Answer: x=2 Please mark as brainliest

Step-by-step explanation: 16+7+4x=x+3x+7

combine like terms: 23+4x=4x+7

get x to one side: 23=8x+7

subtract: 16=8x

divide: x=2

jemboy wants to make his 8 meter square pool into a rectangular one by increasing its length by 2m and decreasing its width by 2

mel-nik [20]

Side = 8m
He increases length by 2m and reduces width by 2m
(a.) New dimensions will be -
Length = 10m and Width = 6m
(b.) Area = length x breadth (or width)
here we will use the special product (x+y) (x-y)
length = (x+y) and width = (x-y)
area = (8+2) x (8-2)
8^(2) - 2^(2)
= 60

Find the table with unit rates greater than the unit range in the graph. Then arrange these tables in order from least to greate

Lubov Fominskaja [6]

Answer:

Except table 2, all tables have greater unit rate than the graph.

The required arrangements of tables is

Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < table 7 < Table 6

Step-by-step explanation:

Formula for unit rate :

$m=\dfrac{y_2-y_1}{x_2-x_1}$

From the given graph it is clear that the line passes through the points (0,0) and (11,20). So, unit rat of graph is

$m=\dfrac{20-0}{11-0}=1.8181...$

Similarly, we need to calculate the unit rate for each table.

$m_1=\dfrac{26-13}{14-7}=\dfrac{13}{7}=1.85714$

$m_2=\dfrac{18-9}{10-5}=\dfrac{9}{5}=1.8$

$m_3=\dfrac{34-17}{18-9}=\dfrac{17}{9}=1.88..$

$m_4=\dfrac{42-21}{22-11}=\dfrac{21}{11}=1.9090..$

$m_5=\dfrac{38-19}{20-10}=\dfrac{19}{10}=1.9$

$m_6=\dfrac{50-25}{26-13}=\dfrac{25}{13}=1.923$

$m_7=\dfrac{46-23}{24-12}=\dfrac{23}{12}=1.9166..$

Except table 2, all tables have greater unit rate than the graph.

The required arrangement of tables is

Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < Table 7 < Table 6

<h3><u>Fraction to Decimal:</u></h3>

Divide the numerator (upper number) by the denominator (bottom number) on your calculator. Whatever number you get would be your decimal.

<h3><u>Decimal to Percent:</u></h3>

Take your decimal and use your calculator to multiply it by 100. Whatever number you get would be your percent. However, since it is a percent, you need to include the percentage unit.

<h3><u>Demonstration:</u></h3>

1/4 = 0.25

0.25 * 100(%) = 25%

Liliana used 444 dark power crystals to raise 141414 zombie soldiers. She wants to know how many zombie soldiers (z)(z)left pare

Mariulka [41]

Question is bit incorrect, Correct question is given below.

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) she can raise with 10 dark power crystals. How many zombie soldiers can Liliana raise with 10 power crystals?

Answer:

Liliana can raise 35 zombie soldiers.

Step-by-step explanation:

Let the number of zombie soldiers raised by 10 dark power crystals be 'z'.

Zombie raised by 4 power crystals = 14

Since the number of zombie and power crystals are in direct proportion.

Therefore, we get

$\frac{z}{10}=\frac{14}{4}$

Multiply 10 on both the sides, we get

$z=\frac{14}{4}\times 10 = 35$

Hence, Liliana can raise 35 zombie soldiers.
