Solve the equation, and check the solutions √(x+6)=3.

Mathematics
1 answer:
posledela3 years ago
8 0

Answer:

The solution is x = 3

Step-by-step explanation:

We have the following equation:

\sqrt{x+6} = 3

Elevating both sides to 2, we can isolate x

\sqrt{x+6}^{2} = 3^{2}

x + 6 = 9

x = 9 - 6

x = 3

Checking

\sqrt{x+6} = \sqrt{3+6} = \sqrt{9} = 3

prohojiy [21]

Answer:

60

Step-by-step explanation:

Sum the parts of the ratio, 5 + 9 + 13 = 27 parts

Divide the amount of concrete by 27 to find the value of one part of the ratio.

324 ÷ 27 = 12 ← value of 1 part of the ratio , thus

5 parts = 5 × 12 = 60 ← cement

9 parts = 9 × 12 = 108 ← sand

13 parts = 13 × 12 = 156 ← gravel
