Answer:
x=4
Step-by-step explanation:
y=2x-10 and 6x+7y=10
6x+7(2x-10)=10
6x+14x-70=10
20x=80
x=4
x = 2
Collect terms in x to one side of the equation and numeric values on the other side.
1 + 4x = - 5 + 7x ( subtract 7x from both sides )
1 + 4x - 7x = - 5
1 - 3x = - 5 ( subtract 1 from both sides )
- 3x = - 6 ( divide both sides by - 3 )
x = 
= 2

Answer:
175.1
Step-by-step explanation:
Find the area of the semicircle:
(pi • radius²) / 2. [Radius is half of diameter]
(3.14 • 4²) / 2
(3.14 • 16) / 2
(50.24) / 2
25.12
Find the area of the parallelogram:
(base • height)
(30 • 5)
150
Add the areas of both shapes to get total area
25.12 + 150 = 175.12, round to the nearest tenths, 175.1
Hope this helps!
