4+2y<18 help please

Ulleksa [173]

Answer: 2

Step-by-step explanation:

We don't know what is the Y.

Then, 4 + 2y < 18 is:

6y < 18

If y=2, it'll make this equation true.

6*2 < 18

12 < 18.

So, Y=2

3(x+4)=5(x-2) I really need help i have no idea how to do it

Oksana_A [137]

answer: $x = 11$

work:

$3(x+4)=5(x-2)$ | distribute 3 and 5 into the parentheses.

$3x + 12 = 5x - 10$ | subtract 5x and move it over to 3x, and solve.

$-2x + 12 = -10$ | subtract 12 and move it over to -10, and solve.

$-2x = -22$ | divide by -2.

$x = 11$ | final answer.

hope this helps! ❤ from peachimin

The value of computer decreases with its age until it is worth nothing a computer that was purchases new for 0 years is worth 22

Georgia [21]

Answer:

$V(x) = -\frac{340}{3}x +2220$

$V(8) = 1313.3$

Step-by-step explanation:

Given

Let x represent years and V represents the value.

So, we have:

$(x_1,v_1) = (0,2220)$

$(x_2,v_2) = (6,1540)$

Solving (a): The linear function

First, we calculate the slope (m)

$m = \frac{v_2 - v_1}{x_2 - x_1}$

This gives:

$m = \frac{1540-2220}{6-0}$

$m = \frac{-680}{6}$

$m = -\frac{340}{3}$

The linear function is calculated using:

$v - v_2 = m(x - x_2)$

Where:

$(x_2,v_2) = (6,1540)$

$m = -\frac{340}{3}$

So, we have:

$v - 1540 = -\frac{340}{3}(x - 6)$

Open bracket

$v - 1540 = -\frac{340}{3}x +\frac{340}{3}* 6$

$v - 1540 = -\frac{340}{3}x +680$

Make v the subject

$v = -\frac{340}{3}x +680+1540$

$v = -\frac{340}{3}x +2220$

So, the function is:

$V(x) = -\frac{340}{3}x +2220$

Solving (b): When x = 8

Substitute 8 for x in $V(x) = -\frac{340}{3}x +2220$

$V(8) = -\frac{340}{3}*8 +2220$

$V(8) = -\frac{340*8}{3} +2220$

$V(8) = -\frac{2720}{3} +2220$

Take LCM

$V(8) = \frac{-2720+2220*3}{3}$

$V(8) = \frac{-2720+6660}{3}$

$V(8) = \frac{3940}{3}$

$V(8) = 1313.3$

Hence, its value after 8 years is 1313.3

Helpity helpityhelpity help

Marizza181 [45]

a) 24% said they wanted to learn french.

To find total number of students surveyed divide the number of students that want to learn French by the percentage:

12 / 0.24 = 50

There were 50 students surveyed.

b) 36% wanted to learn Spanish, multiply 50 by 36%

50 * 0.36 = 18

18 students wanted to learn Spanish.
