Add 24+24=48 then 24/3= 8 add 48+8 = 56

To figure out this question, I first divided 24 into 3, which gives me an answer of 8. then I divided 52 into 7 , which also is 8 . because the two numbers are the same, I know the ratios are equivalent.

Julio spent $41 and now has no money left he had BLANK before his purchase. write the integer

timama [110]

Answer:

total = $41

Step-by-step explanation:

If Julio spent $41 and now has no money that means that after spending that money he was left with $0. Having both of these numbers we can make a very simple algebraic equation to find out his total before the purchase.

total - $41 = $0

Now we simply add $41 to both sides which will give us the actual amount of the total.

total - $41 = $0

+$41 +$40

-----------------------------

total = $41

Now we can see that Julio had a grand total of $41 before making his purchases.

What is the constant of proportionality for 6,47.94?

Maurinko [17]

$\boxed{k=7.99}$

<h2>Explanation:</h2>

In this exercise, we have the following point:

$(6,47.94)$

Let's assume that y varies directly as x, so this implies we can writ y as the product of x and some non-zero real constant k. In a mathematical language:

$y=kx$

As you can see, this is the equation of a line whose slope is k and passes through the origin. Therefore, the slope of the line is the constant of proportionality we are looking for:

$Solving \ the \ equation \ for \ k: \\ \\ k\frac{y}{x} \\ \\ Where: \\ \\ x=6 \\ y=47.94 \\ \\ k=\frac{47.94}{6} \\ \\ \therefore \boxed{k=7.99}$
