Answer:
How does it need solved? By graphing? Substitution?
Step-by-step explanation:
Answer:
A) 4
Step-by-step explanation:
There are a couple of ways to get this but this is how I did it:
1. Multiply the second equation by 1/4 to get the same fraction for y as the one in the first equation
1/4 x + 1/8 y = 2
1/4 (1/3 x + 1/2 y = 4)
1/12 x + 1/8 y = 1
2. Subtract the first equation from the new equation
1/12 x + 1/8 y = 1
<u> - 1/4 x - 1/8 y = -2</u>
-1/6 x= -1
3. Divide both sides by -1/6
<u>-1/6</u> x= <u>-1</u>
-1/6 -1/6
x = 6
4. Substitute 4 in for x in the original equation:
1/4 (6) + 1/8y = 2
6/4 + 1/8y = 2
1/8y = 1/2
y = 4
Answer:
<h3>100</h3>
Step-by-step explanation:
Let the number we are looking for be x. If Jack divided 1,826.5 by the number to get a quotient of 18.265, to get the number we will solve the equation;
1,826.5/x = 18.265
Cross multiply
1826.5 = 18.265x
Divide both sides by 18.265
18.265x = 1826.5
18.265x/18.625 = 1826.5/18.625
x = 100
Hence Jack divide 1,826.5 by 100 to get a quotient of 18.265
You dont have a picture so idk the answer but its most likely E if thats an answer choice.
The answer to the variable b is 708.4
