Answer:
36000
Step-by-step explanation:
The unknowns : number of boys (b) and number of girls (g)
b + g = 23
g = b + 7
b + b + 7 = 23
2b + 7 = 23
2b = 23 - 7
2b = 16
b = 16/2
b = 8 <=== there are 8 boys
g = b + 7
g = 8 + 7
g = 15 <=== there are 15 girls
Y= x^2 -10 and y= 3x-18 have a solution of (-4,6)
