They complete a 900-mile distance with their combined speed of (300+250=550) mph
Therefore, they meet after 900m/550mph=18/11h=1.6364h
Redville = r
Greenboro = 12r
Total of the two towns = 65
Now we can set up our equation.
r + 12r = 65
13r = 65
13r/13 = 65/13
r = 5
Redville gets 5 inches
1. Let the first integer be represented by: 2k
the second integer by: 2(k+1)
the third integer by: 2(k+2)
and the fourth by: 2(k+3)
Then, 2k + 2(k+2) = 2(k+3) - 6
2k + 2k + 4 = 2k + 6 - 6
4k + 4 = 2k
4 = -2k
-2 = k
Answer: -4, -2, 0, 2

2. Let the first integer be represented by: 2k+1
the second integer by: 2k+3
the third integer by: 2k+5
and the fourth by: 2k+7
Then, 2k+7 = (2k+1) + (2k+3) + (2k+5) + 2
2k + 7 = 6k + 11
-4 = 4k
-1 = k
Answer: -1, 1, 3, 5
Answer:
2 x^ (3/2)
Step-by-step explanation:
(x^2+x^2)
----------------
x^1/2
Combine like terms
2x^2
-----------
x^1/2
When dividing exponents with the same base, we subtract
a^b/ a^c = a^ (b-c)
2 * (x^2/ x^1/2) = 2( x^(2-1/2)) = 2 * x^ (3/2)
Answer:
There are 66 number of dogs in Miss Mulero's backyard.
Step-by-step explanation:
Let's set up equation for the given information.
Let there are 'd' number of dogs
and 'c' number of cats.
So, we can set up equation as
d+c=124
d=c+8
Let's solve the system of equations for 'd' and 'c'.
Substitute d as c+8 into the first equation then solve for 'c'
c+8+c=124
Combine like terms
2 c+8=124
Subtract both sides 8
2 c = 116
Divide both sides by 2.
c= 58
Plug in c as 58 into d=c+8
d=58+8
d=66
So, there are 66 number of dogs in Miss Mulero's backyard.
