Step-by-step explanation:
-12 + 11 = -1
-1 + 11 = 10
10 + 11 = 21
21 + 11 = 32
32 + 11 = 43
Answer:
<h2>Question 13 : x = 62°</h2>
<h2>Question 14 : x = 2</h2>
Step-by-step explanation:
Question 13
The diagram in question 13 is a triangle.
The sum of interior angles of a triangle is equal to 180°
To solve for x ;

Question 14
(: represents ratio or /)
x/9 = 18/81
Cross Multiply
81x = 18×9
81x = 162
Divide both sides of the equation by 81
81x/81 = 162/81
x = 2
Answer:
20:£1
Step-by-step explanation:
To simplify a ratio is like like simplifying a fraction
Take 4/8 as an example. Find a number you can divide both numbers with. In this case, it's 4. 4 divided by 4= 1, and 8 divided by 4= 2. So, the simplified version of 4/8 is 1/2. Similarly, with the ration 60:£3, you find the number you can divided both numbers with. In this case, it is 3. 3 divided by 3= 1, and 60 divided by 3= 20.
Final Answer: 20:£1
First number is (n)
second number is (n - 4) --- first number diminished by 4
third number is (4n) --- 4 times the first number
I pretty sure it’s B because you have to undo what is being done to 4/5 which would be to divid it on both sides then all you have left is x + 20 so you should subtract it to get x by itself.
