Which inequality is equivalent to -m 2 15?

inysia [295]

The correct answer is option 3: m≤-15

Step-by-step explanation:

The inequalities are solved by performing operations on both sides of inequality

Given inequality is:

$-m\geq 15$

when an inequality is multiplied by -1 the signs of numbers on both sides are changed while the inequality operator is also reversed.

Multiplying both sides by -1 will give us:

$m\leq -15$

The correct answer is option 3: m≤-15

The prime cost of an article was four times the value of material used. The cost of raw materials was increased in the ratio 3 :

jenyasd209 [6]

Answer:

Step-by-step explanation:

The prime cost = 4 times the value of material used

Former Prime cost = 540

Value of material = 540 / 4 = Rs. 135

Since ;

Prime cost = raw material + wages

540 = 135 + wages

Wages = 540 - 135

Wages = 405

Increase in raw material ; 3 : 4

New cost of raw materials = (4/3) * 135 = 180

Decrease in wage ; 4 : 5

New wage = 4/5 * 405 = 324

New prime cost :

180 + 324

= 504

A carpenter use 65 shelves to make 13 bookcases. She uses the same number of shelves for each bookcase. Are 32 shelves enough to

serg [7]

Answer:

Yes.

Step-by-step explanation:

First, find the unit rate for 1 bookcase.

65 ÷ by 13 = 5 (unit rate)

Then, multiply the unit rate by the bookcases the carpenter wants to make.

6 · 5 = 30

Finally, subtract the shelves the carpenter wants to use by 30.

32 - 30 = 2 shelves.

Therefore, 32 shelves is enough to build 6 more bookcases. <3
