Let me help you with this :)
John = x
Mike = y
x = 4 + 3y (4 more than 3 times)
x + y = 20 (we put the x above into this equation)
4 + 3y + y = 20
4y = 16 (we transfers the 4 on the left side to the right side and subtract it from the 20)
y = 4 (the answer is 4)
we use this for the equation:
x = 4 +3*4
x = 16
John is 16 years old and Mike is 4 years old :)
9+2/3x<1
-9 -9
cross 9-9 out and your 1 becomes a -8
and left with
2/3x<-8
multiply 3 by 2/3 and that cancels 2/3 out. also multiply 3 by your -8
x = -24
Answer: 1 and 3/70
Explanation: Find the least common denominator and then combine like terms. The LCM is 70.
Given the stated equation we know that that quadratic formula has 2 as its degree. This meats it has 2 roots. A linear equation has a degree of 1. A linear equation has 1 root. To know if they intersect, the must have one root in common. To know this, solve the two equation simultaneously. If they result to an answer then they intersect.
Answer:
15 cu ft
Step-by-step explanation:
Figure B is half of figure A,
So all the values are halved,
4/2=2
10/2 = 5
3/2 = 1.5
2 x 5 x 1.5 = 15
