What is the value of x?

Answer:

8, 10, 5

Step-by-step explanation:

7+8=15, 7+10=17, 7+5=12. You’re basically substituting the numbers in for n and seeing if its greater than or equal to 12.

Answer:

a) length = 3 and width = 6

Area of the rectangle = 3 × 6 = 18 cm²

b)  length = 7 and width = 2

Area of the rectangle = 7 × 2 = 14 cm²

c)  length = 5 and width = 4

Area of the rectangle = 5× 4 = 20 cm²

Step-by-step explanation:

Step(i):-

Given perimeter of the paper = 18 cm

we know that the paper has a rectangle shape

The perimeter of the rectangle = 18 cm

 2( l + w ) = 18

a)

we choose length = 3 and width = 6

The perimeter of the rectangle = 2( 3+6) = 18 cm

Area of the rectangle = 3 × 6 = 18 cm²

b)

we choose length = 7 and width = 2

The perimeter of the rectangle = 2( 7+2) = 18 cm

Area of the rectangle = 7 × 2 = 14 cm²

c)

we choose length = 5 and width = 4

The perimeter of the rectangle = 2( 5+4) = 18 cm

Area of the rectangle = 5× 4 = 20 cm²

Answer:

yards.

Step-by-step explanation:

Please find the attachment.  

We have been given that Marisela cut four equivalent lengths of ribbon. Each was 5 eighths of a yard long.    

To find yards of ribbon cut by Marisela, we will multiply 4 by 5 eighths of a yard (5/8).

Express answer as the sum of whole number and the remaining fractional units:

Therefore, Marisela cut  yards of ribbon.

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Just take the larger exponent and subtract the smaller exponent and it becomes --> [tex]\frac{1}{2^{2}}[/tex]

[tex]\frac{1}{2^{2}}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:  \frac{2}{5}  ; or, write in decimal form:  0.4 .

Step-by-step explanation:

Rewrite as:

_______________________

    [tex]\frac{4x}{7} = \frac{8}{35}[/tex] ;

________________________

Now, "Cross-factor multiply":

that is:

_____________________

 → Given:   [tex]\frac{a}{b} =\frac{c}{d}[/tex]  ;

    → ad = bc ;  (b≠0 ; d≠0) ;

_____________________

As such:

 4x * 35 = 7 * 8 ;

_______________________

We can divide one side of the equatiuon by "4" ; and one side by "7" :

  [tex]\frac{4x*35}{4*7} = \frac{7*8}{4*7}[/tex] ;

_______________________

We can simplify the "left-hand side":

 "4/4 = 1 " ; and "35/7 = 5 " ; & we are left with "x * 5" ; or "5x " .

________________________

We can simplify the "right-hand side":

 "7/7 = 1 " ; and: "8/4 =2 " ; to get: "2/1" ; which equals "2".

_________________________

So; we have:  " 5x = 2 " ; Solve for "x" ;

__________________________

  Divide each side of the equation by "5" ; to isolate "x" on one ide of the equation; & to solve for: "x" ;

__________________________

  " 5x/5 = 2/5 " ;  We cancel out the "5x/5" to "1x"; which equals "x":

    → x = [tex]\frac{2}{5}[/tex]  ;  or, write in decimal format:  "x = 0.4" ;

___________________________

\frac{2}{5}

Answer:

[tex]x = 0.4[/tex]

Step-by-step explanation:

[tex]\frac{7}{4} x \frac{4}{7} = \frac{7}{4} x \frac{8}{35}[/tex]

Reduce the number with the greatest common factor 7

[tex]\frac{1}{4} x 4x= \frac{7}{4}x\frac{8}{35}[/tex]

[tex]x=\frac{7}{4}x\frac{8}{35}[/tex]

[tex]x=7x\frac{2}{35}[/tex]

[tex]x=\frac{2}{5}[/tex]

X=1    Y=0

Y-12X+15+3X^2-16X+13-Y=3X^2

-12X+15-16X+13=0

-28X+28=0

X=1

Y=3-16+13=0

C 15

Step-by-step explanation:

20÷4x3=15

Answer:

C. 15

Step-by-step explanation:

If B's side length is 20, that means in the ratio 3:4 the 4 represents B's side length.

Multiply both sides of the ratio by 5:

15: 20

The answer is 15.

Answer:

C. 452.16 cm2

Step-by-step explanation:

A= π r^2 = π · 12^2 ≈ 452.38934 or 452.38

The closest answer to that listed is C

formula:(A = π r²)

π = 3.14

r(radius)^2= radius to the second power.

Answer:

288

Step-by-step explanation:

1. Use the formula: P*T=N

P = percent, T = Total, and N is the other number.

2. So, P*T=N, therefore, 25%*T=72

3. Simplify .25*T=72

4. So get the Total (T) by itself, you have to divide both sides by .25

5. T = 72/.25

6. 288

Step-by-step explanation:

RU intersect the angle

answer:

yes, because they have a common difference and it makes sense. in order to determine if this is a function, you would have to find their difference for each column. the x column has a difference of 2 for all. similarily, the y column has a difference of 2 for all. therefore, it is a function.

Answer:

x =-7. .y=6

Step-by-step explanation:

3x + 2y = -9

(X – Y = -13)×3

3x + 2y = -9

3x – 3y = -39

5y = 30

y=6

3x +2(6)=-9

3x=-21

x=-7
