With 128, 134, 140, 146, 152, what’s the next number if the pattern continues?

prohojiy [21]

<span>So we are looking for the next number in the number sequence after the number 152. Since 134-128=6, 140-134=6, 146-140=6, 152-6=146 we can clearly see that the pattern is to add number six to each term of the sequence: 152+6=158 is the correct answer.</span>

Nathaniel bought 3 hamburgers and 2 orders of fries for $12.50. Liam bought 2 hamburgers and 4 orders of fries for $13. How much

Nina [5.8K]

The cost of an order of 1 hamburger and 2 orders of fries cost which Nathaniel and Liam bought is $6.5.

<h3>What is system of equation?</h3>

A system of equation is the set of equation in which the finite set of equation is present for which the common solution is sought.

Let the cost of 1 hamburger is x dollar and 2 orders of fries is y dollars. Nathaniel bought 3 hamburgers and 2 orders of fries for $12.50. Thus,

$3x+2y=12.5$

Solve this equation as,

$2y=12.5-3x\\y=\dfrac{12.5-3x}{2}$ .....1

Liam bought 2 hamburgers and 4 orders of fries for $13. Thus,

$2x+4y=13$

Put the value of y in this equation and solve it further,

$2x+4(\dfrac{12.5-3x}{2})=13\\2x+25-6x=13\\-4x=13-25\\-4x=12\\x=\dfrac{12}{4}\\x=3$

Put this value of x in equation 1,

$y=\dfrac{12.5-3\times3}{2}\\y=\dfrac{3.5}{2}\\y=1.75$

The cost of an order of 1 hamburger and 2 orders of fries is,

$C=3\times 1+2\times1.75\\C=3+3.5\\C=6.5$

Thus, the cost of an order of 1 hamburger and 2 orders of fries cost which Nathaniel and Liam bought is $6.5.

What is the expected price of a calculator in the year 2000 if it costs $17.6 in 2015? You can use the chart below for a referen

Aleks04 [339]

Answer:

$12.78.

Step-by-step explanation:

To determine the expected price of a good in 2000, knowing that in 2015 it cost $ 17.6 and that the consumer price indexes were worth 172.2 in 2000 and 237.017 in 2015, the following calculation must be performed:

237.037 = 17.6

172.2 = X

X = 172.2 x 17.6 / 237.037

X = 3,030.72 / 237.037

X = 12.78

Thus, the expected price of the good in the year 2000 is $ 12.78.

A school book fair has 72 non fiction books and 328fiction books for sale. What percent of the book fair is non fiction books

Varvara68 [4.7K]

Answer:

18%

Step-by-step explanation:

Non fiction books - 72

Fiction Books - 328

Total Books - 400

72 + 328 = 400

Percent of non fiction books to book fair - 18%

$\frac{72}{400}$

Simplify it until it has a denominator of 100, since that is the standard denomination for percentages.

$\frac{18}{100}$

18% or 0.18.
