Solving a One-Variable Linear Equation

Mathematics
1 answer:
vitfil [10]2 years ago
5 0

Answer:

\Longrightarrow:\boxed{\sf{h=14}}

Step-by-step explanation:

Isolate the term of h from one side of the equation.

Use the distributive property.

<u>Distributive property:</u>

→ A(B+C)=AB+AC

<h3>7h-5(3h-8)=-72</h3>

<u>First, multiply expand.</u>

⇒ -5(3h-8)

⇒ -5*3h=-15h

⇒ -5*8=40

<u>Rewrite the problem.</u>

→ -15h+40

⇒ 7h-15h+40=-72

⇒ 7h-15h=-8h

→ -8h+40=-72

<u>Subtract by 40 from both sides.</u>

⇒ -8h+40-40=-72-40

<u>Solve.</u>

⇒ -72-40=-112

⇒ -8h=-112

<u>Then, you divide by -8 from both sides.</u>

⇒ -8h/-8=-112/-8

<u>Solve.</u>

<u>Divide the numbers from left to right.</u>

→ -112/-8=14

\Longrightarrow: \boxed{\sf{h=14}}

  • <u>Therefore, the correct answer is h=14.</u>

I hope this helps! Let me know if you have any questions.

A 6 cm long spring extends to 9 cm when a 1 kg load is suspended from it. What would be its length if a 2 kg load were suspended
vampirchik [111]

Answer:

12 cm

Step-by-step explanation:

To calculate the length of a spring with a 2 kg load, compare the displacement of a 1 kg load and adjust accordingly.

When a 1 kg load is suspended from the spring, the spring which is 6 cm stretches to 9 cm. This is 3 cm longer due to the weight. If you attach a weight which is twice as much then the displacement will be twice as much. Instead of stretching an additional 3 cm, it will stretch 2*3 = 6 cm. Add this to the length of the spring and it stretches in total 6 + 6 = 12 cm.

Work out the percentage change when a price of £10 is increased to £12.
Anastaziya [24]

Answer:

20%

Step-by-step explanation:

Use the percent change formula: difference = % * original cost

12 - 10 = 2

The difference is 2 and the original cost is 10. Now, we have the equation

2 = % * 10. We don’t know the percentage right? So now we have to find the percentage. To do this, you will have to do 2 divided by 10, which is 0.20. Lastly, we have to turn 0.20 into a percentage by multiplying it by 100, leaving you with 20%. So therefore, 20% is the percent increase. Hope this helps!
