<span>We know that OB bisects EC where they intersect would be at point O, 
so the two lengths EO and OC must be equal. 

2x - 20 = 70 - x 

</span>[adding x + 20 to each side] 

2x - 20 + x + 20 = 70 - x + x + 20

[simplifying]

<span>3x = 90 

</span>[dividing each side by 3]
<span>
x = 30 would be the answer</span>

When 1 is subtracted from three- tenths of the number, the result is equal to one-fifth of a number. What is the number
Bas_tet [7]
Based on the given mathematical statement, it can be rewritten into a mathematical equation to simplify and to be solved easily. The statement, "When one is subtracted from three-tenths of a number" corresponds to the equation, 3x/10 - 1, that is assuming the number is represented by the variable x. This is equal to one-fifth of the number. In other words,
3x/10 - 1 = x/5
x = 10

What is the value of h?
storchak [24]

Answer:

\large\boxed{h=5.488\ in}

Step-by-step explanation:

The formula of an area of a parallelogram:

A=bh

b - base

h - height

We have:

base₁ = 9.8 in

base₂ = 10 in

height₁ = 5.6 in

height₂ = h

The area of a parallelogram:

A=b_1h_1 and A=b_2h_2

Therefore we have the equation:

b_2h_2=b_1h_1

Substitute:

10h=(9.8)(5.6)

10h=54.88          <em>divide both sides by 10</em>

h=5.488\ in
