Ok so in solving systems of linear equations, we first find the value of a variable. By looking at the equations, solving for x by using the second equation seems the easiest.
x - y = -5
x = -5 + y
x = y - 5
Then we plug in the equation of x into the first equation and solve for y.
x - 2y = 19
y - 5 - 2y = 19
-3y - 5 = 19
-3y = 24
-y = 8
y = -8
Now we plug in y = -8 in the solved equation for x
x = y - 5
x = -8 - 5
x = - 13
Therefore, x = -13 and y = -8
Hope this helps!
Answer:
They bought 23 tickets for children and 52 for adults.
Step-by-step explanation:
So first you must find what i represents so here it is
A= Adult
C= Children
They both sold the tickets which is going to be
A + C = 75
Now here it shows
12= each adult ticket
8= each children ticket
find the equation like this 12 A + 8C = 808
Now to find the C
You can find by resolving it like this
C= 75 - A
Solve the A and C
4A = 208
A = 52
12 (52) + 8C = 808
624 + 8C = 808
Children = 23
Adult= 52
Answer:
6 units
Step-by-step explanation:
Using readings taken from the coordinate upon which the triangle is drawn :
The area of triangle is given as :
Area of triangle = 0.5 * base * height
The base of the triangle = 4 units
The height of the triangle = 3 units
The Area of the triangle is thus :
0.5 * 4 * 3
0.5 * 12
= 6 units

duh obviously the answer is idk, and let me tell you why
Step-by-step explanation:
because when you add 2+4 and then it gives you 78 now you can square root that 78 and it will give you 8 and after that you get 8 of your fingers and play with yourself a little bit but not too much, therefore the answer is idk.
hope i was helpful
