These both equations are parallel so they can't be solved
5x + 2y = 7
10x + 4y = 14

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

What is the simple Intrest to 1,250 at 4.5% for 2 years
Anettt [7]

Answer:

1,362.50 Dollars

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.5%/100 = 0.045 per year.

Solving our equation:

A = 1250(1 + (0.045 × 2)) = 1362.5

A = $1,362.50

Then You Get 1362.50 Dollars

How to multiply whole numbers by fractions​
Setler79 [48]

Answer:

Any whole number is over one...so if the whole number was 5 it would be \frac{5}{1} bkuz the line in between the numerator and denominator is a dividing sign and 5 divided by 1 is 5

So you put the whole number whatever it is over 1 then multiply that by the fraction

Example:

6 x \frac{3}{4} is the same as saying \frac{6}{1} x \frac{3}{4} which equals \frac{18}{4} because 6 times 3 equals 18 and 4 times 1 equals 4

Now you need to simplify or divide...

So, \frac{18}{4} is the same as 4 \frac{2}{4} or 4\frac{1}{2} bkuz 4 goes into 18 4 and a half times
