Answer:
uh its 5
Step-by-step explanation:
This is cross multipication. Multiply 117 times 36 together for that you would use a calculator. You get 4221. Next step is to multiply x and 12 together that would be 12x.
4221= 12x
Divide by 12 on both sides:
x= 351
351 is # of trouts in the lake .
Answer:
<h2>The solution is x = 2 and y = 1.</h2>
Step-by-step explanation:
The given equations are x = 4 - 2y.......(1) and 3x - 2y = 4......(2).
Putting the value of the first equation in the second, we get
3x - 2y = 4
or, 3(4 - 2y) - 2y = 4
or, 12 - 6y - 2y = 4
or, 8y = 8
or, y = 1.
Putting the value of y in the first equation, we get x = 4 - 2 = 2.
64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as
4 x 16 + 4 x 7
and then use the distributive property to rewrite it again as
4 x (16 + 7)
