Answer:

5x4=20

Step-by-step explanation:

The expression says that 20 is 4 times as many as 5, what is the same as 4 times as many as 5 is equal 20.

The meaning of the expression, if we put into equation terms, is:

4 times 5 is equal to 20

So, we can write the following equation for this expression:

4 x 5 = 20

5 x 4 = 20

So, the answer is the first option:

5x4=20

Answer:

The answer is 20 = 4*5.

Step-by-step explanation:

An equation is an mathematical expression where two things are equal. In this case we have a number and an product. The problem states that 20 is 4 times as many as 5. The "is" word gives us a hint that there is the equal sign, and the "times" gives us a hint that it is a product. So we can express this with:

20 = 4*5

Wich would be the first possible answer.

Answer:

The left end approaches to + Infinite being an exponential function, and the right end to 0

Step-by-step explanation:

we have to remember the exponential function, the best way to find the answer is plotting the graph or arranging a table of values.

As you can see in the attached graph the y axis gets closer and closer to 0 as it moves forward in the x axis, and as it moves to the left the y axis starts increasing rapidly.

Also you got to keep in mind the way that functions behave in terms of the sign of its variable. for example the 10 in this equation only makes the curve to get wider, but if you change the sign to minus, the answer would be different.

terry opened a savings account in December with $132 and saved $27 each month beginning in January the value of terrys account i

liq [111]

Let S be the amount in a savings account.
Let m be the number of months.

General equation
S = 132 + 27m

Specific question
July is the 7th month of the year including both January and July.
S = 132 + 7*27
S = 132 + 189
S = 321

Reasonableness?
Good question. You could estimate an answer.
Start with 150 dollars and say that you add 25 a month.
7 * 25 = 175
S = 150 + 175 = 325 All of this was done in my head. Since the exact answer obtained using the formula is 321, I think that's pretty reasonable using my estimate is a guide.

The length of a rectangular picture frame is 2 inches shorter than its width. If the perimeter of

jok3333 [9.3K]

Answer:

Length = 12 inches

Width = 14 inches

Step-by-step explanation:

Formula for perimeter of a rectangle is;

P = 2(L + W)

Where;

L is length

W is width

We are told that the length is 2 inches shorter than its width. Thus;

L = (W - 2)

Thus,perimeter is now;

P = 2(W - 2 + W)

P = 2(2W - 2)

P = 4W - 4

We are told that the perimeter is 52. Thus;

4W - 4 = 52

4W = 52 + 4

4W = 56

W = 56/4

W = 14 inches

From L = (W - 2) ;

L = 14 - 2

L = 12 inches
