Answer:
infinite
Step-by-step explanation:
1/6 of 12 is 2
1/6 of 18 is 3
Plug them in
2z-3=2z-3
meaning you can put literally any number in place of z and it'd work.
Answer:
Four consecutive numbers are 2, 6, 10 and 14
Step-by-step explanation:
15(a² - 9d²) = 7(a² - d²)
15a² - 135d² = 7a² - 7d²
15a² - 7a² = 135d² - 7d²
8a² = 128d²
Putting the value of a = 8 in above we get.
8(8)² = 128d²
128d² = 512
d² = 512/128
d² = 4
d = 2
So, the four consecutive numbers are
8 - (3*2)
8 - 6 = 2
8 - 2 = 6
8 + 2 = 10
8 + (3*2)
8 + 6 = 14
Answer:
x=-20/7 or -2.857
Step-by-step explanation:
bring like terms together in each side of the = side
then work the out
Perpendicular lines will have negative reciprocal slopes
B. y = -4x+ 5 and y = 1/4x + 4
D. y = x + 4 and y = -x + 4
E. y = -3 and x = -3
I and III seem to be correct, II doesn't because, for example, if x = w = z = t = 70 and y = u = 40, then all three pairs of vertical angles in the figure have equal measure and the given condition x + y = u + w stands. But it means y is not equal to w.
