Hi Lurch
1/2 divide by 5/8
1/2÷5/8
1/2*8/5 (multiply numerator together and denominator together )
8/10 ( divide the numerator by 2 and same for the denominator )
4/5
I hope that's help , please if you have question(s) ask !
Answer:
125
Step-by-step explanation:
(2^-6)(5)(2^3×2.5^2)
=(2^-6)(5)(2^6.5^2)
=(2^-6+6)5^1+2 [ in multiplication if base are same then power are added.
=2^0(5^3)
=1×(125)
=125
Answer:
<em>Bert is 11 years old and Max is 17 years old.</em>
Step-by-step explanation:
<u>System of Equations</u>
To solve the system of equations, we use two variables x and y. Let's make:
x = current age of Max
y = current age of Bert
x - 5 = age of Max five years ago
y - 5 = age of Bert five years ago
x + 1 = age of Max one year from now
y + 1 = age of Bert one year from now
According to the conditions of the problem, five years ago, Max was twice as old as Bert, thus:
x - 5 = 2(y - 5) [1]
It's also known a year from now, the sum of their ages would be 30:
x + 1 + y + 1 = 30 [2]
Operating and simplifying [1]:
x - 5 = 2y - 10
x = 2y - 5 [3]
Operating and simplifying [2]:
x + y + 2 = 30
x + y = 28 [4]
Substituting [3] in [4]:
(2y - 5) + y = 28
Simplifying:
3y - 5 = 28
3y = 33
y = 33/3 = 11
y = 11
From [3]:
x = 2*11 - 5
x = 22 - 5 = 17
x = 17
Max is 17 years old and Bert is 11 years old
Answer:
270
Step-by-step explanation:
250 x 8% or .08=20
250+20=270
