Hello from MrBillDoesMath!
Answer:
3
Discussion:
34 + 2x = 40 => subtract 34 from both sides
(34-34) + 2x = 40 - 34 => as (34-34) = 0 and 40-34 = 6
2x = 6 => divide both sides by 2
x = 6/2 = 3
Check the answer:
Does 34 + 2x = 40 if x = 3 ?
Does 34 + 2(3) = 40 ?
Does 34 + 6 = 40 ? YES! so the answer checks.
Thank you,
MrB
You reduce the fraction which would be 9b-1/3=5b+ 5/3
Then you move the variable to the left side and change its sign 9b-5b-1/3=5/3 then move the constant to the right side 9b-5b=5/3+1/3
Then collect the terms 4b= 5/3 + 1/3 add the fractions 4b = 2
Divide both sides of the equation which is b= 1/2
Answer:
s= 10 + 2.50w
explanation:
the amount of money in your savings is equal to the initial $10 you had before you started saving 2.50 per week. weak week $2.50 is added to the savings. 2.50w can be seen as 2.50 times the amount of weeks. say you were 3 weeks into saving, you would do 10 + 2.50(3) to find the amount of money you have.
4(9+7) = 36+28 = 64
open the parentheses, then simplify.
All yuh have to do is double click the boxes and the correct number will pop up.
