Answer:
Step-by-step explanation:
3m + 7 = - 23
we pass the -7 to the right with a positive sign
3m = -23 - 7
we perform the sum of negative numbers
3m = -30
we pass the -3 to the right to divide
m = -30/3
we perform the division
m = -10
Answer:
The total amount of leftover lemonade is 6.
Step-by-step explanation:
First, you need to be aware that each person got a gallon after dividing a certain number by 6. Let the number be <em>x.</em>
So it means that x/6 = 1
Multiplying both sides by 6 gives x = 6.
Therefore, the amount of lemonade left over was gallons.
As a hint, read the word problems. Assign symbols or letters for the unknown terms. Collect the data. Last, formulate a linear equation and solve for the unknown quantity.
Answer:
x² + y² = 11
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
Here r =
⇒ r² = (
)² = 11, thus
x² + y² = 11 ← equation of circle
