30 - 8 =22 15x1.50=21.00 SO HE CAN BUY 15 TICKETS FOR RIDES
(-y+5x3)+(7.2y-9)=6.2y+n
(-y+15)+(7.2y-9)=6.2y+n
since you're adding the two parentheses, you don't need to have them there
-y+15+7.2y-9=6.2y+n
7.2y-y +15-9 =6.2y+n
6.2y + 6 =6.2y+n
6.2y - 6.2y -n = -6
-n=-6
n=6
Answer:
The number of women teachers attending the lecture is 1.
Step-by-step explanation:
Denote the variables as follows:
<em>M</em> = men

n (W) = 29
n (T) = 4
n (M ∪ T) = 24
Compute the number of men teachers as follows:
