What is the answer to 15-5x2+[4x(3+5)+8]

Mathematics
1 answer:
AlexFokin [52]3 years ago
8 0

Answer: 45

Step-by-step explanation:

I don't know if you mean the "x" as multiplication or as a variable, but I will assume it means multiplication.

First:

Calculate what is inside the brackets ( [ ] )

4x(3+5)+8

=4x8+8

=32+8

=40

Next:

15-5x2+40

=15-10+40

=5+40

=45

Tan weighs 146 pounds. Minh weighs 15 pounds more than Tan. How much does Minh weigh?
dimaraw [331]

Given parameters:

Weight of Tan  = 146pounds

Unknown:

Weight of Minh = ?

Following this problem step wisely, we can derive a solvable algebraic equation;

  Let the weight of Minh  = M

In the second sentence, we see that Minh weighs 15pounds more than Tan;

    So;

              M  = 15 + Weight of Tan

Since we already know the weight of Tan,

  Weight of Minh  = 15 + 146  = 161pounds

We clearly see that Minh's weight will be 161 pounds.

Which ordered pair makes both inequalities true?
kow [346]

An ordered pair which makes both inequalities true is (-1, -3).

<h3>What is an ordered pair?</h3>

An ordered pair is a pair of two points that are commonly written in a fixed order within parentheses as (x, y), which represents the x-coordinate or x-axis (abscissa) and the y-coordinate or y-axis (ordinate) on the coordinate plane of any graph.

Next, we would test the ordered pair with the given system of inequalities in order to determine which is true.

For ordered pair (-3, 5), we have:

y < –x + 1

5 < -(-3) + 1

5 < 3 + 1

5 < 4 (False).

For ordered pair (-2, 2), we have:

y < –x + 1

2 < -(-2) + 1

2 < 2 + 1

2 < 3 (True).

y > x

2 > -2 (True)

For ordered pair (-1, -3), we have:

y < –x + 1

-3 < -(-1) + 1

-3 < 1 + 1

-3 < 2 (True).

y > x

-3 > -1 (False)

For ordered pair (0, -1), we have:

y < –x + 1

-(-1) < -(0) + 1

1 < 1

1 < 1 (False).

y > x

-1 > 0 (False)
