Base on the question that said to write the letter of the statement or the reason in the said numbers in the question, and in my further analysis and research, the following are the answers:
Statements:
#1 C. x=15
#2 G. 3x-12=33
#3 L. 3x=45
#4 O. 3x+0=45
#5 <span>s. 3(x-4)=33
</span>
Reasons:
#1 R. Given
#2 F. Subtraction Property of Equality
#3 I. Division Property of Equality
#4 E. Addition Property of Equality
#5 <span>Distributive Property</span>
Answer:
200 miles
Step-by-step explanation:
1 cm = 50 miles
4 x 1 = 4 x 50 = 200
-7x^2 - 6x^2 + 3x + 5x - 5 + 2
-13x^2 + 8x - 3
Let n be a number of balls: n = 14
In one pan you have 8 balls: 8n
In the other pan you have the rest of balls (14 - 8 = 6) along with a <span>weight of 20 grams = 6n + 20
So the pans are balanced:
8n = 6n + 20
Now, just solve the equation:
8n - 6n = 20
2n = 20
n = 20/2
n = 10
So, you know that a ball weights 10 grams.</span>
