Answer:
angle 1 should equal to 54.
angle 2 should equal to 126.
Step-by-step explanation:
2x - 8 + 4x + 2 = 180
2x + 4x - 8 + 2 = 180
6x - 6 = 180
6x - 6 + 6 = 180 + 6
6x = 186
6x ÷ 6 = 186 ÷ 6
x = 31
---------------------------------------------
2x - 8 = A1
2(31) - 8 = A1
62 - 8 = A1
54 = A1
-----------------------------------------------
4x + 2 = A2
4(31) + 2 = A2
124 + 2 = A2
126 = A2
Answer:
each number is the answer
Step-by-step explanation:
H (x) = 5 x 2^-x
2^-x is the same as saying 1/2^x .
h (x) = 5 x 1/2^x
h (3) = 5 x 1/2^3
= 5 x 1/8
= 5/8
Therefore h (3) = 5/8

Answer:
quantity of red paint = 12.5 gallons
quantity of blue paint = 7.5 gallons
Step-by-step explanation:
Ratio of red and blue paint : 5:3
in ratio
a:b = ax:bx
let the
quantity of red paint be 5x
quantity of blue paint be 3x
then quantity of purple paint = quantity of red paint + quantity of blue paint
= 8x
given quantity of purple paint is 20 gallons
thus,
8x = 20
x = 20/8 = 2.5
thus,
quantity of red paint = 5x = 5*2.5 = 12.5 gallons
quantity of blue paint = 3x = 3x*2.5 = 7.5 gallons
