The sum of three number is -44.85. One of the numbers is 24.6. The other two number are equal to each other. What is the value o

tiny-mole [99]

Let the number be x. The other number is also x.

Given the first number is 24.6 and sum is -44.85
24.6 + x + x = -44.85

Combine like terms:
2x + 24.6 = -44.85

Add 24.6 on both sides:
2x = -44.85 - 24.6

Evaluate Right Hand Side:
2x = -69.45

Divide both sides by 2:
x =- 34.725

Answer: The two numbers are both -34.725.

The sum of two numbers is -6. The difference is 16. Find the two numbers.

Bess [88]

Answer:

$-5\:\mathrm{and}\: 11$

Step-by-step explanation:

We can write the following system of equations:

$\begin{cases}x+y=6\\x-y=16\\\end{cases}$

Adding both equations together, we isolate $x$ and get:

$2x=22,\: x=11$

Plugging $x=11$ in any of the equations, we can solve for $y$ :

$11+y=6,\: y=-5$

Verify that the solution pair $(11, -5)$ works $\checkmark$

Therefore, the two numbers are $\fbox{$-5\:\mathrm{and}\: 11$}$ .

If T is the midpoint of SU find the values of x, ST and SU.

Nitella [24]

Answer: The required values are

x = 12 units, ST = 60 units and SU = 120 units.

Step-by-step explanation: Given that T is the midpoint of SU, where

ST = 5x and TU = 3x + 24.

We are to find the values of x, ST and SU.

Since T is the midpoint of SU, so we get

$ST=TU\\\\\Rightarrow 5x=3x+24\\\\\Rightarrow 5x-3x=24\\\\\Rightarrow 2x=24\\\\\Rightarrow x=\dfrac{24}{2}\\\\\Rightarrow x=12.$

So, the value of x is 12.

Therefore,

$ST=5\times12=60$

and

$SU=5x+3x+24=8x+24=8\times12+24=96+24=120.$

Thus, the required values are

x = 12 units, ST = 60 units and SU = 120 units.
