Just saying this could be a linear equation of
7x+25y=231
And you can graph that if you solve for both x and y to get each of their coordinates
But
I got
7(8)+25(7)=231
Just by testing and plugging in values
So 8 vans 7buses
Pi/3 is in the first quadrant, and all trigonometric functions are positive in the first quadrant,
Therefore, cos pi/3 is positive.
Step-by-step explanation:
1/2 (c +1)>5 = c≥9
27-2b<-6=b≥332
Answer:
19x
Step-by-step explanation:
The cost of the racing cars was ...
2(5x) = 10x
The cost of the model motorcycles was ...
3(3x) = 9x
Peggy paid in total ...
10x + 9x = 19x
