Answer:
Megan needs 1 and 1/3 cup of almonds to make 9 cups pf trail mix.
Step-by-step explanation:
I'm not good with ratios and fractions so I drew an illustration.
I found out that 1/6 of almond cup is equivalent to 1 cup of trail mix.
So I add 2/3+2/3+1/6
I changed the denominator of 2/3 to 6 and divided 6 by 3 then multiply the answer by 2, then the product will be the numerator.
(6÷3) = 2 (2x2) =4
So, 4/6+4/6+1/6= 9/6
Simply the sum and it will be 1 and 1/3.
Answer:
Step-by-step explanation:
1). x² - 8x
To convert this expression into a perfect square trinomial,
x² - 2(4x) + 4² = (x - 2)²
Therefore , 4² = 16 should be added.
Option (4) is the answer.
2). x² + 2x = 3
x² + 2(1)(x) = 3
x² + 2(1)(x) + 1 = 3 + 1 [By adding 1 on both the sides]
(x + 1)² = 4
x + 1 = ±2
x = -3, -1
Option (1) is the answer.
3). 3x²- 18x = 21
x² - 6x = 7
x² - 2(3x) = 7
x² - 2(3x) + 3² = 7 + 3²
(x - 3)² = 7 + 9
(x - 3)² = 16
x - 3 = ±4
x = -1, 7
Solution
The general form of the equation is y = mx + b, where m is the slope and b is the y-intercept.
Given: m = 8/7 and b = -3
Plugin the given values into the formula.
y = 8/7x - 3
The answer is y = 8/7x - 3
Thank you :)
