So what we have to do to solve this problem is to write down those values in 2 equations (one that represents what you sold and the other what your friend sold) compare them and find how much each ticket is worth.
First equation : 11x + 8y = 158
Where x = how much each adult ticket is
and y = how much each student ticket is
The second equation is : 5x + 17y = 152
Using the method of substitution , we can compare each equation side by side:
11x + 8y = 158
5x + 17y = 152
Now we need to set one of the variables of both equations so they are equal:
11(5)x + 8(5) = 158(5)
5(11)x + 17(11)x = 152(11)
55x + 40y = 790
55x + 187y = 1672
Then we subtract the second equation by the first one
55x-55x + 187y - 40y = 1672 - 790
147y = 882
y = 6
The we apply y to one of the equations to discover x :
11x + 8y = 158
11x + 8(6) = 158
11x + 48 = 158
11x = 110
x = 10
So the awnser is :
Each adult ticket (x) is $10
And each student ticket (y) is $8
I hope you understood my explanation,
Answer:
c
Step-by-step explanation:
Answer:
Use the formula y-y1=m(x-x1) <---memorize this. The m here is the slope.
Step-by-step explanation:
The equation is in y=mx+b form
Remember mx=slope and b=y-intercept
The question wants you to find the equation that is Parallel to y=-3x-2 and passes through (-3,-3)=(x1,y1)
Parallel=same slope -3x
So now all that's left is to plug into the equation.
y-(-3)=-3(x-(-3))
y+3=-3(x+3) ----> positive - a negative = positive so x-(-x)=x+x
y+3=-3x-9 ----> distribute like terms(subtract 3 from 3 and 3 from -9)
y=-3x-12 - This is your answer, you can check by graphing it.
Could i get Brainlest? thx :)
70 flowers were planted in all.
Step-by-step explanation:
Let,
Tulips = t
Daises = d
Lilies = l
Total tulips planted = 42
She planted 2 times as many tulips as daises.
t=2d
Putting t=42
Dividing both sides by 2
And 3 times as many daisies as lilies.
d=3l
Putting d=21
Dividing both sides by 3
Total flowers planted = Tulips + Daisies + Lilies
Total flowers planted = 42 + 21 + 7 = 70
70 flowers were planted in all.
