Answer:
The answer to your question is: x = 1, y = 4
Step-by-step explanation:
I'll change decimals to fractions
4.5 = 9/2
12.5 = 25/2
3.25 = 13/4
0.75 = 3/4
-9/2 x - 2 y = - 25/2 (I)
13/4 x - y = - 3/4 (ll)
Process
from (II) y = 13/4x + 3/4
Sunstitution -9/2x -2(13/4 x + 3/4) = - 25/2
-9/2 x - 13/2 x - 3/2 = -25/2
Multiply by 2 -9 x - 13 x - 3 = -25
-22 x = -25 + 3
-22 x = -22
x = 22/22
x = 1
y = 13/4 (1) + 3/4
y = 16/4
y = 4
It is a Kite because right now we are learning about that
Answer:
1, 2, 3, 6
Step-by-step explanation:
This questions is asking the GCF of 42 and 90. To find them, we have to find all their factors.
<u>42</u> <u>90</u>
1, 42 1, 90
2, 21 2, 45
3, 14 3, 30
6, 7 5, 18
6, 15
9, 10
Now we find the numbers that match up.
They both share 1, 2, 3, and 6 thus this is our answer
Number 18 the answer is -F
Number 19 the answer is -C
5/6 of an hour is 50 minutes. 2/5 of an hour is 24 minutes (1/5 of 60 is 12 times 2 is 24) 50 minus 24 is 26. There are 26 minutes left in the class.
