Mary beth is making 7,763 millilters of punch she uses 3liters 26 millilters of orange juice how many liters of pinapple juice d

AlladinOne [14]

Answer:

<h3> 4.737 litres</h3>

Step-by-step explanation:

Total volume of punch beth is making = 7,763milliliters

If the punch contains the mixture of orange juice and pineapple juice then;

Volume of punch = Volume of pineapple juice + volume of orange juice

If she uses 3 litres 26 millilitres of orange juice.

converting the volume of orange juice to millilitres (1 litre = 1000 millilitres)

Volume of orange juice = 3000 millilitres + 26 millilitres = 3,026 millilitres

Volume of pineapple juice needed = Total volume of punch - Volume of orange juice

Volume of pineapple juice needed = 7,763 - 3,026

Volume of pineapple juice needed = 4,737millilitres

Converting the volume of pineapple to litres = 4,737/1000 = 4.737litres

The amount of liters of pineapple juice mary beth need to add to complete her punch is 4.737 litres

There is a 10% off sale on laptop computers. If someone saves $35 on a laptop, what was its original cost?

IceJOKER [234]

Answer:

The original cost is $350

Step-by-step explanation:

Let's assume

original cost of computer is x

There is a 10% off sale on laptop computers

So, amount saved is

$=\frac{10}{100}x=0.10x$

now, we are given

someone saves $35 on a laptop

so, we can set them equal

and then we can solve for x

$0.10x=35$

we can divide both sides by 0.10

and we get

$x=350$

So,

The original cost is $350

PLEASE HELP!!!!!! the sum of a number times 10 and 15 is at most -17

Brilliant_brown [7]

Let the number = x

Writing the equation you have:

10x + 15 <= -17

Solve for x

Subtract 15 from both sides:

10x <= -32

Divide both sides by 10:

X <= -32/10

Simplify:

X <= -16/5 as a fraction or -3.2 as a decimal
