Answers

it is a linear simple equation, lets solve it step by step:
X + 3(X + 4) = 20
x + 3x + 3*4 = 20
4x + 12 = 20
4x = 20 - 12
4x = 8
x = 8/4
x = 2

Find the sum of 130 cm. And 50 mm.in meters

Answers

The sum of 130 cm and 50 mm. in meters is 1.35 m.

What is the unitary method?

The unitarymethod is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. The unitary method is a method by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

We are given the sum of 130 cm and 50 mm. in meters

130 cm = 130 / 100

= 1,3m

50 mm = 50 / 1000

= 0,05m

Therefore, the addition is;

1.3 + 0.05m = 1.35m

130 cm = 130 / 100 = 1,3m
50 mm = 50 / 1000 = 0,05m
1,3 + 0,05m = 1,35m

Laura wrote and solved the following expression to find the total number of beads Lina has if there are 6 beads in each packet. Find and correct Laura’s mistake7+4b = 11b
= 11(6)
=66

Answers

The number of beads lina has is 31

Laura made a mistake by adding the constant 7 and variable 4b

Solution:

Given that,

Laura wrote and solved the following expression to find the total number of beads Lina has

There are 6 beads in each packet

7+4b = 11b

= 11(6)

=66

From given,

Lina has a total of 7 + 4b beads

Given that, There are 6 beads in each packet

Substitute b = 6

7 + 4(6)

Simplify

7 + 24

Add

31

Thus, she has a total of 31 beads and not 66 beads

Laura made a mistake by adding the constant 7 and variable 4b

But a constant and variable cannot be added

Answer:

ya foot

Step-by-step explanation:

A rope 29 ft long rope is tied to the top of a flag pole. The rope is staked to the ground 21 ft away from the base of the pole. How tall is the flag pole?

Answers

Answer: 20 ft


Step-by-step explanation:

Given: The length of rope tied to the top of a flag pole=29 ft

The distance between base of the pole and the point on ground where the rope is stacked= 21 ft

Let x be the height of flagpole.

Now, we can see the figure that the given situation represents a right triangle

Where longest side= 29

By Pythagoras theorem of right triangle, the square of the longest side is equal to the sum of the squares of the other two sides.

29^2=21^2+x^2\n\Rightarrow\ x^2=29^2-21^2\n\Rightarrow\ x=841-441\n\Rightarrow\ x=400\n\Rightarrow\ x=√(400)\n\Rightarrow\ x=20

Hence, the height of flagpole = 20 ft.

It's like A2+B2=C2 so:
A2+B2=C2
A2+ 21(squared)=29(squared)
A2=441=841
A2=400
A=√(400)
A=20
