Hello,

Answer B

y=-3x-2 ==>3x+y=-2 (1)
5x+2y=15  (2)

(2)+2*(1)==>-x=19 ==> x=-19
y=-3*(-19)-2 ==>y=55
Sol={(-19,55)}

Reorganize the equations;
y+ 3x   =-2
2y+5x=15
-----------
Multiply equation I by two for y to have a common factor;
2y+6x=-4
2y+5x=15
--------------
x=-19
Replacing value of y in equation 1;
y+(3*-19)=-2
y-57=-2
y=55

5/6+2/9= in simplest form I NEED this plz help
tensa zangetsu [6.8K]

Answer: 1  1/18

Step-by-step explanation: 5/6 + 2/9 I know this might seem like common, but <em>the </em><em>Numerator is the top number of a fraction</em><em> and the </em><em>Denominator is the bottom a fraction.</em> When the numerator and the denominator are the same such as 5/5 the fraction equals one (I know its real fancy). When you're multiplying a fraction that equals on by another fraction its really just multiplying by a fancy looking 1 that's disguised as a fraction such as  5/5. If you simplify it it goes to the fraction it was as long it was simplified to the max  (5/5 x 1/2 = 5/10= 1/2)

  • First, you need to find a like denominator,  which is 18
  • Then, you got to multiply each fraction to make them have common denominators ...multiply 5/6 by 3/3  ( 3/3 is just  a fancy way of saying one) 5/6 x 3/3 = 15/18....multiply  2/9 by 2/2 (which is just another fancy way of saying one ) 2/9 x 2/2=4/18
  • Next you add them but only the numerator  15/18 + 4/18 = 19/18
  • Finally, you change the the fraction into a mixed number 1 and 1/18

A single one of them is called a "vertex". It's a point where edges meet.
A triangle has 3 of them.
A square has 4 of them.
A cube or a brick has 8 of them.
Can you look around and find the 8 vertices of your bedroom ?
