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

Work from the inside out
Change subtracting negatives to adding
(−4)+2–{(−5)–[(−7)+(−3)+8)]}
(−4)+2–{(−5)–[(-2)]}
(−4)+2–{-5+2}
(−4)+2–(−3)
Changing to adding
(−4)+2+3
-2+3

They are vertical angles and would be the same so set them to equal each other and solve:
3x-4 = 2x+9
add 4 to both sides:
3x = 2x +13
subtract 2x from each side:
x = 13
now replace x with 13 in the original equations:
3x-4 = 3(13) -4 = 39-4 = 35
2x+9 = 2(13)+9 = 26+9 = 35
the angles = 35 degrees
Answer:
46656
Step-by-step explanation:
6x6x6x6x6x6x6 can be written in its index form as 6⁷
6x = 6⁷
6x = 279936
Applying change of subject formula, divide both sides of the equation by 6
6x/6 = 279936/6
x = 46656
The answer is 13/20
The number (n) halfway between x and y is:
n = (x + y) : 2
The number (n) halfway between 3/5 and 7/10 is:
n = (3/5 + 7/10) : 2
n = (6/10 + 7/10) : 2
n = 13/10 : 2
n = 13/10 : 2/1
n = 13/10 * 1/2
n = 13/20
Answer:
$67.25
Step-by-step explanation:
52.60 x 8% = 52.60 x 0.08 = 4.21
52.60 x 20% = 52.60 x 0.20 = 10.44
52.60 + 4.21 + 10.44 = 67.25
