I need help with this ​

Answer:

30 meters

Step-by-step explanation:

Perimeter smaller rectangle: 2(x+1)+2x = 2x+2+2x

= 4x+2

Perimeter larger rectangle: 2(4x-5)+2(3x-1) = 8x-10+6x-2

= 14x -12

2(4x+2)+2 = 14x-12

8x+4+2 = 14x - 12

8x + 6 = 14x - 12

6 + 12 = 14x - 8x

18 = 6x

x = 3

14*3-12 = 30 meters

Step-by-step explanation:

x = the area in black

each triangle have area = 80

the area of the 3 triangles without combining them = 80 × 3 = 240

the total area = 210

the total area in the figure = 3 triangles area - 2x

because we have calculated 1 black area not the three of them so we need to add its area once and get rid of the others by subtracting them from the sum of the 3 triangles area

240 - 2x = 210

2x = 30

x = 15

hope that helps

Answer:

x=-1

Step-by-step explanation:

1/2x +1/2=x+1

Subtract 1/2x from each side

1/2x-1/2x +1/2=x-1/2x+1

1/2 = 1/2x +1

Subtract 1 from each side

1/2 -1 = 1/2x +1-1

-1/2 = 1/2x

Multiply each side by 2

2 * (-1/2) = 1/2 x*2

-1 =x

Answer:

7/30

Step-by-step explanation:

5/6-3/5 ,the LCM of denominators 6 and 5 is 30 ,6 denominator divided by 30 the result from the LCM times 5 the numerator is =25, 5 denominator divided by 30 the result from the LCM times 3 is =18 ,then subtract 25 from 18 giving you 7 ,then 7/6 or seven divided by six is one whole number, one over six

Step-by-step explanation:

Answer:

7(10−[tex]2^{3}[/tex])+ [tex]\frac{8}{2}[/tex]

=18

Step-by-step explanation:

7(10−[tex]2^{3}[/tex])+[tex]\frac{8}{2}[/tex]

=7(10−8)+ [tex]\frac{8}{2}[/tex]  

=(7)(2)+[tex]\frac{8}{2}[/tex]  

=14+[tex]\frac{8}{2}[/tex]  

=14+4

=18

Answer:

20.51282

Step-by-step explanation:

1. Starting by the smallest number that can be divided. 80÷39 equals to 2.

2. Now we write 2 in the answer line.

3. Multiply the result by 39. That makes us 78.

4. Now we write 78 under 800.

5. Subtract the numbers (80-78) and now we have 2.

6. Bring 0 next to our substracted number (2) so that will make it 20.

7. Divide the subtracted number with our initial value (39). That will make us a decimal number (0.512) but we will note the 0 except if you want to make it detailed then note 20.51282

8. Add the 0 next to the 2 that we writed in the start above.

9. Write the remainder (20) next to the quotient.

10. The result is 20 or to be exact 20.51282 and we have a remainder of 20.

Answer:

90.

Step-by-step explanation:

7m - 3 = 53

m would be 8 because 56 - 3 = 53.

11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.

Answer:

x = c/(a-b)

Step-by-step explanation:

Answer:

No I am pretty sure it is the 4th answer my guy.

Step-by-step explanation:

2/3x-10=21

There is an angle of 90 degrees given between the two lines.

When 2 lines are at a 90 degree angle from each other they are perpendicular.

Answer: A. Perpendicular

Answer:

Every integer is a rational number. The statement is true. An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

For example, lets use the integer, -5.

If it was rational number it would need to be either a decimal or fraction.

So -5 is not a rational number and is an integer.

If the number was 0.5 or 1/5, the number would have been rational.

Inconclusion your statement is true.

Explanation:

To find the hourly rate, we divide the money made over the number of hours.

Then we'll multiply each of these results by 10 to figure out how much they made over the 10 hours

We see that Zainab made more money and she made 55-52.5 = 2.50 dollars more.
