A woman earns $ 1,350 in interest from two accounts in one year. If she has three times as much invested at 7% as she does at 6%

VashaNatasha [74]

Answer:

The woman invested $15,000 at 7% interest rate and $5,000 at 6% interest rate.

Step-by-step explanation:

We are given the following in the question:

Let x be the interest earned from 7% interest rate and y be the interest earned from 6% interest rate.

The woman invested has three times as much invested at 7% as she does at 6%.

Thus, we can write the equation:

$x = 3y$

The total interest is $1,350.

Thus, we can write the equation:

$1350 = \dfrac{7x}{100} + \dfrac{6y}{100}\\\\7x + 6y = 135000$

Solving the two equations by substitution method:

$7(3y) + 6y = 135000\\27y = 135000\\y = 5000\\x = 3(5000) = 15000$

Thus, she invested $15,000 at 7% interest rate and $5,000 at 6% interest rate.

Convert into like fractions -->
1/3 = 7/21 4/7 = 12/21
7+12 = 19
19/21 is spent therefore he has 2/21 left

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:

$x=4$
