White raven [17]

Answer: The numbers that would be highlighted are 5,10,15,20,25,30,35,40,45,50,55,60,65,70,75,80,85,90,95,100. They would be highlighted because they are divisible by 5. Only 5 would be a prime number because all the other numbers are divisible by 5 as well so they wouldn't only have 1 and themselves as a divisor.

Mr. Levy has a budget of $18,000. Uniforms for the marching band cost $315 each, and he needs 62 uniforms. He says, "Since 60x$3
svetoff [14.1K]

Answer:

No. See explanation  below.

Step-by-step explanation:

No.

Since 60 × $300 = $18,000, he would be exactly at budget if he needed 60 uniforms and if each uniform cost $300, but he needs more than 60 uniforms, and each uniform costs more than $315, so the total cost is definitely more than $18,000.

Manuela solved the equation 3−2|0.5x+1.5|=2 for one solution. Her work is shown below. 3−2|0.5x+1.5|=2 −2|0.5x+1.5|=−1 |0.5x+1.5
forsale [732]

Answer:

x=-4

Step-by-step explanation:

The given equation is

3-2|0.5x+1.5|=2

Subtract 3 from both sides.

3-2|0.5x+1.5|-3=2-3

-2|0.5x+1.5|=-1

Divide both sides by -2.

\dfrac{-2|0.5x+1.5|}{-2}=\dfrac{-1}{-2}

|0.5x+1.5|=0.5

If |x|=a, then x=a or x=-a.

0.5x+1.5=\pm 0.5

Case 1: 0.5x+1.5=0.5

Subtract 1.5 from both sides.

0.5x=0.5-1.5

0.5x=-1

Divide both sides by 0.5.

x=-2

Case 2: 0.5x+1.5=-0.5

Subtract 1.5 from both sides.

0.5x=-0.5-1.5

0.5x=-2

Divide both sides by 0.5.

x=-4

Therefore, one solution is x=-2 and other solution is x=-4.
