Answer:
4
Step-by-step explanation:
Firstly simplify your brackets...,
; 4(a^2 + 2b) = 4a^2 + 8b...then substitute it onto the bracket
; 4a^2 + 8b - 2b
; 4a^2 + 6b....,then substitute with the given values of a and b
; 4(2)^2)+ 6(-2)
; 16 - 12 = 4

Answer:
72, 96
Step-by-step explanation:
6 and 8 are already multiples of 2. The prime factorization of these numbers is ...
6 = 2×3
8 = 2³
The least common multiple of these numbers must have factors of 2³ and 3. That number is ...
2³×3 = 24
Multiples of 24 less than 150 are ...
24, 48, 72, 96, 120, 144
Of these, the values in the range of interest are 72 and 96.
Ravi could choose 72 or 96.
_____
72 = 2×36 = 6×12 = 8×9
96 = 2×48 = 6×16 = 8×12
(5,70) is the anwser. you have to graph it first then see where the lines meet your anwser should be where they both connect. i hope this helped.
Let
x------> amount of money Theo has
y------> amount of money Denise has
z------> amount of money Rudy has
we know that
x+y+z=$45-----> equation 1
x=5+y-----> equation 2
y=11+z----> equation 3
substitute equation 2 in equation 1
[5+y]+y+z=45-------> 2y+z=40-----> equation 4
y=11+z----> equation 3
2y+z=40-----> equation 4
resolves the equations system
using a graph tool
see the attached figure
the solution is
y=17
z=6
x=5+y----> x=5+17----> x=22
the answer is<span>
Denise has $17</span>
Answer:
John would give his brother $445
Step-by-step explanation:
The amount money that John give his brother would be his money minus for his brother money and divide by 2 so they can get the same money amount.
= ($2940 - $2050) / 2
= $890 / 2
= $445
So John would give his brother $445
Hope this help you :3
