2x+4≤3(x+2)
Multiply numbers
8≤3(x+2) distribute 3 through the parenthesis
8 ≤ 3x +6
Move the variable to the left and change ints sign
8 - 3x ≤ 6
Move the constant to the right-hand side
And change its sign
-3x ≤ 6 - 8
Calculate the diffrences
-3x ≤ -2
Divide both sides of the inequiality by -3 and flip the inequality sign
X ≥ 2/3 - solution

The sum of two numbers is 10. twice the first number is 4 more than twice the second. what are the two numbers?
Ludmilka [50]
X+ y = 10
2x = 2y+4

2x/2 = 2/2y+4/2
x = y + 2

x+y = 10
y+2+y=10
2y + 2 = 10
2y +2-2 =10-2
2y = 8
2y/2 =8/2
y = 4

x + y =10
x + 4 =10
x +4-4 =10-4
x = 6

Check
2x = 2y +4
2(6) = 2(4) +4
12 = 8+4
12= 12

Mr. Fitch hires a landscape architect to renovate his front yard the rectangular yard is 30 feet long is the area of the front y
Vinil7 [7]

Answer:

The width of the yard is 20 ft

Step-by-step explanation:

In this particular question, we are asked to calculate the width of the rectangular front yard given the area of the front yard and the length of the front yard.

Mathematically, the area of the front yard is calculated by multiplying the length of the front yard by the breadth of the front yard.

Let’s say A = L * W

Substituting the known values, the unknown width would thus be:

W = A/L = 600 sq.ft / 30ft

W = 20 ft
