Solve for a
3b=10b-49
Solve for b
Answer:
The first answer is a = 10, The second answer is b = 7
Step-by-step explanation:
Equation 1: 5a = a + 40
To solve for a, you want to isolate a on one side of the equation. You can do this by subtracting "a" from both sides of the equation:
5a - a = a - a + 40
This simplifies to:
4a = 40
Now, divide both sides by 4 to solve for a:
4a/4 = 40/4
a = 10
So, a = 10.
Equation 2: 3b = 10b - 49
To solve for b, you want to isolate b on one side of the equation. First, let's get the "b" terms on one side by subtracting 10b from both sides:
3b - 10b = 10b - 10b - 49
This simplifies to:
-7b = -49
Now, divide both sides by -7 to solve for b:
(-7b) / (-7) = (-49) / (-7)
b = 7
So, b = 7.

Answer:
50 oranges
Step-by-step explanation:
Convert the measurements for them to be the same ie 4kg to g
1kg=1000g. 4kgx1000=4000g
4000g is the mass of all oranges
1 orange=80g
? =4000g that is 4000/80
=50 oranges
Answer:
50 oranges
Step-by-step explanation:
Since each orange is measured in grams, we convert the 4 kg to g to start.
4 kg is equal to 4000 g.
Each orange weighs 80 g, so we divide 80g into 4000g.
80 divided by 4000 equals 50.
50 oranges are in the box.

We can see here that there are 72 months in 6 years. It is gotten by multiplying 12 months by 6 years.
A month is a unit of time commonly used in calendars to divide a year into shorter periods. It is based on the approximate time it takes for the Moon to orbit the Earth, which is roughly 29.5 days. To account for the varying lengths of months, the Gregorian calendar, the most widely used civil calendar, has months of different durations: 28, 30, or 31 days.
To calculate the number of months in a given number of years, you multiply the number of years by 12 since there are 12 months in a year. Therefore, 6 years multiplied by 12 months equals 72 months.
