3x - 12 = 12

+ 12 + 12

_________

3x = 24

5/6 – 6/12<br><br>I am lost bc I'm not a math person so pls help me?
vovangra [49]

First, we must find the common denominator (12)            ✵

10/12-6/12            ✵                 ✵                              ✵                              ✵

Now, why 10?                                     ✵                   ✵                      ✵

Because we CAN'T just take the denominator and change it; we must change both the denominator AND the numerator:

✵                                      •          -                                      ○          

4/12                  ✧                             ✩                                  ✶            ✺         ✱  

We can simplify, or reduce, this fraction:                  ✱  ✱

1/3              ✩                              ✦                                        ✤

I hope it helps!

Can someone please help me on solving: x+y=-4
timama [110]

Answer: x=-1 and y= -3

Step-by-step explanation:

Solve for x, x+y=-4

Minus y from both sides so it'll be X=-y-4

Now substitute -y-4 in x-y=2 and solve for y

-y - 4 -y=2

Add like terms, -2y - 4=2

Add 4 to both sides -2y=6

Divide both sides by -2 \frac{-2y}{-2} = \frac{6}{-2}

y= -3

Substitute -3 in x=-y - 4

x=-(-3) - 4

- × (-3)= 3

3 - 4= -1

x= -1

Edgar owns 234 shares of Cawh Consolidated Bank, which he bought for $21.38 apiece. Each share pays a yearly dividend of $3.15.
trapecia [35]

Answer: B. The stocks have a yield 6.84 percentage points greater than that of the bonds.

Step-by-step explanation:

Firstly, the yield for stocks will be calculated as:

= return/ investment cost

= $3.15/$ 21.38

= 0.14733395

= 14.73%

The yield for bonds will be calculated as:

= Return/Investment cost

Return = 1,000 x 8.3% = 83

Investment cost = 1,000 x 105.166/100 = 1051.66‬

Yield = 83/1051.66

= 0.07892284

= 7.89%

Then, the difference between the yield will be:

= 14.73% - 7.89%

= 6.84%

Therefore, the stocks have a yield 6.84 percentage points greater than that of the bonds.
