What is the solution to the equation <br> 13×3/4+x=7(1/4)
yan [13]
I'm going to assume you mean:

13 * (3/4) + x = 7 * (1/4)

Let's go ahead and simplify the right side.

7 * (1/4) = 1.75

So now we have:


13 * (3/4) + x = 1.75

Now let's take care of the right side. Multiplication before addition.

13 * (3/4) = 9.75

9.75 + x = 1.75

To isolate x, we subtract 9.75 from both sides.

9.75 - 9.75 + x = 1.75 - 9.75

x = -8

Hopefully I spaced this well. \('-')/

mylen [45]

Answer:

The average speed is:

\var{v}=75\: miles/h

Step-by-step explanation:

The average speed equation is given by:

\var{v}=\frac{\Delta x}{\Delta t}

Were:

  • Δx is the displacement (225 miles)
  • Δt is the change in time (3 hours)

Then we have:

\var{v}=\frac{225}{3}

\var{v}=75\: miles/h

I hope it helps you!

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
