Simplify 7(x + 3). 7x + 3 7x + 10 7x + 21 x + 21

Answers

Answer 1
The answer is 7x+21
Explanation: you have to distribute 7into c and three. So you would multiply 7 by x (or 1x) and 7 times 1 is 7 so it would be 7x and then you would multiply 7 times 3 which is 21 and there are no like terms with 7x and 21 so it’s just 7x+21
Answer 2

Answer: 7x+21

Perform the indicated operation. 1 and 2/3 plus 5 and 3/8

Answers

Answer:

7  1/24

Step-by-step explanation:

1 2/3+5 3/8=?

first you need to find the least common multiple between 2/3 and 3/8.

the lcm would be 24, so 24 would be your new denominator for both fractions, but the numerators will change to how much you just multiplied each denominator by to get 24. 8x3 is 24, so you would multiply 3x3 to get the new numerator: 9. 3x8 is 24, so you multiply 2x8 to get the new numerator for that fraction:16.

so your new fractions are 1 16/24 + 5 9/24

now you add 16+9=25 (25/24, which becomes 1  1/24), so then you have another whole number: +1, and you add it to 5+1, so no it's 5+1+1=7

so the answer would be 7 1/24

The coordinates of point T are (0,2). The midpoint of ST is (7, -4). Find the coordinates of point S.

Answers

Answer: The coordinates of point S is (14,-10).

Step-by-step explanation:

Midpoint of line joining [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by :-

[tex](x,y)=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]

Given, The coordinates of point T are (0,2). The midpoint of ST is (7, -4).

Let (a,b) be the coordinates of point S.

Then,

[tex](7,-4)=(\dfrac{0+a}{2},\dfrac{2+b}{2})\\\\\Rightarrow\ 7=\dfrac{a}{2},\ \ \ -4=\dfrac{2+b}{2}\\\\\Rightarrow\ a=7\times 2= 14, \ \ 2+b= 2\times-4 =-8\\\\\Rightarrow\ a=14,\ \ \ 2+b=-8\\\\\Rightarrow\ a=14, \ b= -8-2=6--10\\\\\Rightarrow\ a=14,\ b=-10[/tex]

Hence, the coordinates of point S is (14,-10).

Charlie has a collection of books that he wishes to display in a narrow bookcase with shelves of width 56cm. The thickest books are no more than 16cm wide and, when placed side by side, the entire collection takes up 2.4m. Find, with justification, the minimum number of shelves required to guarantee that all of the books can be displayed in the bookcase.

Answers

Answer:

5 shelves

Step-by-step explanation:

Given the following :

Width of shelves = 56cm

Maximum thickness of books = 16cm

When placed side-by-side, the entire collection of books takes up 2.4m

Minimum number of shelves required to guarantee that all of the books can be displayed in the book case.

Entire book collection = 2.4m = (2.4 × 100) = 240cm

Width of shelf = 56cm

In other to guarantee that the bookshelf contains all the books, we can assume that the each book is of maximum width, 16cm

Hence, maximum number of books each shelf can hold with guarantee

Width of shelf / max. Width of book

= 56cm / 16cm = 3.5

Hence, a shelf can hold 3 books with full guarantee.

If books are all 16cm thick, then the number of books ;

240 cm / 16 cm = 15 books

If one shelf can hold 3 books, then,

15/3 = 5 shelves are required to hold the books with maximum guarantee.

Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x
determine the numerical length of MN

Answer : MN =

Answers

Answer:

MN = 4

Step-by-step explanation:

Given that L, M, N are collinear,

LN = 9,

MN = 4x

LM = 5x

Required:

Length of MN

SOLUTION:

To calculate the numerical length of MN, we need to find the value of x.

To find the value of x, generate an equation to solve for x as follows:

[tex] LM + MN = LN [/tex] (segment addition postulate)

[tex] 5x + 4x = 9 [/tex] (substitution)

Solve for x

[tex] 9x = 9 [/tex]

Divide both sides by 9

[tex] \frac{9x}{9} = \frac{9}{9} [/tex]

[tex] x = 1 [/tex]

MN = 4x

plug in the value of x

MN = 4(1) = 4

Muson
o
9:00

Answers

Answer:

total dogs= 2

total pets= 2+4+5=11

so, the ratio of dogs to all pets = 2/11

Step-by-step explanation:

Based on the number of all animals in the shop as well as the number of dogs, we can infer that the ratio of dogs to the others is 2 : 11

The first thing to do is to find the total number of animals in the shop:

= Dogs  + Cats + Hamsters

= 2 + 4 + 5

= 11 animals

The ratio of dogs to the rest of the animals is:

= Number of dogs : Number of animals

= 2                          :        11

= 2 : 11

In conclusion, the ratio is 2:11.

O Multiply a term by 2 and add 1 to get the next term

Answers

Answer:

multiply a term by 2 and add 1 to get the next term

Step-by-step explanation:

3×2=6 +1 =7

7×2=14+1= 15

15×2=30+1=31

Answer:

  Multiply a term by 2 and add 1 to get the next term

Step-by-step explanation:

The first differences of terms are ...

  7 -3 = 4

  15 -7 = 8

  31 -15 = 16

We notice that these increase by a factor of 2. This signifies an exponential sequence. That factor (2) will be the value that each term is multiplied by to get the next. This eliminates the choices "add 4" and "multiply a term by 3 ...".

Trying the remaining two choices, we find that the one that fits is the one shown above.

  3+7 ≠ 15, so "the sum of the two preceding terms" doesn't work

  2(3) +1 = 7; 2(7) +1 = 15; 2(15) +1 = 31, so "multiply by 2 and add 1" works fine

if angle LMPis 11 degrees more than angle NMP and angle NML is 137 find each measure.

Answers

Answer:

angle NMP = 63°

angle LMP = 74°

Step-by-step explanation:

Let angle NMP be x° . It's given that angle LMP is 11° more than angle NMP. So, angle LMP = x° + 11°

But angle NML = 137°.

So,

angle NMP + angle LMP = 137°

=> x° + x° + 11° = 137°

=> 2x° + 11° = 137°

=> 2x° = 137° - 11°

= 126°

=> x° = 126/2 = 63°

angle NMP = 63°

angle LMP = 63 + 11 = 74°

MIKA = 1 + π/2 = 1 + 22/7*½ = 1 + 22/14 = 1 + 1.6 = 2.6

JASON = 12/5 = 2⅖ = 2.4
