Answer:
x = 7 units
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
5 cm 3 cm
------------------ = ------------------------
(40 + 5) cm (3 + 2x + 10) cm
This simplifies to:
5 3
-------- = -----------
45 2x + 13
Solve for x. Cross-multiplying, we get:
10x + 65 = 135, or x = 7
So x = 7 units.
Answer:
16
Step-by-step explanation:
I counted each of the cubes and got 64.
Then I divided it by 4 since you need to divide it be 1/4.
once I divided 4 for 64 I got 16.
Answer:
the unit rate for the $100 option is 12.50
Step-by-step explanation:
100÷8=12.5 which is 12.50
Answer:
12
Step-by-step explanation:
Givens
Harpreet = x + 3
Sukhpreet = x
Komalpreet = 2*(x + 3)
Average Age = 15
Equation
[(x + 3) + x + 2*(x + 3) ] / 3 = 15 Multiply both sides by 3
Solution
3 [(x + 3) + x + 2*(x + 3) ] / 3 = 15 * 3 Combine
[(x + 3) + x + 2*(x + 3) ] = 45 Remove the brackets
x + 3 + x + 2x + 6 = 45 Combine like terms
4x + 9 = 45 Subtract 9 from both sides
4x + 9 - 9 = 45 - 9 Combine
4x = 36 Divide by 4
4x/4 = 36/4
x = 9
Answer
Harpreet is x+ 3 = 9 + 3 = 12
I would make both denominators the same, and the lowest one that works is 18. So I'd make 1/9 into 2/18, and 1/6 into 3/18. They already used these times so combine them to make 5/18 then subtract that from the total time they had (18/18) and you would get 13/18 they spent playing music.
