What is answer 6x+7-5x=10

2 answers:

8 0

X = 3, this is the correct answer because first if you start with combining like terms you would combine the 6x and -5x which would result in X.

Second, your equation bring X+7=10 you then subtract 7 from both sides and the equation that results is X=3.

(3x+4)^3=2197 solve this equation

Burka [1]

(3x + 4)³ = 2197

Taking the cube root in this case is easier, although we can do it the extended way which is complicated.

$\sqrt[3]{(3x+4)^3}$ = $\sqrt[3]{2197}$
3x + 4 = 13

Now solve normally.

subtract 4
3x + 4 = 13
-4 -4

3x = 9
Divide by 3 to isolate 3

$\frac{3x}{3} = \frac{9}{3}$
3 and 3 cancels out

x = 3

Ethan borrowed $2,190 for a new dirt bike. He will pay the money back in 3 years with a simple interest rate of 2.5%. How much i

Taya2010 [7]

Answer:

<h2>The interest ethan will pay is $164.25</h2>

Step-by-step explanation:

To calculate the interest paid by ethan on the borrowed bike using the formula.

Simple Interest = Principal * rate * time/100

Principal = $2,190, rate = 2.5%, time = 3years

On substitution

SI = $\frac{2190*3*2.5}{100}$

$SI = \frac{16,425}{100}\\ SI= $164.25$

The interest ethan will pay is $164.25
