There are 60 minutes in 1 hr, so in 1 hour, her heart beats 65(60)
24 hours in 1 day, so it beats in 1 day 24(65 * 60)
365 days in 1 year, so it beats in 1 year, 365(24 * 65 * 60)
how much will it be in 10 years then? 10(365 * 24 * 65 * 60).
X= 2 bed rooms
y= 3 bed rooms
Adding x+y will equal the total number of rooms (40). Multiplying (2 beds * the number of 2 bed rooms) and (3 beds * the number of 3 bed rooms), and adding those together, will equal the total number of beds (92).
x+y= 40 rooms
2x+3y= 92 beds
Solve for one variable in equation one and substitute it in equation two.
Solve for one variable:
x+y= 40
Subtract y from both sides
x= 40-y
Substitute (40-y) in for x in equation two:
2x+3y= 92
2(40-y) +3y= 92
80-2y+3y=92
Subtract 80 from both sides
y= 12 three bed rooms
Substitute 12 in for y in either equation:
x+y= 40
x+12= 40
x= 28 two bed rooms
Check work:
2x+3y= 92
2(28)+3(12)= 92
56+36= 92
92= 92
Hope this helps! :)
To find the price per pound, simply add 0.65 + 0.75 then divide.
0.65 + 0.75 = 1.40 13.65 / 1.40 = 9.75
Danny paid $9.75 per pound!
Step-by-step explanation:
x+30°=4x(inscribed angle is equal to its arc)
4x-x=30°
3x=30°
x=30/3
x=10°
hope it helps.
