Answer:

[tex]x > -3[/tex]

Step-by-step explanation:

Isolate the variable. Treat the < sign like an equal sign, in that what you do to one side, you do to the other.

Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

First, subtract 60 from both sides of the equation:

-15x + 60 (-60) < 105 (-60)

-15x < 45

Next, divide -15 from both sides of the equation. Note that when you multiply or divide a negative number, you must flip the sign:

(-15x)/-15 < (45)/-15

x < 45/(-15)

x > -3

[tex]x > -3[/tex] is your answer.

(subtract 55 from both sides)

y = 35

Answer:

Step-by-step explanation:

Let q represent the number of quarters, and d represent the number of dimes.

  0.25q +0.10d = 4.20 . . . . . the value of the coins

  q = 2d . . . . . . . . . . . . . . . the relation between the numbers of coins.

__

Additional comment

Using substitution, the equation simplifies to ...

  0.60d = 4.20

  d = 7

  q = 14

Note that the coins can be grouped into groups of 2 quarters and 1 dime. The value of the group is $0.60, and the number of dimes is equal to the number of groups. Thinking about the problem in this way gets you immediately to the single equation 0.60d = 4.20.

Answer:

64 ft

Step-by-step explanation:

A square has to be equal on all 4 sides for it to be considered a square. Considering that it is 8 feet on one side it would be 8 feet on all the others as well. From there you multiply 8*8 and receive the solution of 84 feet for the area of the garden.

The number of ways Molly can arrange the tomato plants in an array is 27,907,200 ways

Find the image attached. From the figure, we can see that there are 6 rows in the array.

If there are 20 tomato plants, the ways Molly can arrange the tomato plants in an array is expressed according to the permutation formula:

20P6 = 20!/(20-6)!

20P6 = 20!/14!

20P6 =  20 * 19 * 18 * 17 * 16 * 15

20P6 = 27,907,200

Hence the number of ways Molly can arrange the tomato plants in an array is 27,907,200 ways

Answer: 240 gumdrops

Answer:

Step-by-step explanation:

Use the slope formula to solve this problem. Slope, usually called m, is the change in y-values over the change in x-values.

m = (y2 - y1)/(x2 -x1)

It actually doesn't matter which point is the first point and which point is the second point. But you must be consistent.

So fill in -3/2 for the m

Let your (6, b) be your (x1, y1)

Let (-2, 4) be your (x2, y2)

So, the numbers fill into the formula like so:

-3/2 = (4 - b)/ (-2 - 6)

-3/2 = (4 - b)/(-8)

Multiply -8 on both sides of the equation.

(-8)(-3/2) = 4 - b

12 = 4 - b

Subtract 4 from both sides.

Don't lose the negative in front of the b

8 = -b

Multiply or divide by -1 on both sides.

-8 = b This is the answer.

**note: Its kinda crummy to use b in this equation, because b has a special meaning when you are working with linear equations. They should have given you a different variable. b usually stands for the y-intercept but in this problem it doesn't, it's just a variable representing an unknown value.

Step-by-step explanation:

to round 4.645 to the nearest whole number consider the tenths’ value of 4.645, which is 6 and equal or more than 5. Therefore, we have to round up: the whole number part of 4.645, 4, increases by 1 to 5, and the decimal point and all digits (.645) are removed.

4.645 rounded to the nearest whole number = 5
