Answer:
15
Step-by-step explanation:
if you put x=-15
f(x) = 5*-5 +40
=-25+40
=15
So how many times does 92 go into 181? Well only once. So the mixed part of the fraction would be 1.
181/92 = 1 89/92
Answer:
327 children and 318 adults
Step-by-step explanation:
The x be the amount of children and y be the amount of adults that were at the swimming pool. We can use this to set up a system of equations:
x+y=645
1.75x+2.50y=1367.25
Move y to the other side in the first equation to isolate x and solve the system using substitution:
x=645-y
1.75(645-y)+2.50y=1367.25
Distribute
1128.75-1.75y+2.50y=1367.25
1128.75+0.75y=1367.25
Subtract 1128.75 from both sides
0.75y=238.5
Divide both sides by 0.75
y=318
x=645-y
x=645-318
x=327
327 children and 318 adults swam at the pool that day
An asexual structure where spores develop is Sporangium
The answer is 45 when you substitute all the variables in
