Answer:
( 2 , 2 )
Step-by-step explanation:
Solve the eqaution :
3x +2y=10
4x-y=6
Solve the eqaution for y :
3x + 2y = 10
y = -6 + 4x
Substitute for y : 3x + 2 ( -6 + 4x ) = 10
x = 10
Substitute for the value of x : x = 2
Substitute the given value of x into the eqaution
y = -6 + 4x : y = -6 + 4 × 2
Solve the eqaution: y = -6 + 4 × 2
solve the eqaution for y : y = 2
y = 2 A possible solution : the ordered solution pair is
( 2 , 2 )
Answer:
The answer is 45 liters = $1890
Step-by-step explanation:
As 1 liter of helium = $42
So multiply 45 liters with $42
Equals $ 1890 for 45 liters of heluim
<span>Subtract 55 from 180 total degrees of a triangle to get 125.
Put 2x and x + 10 together...
3x + 10 = 125
Subtract 10 from both sides...
3x = 115
Divide by 3...
x = 38.3333
Now to find the measure of angle 2...
38.333(2) = 76.66666
Don't know if that's a multiple choice question or not, but that's what I got</span>
7. 10x-4x is y=6x, you divide 6x by 6 and y by 6.
y/6=x
The answer to this is 62.
