Find the value of x.<br> xo<br> (x-20)<br> (2x + 10)<br> (x + 40)
kykrilka [37]

Answer:

66

Step-by-step explanation:

We can write the following equation to solve

360 = x + (2x + 10) + (x - 20) + (x  + 40)

Reduce

360 = 5x + 30

5x = 330

x = 66

Tamara says she used the GCF to factor the expression 21x + 56xy as 7(3x + 8xy). Is she correct? Explain.
cestrela7 [59]

Answer:

Tamara  incorrectly factored the whole expression.

Step-by-step explanation:

Note that

  • 21x=3·7·x;
  • 56xy=2·2·2·7·x·y.

Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.

Thus,

21x+56xy=7x(3+8y).

Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.

The linear regression line for Tampa Tribune Database is y=8x+367. In approximately what year is the Tampa Tribune expecting to
lakkis [162]

The Tampa Tribune expecting to add 700 new pictures per year to their database in 2041

<h3>The linear equation of the graph</h3>

The equation of the line of best fit is given as:

y = 8x + 367

When the number of pictures added is 700, we have:

y = 700

Substitute 700 for y in y = 8x + 367

700 = 8x + 367

Subtract 367 from both sides of the equation

333= 8x

Rewrite the above equation as:

8x = 333

Divide both sides by 8

x = 41.625

Remove decimal (do not approximate)

x = 41

This means that:

Year = 2000 +41

Year = 2041

Hence, the Tampa Tribune expecting to add 700 new pictures per year to their database in 2041
