a parallel line has the same gradient, so the gradient would be 3 1/3
a perpendicular line has the negative inverse gradient of the original (eg. if the original gradient is 4/3 then the perpendicular gradient would be -3/4 (all you have to do is change the +/- sign and flip the fraction), so in your case the gradient of the perpendicular line would be -3/10 (since 3 1/3 = 10/3)
The measure of a straight line is 180
125+30=155
180-155=25
x = 25
The picture looks confusing.
You divide 10000 by 1/10 then times that by 2 which equals 200,000 then divide that by 1/8 which is 160,000 then by 1/2 and you get 3,200,000
Your pay rate is $4.50/hour.
27/6=4.5=$4.50
Answer:
C
Step-by-step explanation:
6(a+b) + 2z = -8 ; divide by 2
3(a+b) + z = -4
a+b+z = 2; subtract z from both sides
a+b = 2-z; substitute a+b into equation 3(a+b) +z = -4
3(2-z) +z = -4; distribute
6 - 3z+ z= -4 ; subtract 6 on both sides
-3z + z = -4 -6 ; combine like terms
-2z = -10; divide both sides by -2
z= 5
3(a+b) +z = -4; substitute z by 5
3(a+b) +5 = -4; subtract 5 from both sides
3( a+b) = -4 -5; combine like terms
3(a+b) = -9; divide both sides by 3
(a+b) = -3
