What's the value of x and y when 4x+y=210 and 3x+2y=195?

Answers

Answer 1

Answer: after substitution method, I got x=45 and y=30

Answer 2

Answer: You already hve the answer, but you do this by turning the equation into standard form. Since we are isolating y for each linear equation, we must first subtract the 4x and 3x on both sides. This should come out to y=-4x+219 and 2y=-3x+195. Since we have our first equation in standard form, all we have go do is divide 2 on both sides frome the second equation. Then you can solve by substitution (y=y)

The division $(5)/(4623)$ results in the simple decimal 0.001081603. This expression is already reduced to the most basic fraction form of itself.

The division is an arithmetic operation that involves splitting a quantity or number into equal parts or groups. It is the inverse operation of multiplication. In division, a number called the dividend is divided by another number called the divisor to obtain the quotient.

The dividend is the total quantity or number being divided, while the divisor is the number by which the dividend is divided. The result of the division is called the quotient, which represents the number of times the divisor can be subtracted from the dividend to achieve equal parts.

Given the expression $(5)/(4623)$ ,

$(5)/(4623)$ = 5 $/$ 4623 = 0.001081603.

9 POINTS! Please help!

Answers

2x + 8y = 17
10x + 3y = 11

We need to solve the system of equations.

x = pencils
y = notebooks

If we solve by graphing, we get the answer:

One pencil costs 0.50 dollars
One notebook costs 2.00 dollars

Which statement explains why –27 is the opposite number of 27? Answer Choices They are the same quantity with different signs. They are an equal distance from 1 on the number line. They are both greater than 0. They are odd numbers.

Answers

Now... -27 and 27 are equally the same number, but in different signs, but they are also same distance from each other. So i'd say: They are the same quantity with different signs.

"They are the same quantity with different signs" is the answer, 27 and -27 are the same number ( quantity) just one is a positive number and the other is a negative number.
