X2+y2=65............1
X2-3y=37..............2
÷both equation. 1 by 2
X+y=32,5
X=32,5-y......... 3
Sub 3 in 2
(32,5-y)2-3y=37
65-2y-3y=37
65-5y=37
-5y=37-65
-5y= - 28 divide both sides by - 5
Y=5,6........ 4
Sub 4 in 3
x=32,5-y
=32,5-5,6
=26,9
Hope it's the way you wanted it
Answer:
Klog earned $135.45 altogether.
Step-by-step explanation:
<u>Hours</u>
<em>Monday - Friday : 5 days / 3.5 hours</em>
<em>Saturday : 1 day / 4 hours</em>
3.5 · 5 + 4
= 17.5 + 4
= 21.5
<u>Money</u>
<em>$6.30 per hours / 21.5 hours</em>
6.30 · 21.5
= $135.45

All factors of 12 are {-12, -6, -4, -3, -2, -1, 1, 2, 3, 4, 6, 12}, so x is one of these numbers.
t is a prime, so t∈{2, 3, 5, 7, 11, 13, 17, 19, 23....}
A) t/x cannot be 1/12, because 1 is not a prime. NOT POSSIBLE
B) 1/4 = 3/12 ...... 3 is a prime and 12 is a factor of 12. POSSIBLE
C) 1/2= 3/6 .....3 is a prime and 6 is a factor of 12. POSSIBLE
D) 1 = 2/2....... 2 is a prime and 2 is a factor of 12. POSSIBLE
E) 2 = 2/1 ....... 2 is a prime and 1 is a factor of 12. POSSIBLE
Answer: A
