Answer:

x = 5

Step-by-step explanation:

2⁴(2x) = 2⁵(x + 3)

2^8× = 2^5x + 15

8x = 5x + 15

8x - 5x = 15

3x = 15

divide through by 3

x = 5

3. There are 6645 students at Tech Middle School, and
20% of the stredents are 7th graders.
How
many
Students are 7th graders?

Answers

Answer:

.20

Step-by-step explanation:

The word percent literally means "Out of 100". With that being said, 20% can be written as a fraction, mixed number or whole number as follows: 1/5 (fraction), 20/100 (mixed number) or .20 (whole number).

Answer:

1329 students

Step-by-step explanation:

20/100 ×6645

Reduce the fraction 20/100 with 20

So..20 goes into 20 1 time and 20 into 100 5 times

1/5×6645

Use 5 as the greatest common factor now

so...5 into 5 goes 1 time and 5 into 6645 goes 1329

1/1 × 1329 = 1329

Or... you could just convert 20% into a decimal by carring the . two places to the left

which is 0.2

x=90-77

x=13

Type the correct answer in the box.

The area of the figure is ___ square units.

Answers

Answer:

26 square units

Step-by-step explanation:

We are given a diagram and are asked to find the area of the figure in square units.

To solve, take in mind that we need to multiply the sides given.

Area is L * W, therefore, we know that our length is 5 by 2 units, while our width is 3 by 2 units.

First start with the length, since it is 5 by 2 we multiply 5 and 2 :

5 * 2 = 10

Then with the width, since it is 3 by 2, we can multiply 3 and 2 :

3 * 2 = 6

Then do the length again since the bottom part of the diagram needs to be included, it is also 5 by 2 :

5 * 2 = 10

Add all these together to get your answer :

10 + 6 + 10

16 + 10

26 square units.
