Preliminary work:
Following the BIDMAS order of operations, we can calculate part of it already, and that's the 2•4, which equals 8.
Therefore, the equation now reads:
8+x = y
x = 5:
8+5 = 13
13 ≠ 16
13 ≠ y
x = 4:
8+4 = 12
12 = 12
12 = y
Therefore, the pair is (4, 12)
Answer: Part A - C, Part B - 12 pieces
Step-by-step explanation:
<u>Part A:</u>
We know that 1/4 of Meredith's sub is bigger than 1/4 of Jim's sub, so we can set up an inequality.
Let Meredith's sub size = m; Jim's = j
Therefore, 1/4*m > 1/4*j
We can multiply both sides by 4:
m > j
Thus, the correct answer is C
<u>Part B:</u>
Since he had 1/4 of it left, that means he at 1 - 1/4 of it = 3/4 of his sub.
We can calculate the value of 3/4 * 16 = 12 pieces
5x = 4y - 3
The correct answer is D. 5x - 4y = -3
This is because standard form is the form ax + by = c, where a, b, and c are coefficients or constants of the variables x and y. Thus, Answer D (above) is the correct answer to this problem, as it is the only option that fits this.
Answer:
1: 18.75
Step-by-step explanation:
We multiply both sides by 5.
Answer: y = -1/3x -5 (4th option is correct)
Step-by-step explanation:
- The slope of a perpendicular line is opposite reciprocal --> -1/3
- Find b.
- -4 = -3(-1/3) + b
- -4 = 1 +b
- -5 = b
