George bought 7 quarts of cleaning fluid: x quarts at $3.00 per quart & y quarts at $2.00 per quart. Find x & y if the t
PolarNik [594]

Answer:

3x + 2y = 16

x = 2 , y = 5

Step-by-step explanation:

Given that George bought x quarts at $3.00 per quart & y quarts at $2.00 per quart and he bought 7 quarts for $16.00

Considering the total cost

3x + 2y = 16

For the cost of each

x + y = 7

solving the 2 equations simultaneously be substitution

x = 7 - y

3(7 - y) + 2y = 16

21 - 3y + 2y = 16

-3y + 2y = 16 - 21

-y = - 5

Divide both sides by -1

y = 5

x = 7 -y

x = 7 - 5

= 2

If pqrs is a square solve for x what do I do?
ICE Princess25 [194]

Answer:

x = 11

Step-by-step explanation:

Properties of a square,

1). Diagonal of a square bisect the opposite angles.

2). All interior angles of a square measure 90°.

From these properties,

m∠PQR = 90°

Since, diagonal QS bisects angle PQR,

m∠PQS = m∠RQS = 45°

(6x - 21)° = 45°

6x = 45 + 21

6x = 66

x = 11

Function or not a function.
trapecia [35]

Answer:

Not a function

Step-by-step explanation:

For 0 in the domain (input), there are two possible values in the output (range). This goes against the definition of a function, where every element in the domain must have only one value in the range.

Hope this helps!

Suppose that a1, a2, a3, . . . is an arithmetic sequence, in which a3 = 19 and a14 = 96. Find a1.
katovenus [111]
Uhhh I think you have to add 19 and 14 which shall give you the answer to a1 so it should be 33 but then I think you divide 33 and 96 or you will multiply 33 and 96
