What inequality represents the sentence? The product of a number and 12 is no more than 15.

1 answer:

7 0

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.

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

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

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

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

$b = \frac{-27}{8}$

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

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]

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

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:

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.

What kind of metal are the coins made of?

Bronze (8700 kg per cubic meter)

Silver (10500 kg per cubic meter)

Lead (11300 kg per cubic meter)

Gold (19300 kg per cubic meter)

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.
