Answer:

Step-by-step explanation:

In this problem, x1 is -3, y1 is 8, x2 is 9, and y2 is -7. From the ratio 2:1, a = 2 and b = 1. Use these formulas to find the x and y coordinates of the point on the directed line segment:

For the x coordinate:

\frac{bx_1+ax_2}{a+b}

For the y coordinate:

\frac{by_1+ay_2}{a+b}

Filling in accordingly for x:

\frac{1(-3)+2(9)}{3} which simplifies down to 5;

for y:

\frac{1(8)+2(-7)}{3} which simplifies down to -2

Write these down because they are hard to remember but so simple to use!!!

0.156x = 76.252 - x<br> solve for x
Tomtit [17]

Answer:

≈ 488.8

Step-by-step explanation:

So we wanna find x for 0.156x = 76.252;

What we have to do is to divide both sides of the equation by 0.156 to isolate the variable

If you are allowed to use a calculator then you can get the answer:

It equals around 488.8

If you want to solve it by hand, you can multiply both by 1000 to get:

76252 divided by 156.

I dont understand this
Ganezh [65]

Answer:

x = 8.3 is the value of x.

Step-by-step explanation:

Given:

Let Δ ABC be a Right angle Triangle at ∠ C = 90°

AB = x

BC = 6

m∠ B = 44°

To Find:

x = ?

Solution:

We apply Cosine Rule

{tex}\cos B = \frac{\textrm{side Adjacent to angle B}}{Hypotenuse}  \\{/tex]

Substituting the given values we get

\cos B = \frac{BC}{AB}\\\\\cos 44 = \frac{6}{x}\\\\0.719=\frac{6}{x}\\\\\therefore x=\frac{6}{0.719} \\\\\therefore x=8.3......(nearest\ tenth)

The value of x is

x = 8.3
