Just multiply the number out of the parentheses with the ones inside. So -8 times 9=-72 and 3q times -8=-24q. Now keep the same operation, which is subtraction in this case.So, -72--24q or -72+24q will be the correct answer.
Answer:
a) <u><em>The watch is cheaper in Geneva.</em></u>
b) <u><em>The watch is cheaper by £20</em></u>
Step-by-step explanation:
a) In which city is the watch cheaper?
Step 1. Translate Pounds into Swiss Francs.
£145 * 1.55 = 224.75 CHF
Step 2. Determine which price is higher.
224.75 is greater than 193.75.
Step 3. Always answer a Word problem in complete sentences.
<u><em>The watch is cheaper in Geneva. </em></u>
b) By how much is it cheaper?
224.75 - 193.75 = 31
Translate CHF to Pounds.
31 / 1.55 = 20
<u><em>The watch is cheaper by £20.</em></u>
5x + 2y = 12
-6x - 2y = -14
Add them
-x = -2
x = 2
5x + 2y = 12
(5*2) + 2y = 12
10 + 2y = 12
2y = 2
y = 1
Answer:
The missing angle 'x' is 22.29°.
i.e. 
Step-by-step explanation:
Let 'x' be the missing angle of the triangle.
Using the formula
tan x = opp ÷ adjacent
tan x = 30 ÷ 72
tan x = 0.41
Therefore, the missing angle 'x' is 22.29°.
