Answer:

The product of (-4)(7) is -28 because you are removing 4 times, the number 7

.

Reason is below.

Step-by-step explanation:

The number which is written first in the multiplication or the product is always multiplied by the second number.

For example

3 × 2 implies three times two which equal to 6

2 × 3 implies two times three which is also equal to 6

Therefore the number written in the first is count as times, the number second.

For example

-3 × 2 implies three times two which equal to -6

Here the product is negative 6

Because if a negative number is multiplied by positive number you will always get the product as negative number.

If a positive numbers multiplied by positive number you will always get the product as a positive number.

For example

3 × 2 implies three times two which equal to 6

If a positive numbers multiplied by negative number you will always get the perfect as a negative number.

For example

3 × -2 implies three times two which equal to -6

If a negative number is multiplied by negative number you will always get the product as a positive number.

For example

-3 × -2 implies three times two which equal to 6

Therefore, the product of (-4)(7) is -28 because you are removing 4 times, the number 7

Adante begins to evaluate the expression 3 1/3 x 5 1/4 using the steps below
il63 [147K]

Answer:

\frac{35}{2}

Step-by-step explanation:

To solve this problem we need to write the mixed fraction as a fractional number, as follows:

3 1/3 = 3 + \frac{1}{3} = \frac{9+1}{3} = \frac{10}{3}

5 1/4 = 5 + \frac{1}{4} = \frac{20+1}{4} = \frac{21}{4}

Then, evaluating the expression:

\frac{10}{3}×\frac{21}{4} = \frac{210}{12} =  \frac{35}{2}

A student solved 6x+4=2(x−8) in four steps as shown:
mr_godi [17]
The first thing you should do is solve the equation yourself.

1) Distribute the 2.  
6x + 4 = 2x – 16

2) Next, you'll want to get the x's on one side. So add -2x to both sides.
6x + 4 + -2x = 2x + -2x - 16
4x + 4 = -16

3) Now subtract 4 from both sides
4x + 4 – 4 = -16 – 4
4x = -12

4) Finally, divide both sides by 4
4x/4 = -12/4
x = –3

To solve this problem all you need to do is look back out you work, and figure out the correct solution. The answer the question is The student made an error in Step 1.
