I'll use substitution. I think that's the easiest.

11x + 8y = -16
x = 4y + 10

Plug in: 11(4y + 10) + 8y = -16

Simplify: 44y + 110 + 8y = -16

Simplify: 52y + 110 = -16

Subtract from both sides: 52y = -16 - 110

Simplify: 52y = -126

Divide: y = -126/52

Simplify: -2.42 or -2 and 11/26'

I could continue to solve for x, but we can see your options and D is the only one with this value for y.

One of the sides of a parallelogram has the length of 5 in. can the lengths of the diagonals be: 4 in and 6 in?
abruzzese [7]

Answer:

Yes, the diagonals could be 6 and 7 in. In a parallelogram, only the opposite sides of the parallelogram are congruent.

Step-by-step explanation:

In a parallelogram, the diagonals bisect each other, so you can set the labeled segments equal to one another and then solve for . \displaystyle 20 - 3x = 2x - 4 \rightarrow 24 = 5x \rightarrow 4.8 = x. Then, substitute 4.8 for in each labeled segment to get a total of 11.2 for the diagonal length.

The world produces about 3.9 billion tons of food every year. Of that amount, approximately 2.6 billion tons is consumed each ye
konstantin123 [22]
Total food produces => 3.9 billion

total consumed = 2.6 billion

remaining = 1.3billion tons .

therefore %ve of food wasted = 1.3/3.9×100 = 33.33%

hence 33.33% food waste every year .

option b) is right answer .
