Answer:
165 cards left
Step-by-step explanation:
x + 221 = 386
-221 from both sides
x = 165
Answer:
y = -⅔x + ²²/₃
Step-by-step explanation:
1. Calculate the slope of EF
Assume E is at (-2, 5) and F is at (1, 3).
m₁ = (y₂ - y₁)/(x₂ - x₁) = (3 - 5)/(1 -(-2)) = -⅔
2. Calculate the slope of the parallel line
m₂ = m₁ = -⅔
3. Calculate its y-intercept
y = mx + b
6 =-⅔(2) + b
Simplify
6 = -⁴/₃ + b
Add ⁴/₃ to each side
b = 6 + ⁴/₃ = ¹⁸/₃ + ⁴/₃ = ²²/₃
The y-intercept is at (0,²²/₃).
4. Write the equation for the line
y = -⅔x + ²²/₃
The diagram shows EF in red. The parallel line in black passes through (2, 6) with a y-intercept at (0,²²/₃).

Answer:
I have no clue as to what the options were, but the answer is 61 and three-fifths.
Step-by-step explanation:
<em>Well, the fraction options were a little distorted, so I'll work it out anyway.</em>
<em />
7 • 8 4/5
7(8 + 4/5)
<em>7 • 8 is 56, and 7 • 4/5 is 28/5.</em>
56 + 28/5
<em>28/5 as a mixed-number fraction (I think that's what it's called) is 5 3/5.</em>
56 + 5 + 3/5
61 + 3/5
61 3/5 (61 and three-fifths)
There!
<em>(Sorry about not getting the options...)</em>
Answer:
The top is (-2 , 2) and the bottom is (4 , -2)
