Answer:

$3.98(estimated)

Step-by-step explanation:

3c (cake) + 2(2c - 11) (bread) = 5.87

3c + 4c - 22 = 5.87

7c - 22 = 5.87

7c = 5.87 + 22

7c = 27.87

Construct a quadratic equation whose roots are -2\3 and 5
Vladimir79 [104]
_Brainliest if helped!

Roots -2/3 and 5 Means X=-2/3 or X=5
Hence the equation would be
(X+2/3)(X-5)=0
(3X+2)(X-5)=0
3X^{2}  +2X -15X -10 = 0 

Answer : 3X^{2} -13X-10=0

Someone help me please?

The Answer

LCD = 12

Equivalent Fractions with the LCD

2/3 = 8/12

3/4 = 9/12

1/2 = 6/12

Solution:

Rewriting input as fractions if necessary:

2/3, 3/4, 1/2

For the denominators (3, 4, 2) the least common multiple (LCM) is 12.

LCM(3, 4, 2)

Therefore, the least common denominator (LCD) is 12.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

2/3 = 2/3 × 4/4 = 8/12

3/4 = 3/4 × 3/3 = 9/12

1/2 = 1/2 × 6/6 = 6/12

Hope This Was Helpful :D
