Find the three highest whole numbers that satisfy 2(3x+1)⩽ 1/2(2x-5).

-1, -2 ,-3

Step-by-step explanation:

2(3x+1)⩽ 1/2(2x-5)

Distribute

6x+2 ⩽ x-5/2

Subtract x from each side

6x-x +2 ⩽ x-x-5/2

5x +2 ⩽ -5/2

Subtract 2 from each side

5x+2-2 ⩽ -5/2 -2

5x ⩽ -5/2 -4/2

5x ⩽ -9/2

Divide each side by 5

5x/5 ⩽ -9/2 /5

x ⩽ -9/10

The largest whole numbers that satisfy

-1, -2 ,-3

-1, -2 and -3

Step-by-step explanation:

2(3x + 1) ⩽  (1/2)(2x - 5)

Open up Parentheses

6x + 2 ⩽  x - (2.5)

Isolate Variable

5x ⩽  -4.5

x ⩽  -.9

The 3 highest whole numbers ⩽  -.9 are -1, -2, and -3

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
