Answer:

9

Step-by-step explanation:

open the bracket, you will have

5x-2x+13=40

collect like terms

5x-2x=40-13

3x=27

divide both side by 3

3x/3=27/3

x=9

Answer: 9

Step-by-step explanation:

5x-(2x-13)=40

Open bracket by -1

5x-2x+13. = 40

3x. = 40-13

3x. =. 27

Divide both sides by 3

x. = 27/3.

x. = 9

Given the table below, determine if the data represents a linear or an exponential function and find a possible formula for the
strojnjashka [21]
The answer is C) y=14(0.9)ˣ and it's an exponential function

PROOF 

Give to x the respective values of x & calculate y, using y = 14(0.9)ˣ

x         |       y
---------|---------
0         | 14(0.9)⁰ = 14
1         | 14(0.9)¹ = 12.6
2         | 14(0.9)² = 11.34
3         | 14(0.9)³ = 10.206
4         | 14(09)⁴ =  9.1845

A 210-N mass is suspended from a horizontal beam by two cables that make angles of 29 degrees and 53 degrees with the beam. Find
natta225 [31]

The tension in the cable is given by the newton's first law will be 163.622 N.

<h3>What is newton's first law?</h3>

The summation of the force is equal to zero.

The formula is given as

ΣF = 0

Where m is the mass of the body and a is the acceleration.

A 210-N mass is suspended from a horizontal beam by two cables that make angles of 29 degrees and 53 degrees with the beam.

Then the tension in the cable will be

Let T be the tension in the cable.

T sin 29° + T sin 53° – 210 = 0

On simplifying, we have

T (sin 29° + sin 53°) = 210

                             T = 163.622 N

More about the newton's first law link is given below.
