Changing those words into an equation, we get:
7+3x = 19
Subtract both sides by 7
3x = 12
Divide both sides by 3
x = 4
That number is 4. Have a nice day! :)
5= (6+4)x
5= 10x
5= 10x then divide by 10 to get the variable by itself
__ ___
10 10
.5 = x you can use .5 or 1/2
hope this helps!
:)
Firstly, use the distributive property of multiplication (A(B + C) = A×B + A×C) on -2(q - 5) and -3(q + 1): 
Next, apply the addition property of equality (whatever you add to one side you have to add the same quantity to the other), and add 3q on both sides: 
Lastly, apply the subtraction property of equality (whatever you subtract on one side you have to subtract the same amount on the other side), and subtract 10 on both sides. <u>Your final answer will be
</u>
Answer: 0.5 and 0.25
Step-by-step explanation: You have to divide the number by 2 to get to the next term.
This is essentially asking how many different ways to partition 6 into 3 segments.
I am assuming "no ball in a box" is not allowed.
6 can be partitioned as
(4,1,1), (3,2,1), and (2,2,2)
So, calculate each partition, we get
(6 choose 4) + (6 choose 3)*(3 choose 2) + (6 choose 2) * (4 choose 2)
= 15 + 20*3 + 15*6
