Answer:

About 4%

because 5 of 5.2 is about 96% so 100% - 96% = 4%

Answer:

4%

Step-by-step explanation:

vA = actual value

vE = expected value

percent error = ((vA - vE) / vE) x 100

((5.2 - 5) / 5) x 100 = 4

4%

I NEED HELP PICTURE PROVIDED!

Sav [38]

Question 2:
The answer is 21
The two angles are vertically opposite, which makes them equal and also means we can make an equation:
4x - 4 = 3x + 17
- 3x
x - 4 = 14
+ 4
x = 21

Question 3:
The answer is 23
Again, the angles are vertically opposite, so we can make them equal each other:
5x - 53 = 3x - 7
- 3x
2x - 53 = -7
+ 53
2x = 46
÷ 2
x = 23

I hope this helps!

What is the value of x in the equation 2x + 1/2x + 2(1+x) = 29?

erica [24]

Answer:

<h2>x = 6</h2>

Step-by-step explanation:

$2x + \frac{1}{2} x + 2(1 + x) = 29$

Multiply through by 2

That's

$4x + x + 4(1 + x) = 58$

<u>Expand</u>

That's

5x + 4 + 4x = 58

9x = 58 - 4

9x = 54

Divide both sides by 9

That's

$\frac{9x}{9} = \frac{54}{9}$

We have the final answer as

<h3>x = 6</h3>

Hope this helps you

1. JP Construction is building a rectangular children's wading pool for the local community center. The pool will be 4.5 meters

Bond [772]

Answer:

$x\leq 1.78$

Step-by-step explanation:

We are given that

Width of pool, b=4.5 m

We have to find the inequality which represents the possible lengths of the wading pool.

Let x be the length of wading pool

We know that

Area of rectangle= $length\times breadth$

According to question

Using the formula

$4.5x\leq 8$

Divide by 4.5 on both sides we get

$x\leq\frac{8}{4.5}$

$x\leq 1.78$
