Answer:

The answer is A and C

Step-by-step explanation:

The answer is A because 12.3 multiplied by 10 is 123, and 0.4 multiplied by 10 is 4.

12.3 * 10 = 123

0.4 * 10 = 4

So, this shows that this equation is the same as 12.3 divided by 0.4

The answer is C because 12.3 multiplied by 100 is equal to 1230, this is the same for 0.4

12.3 * 100 = 1230

0.4 * 100 = 40

So, the answer is both A and C.

Hope this helps! :)

Answer:

12.3 divided by 0.4 is 30.75

Step-by-step explanation:

<em>You then go to letter A and 123/4 is also 30.75</em>

<em>but you go through the rest of the choices just in case. </em>

<em>B is 3.075 so that is incorrect </em>

<em>C is 307.5 so that is also incorrect </em>

<em>D is 3075 and that is incorrect and not 30.75.</em>

Therefore your answer is A.

30.75 = 30.75.

Hope this helps :)

Find the value of x and y that satisfy both the equalities x/y=2/3 and y/24=3/4<br> .
egoroff_w [7]

x=12 and y=18 satisfies both the equalities.

Step-by-step explanation:

Given equations are;

x/y = 2/3   Eqn 1

y/24 = 3/4   Eqn 2

Multplying by 24 on both sides of Eqn 2

24*\frac{y}{24}=\frac{3}{4}*24\\\frac{24y}{24}=\frac{72}{4}\\y=18

Putting y=18 in Eqn 1;

\frac{x}{18}=\frac{2}{3}

Multiplying both sides by 18

18*\frac{x}{18}=\frac{2}{3}*18\\\frac{18x}{18}=\frac{36}{3}\\x=12

Putting both values in Eqn 1

\frac{12}{18}=\frac{2}{3}\\

As 12 and 18 are multiples of 6;

\frac{2}{3}=\frac{2}{3}

x=12 and y=18 satisfies both the equalities.

line segment AB has endpoints A (5,-3) and -(7,-5). what are the coordinates of the midpoint of segment AB
loris [4]

Answer:

see below

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates together and divide by 2

(5+7)/2 = 12/2 =6

If that was supposed to be -7

(5-7)/2 = -2/2 =-1

To find the y coordinate of the midpoint, add the y coordinates together and divide by 2

(-3+-5)/2 = -8/2 =-4

Either (6,-4) if +7  or (-1,-4) if -7
