Answer: Yes! those are indeed apart of the fact family

Step-by-step explanation:

Notice that 9+5=14 and 5+9=14, thus the first two equations

show that if we add two numbers in any order, we get the same answer.

Notice that 14-9=5 and 9+5=14, so subtraction and addition are

related. Similarly 14-5=9 and 5+9=14

Notice that 14-9=5 and 14-5=9, so if you subtract one of the

members of the fact family from 14, you get the other.

What percent of 30 is 33
Llana [10]
Hi!

To solve this we can set up a proportion and cross multiply.

\frac{33}{30}  \frac{x}{100}

33 x 100 = 3300
3300/30 = 110

The answer is 110%

Hope this helps! :)

Does the point (9.5, 144) make sense in this context? Explain
Stolb23 [73]
No, (9.5, 144) does not make sense because there is no point of 9.5 and when you divide the ounces of water by the flavoring packets you end up with 12, and if you were to simplify that it would end up with 1 flavor packet and 12 ounces of water.

The lengths of the sides of a triangle are represented by 3 consecutive even integers. if the perimeter of the triangle is 72 fe
iris [78.8K]
P = a + b + c
P = 72
a = x
b = x + 2
c = x + 4

72 = x + x + 2 + x + 4
72 = 3x + 6
72 - 6 = 3x
66 = 3x
66/3 = x
22 = x

x + 2 = 22 + 2 = 24
x + 4 = 22 + 4 = 26

the sides of ur triangle are : 22,24,26 <==

Sav [38]

The mass lost by Darragh's coin is 0.164 g

<u>Solution:</u>

Given that Darragh has a Golden Eagle coin in his collection with a mass of 13.551 g

An uncirculated Golden Eagle coin has a mass of 13.715 g

To find: mass lost by Darragh's coin

From given question,

Darrangh has coin of mass = 13.551 g

Golden Eagle coin mass = 13.715 g

Darrangh's coin lost mass = 13.715 - 13.551 = 0.164

Thus mass lost by Darragh's coin is 0.164 g
