Answer:
52
Step-by-step explanation:
complementary angles meaning sum of both angles is 90
so equations is
(4x + 3) + (15x – 8) = 90
x=5
insert x into angle d equation
d=15(5)-8
d=60-8
d=52
Answer:
A. Basalt plateau
Step-by-step explanation:
Basalt plateau is an extensive, thick, smooth flow or succession of flows of high-temperature. This forms like a plateau.
3 1/3= 10/3
1 7/10= 17/10
Common denominator is 30.
So 10/3= 100/30
And 17/10= 51/30
(100/30)-(51/30)= 49/30
49/30= 1 19/30
Answer:
Yes.
Step-by-step explanation:
Just like normal algebra, you factor our the common factor, in this case, 5.
Thus,
