Answer:

t = 12

Step-by-step explanation:

1. Because ∠(8t+1) and ∠97 are vertical angles, that means they're congruent.

2. To find t, we can write the equation: 8t + 1 = 97.

3. (Solving)

Step 1: Subtract 1 from both sides.

  • 8t + 1 - 1 = 97 - 1
  • 8t = 96

Step 2: Divide both sides by 8.

  • \frac{8t}{8} = \frac{96}{8}
  • t = 12

Therefore, t = 12.

Answer:

12

Step-by-step explanation:

this is very simple. since the angles are opposite the intersection of two lines, you know they must be equal.

therefore:

97 = 8t +1

solve for t:

t = 12

How many ways can 100 be written as the sum of distinct integers from the set {1, 2,..., 15}?
konstantin123 [22]

Answer:

48 ways

Step-by-step explanation:

Let me take a guess

S₁_₁₅ = (1+15)*7 + 8 = 120

There are 48 combinations of distinct digits from 1 to 15 to make 20

120-20=100

So every 20 has a corresponding 100

I wish I got it right, otherwise report it.

What is the value of C in the matrix equation below?
lara [203]

Given:

The matrix equation is:

\begin{bmatrix}-18&3&5\end{bmatrix}-C=\begin{bmatrix}-22&1&12\end{bmatrix}

To find:

The value of matrix C.

Solution:

Let A=\begin{bmatrix}-18&3&5\end{bmatrix},B=\begin{bmatrix}-22&1&12\end{bmatrix}. Then the given equation can be rewritten as

A-C=B

-C=B-A

C=-(B-A)

C=A-B

On substituting the values of the matrices, we get

C=\begin{bmatrix}-18&3&5\end{bmatrix}-\begin{bmatrix}-22&1&12\end{bmatrix}

C=\begin{bmatrix}-18-(-22)&3-1&5-12\end{bmatrix}

C=\begin{bmatrix}-18+22&2&-7\end{bmatrix}

C=\begin{bmatrix}-4&2&-7\end{bmatrix}

Therefore, the correct option is C.
