let the required number be x then

\begin{gathered} \frac{60}{x}\times100=40 \\ x=\frac{60}{40}\times100 \\ x=150 \end{gathered}

So 60 is 40% of 150.

If a person starts investing $100 per month starting at age 21, and that money earns a 5% return every year, how much will this
aalyn [17]

The formula for calculating compound interest with yearly contributions is:

Balance = X*(1 + Y)^n + Z((1 + Y)^(n + 1) - (1 + Y)/Y)

where the balance is the money earned after n years invested

Y is the interest rate as a fraction

Z is the yearly contribution

X is the starting investment

Therefore the calculation for this example is:

Balance = 1200*(1 + 0.05)^48 + 1200((1.05)^49 - (1.05)/05)

= $249,393.5

Solve the equation square root 2x – 7 + x = 5 algebraically, and justify the solution set
yarga [219]

Answer: x=4

Step-by-step explanation:

2x-7+x=5

Group like terms:

\left(2x+x\right)-7=5

Simplify the arithmetic:

3x-7=5

Add 7 to both sides:

3x-7+7=5+7

Simplify the arithmetic:

3x=5+7

Simplify the arithmetic:

3x=12

Divide both sides by 3:

\frac{3x}{3}=\frac{12}{3}

Simplify the fraction:

x=\frac{12}{3}

Find the greatest common factor of the numerator and denominator:

x=\frac{4\cdot 3}{1\cdot 3}

Factor out and cancel the greatest common factor and the answer will be:

x=4
