• Add 9 to both sides to isolate $\triangle$.

Now, let's carry out these steps:

Starting with the equation $\triangle - 9 = 20$.

To solve the equation $\triangle - 3 = 70$, we will use basic algebra to isolate the value of $\triangle$.

We start by adding 3 to both sides of the equation to isolate $\triangle$:

$\triangle - 3 + 3 = 70 + 3$

Notice that $-3 + 3$ on the left side simplifies to 0, which leaves us with:

$\triangle = 70 + 3$

Now, perform the arithmetic on the right side:

$\triangle = 73$

Hence, the numerical value of the triangle is $73$.

The problem involves solving a simple algebraic equation:

$\triangle - 7 = 80$

• Step 1: To solve for $\triangle$, we need to isolate it on one side of the equation. We can do this by adding 7 to both sides of the equation to reverse the subtraction.

$\triangle - 7 + 7 = 80 + 7$

This simplifies to:

$\triangle = 87$

The value of the triangle symbol $\triangle$ is $87$.

Therefore, the solution to the problem is $\triangle = 87$, which corresponds to choice 4 in the provided list of answer choices.

To solve this problem, we'll perform a direct replacement and subtraction. Here are the steps:

• Step 1: Replace $\circ$ with its given value. We know that $\circ = 8$, so we substitute to get $57 - 8$.
• Step 2: Perform the subtraction operation. We need to compute $57 - 8$.

Starting from the rightmost digit of the two numbers involved, we need to subtract 8 from 57:

• First, look at the units digit: Since 7 is greater than 8, let's subtract directly: $7 - 8$ cannot be done directly as we need to regroup.
• We regroup by borrowing 1 ten from the tens place in 57. This turns the 5 in the tens place into a 4, and the 7 in the units place into 17.
• Now subtract the single digits: $17 - 8 = 9$.
• Finally, subtract the tens digits: $4 - 0 = 4$.

As a result, $57 - 8 = 49$.

This solution corresponds to choice 1: $49$.

Therefore, the solution to the problem is $49$.
