Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180
Multiplying by 1 keeps it the same. A number greater than 1 would be an increase and a number below 1 would be a decrease.
The decrease is 2.7% which is written as 0.027 as a decimal.
Subtract that from 1:
1 - 0.027 = 0.973
The multiplier would be 0.973
Answer:
G(-3) = -12, and F(-3) = -10.
Step-by-step explanation:
G(n) = 3n - 3
G(-3) = 3(-3) - 3, which is equivalent to -9 - 3, or -12.
F(n) = 2n - 4
F(-3) = 2(-3) - 4, which is equivalent to -6 - 4, or -10.
The answer is 7x/12 - 1/2. Its the first option in your picture. Hope this helps .
