3y + 1 - 2y = -3 - 3y

Mathematics
2 answers:
Arada [10]3 years ago

Answer:

y=-1

Step-by-step explanation:

First you combine like terms.

1y+1=-3-3y

Then you add 3 on both sides so the -3 cancels out.

1y+4=-3y

Then you subtract 1y on both sides to cancel out y.

4=-4y

Then you divide both sides by -4 to get y by itself.

y=-1

An equilateral triangle has has an era of 43.5 square feet the height is 8.5 feet what is the Perimeter of the triangle
enot [183]

Answer:

30.7 ft

Step-by-step explanation:

<em>An equilateral triangle with area 43.5 has a height of 8.68 not 8.5</em>

<em>I will do the problem as written even though it is not a possible equilateral triangle</em>

<em>---------------------------------------------</em>

a = (1/2)bh

43.5 = (1/2)b(8.5)

43.5 = 4.25b

b = 43.5/4.25

b = 10.2352941176

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

p = 3b

p = 3 * 10.2352941176

p = 30.7058823528

~ 30.7 ft

Solve the system of equations. x+2y=6; 3x-14y=8 please help
ira [324]
Let x = 6 = 2y so
3(6 - 2y) + 14y = 8 so
18 - 6y + 14y = 8 so
8y = -10 and
y =  \frac{ - 10}{8} =   - \frac{5}{4}  \\  \\ since \: x = 6 - 2y \\ 6  - 2( \frac{ - 5}{4}) = x  \: so \\ x = 6 +  \frac{10}{4} =  \frac{24}{4} +  \frac{10}{4} =  \frac{34}{4} =  \frac{17}{2}
