Answer:
Step-by-step explanation:
If Quan had 15 and Kaden had 3 times as much, then Kaden had 15(3) = 45. If he spent 10 then he had 35 left. The amount of money Quan had after his mom gave him some was 4/5 the amount of Kaden's 35 (let x = the amount of money Quan has after his mom gives him some):
35 divides by the 5 in the denominator 7 times, and 7 times 4 is 28. That's how you get your 28 in part a.
For part b., he started with 15 and ended with 28, so his mom gave him 28-15=13. That's how you get the 13.
Answer:
$18.20/0.65=28 minutes
Step-by-step explanation:
$18.20 was the cost of the rental divide it by the cost per minute and that will give you the total number of minutes used which is 28.
Answer:
A.
Step-by-step explanation:
Use the distributive property.
(2<em>x</em> − 2<em>y</em>)(2<em>y</em> + 8)
= 2<em>x</em>(2<em>y</em> + 8) − 2<em>y</em>(2<em>y</em> + 8)
= 4<em>xy</em> + 16<em>x</em> − 4<em>y</em>^2 − 16<em>y</em>
Answer is 1/36...
probability of rolling a 3 is 1/6 so if you do it twice it will be 1/6×1/6=1/36
Answer:
Option C
Step-by-step explanation:
Given the following question:
<u>Using the process of elimination, we can find the answer:</u>
It's not option A, because in order for a table to be a linear function the change of x, and the change of y have to be constant. In this case our change in y goes through -2, to -1. Which means option A is not a linear function.
It's not option A because again in order for a table to be a linear function the change of x and the change of y have to be constant. In this case our change of x is constant but our change in y isn't.
It's not option D because in order to have a linear function, you have to be able to rewrite the function into slope intercept (y = mx + b) in this case we only have one real number which is 12, while having our x, and y variable. Which means option D isn't a function.
Which leaves option C or "4x + 3y = 12" which is your answer, because it can be rewritten in slope intercept form.
Hope this helps.
