KEVIN'S GAS TANK IS 1/6 FULL. AFTER HE BUYS 14 GALLONS OF GAS, IT IS 3/4 FULL. HOW MANY GALLONS CAN KEVIN'S TANK HOLD?

Reika [66]

$\frac 1 6 t + 14 = \frac 3 4 t$

$14 = (\frac 3 4 - \frac 1 6)t = (\frac 9{12} - \frac{2}{12}) t = \frac {7}{12} t$

$t = \frac{12}{7} (14) = 24$

Answer: 24 gallons

Check: (1/6)24=4, 4+14=18, 18/24=3/4, good

Draw the graphs of the lines below on the same grid to find the coordinates of the point of

Amanda [17]

Answer:

(2,2) is the solution of the given lines.

Step-by-step explanation:

Given that,

y = x ..(1)

y = 3x-4 ...(2)

We need to find the coordinates of the point of intersection.

From equation (1) and (2).

x=3x-4

4 = 3x-x

4 = 2x

x = 2

Also,

y = 2

<h3>Hence, the coordinates of the point of intersection is (2,2).</h3>

11-3(x+2)<br> Expand and simplify

statuscvo [17]

Answer:

5-3x

Step-by-step explanation:

To expand this, we start with the distribution of -3 into the parentheses containing x+2

This leaves us with

11-3x-6

From here, simplifying involves combining like terms. The only like terms we have are the constant values 11 and -6

We combine them by subtracting 11-6 to get 5.

This leaves us with our answer,

11-6-3x

<u>5-3x</u>

An alternate way of writing this would be

<u>-3x+5</u>

But this would only be required if we were asked to express the answer in decreasing degree, so don't worry about that for now

Can someone help me find the length of b of the unknown side in this triangle? Thanks! :)

creativ13 [48]

Answer: 4

Step-by-step explanation:

Using pythagoras theorem =>

b= $\sqrt{c^2-a^2$

b= $\sqrt{5^2-3^2}$

b= $\sqrt{25-9}$

b= $\sqrt{16}$

b=4
