1. 11x + 7x = 8x
2. 15y - 20y = -5y
Answer:
base angles each measure 68 degrees
third angle measures 34 degrees
Step-by-step explanation:
let '2x' = measure of each base angle
let 'x' = measure of third angle
the sum of all three must equal 180 degrees so you can write this equation:
2x + 2x + x = 180
combine 'like terms' to get:
5x = 180
divide each side by 5 to get:
x = 34
therefore, twice 'x' is 68
check:
68 + 68 + 34 = 180
180 = 180
Answer:
The answer to your question is Russia is 50 times greater than Finland.
Step-by-step explanation:
Data
Finland area = 3.4 x 10⁵ km²
Russia area = 1.7 x 10⁷ km²
Proportion = ?
Process
1.- Just divide the Russia's area by the Finland's area.
Proportion = 
Proportion = 
Porportion = 50
Answer:
area - 6 x 2 = 12
area lateral surface - 7 x 6 = 42
