First you need to find the difference between the two years (2010-2005) which would be 5. Then find the difference in the number of students (12,250-12000) which would be 250. Finally divide 250 students by 5 years and you should get your answer of 50 students per year.

12 1/4- 1 1/2 >>> Convert fractions to decimals:
12.25- 1.5 = 10.75 >>> Convert decimals back to fractions:
10 3/4 >>> Add miles from the morning: 10 + 10 3/4 = 20 3/4 miles

Code.<br> -3x + 4y = -8<br> 8x - y = 16<br> Solving systems by substitution

LiRa [457]

Answer:

The solution to the system of equations is $\displaystyle \big(\frac{56}{29}, -\frac{16}{29}\big)$ .

Step-by-step explanation:

We are given a system of equations:

$\displaystyle \left \{ {{-3x+4y=-8} \atop {8x-y=16}} \right.$

We need to solve these by substitution, so we need to solve one equation for a variable and then substitute the value of that variable into the other equation.
After doing this and solving for the opposite variable, we need to insert this into the original equation and solve for the initial variable.
Therefore, to solve one of the equations, we will solve it to put it in slope-intercept form and solve for y. The easier equation to work with is equation two.

$\displaystyle 8x - y = 16\\\\-y = -8x + 16\\\\\frac{-y}{-1}=\frac{-8x+16}{-1}\\\\y = 8x - 16$

Now, we've solved for y. So, we can substitute this into either equation and solve for x.

$\displaystyle -3x + 4(8x -16)=-8\\\\-3x + 32x - 64 = -8\\\\29x - 64 = -8\\\\29x = 56\\\\\frac{29x}{29}=\frac{56}{29}\\\\x = \frac{56}{29}$

Now, we substitute our value for x into one of the original equations and solve for y.

$\displaystyle 8\big(\frac{56}{29}\big)-y=16\\\\-y = 16 - 8\big(\frac{56}{29}\big)\\\\-y=\frac{16}{29}\\\\\frac{-y}{-1}=\frac{\frac{16}{29}}{-1}\\\\y = -\frac{16}{29}$

Therefore, the solution to our system of equations is:

$\displaystyle \big(\frac{56}{29}, -\frac{16}{29}\big)$

5) Phillip earns $11.25 per hour. During Week 1, he worked h hours. During Week 2, he worked 8

Naddik [55]

Answer:

2,160 Hours

Step-by-step explanation:

Ok so usual i would split $540 in half so a number multiplied by two would end up as 540, and i got 270. So since each week we know Phillip earned $270 and $11.25 a hour, we can divide 270 by 11.25, which gives us $24, so that means h = 24, but on week 2 it says Phillip worked 8 hours more on week 2, so that gives us a equation of 8 x 11.25, which comes out to 90, so now we can move on to our final equation, 90 x 24, which equals 2160. Im so sorry if this is wrong
