Answer:
1
Step-by-step explanation:
(−4)−(−2)–{(−5)–[(−7)+(−3)–(−8)]}
-4 + 2 - {-5 - [-7 - 3 + 8]}
-2 - [-5 + 7 + 3 - 8]
-2 - (-3)
-2 + 3

Answer:
A- 15
Step-by-step explanation:
I think option no a is answer
Step-by-step explanation:
c) since m = undefined => the equation is
x = -2
d) the equation is
y-2= -1/7 (x+7)
=> y = -1/7 x -1+2
<=> y = -1/7 x + 1
Of course, this statement is FALSE.
Let`s assume that a small town in Nevada had a population of 1,000.
When it lost 20% of its population:
1,000 * ( 1 - 0.2 ) = 1,000 - 0.8 = 800
After that the same town gained 20 % more people:
800 * ( 1 + 0.2 ) = 800 * 1.2 = 960
960 ≠ 1,000
In the end the town`s population was not the same as it was before the downturm.
Answer:
8/15 x 5/8 = 1/3
2/9 x 3/4 = 1/2
Step-by-step explanation:
multiply the numerators and denominators together.
8/15 x 5/8 = (8 x 5)/ (15 x 8)
40/120
Simplify by dividing by 40. (GCF)
1/3
----------------------------------------------------------------------------------------------------
multiply the numerators and denominators together.
2/9 x 3/4 = (2 x 3)/ (9 x 4)
6/36
Simplify by dividing by 6. (GCF)
1/2
