Answer:
4/8 is steeper than 3/10
Step-by-step explanation:
4 is half of 8 and in decimal form is 0.5. 3/10 in decimal form is 0.3. Therefore 0.5 is greater than 0.3, so 4/8 is considered to be steeper than 3/10.
Answer:
The numbers of boys in one grade are 60 .
Step-by-step explanation:
As given
In one grade of 150 students .
The ratio of boys to girls is 2:3.
Let us assume that the scalar multiple of boys and girls be x.
Thus number of boys = 2x
Number of girls = 3x
Than the equations becomes
2x + 3x = 150
5x = 150
x = 30
Thus number of boys = 2 × 30
= 60
Therefore the numbers of boys in one grade are 60
Distribute
remember a(b+c)=ab+ac
we can actually divide both sides by x
5(4x+8)=4(6x-10)
distribute
20x+40=24x-40
minus 20x both sides
40=4x-40
add 40 both sides
80=4x
divide by 4
20=x
Answer is so 100-8 is square root of 100
