Answer:
x= 1 , y=4
Step-by-step explanation:
x-y= -3 => Equation 1
x+5y= 21 => Equation 2
<u>Substitut</u><u>ion</u><u> </u><u>Method</u><u>:</u>
<u>Substitu</u><u>te</u><u> </u><u>Equation</u><u> </u><u>1</u>=>
x=y-3 <= Equation 3
Put x=y-3 in Equation 2:
x+5y=21
( y-3)+5y=21
y-3+5y=21
6y-3=21
6y=21+3
6y=24
y=24÷6
y=4
Put y=4 in Equation 1:
x-y= -3
x-4=-3
x=4-3
x=1
Hope this helps :)
Answer:
Mean: 21
Median: 23
Mode: 27
Step-by-step explanation:
order from least to greatest:
1, 15, 18, 22, 23, 25, 27, 27, 31
mean: add all the numbers and divide by 9 bc thats how many numbers there are so that means the answer is
21
Median: to find the median you order the numbers from least to greatest and find out the middle number so in that case the median is 23
Mode: to find the mode you look to see what number is repeated multiple times, so the mode is 27
1 yard = 36 inches.
53 yards per hour x 36 inches per yard = 1908 inches per hour.
1 day = 24 hours.
1908 inches per hour x 24 hours = 45,792 inches per day.
Segment CF is parallel to segment BE because these segments are side by side and will have the same distance continuously between them. Therefore your answer would be,
Segment BE
∠AOF is the angle that is the supplementary angle to ∠FOD because these are two angles that sum up to 180°. hence, the answer is,
∠AOF
Answer:
34.
Step-by-step explanation:
All angles of a triangle combined equal 180, so if 1 angle measures 146, subtract 146 from 180. 180-146=34
