Answer:6.27
Step-by-step explanation: 22.8 increased by 27.5%
27.5% × 22.8 = 6.27
27.5 ÷ 100 × 22.8 = 6.27
27.5 × 22.8 ÷ 100 = 6.27
627 ÷ 100 = 6.27
An algebraic expression is, obviously, an expression with a variable.
"A number" would represent a variable, which, in this case, we'll use y.
So, 15 decreased by twice x.
15 - y x 2 =
I hope this helped :)
Answer:
Step-by-step explanation:
From the data given,
∠MON=8x−13
∠LOM=7x−17
∠LON= is a straight line angle, i.e. it is 180°
Then, the sum of MON and LOM is equal to LON
∠MON + ∠LOM = ∠LON
8x-13 + 7x - 17 = 180
15x -30 = 180
15x = 180+30
15x =210
x =210/15
x = 14°
We want to find MON
∠MON=8x−13
∠MON=8(14)−13
∠MON=112−13
∠MON= 99°
