Why Aren’t the expressions 5+5+5+ X plus X plus X plus X equivalent

WITCHER [35]

I don’t know what you mean. Are you talking about the fact that x is an unknown number or the fact that there are 4 “terms” in one and 3 in the other?

What is the solution to the equation 5a^2 - 44 = 81

AveGali [126]

Answer:

Step-by-step explanation:

5a^2 - 44 = 81

5a^2 = 81 + 44 {add 44 both the sides}

5a^2 = 125

a^2 = 125/5 {divide both sides by 5}

a^2 = 25

a^2 = 5*5

a = ±5

Madelyn is 1.85 meters tall. At 12 noon, she measures the length of a tree's shadow to be 39.75 meters. She stands 34.9 meters a

Margaret [11]

The relationship between her height and the tree's is an illustration of ratios and proportions

The height of the tree is approximately 2.11 meters

Her height is represented as:

$\mathbf{h =1.85}$

At 12 noon, the length of the tree's shadow and her distance from the shadow are given as:

$\mathbf{D =39.75}$

$\mathbf{d =34.9}$

To calculate the height (H) of the tree, we make use of the following equivalent ratios

$\mathbf{H : h =D : d}$

So, we have:

$\mathbf{H : 1.85 =39.75 : 34.9}$

Express ratio as fraction

$\mathbf{\frac{H }{ 1.85 }=\frac{39.75 }{ 34.9}}$

Multiply both sides by 1.85

$\mathbf{H=1.85 \times \frac{39.75 }{ 34.9}}$

$\mathbf{H=2.11}$

Hence, the height of the tree is approximately 2.11 meters

vesna_86 [32]

Answer:

Step-by-step explanation:

The set made up of odd numbers and multiples of 7 is given as;

{-21.-7. 7. 21)

Multiples of 7 are usually those numbers where 7 is factor.

Odd numbers are numbers that cannot be divide by 2.

So, the most fitting answer is B.
