ANSWER
r = 10
EXPLANATION
To solve for r first we have to put r in the numerator. To do that, we have to multiply both sides of the proportion by r:
Now, we have to multiply both sides by 35:
And finally divide both sides by 28:
Answer:
D. 14x - 4
Step-by-step explanation:
P = 2(L + W)
P = 2(4x + 5 + 3x - 7)
P = 2(7x - 2)
P = 14x - 4
So, there are two equations.
5a + 3c = 30
a + c = 8, therefore, a = 8 - c
5a + 3c = 30
5(8 - c) + 3c = 30
40 - 5c + 3c = 30
-2c = -10
c = 5 , So a = 3
Total number of possible outcomes:12
Number of favourable outcomes:2( since only two numbers divisible by 5 in that range are 5 and 10)
The possibility that you'll pick a number divisible by 5 is 2/12 or 1/6
Hope that's what you're looking for since you didn't specify.
Answer:
A pound of cat food will weigh 6.5 pounds
Step-by-step explanation:
Firstly, we need to get the value of x. Thus, let’s solve the equation at hand;
x + 3x/2 = 32.5
x + 1.5x = 32.5
2.5x = 32.5
x = 32.5/2.5
x = 13
Now from the question, we are made to know that a pound of cat food measures half of what a pound of dog food measures
Since we calculate a pound of dog food to weigh 13 pounds, a pound of cat food will weigh = 13/2 = 6.5 pounds
