Answer:
You can make 6 apple pies.
Step-by-step explanation:
90 - 9 - 15 = 66
66 - 6 = 60
You have 60 apples left after giving one to each of 9 teachers and 15 friends, and 6 to your grandma
Each pie takes 10 apples, so 60 ÷ 10 = 6
Wow. Ok, really simple, honestly. Because 3(5x) = 15x. (3*5)(3*x) = 3*5 = 15*3 = 45x. Therefore, 15x and 45x do not correspond to each other at all, meaning that 3(5x) is not equivalent to (3*5)(3*x)!!!
The range of the data is 12
5x - 5 = x + 15
add 5 to both sides
5x = x + 20
subtract x from both sides
4x = 20
divide both sides by 4
x = 5
Answer:
9.54 cm
Step-by-step explanation:
In triangle ABD, AD is the hypotenuse (longest side)
We know that according to Pythagoras theorem,
a^2+b^2=c^2
In the figure, c (10cm) and a (5cm) is given. So,
(5)^2 + b^2 = 100
25+b^2 = 100
b^2 = 75
So b is √75 = 8.66
Therefore BD is 8.66 cm
Now even BDC is a triangle
In it, the hypotenuse is missing but we know the value of other sides
so, in Pythagorean theorem,
a=4 (CD)
b=8.66 (BD)
c=x
Therefore,
(4)^2 + (8.66)^2 = x^2
16+74.99= x^2
x^2 = 90.99
x= 9.54 cm
Hope this helps!
