How do I solve 4x + 3y=0 & 2x + y = -2 using substitution

Answers

4x + 3y = 0
2x + y = -2
take 2x and subtract to the side with -2
it'll look like this: y = -2x - 2
plug that equation in where the y is in the other equation.
it'll look like this: 4x + 3(-2x - 2)=0
which you multiply 3 and the -2x and the -2
which the equation would be: 4x - 6x - 6=0
put together like terms: -2x - 6=0
add the 6 to the side with the zero: -2x = 6
divide both sides by -2 which x= -3
to get y you plug in the answer for x (-3)
2(-3)+y= -2
so it'd then be -6 + y = -2
add the -6 to the side with -2
y= -2 +6
y= 4
so your complete answer is ( -3, 4)

if 3 is added to a number and the sum is tripled, the result is 19 more than the number. find the number

Answers

Answer:

The number is 5

Step-by-step explanation:

if 3 is added to a number and the sum is tripled, the result is 19 more than the number

(n+3) *3 = n+19

Distribute the 3

3n +9 = n+19

Subtract n from each side

3n-n +9 = n-n+19

2n +9 = 19

Subtract 9 from each side

2n+9-9 = 19-9

2n =10

Divide by 2

2n/2 =10/2

n=5

The number is 5

Answer:

(x + 3)·3 = x + 19 --> x = 5

A scientist estimated that a mixture would need 3 milliliters of a chemical to balance. The actual amount needed was 7 milliliters. What was the percent error of the scientist's estimation?A. 133.33%
B. 3%
C. 42.86%
D. 57.14%

Answers

Answer:

57.14%

Step-by-step explanation:

Error(E)is defined as the percentage difference an estimate(e) amount is from the actual(a) amount. The actual amount need was 7 mililters and the estimate was 3 mililiters.

Error is defined as:

$E=(a-e/a)*100$

$E=(7-3/7)*100=57.14$

The percet error if the scientists estimation is 57.14%

I need help with estimating, then finding the quotient and write the remainder if any as a fraction?

Answers

When estimating, you want to round the dividend and the divisor to the nearest time table number (i.e. 5700 --> 5400). Finding the quotient is easier when you estimate. Writing the remainder as a fraction is simple. First, get your remainder and your divisor, then make it to a fraction.

ex:

If you get a remainder of 3, and have a divisor if 12, your remainder would be 3/12, or 1/4.
