Oliga [24]2 years ago
3 0

Step-by-step explanation:

1a. Just add both of them.

8x - 3 + 4x + 5 = 12x + 2

1b. We just subtract both of the functions.

(8x - 3) - (4x + 5) =

4x - 8

1c.

(8x - 3)(4x + 5)

32 {x}^{2}  + 28x - 15

1d.

\frac{8x - 3}{4x + 5}  = 2 - \frac{13}{4x + 5}

What is the solution of the equation 37=6x + 10 ?
frez [133]
First subtract 10 from both sides:

37 -10 = 6x + 10 -10
27 = 6x

Then divide both sides by 6

27 ÷ 6 = 6x ÷ 6

9/2 or 4.5 = x

To approach the runway, a pilot of a small plane must begin a 10 degrees descent starting from a height of 1983 feet above the g
ddd [48]
<h3>Answer:</h3>

2.2 miles

<h3>Explanation:</h3>

The mnemonic SOH CAH TOA reminds you that

... Sin = Opposite/Hypotenuse

We are given an angle (10°) and its opposite side length (1983 ft), and we are asked to find the hypotenuse (the straight-line distance from the plane to the runway).

... sin(10°) = (1983 ft)/distance

Multiplying by distance and dividing by sin(10°), we have ...

... distance = (1983 ft)/sin(10°) ≈ 11419.6 ft

We want to express this in miles, so we have ...

... 11419.6 ft = (m mi)×(5280 ft/mi)

... (11419.6 ft)/(5280 ft/mi) = m mi ≈ 2.163 mi

Rounding to tenths, the distance is ...

2.2 miles

_____

<em>Comment on the question</em>

The distance from the plane to the airport is different than the horizontal distance from the airport at which the descent must start. The latter distance is the "adjacent" leg of the triangle, so must be found using the tangent function. Rounded to tenths, it is 2.1 miles.

In the recipe,3/4 cup of white sugar makes 8 slices of pie .if you want 48 slices of pie, how much white sugar do you need
Mashutka [201]

Hi!

We will solve this using proportions, like this:

3/4 cup for 8 slices of pie

x cup for 48 slices of pie

_______________________

x = ((3/4)*48)/8

x = (3*48)/(4*8)

x = 144/32

x = 4,5

You need  4 1/2 cups of white sugar for 48 slices of pie.

Hope this helps!
