(2x-2y)/(36-3x)
So now you sub in the variable into the equation
(* means multiply in this case because x would make it more confusing)
((2*7)-(2*2))/(36-(3*7))
= (14-4)/(36-21)
= 10/15
then you can reduce the fraction to 2/3
so the answer is 2/3 or if you want to put it in a decimal, 0.67
The equation for line l is y = 4
1/4 = 5/20
2/5 = 8/20
8/20 + 5/20 = 13/20 has been spent
Answer:
Crops are genetically modified to allow higher yields due to the production of molecules that are toxic to insect pests, but have no effect on animals and humans. ... Crops that are resistant to herbicides can also provide higher yield as the farmer can reduce the number of competing weed species in the field.
Step-by-step explanation:
Sin < C = 63/65 so m < C = 75.75 degrees
and tan B = 16/63 so m <B = 14.25 degrees
m < C + m<B = 75.75 + 14.25 = 90 degrees
Therefore m < A = 180-90 = 90
therefore the triangle is right-angled.
