In 1846 the depth of the river was 2.5 feet deep. In 1847 it rose 9%. This year, 1848, it dropped 6%. How deep is the river now?
Virty [35]

Answer:

So the answer is 2.5615 feet.

Step-by-step explanation:

So the river is 2.5 feet deep, and when you find that 9% is, using the cross-multiplication formula to find the percent then 9% of 2.5 is 0.225, and when you add that to 2.5 you get 2.725, and when you find 6% of 2.725, you get 0.1635, and since it dropped, you subtract, and you end up with 2.5615

Hope I helped

Solve for x. 45(15x+20)−7x=56(12x−24)+6
Nady [450]

Answer:

The value of the equation for x is x=\frac{1119}{2} or 559.5.

Step-by-step explanation:

Consider the provided equation.

45(15x+20)-7x=56(12x-24)+6

We need to solve the equation for x.

Use the distributive property: a(b+c)=ab+ac

45(15x+20)-7x=56(12x-24)+6

675x+900-7x=672x-1344+6

Add the like terms.

668x+900=672x-1338

Isolate the variable as shown:

672x-668x=900+1338

4x=2238

x=\frac{2238}{4}

x=\frac{1119}{2}

Hence, the value of the equation for x is x=\frac{1119}{2} or 559.5.
