Answer:

x = -24

y = 66

Step-by-step explanation:

12x+9y = 102

12x+16y = 432

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

y = 66

4x + (66*3) = 102

198-102 = -96

-96 / 4 = -24

Answer:

solution is (6,10)

Step-by-step explanation:

4x+3y=54

3x+9y=108

WE use elimination method to solve for x and y

Multiply the first equation by -3

-12x-9y=-162

3x+9y=108

Now add both the equations, we will get

-9x=-54

Divide by   -9 on both sides

x=6

Now we plug in the x value in first equaiton and find out y

4x+3y=54

4(6)+3y=54

24+3y=54, subtract 24 on both sides

3y=30

Divide both sides by 3

y=10

So solution is (6,10)

75/4=25 pages per hour, so, now we have to divide 250 by 25.

250/25=10

So, it would take Joan 10 hours to read 250 pages. :)

What is the slope hurry!!!!! please !!!!!!
Nina [5.8K]

Answer:

It’s definitely 1/4

Step-by-step explanation:

the answer shoudl be positive since its a positive line

And t can’t be 4 becuase then the line would be slanted upward as becuase 4 up 1 right and this looks more like of a 1 up, 4 right. Try it yourself, try slope fo 4 from the origin since its a gaurteed point in this situation and try 4 and 1/4. 1/4 is way more reasoabnable,

Someone help me pleaseeeee​
Dafna11 [192]

In an isosceles triangle, there are two sides that are congruent.

In this case, AB and BC are congruent.

Knowing this, we know that AB = BC

Since we know the values of AB and BC, we can put them into the equation:

3x - 4 = 5x - 10

Subtract 3x from both sides:

-4 = 2x - 10

Add 10 to both sides to isolate 'x':

6 = 2x

Divide both sides by 2:

x = 3

Now that we know the value of the variable, we just have to input it into AB's equation:

3x - 4 = 3(3) - 4

3(3) - 4 = 9 - 4

9 - 4 = 5

<u>AB = 5</u>

Good luck!
