4-2x=11 how do I solve

Mathematics

Bingel [31]3 years ago

Hey there!☺

Answer:\boxed{x=\frac{-7}{2}}

Explanation:

4-2x=11

In our first step, we will simplify both sides of the equation:

4+-2x=11\\-2x+4=11

Now subtract 4 from both sides:

-2x+4-4=11-4\\-2x=7

In our last step, we will divide both sides by -2:

\frac{-2x}{2}=\frac{7}{-2}\\  x=\frac{-7}{2}

x=-7/2 is your answer.

Hope this helps!☺

29 mint plants and 29 other herb plants at the garden center. Considering this data, how many of the next 62 herb plants stocked
spin [16.1K]

Answer: 31 mint plants

Step-by-step explanation:

         We will have mint plants over total plants:

29/29+29 = 29/58 = 1/2

         Now, we will multiply 62 by 1/2 to guess how many mint plants will be stocked.

62* 1/2 = 31

  We should expect about 31 plants of the total plants to be mint plants.

A collection of dimes and quarters is worth $10.45. There are 70 coins in all. Find how many of each there are
Advocard [28]

There are 47 dimes and 23 quarters.

Step-by-step explanation:

Total amount = $10.45 = 10.45*100 = 1045 cents

Total coins = 70

1 dime = 10 cents

1 quarter = 25 cents

Let,

Dimes = x

Quarters = y

According to given statement;

x+y=70   Eqn 1

10x+25y=1045   Eqn 2

Multiplying Eqn 1 by 10;

10(x+y=70)\\10x+10y=700\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(10x+25y)-(10x+10y)=1045-700\\10x+25y-10x-10y=345\\15y=345

Dividing both sides by 15;

\frac{15y}{15}=\frac{345}{15}\\y=23

Putting y=23 in Eqn 1

x+23=70\\x=70-23\\x=47

There are 47 dimes and 23 quarters.
