Who can help me on my math I’m failing can y’all please help me on some questions.
Gemiola [76]

Answer:

7 quarters, 8 nickels

Step-by-step explanation:

So the system of equations you have is:

x + y = 15

0.25x + 0.05y = 2.15

Here's how to solve:

first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:

25x + 5y = 215

Then, you can divide both sides by 5 to simplify it more:

5x + y = 43

Now, you have the system of equations:

5x + y = 43

x + y = 15

Now subtract the two equations:

4x = 28

divide both sides by 4

x = 7

plug x = 7 into the equation x + y = 15 to solve for y:

7 + y = 15

subtract 7 from both sides

y = 8

So you know that there are 7 quarters and 8 nickels.

Does (1, 1) make the inequality 7x + 7y &gt; 14 true?<br> yes<br> no
gayaneshka [121]

Answer:

no

Step-by-step explanation:

use substitution

if (x,y)=(1,1)

7(1)+7(1)>14 ?

7+7>14 ?

14>14 X

the answer is no because 14 is not greater than 14, 14 is equal to 14 so this inequality is not true with (1,1)
