Answer:

x = 33

Step-by-step explanation:

4x-25+3x+25+2x-3+4x+3x+15 = 540

16x + 12 = 540

16x = 540 - 12

x = 528/16

x = 33

Four students spend $12 on school lunch at this rate find the amount 10 students will spend on the same school lunch

Andru [333]

Answer:

10 students would spend $30.

Step-by-step explanation:

In order to find this, start by looking for the cost per student. We can do this by dividing the overall cost by the number of students.

$12/4 students = $3 per student.

Now we take that unit rate and multiply by the new number of students.

$3 * 10 students = $30 total spent.

Line A has a slope of 3/2 and passes through the poin (3,3). Line B has a slope of -1/3 and passes through the point (-4,-2). At

ale4655 [162]

Answer:

The point of intersection is (-1,-3)

Step-by-step explanation:

Line A has a slope of 3/2 and passes through the point (3,3)

It is equation is:

$y = \frac{3}{2} (x - 3) + 3$

Line B has a slope of -1/3 and passes through the point (-4,-2).

It's equation is

$y = - \frac{1}{3} (x + 4) - 2$

To find their point of intersection, we solve the two equations simultaneously.

Let's equate the right hand sides:

$\frac{3}{2} (x - 3) + 3 = - \frac{1}{3} (x + 4) - 2 \\ \frac{3}{2} (x - 3) + \frac{1}{3} (x + 4) = - 5 \\ 9 (x - 3) + 2 (x + 4) = - 30$

Expand:

$9x - 27 + 2x + 8 = - 30$

$11x - 19 = - 30$

$11x = - 11$

$x = - 1$

Put x=-1 in the first equation:

$y = \frac{3}{2} ( - 1 - 3) + 3 = - 6 + 3 = - 3$

The point of intersection is (-1,-3)

a lacrosse team raised some money. the members used 74% of the money to buy uniforms, 18% for equipment, and the remaining $216

jok3333 [9.3K]

Answer:

Raised money = $2700

Step-by-step explanation:

Let x be the raised money.

Given:

The statement says the members used 74% of the money to buy uniforms, 18% for equipment,

Therefore, 74% + 18% = 92%

So the member used 92% of the money to buy uniform and equipment.

Remaining (100-92)% = 8% of the money for a team party is $216.

So, 8% of raised money = 216

8% $\times$ raised money = 216

$\frac{8}{100}\times x = 216$

$x=\frac{216\times 100}{8}$

$x=\frac{21600}{8}$

$x=2700$

Therefore, the raised money is $2700.
