Answer:
Step-by-step explanation:
Let x and y represent the numbers of small and large cars washed, respectively.
We know that:
$4.50x + $8y = $420
But we don't know the relationship between x and y. We need more information (e.g., they washed twice as many small cars and large). Otherwise we have one equation and two unknowns. Since there are two unknowns, we can't determine a "slope" of the line. With all the water and soap, the most we could possibly say it will be a slippery slope.
Answer:
Graph A
Step-by-step explanation:
As we know, in 3 minutes he washes 18 dishes. Without even doing any math, you can see that this is the only graph that represents that. The others show that he washes two dishes in 12 minutes, which doesn’t make sense.
Answer:
And if we solve for y we got:
And replacing we got:
And we got:
And for x we got:
So then the length would be 76 and the width we got 12.5
Step-by-step explanation:
For this case we have a rectangle. The perimeter is given by:
Where x represent the length and y the the width. We can set the following conditions:
And if we replace the conditions we got:
And if we solve for y we got:
And replacing we got:
And we got:
And for x we got:
So then the length would be 76 and the width we got 12.5
Ans: 5*-3=-15
Step-by-step explanation:
The product of a positive and negative integer is negative.So, the product of 5 and -3 is -15
It is 350 euros, look on the first day you have to have greater than 315 euros and the only number that is greater is 350
