An inequality can be formed by simply translating the problem statement to numerical expressions.

From the problem we know that 3w added with 52 hours should be equal or greater than 90 (helpful insight from the keyword "at least"). Therefore, it's inequality would look like:

3w+52>=90 (>= is used instead of ≥ for constraints in formatting)

The inequality above best models the situation.

Answer: 13 weeks.

Step-by-step explanation:

Every number seems to be tripled:

we have that:

Antonia needs to have worked at least 90 volunteer hours.

She already has worked 52 hours over the summer

She needs to work 3 hours per week to complete her remainder, we want to find how many weeks she needs to work.

the hours that she needs to work are:

90 - 52 = 38

she needs to work 38 hours, then, at a rate of 3 hours per week we have that:

w = 38/3 = 12.67

but we need to round up this, so we would have 13 weeks.

and she will work a total of 3*13 = 39 hours, plus the 52 that she already had this ad to 91 hours, so she will complete the minimum of 90 hours.

A triangle has sides xcm, (x + 4) cm and 11cm, where x is a whole number of cm. if the perimeter of the triangle is less than 32
NARA [144]

9514 1404 393

Answer:

  {4, 5, 6, 7, 8}

Step-by-step explanation:

The inequality related to the perimeter is ...

  x +(x +4) +11 < 32

  2x < 17 . . . . . . . . . . . . subtract 15

  x < 8.5

The inequality related to the triangle inequality is ...

  (x) +(x +4) > 11

  2x > 7

  x > 3.5

Then possible whole-number values of x are ...

  {4, 5, 6, 7, 8}

Drag the tiles to the correct boxes to complete the pairs.
solong [7]

Answer:

1. Number line 2

2. Number line 1

3. Number line 4

4. Number line 3

Step-by-step explanation:

1. x – 99 ≤ -104

Solving by adding +99 on both sides

x - 99 +99 ≤ -104 +99

x ≤ -5

Number line 2 represent x ≤ -5

2. x – 51 ≤ -43

Adding +51 on both sides

x -51 +51  ≤ -43 +51

x ≤ 8

Number line 1 represent x ≤ 8

3. 150 + x ≤ 144

Adding -150 on both sides

150 + x -150 ≤ 144 -150

x ≤ -6

Number line 4 represent x ≤ -6

4. 75 < 69 – x

Adding +x on both sides

75 + x < 69 -x +x

x < 69 -75

x < -6

Number line 3 represent x < -6
