Answer:

10(3w)=6*5

30w=30

w=1

(not sure if youre meant to just have the equation or find w)

13

48°F

14

€1.25

Step-by-step explanation:

12

The floor area is found by multiplying its length by its width: 6*5=30

The amount of area covered by one tile is found by multiplying its length by its width: 3*w=3w.

Ten tiles are used to cover the floor, so the floor area should be equal to ten times the tile area:

10(3w)=6*5

30w=30

w=1

(not sure if youre meant to just have the equation or find w)

13

35°F is 13°F lower than the high temp. So, add 13°F to find the high temp.

35+13=48°F

13) A Super Bowl Party Sub was cut into 3 equal pieces that were x inches long. Kevin took
6 inches of the sub for himself. There was still 30 inches of the sub when the game started.
How many inches was each of the pieces?

Answers

Answer:

12 inches

Step-by-step explanation:

now i am assuming kevin took 6 inches of the sub before the game because it says "there was still 30 inches of the sub when the game started". In that case, add 6 and 30 to get 36. Because the sub was cut into 3 equal pieces, divide 36 by 3 and get 12 inches as your final answer.

There are 80 students total in 7th grade, of whom 15% are left handed. How many
left handed 7th grade students are there?

Answers

15% translates to 15/100 as a fraction.

If you multiply that by the number of student there are (80) you’d get the 15% of students who are left handed.

80(15/100)=12

12 students are left-handed

Mr. Tanner bought some boxes of markers with 18 markers in each box. He kept 2 markers and gave the rest to his students. Use the equation below to calculate the number of boxes (b) he bought. 18b – 2 = 214

Answers

Answer: 18b-2+2=214 +2

Step-by-step explanation:Add 2 both sides of the equation

Answer:

b = 12; he bought 12 boxes.

Step-by-step explanation:

18b - 2 = 214 (subtract 2 on both sides)

18b = 216 ( divide 18 on both sides to get 'b' alone)

b = 12

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    1/3*(-x+3)-(-x-4)=0

Step by step solution :

STEP

:

           1

Simplify   —

           3

Equation at the end of step

:

 (— • (3 - x)) -  (-x - 4)  = 0

Equation at the end of step 2

 (3 - x)    

 ——————— -  (-x - 4)  = 0

:

Rewriting the whole as an Equivalent Fraction

3.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  3  as the denominator :

             -x - 4     (-x - 4) • 3

   -x - 4 =  ——————  =  ————————————

               1             3      

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

STEP

4

:

Pulling out like terms

4.1     Pull out like factors :

  -x - 4  =   -1 • (x + 4)

Adding fractions that have a common denominator :

4.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(3-x) - ((-x-4) • 3)     2x + 15

————————————————————  =  ———————

         3                  3  

Equation at the end of step

:

 2x + 15

 ———————  = 0

    3  

STEP

5

:

When a fraction equals zero :

5.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 2x+15

 ————— • 3 = 0 • 3

   3  

Now, on the left hand side, the  3  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  2x+15  = 0

Solving a Single Variable Equation:

5.2      Solve  :    2x+15 = 0

Subtract  15  from both sides of the equation :

                     2x = -15

Divide both sides of the equation by 2:

                    x = -15/2 = -7.500

One solution was found :

x = -15/2 = -7.500

Answer:

Graph B is the correct answer. Just in case it is not choice B for you, it's the graph with points (1,1), (2,2), (3,4), and (4,8) in that order. Sadly, the other guy is incorrect and you should not listen to him.

Step-by-step explanation:

The graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)

What is a geometric sequence?

A geometric sequence is a sequence that has a common ratio

The common ratio of a geometric sequence is calculated as:

[tex]r = \frac{y_2}{y_1}[/tex]

Using the above rule, we have:

[tex]r = \frac{2}{1} = \frac 42 = \frac 84[/tex]

[tex]r =2 =2 =2[/tex]

The above represents option B, and it has a common ratio of 2

Hence, the graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)
