You have $3.70 in dimes and quarters. You have 5 more

anygoal [31]

Answer:

Step-by-step explanation:

10x + 25y = 370

y = x + 5

10x+25(x+5)=370

10x+25x+125=370

35x=370-125

x=245/35

x=7 which is the number of dimes

x+7= 7+5= 12 which is the number of quarters

So you have 12 quarters. That means you have 7 dimes.

Which system of equations can you use to find the roots of the equation? x3 – 10x = x2 – 6 y = x3 – x2 + 10x + 6 y = 0 y = x3 –

Maslowich

Answer:

answer is:

$y=x^{3}-10 x,y=x^{2}-6$

Step-by-step explanation:

we are asked to find which system of equations can we use to find the roots of the equation:

$x^{3}-10x=x^{2}-6$

since the system of equation in last part is given as:

$y=x^{3}-10 x,y=x^{2}-6$

so, on equating both the equations i.e. on equating both the values of 'y' we get the desired equation as:

$x^{3}-10x=x^{2}-6$ .

The length of the hypotenuse of a 30-60 -90 triangle is 14 units. what is the length of the short leg

kifflom [539]

Recall that the short leg is the side opposite the 30 degrees angle. And the ratio of the short leg to the hypotenuse is 1:2.

Let the length of the short leg be x, then,

$\cfrac{x}{14}=\cfrac{1}{2}\\ \\\Rightarrow2x=14\\ \\\Rightarrow x=\cfrac{14}{2}=7$

Paul,Linda,and Aaron make homemade cards. Paul can make 1 card for every 3 cards Linda makes. Linda can make 3 cards for every 2

dimaraw [331]

Answer:

Linda makes 72 more cards than Paul

during the week

Step-by-step explanation:

Here, we want to know how many cards Linda makes than Paul during the week.

We proceed as follows;

From the question;

If Paul makes 1 card, then Linda has made three

Now let’s get their relationship with Aaron;

If Aaron makes 2 cards , Linda has made three

Now since Aaron made 72 cards, Let’s say Linda has made x cards

Let’s get the value of x now

To get the value of x, we simply cross multiply;

2 - 3

72 - x

2 * x = 3 * 72

x = (3 * 72)/2 = 108 cards

Now recall , for every 3 cards of Linda, Paul made only 1;

So the number of cards Paul will make if Linda makes 108 will be 108/3 = 36

So the number of more cards that Linda makes than Paul during the week will be ; 108 -36 = 72 cards
