So when this sign < has a line under the greater sign so this mean greater or equal 

same with this 

12>= x so this mean 12 greater or equal x but than there is a line under the greater sign so this mean equalitie sure too 

hope this will help you

Odd number, greater than 142, less than 156, what is the mystery number
TiliK225 [7]
145 will work. It is an odd number and is greater than 142 and is less than 156

142 < 145 < 156

Other numbers such as 143, 147, 149,151,153, 155 will work.

What is the justification for step 4 in the solution process?
iogann1982 [59]

Answer:

Multiplication property of equality

Step-by-step explanation:

Given

Step 4: b = -27/8

Required

Which property justifies it?

First, it should be noted that step 4 is a result of step 3

When step 3 is multiplied by 3/8 on both sides, we have step 4;

i.e.

\frac{8}{3b} = -9

\frac{8}{3b} * \frac{3}{8} = -9 * \frac{3}{8}

b = -9 * \frac{3}{8}

b = \frac{-9 * 3}{8}

b = \frac{-27}{8}

<em>The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality</em>

ZP bisects ∠OZQ so that ∠OZP = 8x – 9 and ∠PZQ = 5x + 18. Find the value of x, and the measure of each angle. You must show all
Assoli18 [71]
<span>x = 9 Since ZP bisects â OZQ, that means that the measurements for â OZP and â PZQ are the same. So create an equation with their respective values set to each other. 8x - 9 = 5x + 18 Now solve for x 8x - 9 = 5x + 18 Subtract 5x from both sides 3x - 9 = 18 Add 9 to both sides 3x = 27 Divide both sides by 3 x = 9</span>

Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25^30.25 m
Vladimir [108]

Answer:

Gold

Step-by-step explanation:

<em>Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25 cubic meters. The coins have a combined mass of 4825 kg. Hoping to find gold, she calculates the density to determine the metal of the coins.</em>

<em>What kind of metal are the coins made of?</em>

<em>Bronze (8700 kg per cubic meter)</em>

<em>Silver (10500 kg per cubic meter)</em>

<em>Lead (11300 kg per cubic meter)</em>

<em>Gold (19300 kg per cubic meter)</em>

<em />

Density is mass per volume:

D = M / V

D = (4825 kg) / (0.25 m³)

D = 19,300 kg/m³

The coins must be made of gold.
