Answer: the answer is 3/10


Step-by-step explanation: take 30% and convert it into a decimal and find what decimal place the three is in the thake the three and put it over the decimal place name for instance (if i have 50% i would turn it into the decimal 0.5 then see if the five is in the tenths place or the hundrenths place on the decimal and i see that the 5 is in the tenths place so my ratio for the 50% would be 5/10 because .5 is basicly 5/10 i'm just converting the percentag to a decimal then to a fraction

How substation y=3x-7 <br> 2y+4x=36
SSSSS [86.1K]

The solution is:

x = 5

y = 8

Step-by-step explanation:

Given equations are:

y=3x-7\ \ \ Eqn\ 1\\2y+4y = 36\ \ \ Eqn\ 2

Putting y = 3x-7 in equation 2

2(3x-7)+4x = 36\\6x-14+4x = 36\\10x-14 = 36\\10x = 36+14\\10x = 50

Dividing both sides by 10

\frac{10x}{10} = \frac{50}{10}\\x = 5

Putting x=5 in eqn 1

y = 3(5)-7\\= 15-7 = 8

Hence,

x = 5

y = 8

Solve the solution. How many solutions does it have? 4(2x-3)=2(4x-6)
sdas [7]

Answer:

No solutions

Step-by-step explanation:

4(2x-3)=2(4x-6)

4(2x-3)=2 \times 2(2x-3) \\  \\ 4(2x-3)=4(2x-3)

Same components are present on both sides of equal sign, therefore NO SOLUTIONS are possible.
