Answer:

Ivy is 6 years old and Rose is 12 years old.

Step-by-step explanation:

To solve this problem, two variables are necessary since we have two unknown variables: Ivy's age and Rose's age.

Ivy's age will be x

and Rose's age will be y

"Ivy is half as old as her sister":

x=\frac{y}{2}

this will be our <u>fist equation.</u>

"In six years, Ivy will be two-thirds as old as Rose"

in six years Ivy will have x+6 years, and Rose will have y +6 years, so for this sentence we have the equation:

x+6=\frac{2}{3}(y+6)

this will be our <u>second equation.</u>

Substituting the value of x from the first equation into the second, and solving for y(Rose):

\frac{y}{2}+6=\frac{2}{3} (y+6)\\\frac{y+12}{2} =\frac{2}{3} (y+6)\\y+12=\frac{4}{3} (y+6)\\3(y+12)=4(y+6)\\3y+36=4y+24\\36-24=4y-3y\\12=y

Rose is 12 years old.

and Ivy (using the fist equation):

x=\frac{12}{2}=6

Ivy is 6 years old.

20 points<br> What is the value of p in the linear equation ?<br><br> −4<br> −2<br> 2<br> 4
Nikolay [14]

Answer:

p=-2

Step-by-step explanation:

24p+12-18p=10+2p-6  

Subtract what is to the right of the equal sign from both sides of the equation.

24p+12-18p-(10+2p-6)=0

Then pull out the like terms(factors)

Which is: 4p+8

=4(p+2)

Put that to 0 and 4=0 which is not a solution because it's a non-zero constant.

So now put  p+2=0, subtract by 2 on both sides and the 2 cancels out and on the right side you have -2

p=-2

Mother bought a basket for 10% discount.how much is the tag price if the price was Php250.00?​
Svetllana [295]

Answer:

The tag price would be 275 dollars.

Step-by-step explanation:

10% of 250.00 is 25. But the tag price is without the discount and the 250.00 is with the discount. So, if you add 25 to 250 you get 275.
