What value can be written on the blank line to make the expressions equivalent
Gala2k [10]
<span>The expression is missing from the question, but here is the given expression which I got from a similar question.

48 + 54 = ___ ´ (8 + 9)

Theleft-hand side of the equation is:
                                                             48 + 54 = 102
Now the right-hand side of the equation:
                                                                    A </span>× (8+9) = Right-hand side
                                                                    A × (8+9) = 102
Solving for the unknown variable A,
                                                                    A × 17 = 102
Dividing by 17 on both sides,
                                                A × 17 ÷ 17 = 102 ÷ 17
                                                         A × 1 = 6
                                                              A = 6

Hence,
           48 + 54 = 6 x (8 + 9)

Ket [755]

Answer:

2

Step-by-step explanation:

(x + 6) - (3x - 6)               Remove the brackets.

x + 6 - 3x + 6                 Collect like terms

Difference in points = 12 - 2x

If x = 5 then

Difference in points = 12 - 2*5

Difference in points = 12 - 10

Difference in points = 2

Write the sum using summation notation, assuming the suggested pattern continues. 8 - 40 + 200 - 1000 + ...
mr_godi [17]
Each successive term is -5 times the previous one, so the underlying sequence is

a_n=-5a_{n-1}=(-5)^2a_{n-2}=(-5)^3a_{n-3}=\cdots=(-5)^{n-1}a_1=8(-5)^{n-1}

The sum can then be written as

8-40+200-1000+\cdots=\displaystyle\sum_{n=1}^\infty8(-5)^{n-1}

Short answer <2 and <3

Explanation
<4 is an interior angle. It has a supplementary angle in <1 which is the easiest to see. It also has another angle that is equal to it in number <5. <1 = <5 because they are vertically opposite angles. But the one that easier to see is <1.

That being said, the remote interior angles are the two interior angles that are not directly connected to <1. That is the remote part. Interior angles are those that are inside the triangle. That can only be <2 and <3.

The answer is <2 and <3 <<<< answer
