Solve for x<br> -3(x + 4) - 2 = -2(x - 5)<br> x= -4<br> x = -11/5<br> x = 24<br> x = -24
Gala2k [10]

-3 (x + 4) - 2 = -2 (x - 5)

-3x - 12 - 2 = -2x + 10

-3x + 2x = 10 + 12 + 2

-x = 24

x = -24

2. The \sqrt{54} is between 7 and 8.

3. The \sqrt{18} is between 4 and 5.

4. The \sqrt{99} is between 9 and 10.

5. The \sqrt{41} is between 6 and 7.

Step-by-step explanation:

1. \sqrt{10}: 10 is near the perfect squares 9 and 16, which would mean its answer is between their square roots which are 3 and 4.

2. \sqrt{54}: 10 is near the perfect squares 49 and 64, which would mean its answer is between their square roots which are 7 and 8.

3. \sqrt{18}: 10 is near the perfect squares 16 and 25, which would mean its answer is between their square roots which are 4 and 5.

4. \sqrt{99}: 10 is near the perfect squares 81 and 100, which would mean its answer is between their square roots which are 9 and 10.

5. \sqrt{41}: 10 is near the perfect squares 36 and 49, which would mean its answer is between their square roots which are 6 and 7.
