Answer:
(2,16)
Step-by-step explanation:
y=8x-----------(i)
y= 10x-4---------(ii)
Substituting the value of y=8x in equation (ii)
8x=10x-4
8x-10x=-4
-2x= -4
x=2
Now, substituting the value of x= 2 in equation (i)
y=8x=8(2)=16
Solution of the system is (2,16)
Answer: 69/15=4 and remainder 9
Step-by-step explanation: Since 15 x 4 = 60, 15 can't go into 9 so 9 in the leftover
Answer:
x=3 and y=2
Step-by-step explanation:
1.) 4x+3(5x-13)=18
expand into 4x+15x-39=18
18+39= 57
15x+4x= 19x
57/19= 3 so x=3
substitute 3 into y= 5x - 13
and you get 2 so y=2
Answer:
2.5
Step-by-step explanation:
56(t+1/2)=70 t
56T + 28= 70T
28=70T-56T
28=14
2=T
s=T+ 1/2
S=2+ 1/2
S=2.5 hours
Answer:
Hi there!
The correct answer is: 2.185 in
Step-by-step explanation:
The formula for the volume of cylinder is: V= Base * Height
where base is π * radius²
So given that information, we can first divide 10 on sides to get πr²= 15
then divide pi on both sides to get 4.7746 then square root both sides to get
r=2.185
