56/72 can be simplified to 14/18, then to 7/9 *dividing by 4, then by 2*
28/32 can be simplified to 7/8 *dividing by 4*
70/90 can be simplified to 7/9 *dividing by 10*
7/9 and 7/9 are equivalent, so 56/72 and 70/90 are equivalent.
1) So writing in terms of x, we have: y=30,000-2000x or f(x) = -2000x +30,000
Hence, the y intercept is the point 30,000 ( 0, 30000) and the slope is -2000 for it is a decreasing function.
2) Identifying the variables we have, setting a table
Answer:
The answer is 13.
Step-by-step explanation:
Nearest whole number means <em>r</em><em>o</em><em>u</em><em>n</em><em>d</em><em> </em><em>o</em><em>f</em><em>f</em><em> </em><em>a</em><em>t</em><em> </em><em>"</em><em>Ones</em><em>"</em><em> </em>place<em> </em>:
e.g
1.59
≈ 2
3.1
≈ 3
For this case we have:
By definition, the Addition Property of Equality establishes that an equality is not altered as long as the same number is added on both sides of it. That is to say:
can be rewritten as:
If we have:
We can add 6 to both sides of the equation, obtaining the following:
Proving that the statement is true.
Answer:
Addition Property of Equality
The number of hours that Jasmine can work so she can afford the new headphones x = 6 weeks.
let x represent the number of weeks it will take to save enough money.
If she saves $11 each week, then in x weeks she will save 11x dollars.
Add this to the 107 she has already saved, and at the end of 11 weeks she will have
11x + 107 dollars.
We want the amount saved to be equal to the price of the bike, so our equation is
11x + 107 = 173
In a word problem, writing the equation is usually the hardest part. Now we solve the equation.
Subtract 107 from both sides to get
11x = 66
Divide both sides by 11 to get
x = 6 weeks.
