Answer:
Step-by-step explanation:
To find a positive and a negative angle coterminal with a given angle, you can add and subtract 360°.
-135° + 360° = 225°
Answer: 27 and 9
Step-by-step explanation:
Coefficients are the numbers in front of variables. Since the variables are x and y, then the coefficients are 27 and 9.
Answer:
$12,709
Step-by-step explanation:
P = $10,000
r = 3% = 0.03
t = 8 Years
n = Compounded Monthly = 12
A = P [1 + (r / n)]^nt
A = $10,000 [1 + (0.03 / 12)]¹² ˣ ⁸
A = $10,000 [1 + 0.0025]⁹⁶
A = $10,000 [1.0025]⁹⁶
A = $10,000 x 1.270868
A = $12,709
1. Let the shorter piece be x in. long
the longer piece will be x + 13 in. long
and the two pieces add up to be 47 in., so
x + ( x + 13 ) = 47
2x = 47 - 13
2x = 34
x = 17
the longer piece is x + 13 in. long,, or 17 + 13 = 30 in. long
2. number of dimes: x
number of quarters: y
x + y = 27....(1)
10x + 25y = 405...(2)
(1)*10: 10x + 10y = 270....(3)
(2) - (3):15y = 135
y = 9
plug y = 9 into (1), you will find that x = 18
so 18 dimes, 9 quarters
Answer:
it would be 5 because there's 4 x's on 2 and there's 1 on 0
