Answer:
x = -4
, y = -6
Step-by-step explanation:
Solve the following system:
{y = -5 x - 26 | (equation 1)
5 y = 3 x - 18 | (equation 2)
Express the system in standard form:
{5 x + y = -26 | (equation 1)
-(3 x) + 5 y = -18 | (equation 2)
Add 3/5 × (equation 1) to equation 2:
{5 x + y = -26 | (equation 1)
0 x+(28 y)/5 = (-168)/5 | (equation 2)
Multiply equation 2 by 5/28:
{5 x + y = -26 | (equation 1)
0 x+y = -6 | (equation 2)
Subtract equation 2 from equation 1:
{5 x+0 y = -20 | (equation 1)
0 x+y = -6 | (equation 2)
Divide equation 1 by 5:
{x+0 y = -4 | (equation 1)
0 x+y = -6 | (equation 2)
Collect results:
Answer: {x = -4
, y = -6
I'm pretty sure both B and C equal 12 as well
Since the triangle equals 180 and the angels are all congruent
Answer 1: Meal
Answer 2: Spinning the number less than 3 and fliping tailes
Step-by-step explanation 1: Because there are way more choices to choose from so more people will go for the meal chose.
Step-by-step explanation 2: It is more likely to land on a 3 or below because of the chances and for it to land on heads is a 50-50 chance
Hope this helped!
A fraction actually represents a division problem that can return a decimal real number with which you can solve some problems. ie:4/3 = 4÷3 = 1.333
a. 6×1.25=x 6×1.333=x 6×1.5=x 6×1.75=x 6×2=x make sense?
b. 6×.666=x
c. by definition a cube has equal length sides in all 3 dimensions.
