Answer:
R32.15
Step-by-step explanation:
Let x and y represent the original price of a loaf of bread and a liter of drink, respectively. The two relations given by the problem statement are ...
10x +12y = 138.90
10(1.2x) +12(1.1y) = 159.54
Multiplying the first equation by 1.2 and subtracting the second gives ...
1.2(10x +12y) -(10(1.2x) +12(1.1y)) = 1.2(138.90) -(159.54)
1.2y = 7.14 . . . . collect terms
y = 5.95 . . . . . divide by 1.2
The value of x can be found from the first equation.
10x + 12(5.95) = 138.90
10x = 67.50 . . . . . . . . . . . subtract 71.40
x = 6.75 . . . . divide by 10
Then the value of 3x+2y is ...
3(6.75) +2(5.95) = 32.15
The original price of 3 loaves and 2 liters is R31.15.
Answer: D
Step-by-step explanation:
0.34 = 34/100
34/100 = 17/50
Answer:
27°
Step-by-step explanation:
we have the 'opposite' as length 2 is opposite the angle θ
we have the adjacent (length 4) which is next to the angle θ
the hypotenuse is the longest side (we don't need)
Using SOHCAHTOA
we use TOA as O is opposite and A is adjacent
tanθ = opposite ÷ adjacent
tanθ = 2 ÷ 4
using the inverse sign to find θ
θ = tan⁻¹(2/4) = 27° (to the nearest whole degree)
