Answer: 5
Step-by-step explanation:
weekday hours x*2
weekend hours y*10
x+y=26
2x+10y=220
----------------------
x=26-y
2(26-y)+10y=220
52-2y+10y=220
8y=220-52
8y=168
y=168/8
y=21
x=26-21=5
x=5
5: 25 degrees
8: 48 degrees
Still working on the other ones
Explanation
- for 5 we know that the straight line has a measurement of 180 degrees so we just add 125 and 30 to get 155 and 155 plus 25 is 180 degrees
- For 8 we know that the measurements of AED are 89 degrees and we know two other angles are 29 and 12 which make 41 if you add them and we know that 41 + 48= 89 which is what we wanted to get to
Answer:
4 donuts per minute/(donutes is that a typo?)
Step-by-step explanation:
if a bakery can make 60 donuts in 15 minutes, that is 60 donuts/15 minutes.
to reduce this fraction, the top and bottom can be divided by 15 to get 4 donuts/1 minute.
Step-by-step explanation:
This rule states that the same value can be added to both sides of an equation without interfering with the solving process of the equation
