The answer is positive because its is going in the positive column
3x+7y=-6 -7x+3y=26 -4x+4y=-32 +4x on both sides and you end up with 4y=-32+4x now divide both sides by 4 and you get y=-8+x then to incorporate that in one of the problems 3x+7(-8+x)=-6 do the distributive property with the 7 into the () and you get 3x-56+7x=-6 now add all common variables and get 10x-56=-6 now add 56 to both sides and you get 10x=50 now divide by 10 on both side and you get x=5 now for getting y to equal a number instead of an equation 3(5)+7y=-6 15+7y=-6 subtract 15 on both sides to get 7y=-21 not divide by 7 on both sides to get y=-3 your answers are y=-3 and x=5
Answer:
Fraction
Step-by-step explanation:
Fraction is a symbol that represents a part of a whole. It consists of a <em>numerator</em> and a <em>denominator. </em>The numerator is the number above the fraction bar (also known as "Vinculum), while the denominator is the number below the fraction bar. The denominator is the total number of equal parts in a whole.
Examples of Fraction:
,
and
.
In the first example,
, 1 is the numerator, while 2, is the denominator.
<u>Additional Information</u>
When the numerator is smaller than the denominator, the fraction is called <em>"proper fraction."</em> On the contrary, when the numerator is bigger than the denominator, the fraction is called <em>"improper fraction."</em>
Answer:
angles of the triangle are equal 180
so 42+82=124
180-124=56
so the answer is 56
