x -1/3.
What is linear equation?Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.
Given:
A linear equation 17x + 18y = -6.
To find the slope-intercept form:
Simplifying,
17x + 18y = -6
18y = -6 -17x
y = -17/18x -1/3
Therefore, y = (-17/18)x -1/3 is the slope-intercept form.

The length of a new rectangular playing field is 2 yards longer then double the width. If the perimeter of the rectangular playing field is 322 yards, what are its dimensions?
Answers
Answer:
Step-by-step explanation:
First, we want to take the information we have and turn it into an equation, where x is our unknown dimension. For this problem, it would be better if x was equal to the width.
Let's write out the equation:
X is the width, 2x + 2 is the length, and we are multiplying both by two since there are two sides of the field. It will all equal to 322, because that is the perimeter.
2*x + 2(2x +2) = 322
Now, let's solve:
2*x + 2(2x + 2) = 322
2x + 4x + 4 = 322
6x + 4 = 322
6x = 318
x = 318 ÷ 6
x = 53
The width is 53 yards. To find the length, we multiply 53 by two and add two.
53 * 2 + 2 = 106 + 2 = 108 yards, as the length

Why can't a whole number be irrational? Please dumb it down for me
Answers
Answer and Step-by-step explanation:
A whole number isn't irrational because it is a whole number. Confused? Most likely.
A whole number is any of the numbers {0, 1, 2, 3, ...} etc. There is no fractional or decimal part. And no negatives. Example: 5, 49 and 980 are all whole numbers.
An Irrational Number is a real number that cannot be written as a simple fraction. Irrational means not Rational. The irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.
These are both real numbers because they don't go through the 4th wall (of science/math)
Imaginary numbers would use i.

To work out this you need to do the change in y/ the change in x.
So we take 2 points you are given in the table- e.g (1,5) and (2,1)
So the change in y is from 5 to 1 so it is -4 and the change in x is from 1 to 2 so is 1.
Then you have -4/1 which is just -4.

Answers
Answer:
Area = 200 + 50 + x
Step-by-step explanation:
Given
Length = 20
Width = 30
Side Walk = x
Required
Determine the area.
To do this we need to get the new worth and length by adding the length of the sidewalk.
This gives:
Length = 20 + x.
Width = 30 + x
So, area becomes.
Area = (20 + x)(30 + x)
Area = 600 + 20x + 30x + x²
Area = 200 + 50 + x²
