Answer:

(-4, 5)

Step-by-step explanation:

12x + 14y = 22

12x - 3y = -63

Rewrite the first equation. Multiply both sides of the second equation by -1 and write it below the first equation. Then, add the equations.

        12x + 14y = 22

(+)    -12x + 3y = 63

---------------------------

                 17y = 85

17y/17 = 85/17

y = 5

Substitute y with 5 in the first original equation and solve for x.

12x + 14y = 22

12x + 14(5) = 22

12x + 70 = 22

12x = -48

x = -4

Answer: (-4, 5)

We have 500 grams of a 10% salt solution. How many grams of water must be added to dulite the solution to form a 4% solution. Sh
lys-0071 [83]
Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add

50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750

750 grams of water

You have 7/8 of sour cream to make tacos if each tacos requires 1/16 cup of sour cream how many tacos can you make
vampirchik [111]
We need to find how many times 1/16 goes into 7/8. So, divide 7/8 by 1/16:
(7/8) / (1/16)
= (7/8) x (16/1)
= (7/8) x 16
= 7 x 16 / 8
= 7 x 2
= 14
The answer is 14.

(Intuitively, since 1/16 goes into 1/8 two times, it goes into 7/8 fourteen times.)
