$\\ \sf\Rrightarrow y-1=\dfrac{2}{3}(x+1)$

$\\ \sf\Rrightarrow -3-1=\dfrac{2}{3}(a+1)$

$\\ \sf\Rrightarrow -4=\dfrac{-2(a+1)}{3}$

$\\ \sf\Rrightarrow -2(a+1)=-4(3)$

$\\ \sf\Rrightarrow -2(a+1)=-12$

$\\ \sf\Rrightarrow a+1=\dfrac{-12}{-2}$

$\\ \sf\Rrightarrow a+1=6$

$\\ \sf\Rrightarrow a=6-1$

$\\ \sf\Rrightarrow a=5$

Five-sixths of the boats in the marina are white, 2 5 of the remaining boats are blue, and the rest are red. If there are 12 red

Inga [223]

Answer: There are 120 boats in the marina.

Step-by-step explanation:

Let's suppose that there are N boats

We know that 5/6 of them are white, then we have: (5/6)*N white boats.

The remaining is: N - (5/6)*N = (1/6)*N

We know that 2/5 of the remaining are blue, then we have:

(2/5)*(1/6)*N blue boats

And the rest are red, the rest is:

(1/6)*N - (2/5)*(1/6)*N = (3/5)*(1/6)*N

Then we have (3/5)*(1/6)*N red boats.

And we know that there are 12 red boats, then:

(3/5)*(1/6)*N = 12

Now we can solve this for N, which is the total number of boats in the marina.

N = 12*(6)*(5/3) = 120

There are 120 boats in the marina.

T |3x° -- V W Find the measure of angles T and V. mZT= o mZV=

SIZIF [17.4K]

Answer:

∠T = 67.5

∠V = 22.5

Step-by-step explanation:

Angles of a triangle rule: The angles of a triangle should add up to equal 180

That being said we create an equation to solve for x

180 = 3x + x + 90 ( there is a right angle indicated by the square at the bottom right of the triangle. A right angle has a measure of 90 degrees so that is where the 90 cam from )

Now that we've created an equation we want to solve for x

180 = 3x + x + 90

step 1 combine like terms

3x + x = 4x

now we have 180 = 4x + 90

step 2 subtract 90 from each side

180 - 90 = 90

now we have 90 = 4x

step 3 divide each side by 4

4x / 4 = x

90 / 4 = 22.5

we're left with x = 22.5

Now we want to find ∠T and ∠V

To do so we replace x in the given expressions with 22.5

for ∠V

∠V = x so ∠V = 22.5

for ∠T

∠T = 3x

* replace x with 22.5 *

3 (22.5) = 67.5

Hence ∠T = 67.5

Need help on Part A!

3241004551 [841]

Let k represent the cost of supplies, b the number of bottles, and c the number of cans. You know that the total cost is found by adding the number of bottles multiplied by the price of each to the number of cans multiplied by their unit price. (This is the computation performed anytime you purchase something.)

$\boxed{k}=\underline{3.99}\boxed{b}+\underline{1.50}\boxed{c}$

There are no constants in this equation.
