Answer:

800 Laptops

Step-by-step explanation:

3:2 = 1200:x

I first divide 1200 with 3 because that is the ratio of the students. WE can see that 1200/400 equals 3. So if I multiply 2 times 400, then we get 800 Laptops.

1.5 lbs of gum balls I want to buy it’s 3.99 per pound
zubka84 [21]

Answer:

$5.99 for 1.5 lbs of gumballs

Step-by-step explanation:

You want to buy One and a half pounds of gumballs for $3.99 per pound. It is 3.99 for one pound of gumballs, so the price for half a pound of gumballs is half of that price.

3.99 / 2 = 1.995

Then add the price of 1 pound

3.99 + 1.995 = 5.985

Then you can round that up to 5.99

What is the value of the expression below when x=3<br> 10x²- 7x + 10
Andreas93 [3]

Answer: 79

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

<u>Given information</u>

10x² - 7x + 10

x = 3

<u>Substitute the value into the expression</u>

= 10 (3)² - 7 (3) + 10

<u>Simplify by multiplication</u>

= 10 (9) - 21 + 10

= 90 - 21 + 10

<u>Simplify by subtraction</u>

= 69 + 10

<u>Simplify by addition</u>

= 79

Hope this helps!! :)
