Answer:
- 1
Step-by-step explanation:
Using the order of operations PEMDAS ( parenthesis, exponents, multiplication, division, addition, subtraction )
Given
17 - 6 × 10 ÷ 2 + 12 ← perform multiplication
= 17 - 60 ÷ 2 + 12 ← perform division
= 17 - 30 + 12 ← perform addition/ subtraction from left to right
= - 13 + 12
= - 1
You want y? One way to get y alone would be to mult. all 3 terms by (7/5):
(7/5)(5/7)y = (7/5)*3 - (7/5)(-1/5). This simplifies to:
y = 21/5 * 7/25, or y = 147 / 125.
You could check this using decimal fractions:
y = 4.20 * 0.28 = 1.176 = 147 / 125.
That’s easy. He just has to score lower than the lowest athlete’s time. Since the lowest time is 9.75 seconds, any time lower than that will win him the competition.
Well the graph with the highest slope means it is more expensive.
The slope of the red apples = 2x.
We need the slope of the green apples.
*solving*
The slope of the green apples = 3/2x
Because 2 > 3/2, red apples are more expensive
