Answer:

33.75 miles in 45 minutes,

45 miles in an hour

Step-by-step explanation:

45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,

                    1 3/4= 7/4 ---> 7/4*3=5.25

car travels 5.25 miles for every 7 minutes,

45/7*5.25= 33.75 miles

1 hour (60 minutes):

using that the car travels 5.25 miles for every 7 minutes,

60/7*5.25= 45 miles

Hope that makes sense!

Z + 6 over 3 = 2z over 4
Black_prince [1.1K]
    \frac{z + 6}{3} = \frac{2z}{4}   Multiply both sides by 3
    z + 6 = \frac{(3)2z}{4}   Multiply both sides by 4
(4)z + 6 = (3)2z   Simplify
4z + 24 = 6z   Subtract 4z from both sides
        24 = 2z   Divide both sides by 2
         12 = z     Flip the sides to make it easier to read
          z = 12

Hi there!

To find this you can simply use a calculator. All you have to do is divide the numerator by the denominator to see what you get.

7/200 in decimal form is 0.035. Pretty simple.
This fraction cannot be simplified.

Hope this helps!

In a parallelogram, if the measure of y is 32 degrees what is the measure of w
alekssr [168]
Talking about a parallelogram, we know that:
opposite sides and angles are congruent
in the picture below:
∠A = ∠C
AD = BC
if one angle is right, then the rest are right as well (making it a rectangle/square)
The consecutive angles are supplementary (meaning they add up to 180)
A + D = 180°

If y and w are consecutive angles, then 
w = 180 - 32
    =148°
If they are opposite angles, w = 32° (congruent angles)
