Answer:
401.92 in²
Step-by-step explanation:
S.A. = 2πr²+2πrh
S.A. = 2π4²+2π4·12
S.A. = 100.48 + 301.44
S.A. = 401.92 in²
X=8-y
2(8-y)=10
16-2y=10
-2y=10-16
-2y=-6
y=3
x+3=8
x=8-3
x=5
(5,3) is the answer :)
Laila=l
Tom=t
Dan=d
l=t+14
l=d-5
l+t+d=51
In terms of l:
d=l+5
t=l-14
So:
l+l+5+l-14=51
3l+5-14=51
3l-9=51
3l=60
l=20
d=25
t=6
Hope this helps :)
Answer: option 4 x < 175
x/5 < 35
multiply both sides by 5
x < 175
(i can’t do the correct symbol but you get the idea)
