Solve a, b, c, & d please & I will mark you as Brainliest.

laila [671]

Answer:

Step-by-step explanation:

$a) -2x-3y=5\\-5x+3y=-40\\-7x=-35\\x=5, y=-5\\\\b)5x+6y=-14\\x-2y=10\\Considering\ equation\ 2,\\3(x-2y)=3(10)\\3x-6y=30\\Hence,\\5x+6y=-14\\3x-6y=30\\8x=16\\x=2, y=-4\\\\c) -3x+3y=21\\-x-5y=-17\\Considering\ equation\ 2,\\3(-x-5y)=3(-17)\\-3x-15y=-51\\Hence, subtracting\ both\ the\ equations\ we\ get,\\-3x+3y=21\\3x+15y=51\\18y=72\\y=4, x=-3$

d) Let the cost of one group lesson be x and one private lesson be y

$12x+2y=110\\10x+3y=125\\By\ multiplying\ the\ first\ equation\ with\ -1.5\ in\ this\ system\ we\ get,\\-1.5(12x+2y)=-1.5(110)\\-18x-3y=-165\\Hence,\ by\ adding\ both\ the\ equations\ we\ get,\\-18x-3y=-165\\10x+3y=125\\-8x=-40\\x=5,y=25$

the bakery bought 4 bags of flour containing 3.5 kg each. 0.475 kg of flour is needed to make a batch of muffins, and 0.65 kg is

GalinKa [24]

The left out amount of floor is $\boxed{\bf8.85\,\,{\text{kilogram}}}$ .

Further explanation:

The weight of one bag of flour is 3.5 kg.

The bakery bought 4 bags of flour.

Therefore, the total weight of 4 bags is calculated as follows:

$4\times\left({3.5\,\,{\text{kg}}}\right)=14\,\,{\text{kg}}$

The weight of flour needed for a batch of muffins is 0.475 kg.

Therefore, the weight of flour needed for 4 batches of muffins is calculated as follows:

$4\times\left({0.475\,\,{\text{kg}}}\right)=1.9\,\,{\text{kg}}$

The weight of flour needed for a loaf of bread is 0.65 kg.

Therefore, the weight of flour needed for 5 loaves of bread is calculated as follows:

$5\times\left({0.65\,\,{\text{kg}}}\right)=3.25\,\,{\text{kg}}$

So, the total weight of floor used in the process of making muffins and loaves of bread is calculated as follows:

$3.25\,\,{\text{kg+}}1.9\,\,{\text{kg}}=5.15\,\,{\text{kg}}$

Now, the weight of floor that is left out in the bag is calculated as follows:

$14\,\,{\text{kg}}-5.15\,\,{\text{kg}}=8.85\,\,{\text{kg}}$

Thus, the left out amount of floor is $\boxed{\bf8.85\,\,{\text{kilogram}}}$ .
