3C+2F=22
3C +2F-2F = 22-2F
3C = 22 - 2F
3C÷3 = 22÷3- 2F÷3
C= 22/3-2F/3
3C+2F=22
3C-3C +2F = 22 -3C
2F = 22 - 3C
2F÷2 = 22÷2 - 3C÷2
F= 11-3C/2

It is impossible to solve for 2 unknown variables in an equation. In order to solve this, you must think mentally.

What two numbers can you add to make 22?
A good example is 15 and 8.

Can 15 and 8 be divided into smaller numbers?
Yes.

15/3 = 5
8/2 = 4
   ^
   Notice how I'm dividing by the coefficient? *3*c and *2*f

So C can be 5 and F can be 4.

3(5) + 2(4) = 22
15 + 8 = 22
22 = 22

The people of Bridgetown wanted to build a bridge across a nearby river. Since they were poor swimmers, their master Trigonomos
VikaD [51]

Answer:

60.2 m

Step-by-step explanation:

Let x represent the width of the river.  The distance from the point across from the tree to the second point is 15 m.  The angle from this point to the tree across the river is 76°.

This makes the side opposite the angle x, the width of the river.  It also means the 15 m side is adjacent to this angle.

The ratio opposite/adjacent is the ratio for tangent; this gives us the equation

x/15 = tan(76)

Multiply both sides by 15:

15(x/15) = 15(tan(76))

x = 15(tan(76)) ≈ 60.2

kow [346]

Answer:

It goes into 20 because 4 is a factor of 20 on the multiplication chart

On a number line, A is at 5 and B is at 50. Point X is the midpoint. Point T is 2/3 of the way from X to B. Determine the coordi
Lemur [1.5K]

Number lines are used to represent points at regular interval.

The coordinate of point T on the number line is: 46.5

Given that:

A =5

B = 50

The coordinate of X at the midpoint is:

X = \frac{B + A}{2}

So, we have:

X = \frac{50+5}{2}

X = \frac{55}{2}

X = 27.5

Point T is at 2/3 from X to B.

The coordinate of T is calculated using:

T = X + \frac 23 (B - X + 1)

So, we have:

T = 27.5 + \frac 23 (55 - 27.5 + 1)

T = 27.5 + \frac 23 (28.5)

T = 27.5 + 19

T = 46.5

<em>Hence, T is located at 46.5</em>
