Answer: 8 hours.
Step-by-step explanation:
If the baby sleeps from 9pm to 5am, you will count. 9pm-12am is 3 hours of sleep. if you add 5 more hours, (12am+5 hours) it equals 5am. 5hours + 3hours is 8 hours.
Answer: 8 hours
Step-by-step explanation:
if you add 9+5 you will get 14 but if you count it like you would for hours it would be 9-10-11-12-1-2-3-4-5
b = w + 11
b = 3w − 15
Which of the following methods is correct to find Betsey's and Waldo's age?
Solve w + 11 = 3w − 15 to find the value of w.
Solve b + 11 = 3b − 15 to find the value of b.
Write the points where the graphs of the equations intersect the x-axis.
Write the points where the graphs of the equations intersect the y-axis.
Answer:
Option 1st is correct
Solve w + 11 = 3w − 15 to find the value of w.
Step-by-step explanation:
Here b represents the Betsey's age and w represents the Waldo's age
As per the statement:
Betsey is 11 years older than Waldo. Betsey's age is 15 years less than three times Waldo's age.
The system below models the relationship between b and w:
Equate these equations to solve for w, we have;
Add 15 to both sides we have;
Subtract w from both sides we have;
Divide both sides by 2 we have;
13 = w
or
w = 13 years
Substitute in b = w+11 we have;
b = 13 +11 = 24 years.
b = 24 years
Therefore. following methods is correct to find Betsey's and Waldo's age is:
Jackie buys a basket for $6, 2 pounds of apples for $3.50 per pound, and 2 pounds of oranges for $3.50 each per pound. The tax for the whole purchase is $1.
