Note that both sides were multiplied by 5.

So that would be "Multiplication Property of Equality."

Basically, this property states that if a=b, then ac = bc.

Jia rode her bike 7 7/8 miles in the morning and another 6 5/8 miles in the afternoon. How many miles did she ride altogether
loris [4]

Answer:

14 1/2

Step-by-step explanation:

Rewriting our equation with parts separated

=7 + 7/8 + 6 + 5/8

Solving the whole number parts

7 + 6=13

Solving the fraction parts

7/8 + 5/8= 12/8

Reducing the fraction part, 12/8,

12/8=3/2

Simplifying the fraction part, 3/2,

3/2=1 1/2

Combining the whole and fraction parts

13 + 1 + 12=14 1/2

Help? Multi-Step Equations - Fractions. Solve the Equation.<br>PLEASE DO IT STEP BY STEP (visual)
GREYUIT [131]
R - 10/3 + 1/2 = -11/6...if u multiply everything by the common denominator 6, it will get rid of the fractions.

(6)r - 6(10/3) + 6(1/2) = 6(-11/6)
6r - 60/3 + 6/2 = - 66/6...simplify
6r - 20 + 3 = - 11
6r - 17 = -11
6r = -11 + 17
6r = 6
r = 6/6
r = 1 <===

Is one flag a translation image of the other, or a rotation image? EXPLAIN
S_A_V [24]

The flags are a translation. Both flags are located at different origins, so it couldn't be a rotation. Both flags have the colors in the same place ( black on the bottom, white on the top) so one flag was moved up or down from the other flag, which is a translation.

Help me out please simple
const2013 [10]

<u>A straight line is 180 degrees in measure</u>

<u>The straight line is made up of three angles</u>

           --> angle 1

           --> angle 2

           --> angle with a little square on it

                     (<em>angle with a little square means it is 90 degrees in measure)</em>

<u>Let's set up an equation</u>

    angle1 + angle2 + 90 = 180\\angle1 + 87 + 90 = 180\\angle1 = 3

Thus angle 1 is <u>3 degrees</u> or the <u>second choice</u>

<u></u>

Hope that helps!
