Classify the triangle by its sides and angles

Montano1993 [528]

This is an acute scalene triangle

The triangle is acute since all three angles (58, 57, 65) are less than 90 degrees

The triangle is scalene as the angles are all different. So this leads to the sides being different lengths. No two sides are the same length.

What is the solution to 3x -2y =1 and 4y = 7 + 3x

Delvig [45]

Given.

$3x-2y=1$ (1)

$4y=7+3x$ (2)

Re-arrange equation (2)

$(4y=7+3x)-4y$

$0=-4y+3x+7$

$(0=-4y+3x+7)-7$

$-7=-4y+3x$

Multiply equation (2) by -1

$-1(3x-4y=-7)$

$-3x+4y=7$ (3)

Combine like terms and solve.

$3x-3x-2y+4y=1+7$

$2y=8$

Divide by (2y) and solve for (y).

$\frac{2y}{2}=\frac{8}{2}$

$y=4$

Substitute (y) for equation (1).

$3x-2y=1$

$3x-2(4)=1$

$3x-8=1$

Add (8) to both sides.

$(3x-8)+8=(1)+8$

$3x=9$

Divide by (3).

$\frac{3x}{3}=\frac{9}{3}$

$x=3$

Check your work.

$3x-2y=1$

$3(3)-2(4)=1$

$9-8=1$

$1=1$

$4y=7+3x$

$4(4)=7+3(3)$

$16=7+9$

$16=16$

Your answers is $x=3$ and $y=4$
