You can do this a number of ways.
The first way is to set up a proportion. That's very formal, and is most respected.

Proportion.
x / 60 = 1 / 10 The proportion is reduced by a factor of 10. Cross Multiply.
10 * x = 60 * 1 
10x = 60  Divide by 10
x = 60/10 
x = 6

Multiply by the scale factor.
Beginning number * scale factor = Final result.
60 * 1/10  = Final Result
60 * 1 / 10 = Final Result
Final Result = 6

This method words even when the numbers are quite complicated.

Three points, A, B, and C exists in space such that B is "between" A and C. It is known that AB=7, BC=4, and AC=9. Are points A,
LenKa [72]
Two or more points are said to be collinear if they lie on the same straight line.

Given a straight line XY, with a point P on the straight line between point X and Y, then
XP + PY = XY

From the question, it was given that AB = 7 and BC = 4, so if A, B, C are colinear, then
AB + BC = AC
i.e. 7 + 4 = 11

But, from the equation, AC = 9.

Therefore, points A, B and C are not collinear.

The graph of f(x) is shown. Estimate f(–3).
Aneli [31]

You have to look for -3 on the x axis, and then proceed vertically (in this case upwards) until you meet the graph.

We land about 1/2 square above the 12 mark on the y axis. Since one square is 1/2 unit, a half square would be 1/4 unit.

So, we can estimate f(-3)\approx 12.25

Can anyone help me with these questions please? 5 + 2x = 19 and also 4x + 3 = 27
Elza [17]

Answer:

x= 7

x=6

Step-by-step explanation:

5+2x=19

Subtract 5 from both sides

so...

2x=14

then divide by two to isolate the x

so..

x=7

4x+3=27

Subtract 3 from both sides

so...

4x=24

then divide by 4 to isolate the x

so....

x=6
