First you create a proportion (30/100=x/120). After you solve this, next you subtract this answer from 120. Then create a proportion for 40% (40/100=x/120). Then add this number to the first answer you got when you subtracted the answer from your first proportion from 120.
Answer:
A)(7,-9)
Step-by-step explanation:
we know x=7
so put it in the equation
y= -2(7)+5
y=-9
we always put the x coordinate first and then the y coordinate so the answer is (7,-9)
Answer:
10
Step-by-step explanation:
substitute the given values into the expression
2(x + z) - y
= 2(6 + 3) - 8
= 2(9) - 8
= 18 - 8
= 10
K.E=0.5mv^2
GPE=mgh
The child has both K.E and GPE
g is taken as 9.81
