Answer:

- 34

Step-by-step explanation:

Let the required number be x

Therefore, one less than a number = x - 1

(x - 1) \div 5 =  - 7 \\  \\  \frac{x - 1}{5}  =  - 7 \\ \\  x - 1 =  - 7 \times 5 \\  \\ x - 1 =  - 35 \\  \\ x = 1 - 35 \\  \\ x =  - 34

= -4⁹ײ

= -4¹⁸

=( -4)¹⁸

  • (4-³)-³

= 4-³ × -³

= 4⁹

  • (4⁶)-³

= 4⁶ × -³

= 4-¹⁸

= 1/4¹⁸

Which of the following is the solution for 7 - 4x ≥ 35 ?
melamori03 [73]
There are no solutuons listed (says which of the following). My answer below should be in the list to choose from.

7 - 4x ≥ 35
subtract 7 from both sides

-4x ≥ 28
divide both sides by -4 AND change the direction of the inequality sign because we're dividing by a negative

x ≤ -7

CHECK:
7 - 4x ≥ 35
7 - 4(-7) ≥ 35
7 + 28 ≥ 35
35 ≥ 35

ANSWER: x ≤ -7

Hope this helps! :)

Answer:

5,811.95\  m^2 of fabric.

Step-by-step explanation:

-The amount of fabric needed is equivalent to the  area of the two gardens.

-We calculate the combined areas as:

A=A_s+A_b\\\\=\pi r^2+\pi R^2\\\\=\pi(25^2+35^2)\\\\=1850\pi \ m^2\\\\=5811.95\ m^2

Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.
