Sam wants to leave an 18% tip for his dinner. The bill is for $23.50. Which equation could be used to find the total amount that
lora16 [44]

Answer:

(0.18 x 23.50) + 23.50

Step-by-step explanation:

First, find the percentage of 23.50 (equation in the parenthesis). 18% is equivalent to 0.18. Then, you add that to 23.50. That's the total amount Sam should pay. I hope this makes sense.

What’s the answer to 4x(x+3) < -24
NARA [144]

The answer to the inequality is expressed as x< 1 and x< -4

<h3>What are inequalities?</h3>

Inequalities are mathematical expressions having both sides unequal or rather not equivalent to each other.

Given the inequality;

4x (x+3) < -24

First, expand the bracket

4x² + 12x < -  24

Let's turn to quadratic inequality

4x² + 12x - 24 < 0

Factorize further

4 ( x² + 3x - 4) < 0

4 ( x² + 4x - x - 4) < 0

4 ( x(x + 4) - 1 (x + 4) ) < 0

4(x - 1) ( x + 4) < 0

expand the bracket

4x - 4 < 0

x < 1

And

4x + 16 < 0

x < -4

Thus, the answer to the inequality is expressed as x< 1 and x< -4

I really need help, struggling. Question is in image. ​
Dominik [7]

Answer:

164

Step-by-step explanation:

Checkpoint 2= -187

Checkpoint 1= -23

The negatives mean how much lower they are from the surface.

To find "how much lower," we need to subtract -23 from -187.

-187-(-23) is the same as -187+23 (2 negatives=1 positive)

-187+23= -164.

However, it's not negative in the answer because by asking how much lower, we don't need to have a negative. "How much lower" is a distance, and a distance is always positive.
