Answer:
<h3> ∠R = 69</h3>
Step-by-step explanation:
<h2>Angle sum property</h2>
Sum of all angles of triangle = 180
5x - 11 + 3x - 3 + 3x + 18 = 180
5x + 3x + 3x -11 - 3 + 18 = 180
Combine like terms
11x + 4 = 180
11x = 180 - 4
11x = 176
x = 176/11
x = 16
∠R = 5x - 11
= 5*16 - 11
= 80 - 11
= 69
Answer:
21/25 = 84/100
17/20 = 85/100
21/25 < 17/20
Step-by-step explanation:
∵ The common multiple of 25 and 20 is 100
∵ 100 ÷ 25 = 4
∴ 21/25 = (21 × 4)/(25 × 4) = 84/100
∵ 100 ÷ 20 = 5
∴ 17/20 = (17 × 5)/(20 × 5) = 85/100
∵ 84 < 85
∴ 84/100 < 85/100
∴ 21/25 < 17/20
Answer:
3(9m + 13) - (m + 10) = 1
Step-by-step explanation:
Here, we want to write an equation we can use to find the age of Mario.
Let the present age of Mario be M
Age of Sarah is 3 years older than 9
times Mario’s age
Mario’s age is thus;
9m + 3
In ten years, she will be 1 less than triple his age
In 10 years time, sarah age will be 9m +
3 + 10 = 9m + 13
Mario age will be m + 10
Mathematically;
3(9m + 13) - (m + 10) = 1
