Answer:

D. x = 10, m<TRS = 60

Step-by-step explanation:

1. Approach

To solve this problem, one will set up an equation to model the problem. The problem gives that the sum of two angles (m<QRT and m<TRS) equals the third angle (m<QRS). Additionally, the measure of one of the angles is given (m<QRS = 122), and the expression for the values of the other two angles are given, (m<QRT = 7x - 8), (m<TRS = 6x). One can form an equation, and solve it to find the unknown. Finally, one can then substitute the values of the unknown, into the expression to find the measure of the angle.

2. Solve for (x)

One can set up an equation based on the given information, then solve the equation.

m<QRT + m<TRS = m<QRS

Substitute,

(7x - 8) + (6x) = 122

Simplify

7x - 8 + 6x = 122

13x - 8 = 122

Inverse operations

13x - 8 = 122

      +8    +8

13x = 130

/13      /13

x = 10

3. Find (m<TRS)

Now that one has the value of (x), one can substitute the value into the given expression for the (m<TRS), and solve to find the value.

m<TRS = 6x

x = 10

m<TRS = 6(10)

m<TRS = 60

An estate of $613,000 is left to three siblings. The eldest receives 2 times as much as the youngest. The middle sibling receive
Assoli18 [71]

Answer:

Eldest: $298500

Middle: $165250

Youngest: $149250

Explanation:

We can show the siblings like this:

e=2y                  (eldest)

m=16000+y       (middle)

To find the value of y, or the youngest sibling, we use an equation.

2y+16000+y+y=613000

Simplify:

4y+16000=613000

Subtract 16000 on both sides:

4y=597000

Divide both sides by 4:

y=149250

The youngest received $149250.

Knowing this, we can plug in the numbers into the original formulas:

e=2(149250)=298500                 ...or $298500

m=16000+149250=165250         ...or $165250

y=149250                                      ...or $149250

Add all those numbers up, and you reach $613000.
