Mathematics
1 answer:
Aleks04 [339]3 years ago
5 0

Answer:

The first integer is -2.

The second integer is -1.

Step-by-step explanation:

The five-step method is GUESS method.

Given:

6 times the sum of 2 consecutive integers is 13 less than five times the larger integer.

Unknown:

Value of first and second integer.

Let the first integer be x.

Therefore, the second integer is equal to x+1 which is also the larger integer.

Evaluate:

6 times the sum of first and second integers is 13 less than five times the larger integer. So,

6(x+x+1)=5(x+1)-13\\6(2x+1)=5x-5+13\\12x+6=5x-8\\12x-5x=-8-6\\7x=-14\\x=-\frac{14}{7}=-2

Substitute and Solve:

Now, we have, x=-2.

Substitute -2 for x and solve for first and second integers. This gives,

The first integer value = x=-2

The second integer value = 1+x=1+(-2)=1-2=-1

Therefore, the first integer is -2 and the second integer is -1.

explain how to solve for the missing side from the similar figures given and solve. (do not just give the answer)
Paha777 [63]

Answer:

x=14

Step-by-step explanation:

Since the triangles are similar, you first line up the sides. Then, because the 16 and the 24 line up together, you divide them to find out how much bigger the first triangle is, which is 3/2 or 1.5. After that, you can see that the 21 and the x are on the same side, so you would divide 21 by 1.5 or 3/2 to get x. 21÷1.5=14.

x=14

HELP ME PLEASEEEEEEEEE
Nataliya [291]

Answer:

a)This solution matches with the original equation and its solution

b)This solution matches with the original equation and its solution

c)This solution <em><u>does not</u></em> match with the original equation and its solution. Though the solution is correct the original given equation cannot be used.

d)This solution <em><u>does not</u></em> match with the original equation and its solution. Though the solution is correct the original given equation cannot be used.

Step-by-step explanation:

i) Which scenarios can be solved by 1.5x +  2.25 = 12.75. Select all that apply and note the given solution.

therefore 1.5x = 10.5   therefore x  = 7

a) let the number be x

   therefore if \frac{3}{2} x + \frac{9}{4}  = \frac{51}{4}  \Rightarrow  1.5x + 2.25 = 12.75  then the number x = 7.

 This solution matches with the original equation and its solution

b.) If a taxi driver charges a flat fee of $2.25 and $1.5 per mile, where the

     number of mile = x, then the number of miles Juan can ride the taxi for

     $12.75 is x = 7.

This solution matches with the original equation and its solution

c)if nine quarters of a number, say x, increased by three halves is fifty one

   quarters, the number is x = 5,

   \frac{9}{4} x + \frac{3}{2}  = \frac{51}{4}  \Rightarrow  9x = 51 - 6 = 45 \therefore x = 5

This solution <em><u>does not</u></em> match with the original equation and its solution. Though the solution is correct the original given equation cannot be used.

d.)   If a taxi driver charges a flat fee of $1.5 and $2.25 per mile, where the

     number of mile = x, then the number of miles Juan can ride the taxi for

     $12.75 is x = 5.

2.25x + 1.5  = 12.75  \Rightarrow  9x = 51 - 6 = 45 \therefore x = 5

This solution <em><u>does not</u></em> match with the original equation and its solution. Though the solution is correct the original given equation cannot be used.

An electricity company charges its customers a fixed base charge of $6 a month, plus 10 cents per kilowatt-hour (kWh) for the fi
ryzh [129]

Answer:

E(k)= \left[ \begin{array}{c} {6+0.10k\,\,if\,\,0\leq k \leq500} & 6+500\times0.10+0.11(k-500)\,\,if\,\,5001000\end{array}

Step-by-step explanation:

The cost function has 3 branches,

  1. Consumptions less than 500
  2. Consumptions less than 1000
  3. consumptions above a 1000

So the first branch the consumer pays 6 dollars plus .10cents for any additional kWh (k)

In the second, they pay the same as the first up to 500kWh, and after that they pay  0.11 for the additional kWh above 500: (k-500) but bellow 1000

In the third branch, for consumptions above 1000, they pay the fix amount, plus .10 for the first 500 (500\times0.10) , .11 for the additional 500 (500\times0.11) , and finally 0.15 for consumptions above 1000: 0.15(k-1000)
