Hey there!
First, we will do the subtraction with the two like terms on the left. I know they're like terms because although they have different coefficients, they have the same variable.
We have:
2n=4
Divide both sides by 3 to get:
n = 2
Hope this helps!
Answer:
1.35kg
Step-by-step explanation:
450g : 6 people
x : 18 people
To get from 6 to 18, multiply by 3 so do the same to the other side
450 × 3 = 1350g
To convert from g to kg divide by 1000
1350 ÷ 1000 = 1.35kg
Answer:
slope of line ax + by = c is -a/b
so, slope of 7x +2y =5 is -7/2
Sin74 = Cos16
cause 16 + 74 = 90
Whenever the sum of two angles is equal with 90, the Sin of one is equal with the Cos of the other like :
Sin(30) = Cos(60)
and also
Tan(30) = Cot(60)
Answer:
x = -2
