The general form for a pair of linear equations in two variables x and y is
and
----- (1)
----- (2)
Comparing equations 1 and 2 with the general form of equation to write their co-efficient,
Compare the ratio,
If , then the pair of linear equations has exactly one solution.
So, it said to be consistent.
Answer:
(6 - √ 100 - 6 * 6) 3 - 9 ÷ 3 = -64003/1 = -64003
Step-by-step explanation:
1.Square root: sqrt(100) = √ 100 = 10
2.Subtract: 6 - the result of step No. 1 = 6 - 10 = -4
3.Multiple: 6 * 6 = 36
4.Subtract: the result of step No. 2 - the result of step No. 3 = -4 - 36 = -40
5.Exponentiation: the result of step No. 4 ^ 3 = (-40) ^ 3 = -64000
6.Divide: 9 / 3 = 3
7.Subtract: the result of step No. 5 - the result of step No. 6 = -64000 - 3 = -64003
3(x+4)= 3x+12
3x+12+x+3+x=5x + 15
5x+15=180
5x=180-15
5x=165
x=165/5
x= 33min
mowing the grass = 3(x+4)
= 3(33+4)
=99+12
=111 min mowing grass
Answer:
10.85
Step-by-step explanation:
Opposite angles in a parallelogram are congruent, so 3x+40 = x+50 and x = 5. That means that those 2 angles measure 3(5)+40 = 55, and the other 2 angles, which are congruent to each other, add up with the other to equal 360. 360-55-55=250. Divide that between the other 2 remaining angles to get that those angles each measure 125.
