Answer:
x = 13 ,y = 60
Step-by-step explanation:
Solve the following system:
{2 x + 6 y = 386 | (equation 1)
4 x + 4 y = 292 | (equation 2)
Swap equation 1 with equation 2:
{4 x + 4 y = 292 | (equation 1)
2 x + 6 y = 386 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + 4 y = 292 | (equation 1)
0 x+4 y = 240 | (equation 2)
Divide equation 1 by 4:
{x + y = 73 | (equation 1)
0 x+4 y = 240 | (equation 2)
Divide equation 2 by 4:
{x + y = 73 | (equation 1)
0 x+y = 60 | (equation 2)
Subtract equation 2 from equation 1:
{x+0 y = 13 | (equation 1)
0 x+y = 60 | (equation 2)
Collect results:
Answer: {x = 13 ,y = 60
I think its thousend not sure tho
Answer:
Jillene will spend<em> $345.60</em> in 6 months.
Step-by-step explanation:
To find the answer we will turn <em>24% into a decimal</em>. 24% ÷ 100 = <em>0.24</em>. Now <em>multiply 0.24 by $240</em> and we get<em> $57.60</em>. Because we are trying to find how much Jillene will spend in 6 months, we will <em>multiply $57.60 by 6</em>, which is $345.60. Therefore, <em>$345.60 is our answer.</em>
Well, your equation is linear and not quadratic. Is the -8x supposed to be squared?
Answer:
311.25 hours ; almost 13 days
Step-by-step explanation:
actually you will not able to drive a car all the way around the earth (the Pacific and Atlantic oceans are really big).
but According to the calculation it would take you around 311.25 hours ( almost 13 days) to drive the 24,900 miles around the circumference of the earth at its widest point (the equator).
because we know ,
t=s/v
=(24,900/80)hours [ s= the circumference of the earth]
=311.25 hours [v=Velocity]
