1 answer:

8 0

Three different fractions that are equivalent to 3/4 are 6/8, 9/12, and 12/16. I know that these fractions are equivalent because If you simplify them they all equal 3/4. I hope this helps!

In a field there are cows, birds, and spiders. Spiders have 4 eyes and 8 legs each. In the field there are 20 eyes and 30 legs.

Kitty [74]

Answer:

1 spider, 3 cows, 5 birds.

Step-by-step explanation:

Cows (C): 4 legs, 2 eyes.

Birds (B): 2 legs, 2 eyes.

Spiders (S): 8 legs, 4 eyes.

The number of legs and eyes are given, respectively by:

$30 = 4C+2B+8S\\20 = 2C+2B+4S$

Multiplying the second equation by -2 and adding it to the first one gives us the number of birds:

$30 -40= 4C-4C+2B-4B+8S-8S\\-10 = -2B\\B=5$

Rewriting the original equations with B =5:

$30 = 4C+2*5+8S\\20 = 2C+2*5+4S\\20 = 4C+8S\\10 = 2C+4S\\C=5-2S$

Since the number of cows cannot be negative, and both C and S must be odd numbers, the only possible value of S is 1:

$C=5-2S\\S=1\\C=3$

A health food store makes trail mix using dried fruit and nuts. The cost of the dried fruit is $2.50 per

Vinil7 [7]

Answer:

cost of dried fruit per pound=2.5 $/pound

cost of nuts per pound =2 $/pound

total cost=225$ =cost of dried fruit +total cost of nuts

To find the cost of dried fruit we need to multiply cost of dried fruit per pound and the number of bounds hence 2.5 x where x is the number of bounds

which is the total cost of dried fruit and consequently 2y is total cost of nuts where y is the weight of nuts in pound
