Answer 1

Answer:

1) Expression

2) Equation

3) Equation

4) Expression

Step-by-step explanation:

An equation always contains an equal sign, so in this case, if it doesn't contain an equal sign, it's an expression.

For 2 and 3, you can see that there is an equal sign, but for 1 and 4, there is not.

Therefore, 1 and 4 are expressions and 2 and 3 are equations.

I hope this helped.

Answer 2

5x+2(x+3) is an expression

5x=2(x+3) is an equation

8m-3m+5=16 is an equation

8m-3m+5-16 is an expression

An equation always and I mean ALWAYS uses a = sign.

An expression is a combination of numbers and variables and symbols.

Hope that's useful

You are filling piñatas for your sister's birthday party. The list shows the gifts you are putting into the piñatas. You want identical groups of gifts in each piñata with no gifts left over. What is the greatest number of piñatas you can make?

Answers

Answer:

The greatest number of piñatas you can make with the gifts is:

6 piñatas.

Step-by-step explanation:

To identify the greatest number of piñatas, you must think in a number that can divide another and obtain a whole number with this:

182442

Bigger the number, greater the number of piñatas, in this case, you can see the numbers given can be divided into four numbers obtaining a whole number: 1, 2, 3, and 6. Remember that the best number is the greatest, in this case, number six. Now you proceed to divide the numbers into 6:

[tex]\frac{18}{6}= 3[/tex][tex]\frac{24}{6}= 4[/tex] [tex]\frac{42}{6}=7[/tex]

Taking into account the values obtained, you can see that each piñata would have: 3 bottles of nail polish, 4 pairs of earrings, and 7 lollipops.

Hope this helped :)

Answer:

Please see explanation.

Step-by-step explanation:

-4(x+6) + 2(x-2)   First, distribute the -4 to x+6

-4x - 24 + 2(x-2)   Now distribute the 2 into x-2

-4x - 24 + 2x - 4   Combine like terms

-4x + 2x - 24 - 4

-2x - 28                  This might be your answer but if you are looking for what x is equal to then keep following along.

If you are solving for x then most likely the equation says that it is equal to zero

-2x - 28 = 0   Add 28 to both sides

-2x = 28        divide both sides by -2

x = -14

You and your soccer team are interested in buying jerseys. The price of each jersey is $50. If you buy 4 jerseys, you will get 10% discount. How much do you have to pay if you buy 8 jerseys?

Answers

Answer: $4.84

Explanation:

County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$75 * 0.0725 = $5.4375

Add the original price and the sales tax.

$75 + $5.4375 = $80.4375

County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$70 * 0.08 = $5.6

Add the original price and the sales tax.

$70 + $5.6 = $75.6

Then take the difference.

80.4375 – 75.6 = 4.8375

Round to the nearest hundredth: $4.84

A box of Shredded Wheat weighs 0.35 kg and a box of Weetabix weighs 9/25 kg?

Which box is heavier?

Show your work

PLEASE HELP DUE TONIGHT THANK YOU SO MUCH

Answers

Answer:  The box of Weetabix is heavier by 0.01 kg

Step-by-step explanation:

Divide 9/25 to get the decimal equivalent

9÷25 =0.36

Compare Shredded Wheat at 0.35 kg to Weetabix at 0.36 kg

Weight of the box of Shredded Wheat is [tex]0.35[/tex] kg and weight of the box of Weetabix is [tex]0.45[/tex] kg.

So, the box of Weetabix is heavier.

Weight of the box of Shredded Wheat [tex]= 0.35[/tex] kg.

Weight of the box of Weetabix [tex]= \frac{9}{25}[/tex] kg.

Here to compare the two weights, first make both of them similar.

Either make both of them decimals or both of them fraction.

Here, we will make both the weights decimals.

[tex]\frac{9}{20} = 0.45[/tex]

Now, [tex]0.45>0.35[/tex]

So, the box of Weetabix is heavier.

Records on a fleet of trucks reveal that the average life of a set of spark plugs is normally distributed with a mean of 22,100 miles. A manufacturer of spark plugs claims that its plugs have an average life in excess of 22,100 miles. The fleet owner purchased 18 sets and found that the sample average life was 23,400 miles, the sample standard deviation was 1,500 miles and the computed test statistic was 3.677. Based on these findings, there is enough evidence to accept the manufacturer's claim at the 0.05 level.

Answers

Answer:

There no sufficient evidence to support the manufactures claim at the 0.05 level

Step-by-step explanation:

From the question we are told that

   The  mean is  [tex]\mu = 22100 \ miles[/tex]

    The  sample mean is [tex]\= x = 23400 \ miles[/tex]

   The  sample size is  [tex]n  = 18[/tex]

   The standard deviation is [tex]\sigma  =  1 500 miles[/tex]

    The test statistics is  [tex]t = 3.677[/tex]

    The level of significance is [tex]\alpha  =  0.05[/tex]

The null hypothesis  is  [tex]H_o :  \mu =  22100[/tex]

The  alternative hypothesis  is  [tex]H_a :  \mu  \ne 22100[/tex]

Generally the p-value  is mathematically represented as

     [tex]p-value  =  2 *  P(t >3.677 )[/tex]

From the z-table  [tex]P(t >3.677 )  =  0.000118[/tex]

So

    [tex]p-value  =  2 *  0.000118[/tex]

=> [tex]p-value  =  0.000236 [/tex]

From he value given and obtained we see that  [tex]p-value  <  \alpha[/tex]

Hence we reject the null hypothesis

Hence there no sufficient evidence to support the manufactures claim

A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbers included on the line determine how it’s meant to be used.

In order to find the square root of 10 lies between which two numbers the approximate value of the root is needed to be calculated.

√10 = 3.162.......

Now, if we plot √10 on the number line its value will lie between 3 and 4.

You buy milk that contains 180 calories per 2 cups. Use a ratio table to find the number of calories in 18 cups.

Answers

Answer:

1620

Step-by-step explanation:

180/2=90

90*18=1620

You buy milk with 180 calories in two glasses. Now compute the caloric value of 18 cups. 18 cups contain 1620 calories.

What is meant by caloric value?Calorific value, also known as heating value or heat of combustion, is a unit of measurement for the total energy content produced in the form of heat when a substance is completely combusted with air or oxygen. The amount of heat energy released during complete combustion of a unit mass of a fuel is defined as its calorific value. It is measured in kJ/kg.It is the measurement of the heat value or amount of energy released, and it is expressed in either gcv or ncv. Gross calorific value (GCV), also known as Higher Heating Value (HCV), is the amount of heat released by complete combustion when a unit of fuel is burned.

Therefore,

You buy milk with 180 calories in two glasses.

Now compute the caloric value of 18 cups.

Let 18 cups have a calorie count of As, and 2 cups have 180 calories.

A serving of two cups contains 180 calories.

As a result, the ratio would be 2: 180.

As a result, 18 cups contain X calories.

18 cups are equal to X calories.

Consequently, the ratio would be  X : 18

We now set a ratio to determine how many calories are in 18 cups:

2 : 180  ::  18  : X

Simplifying,

2/ 180 = 18/X

Cross multiplying results in:

2X = 18 × 1 80

= 3240

By multiplying both sides by 2, we obtain:

X = 3240/2

= 1620

Hence, 18 cups have 1620 calories in them.

Scott runs 3 km in 30 minutes and then rests for 15 minutes. He then runs 2 km in 15
minutes. What was Scott's average speed?

Answers

Answer:

5km/hr

Step-by-step explanation:

Given

Distance = 3km and 2km

Time = 30 mins, 15 mins, 15 mins

Required

Determine the average speed

To answer this, we need to determine the total distance.

Distance =3km + 2km = 5km

Then, we calculate the total time

Time = 30 mins + 15 mins + 15 mins = 1 hr

Next, we can now determine the average speed using:

Average Speed = Total Distance/Total Time

Average Speed = 5km/1 hr

Average Speed = 5km/hr

0.6x = 0.1x + 12

take away 0.1x from both sides:

0.5x = 12

divide both sides by 0.5
