Answer:
10x-1
Step-by-step explanation:
(4×2)=8
8+3x-8
8-8+3x=3x
(2×2)=4
4+7x-5
4-5+7x=-1+7x
3x+7x-1

The sum of the angles in the triangle always equal 180°.
Therefore:
Answer:
Let R = unit rate
R = (7/8) ÷ 1_1/4
R = (7/8) ÷ (5/4)
R = (7/8) • (4/5)
R = (7/2) • (1/5)
R = 7/10
Step-by-step explanation:
Step-by-step explanation:
radius(CE)=diameter/2=9
EF=8inch
DE=8/2=4inch
pythagorean theorem:
im right triangle,
a^2+b^2=c^2
4^2+b^2=9^2
16+b^2=81
b^2=81-16
b^2=65
b=√65
√65≈8.06
