4(2x - 5) + 15 = 11 Write the steps you will use to solve the equation and explain each step.
vagabundo [1.1K]
First, multiply 4*2x-4*-5= 8x-20.
Second, add 15 to 8x-20
Third, that would equal 8x-20+15=11 
Fourth, 15+-20= -5 
Fifth, 8x-5=11
Sixth, add +5 to -5 and +5 to 11= 8x=16 
Last, do 8x/8x and 16/8x 
The answer is x=2

Advocard [28]
$4.50.

Total with tax = 1.06x = 16.43
X = 15.50 = total before tax

15.50 - 6.50 = 9 = amount spent on both bottles.

9/2 = 4.5 = amount spent on one bottle.

MathUp Evaluating Expressions
AysviL [449]

Since the question is incomplete, answer will be subjective. An example of Evaluating Expressions is find h + 8 − 9 j − h; where h = 7 and j = 5.

<h3>What is the Evaluating Expressions?</h3>

The evaluating expressions  is known to be a form of digital and printable board work that can help students in working on substituting values in terms of variables of an algebraic expression.

Evaluating the Expression below:

h + 8 − 9 j − h;

Therefore, where h = 7 and j = 5

7+ 8 − 9 (5) − 7.

SO: 7 + 8 - 45 -7

=  -37

Therefore the answer to the Evaluating Expression is -37.

14. A unfair coin has the probability of heads
Hitman42 [59]

Answer :

the probability of tossing three heads in a row

=\left( \frac{3}{8} \right)^{3}  =\frac{27}{512} =0.052734375

…………………………………………

the probability of tossing two heads followed by one tail

=\left( \frac{3}{8} \right)^{2}  \times \left( \frac{5}{8} \right)  =\frac{45}{512}

……………………………

the probability of two heads and one tail in any order

=3\times \left( \frac{3}{8} \right)^{2}  \times \left( \frac{5}{8} \right)  =\frac{135}{512}

A hockey coach was taking her team out to a picnic lunch to celebrate their first win. She made 15 sandwiches, 6 of which were t
alexira [117]

The probability that exactly 3 of the chosen sandwiches are turkey is; 0.004

<h3 /><h3>How to find the probability combination?</h3>

We are given;

Total number of sandwiches = 15

Number of sandwiches that were turkey = 6

Now, she selects 6 of the sandwiches and we want to find the probability that exactly 3 are turkey.

Now, number of ways of selecting 6 sandwiches is; 15C6

Number of ways of selecting 3 turkey's out of the 6 chosen is; 6C3

Thus, the probability that exactly 3 of the chosen sandwiches are turkey is; 6C3/15C6 = 20/5005 = 0.004
