Select one point and move it over 8 points to the left, then reflect across x axis would give u the congruent shape
answer: c
All the correct answers of the equations using order of operations are;
B. 8⋅7 ÷ 2 − 12 = 22 − 2⋅3
C. 48 ÷ 8 + 2³ = 5 + 3²
<h3>How to use order of operations?</h3>
The rule used for order of operations is PEMDAS and it states that the order of operation starts with the calculation enclosed in brackets or the parentheses first. Exponents (degrees or square roots) are then operated on, followed by multiplication and division operations, and then addition and subtraction.
Using the PEMDAS rule, the solutions would be as follows:
A. 9² − 7² = 20 ÷ (7 − 2)
81 - 49 = 20 ÷ 5
32 = 4
Thus, this is not true.
B. 8⋅7 ÷ 2 − 12 = 22 − 2⋅3
56 ÷ 2 − 12 = 22 - 6
28 - 12 = 16
16 = 16
Thus, this is true.
C. 48 ÷ 8 + 2³ = 5 + 3²
6 + 2³ = 5 + 9
6 + 8 = 14
14 = 14
Thus, this is true.
D. 150 ÷ 5² = 30 − 4² − 12
150 ÷ 25 = 30 − 16 − 12
6 = 30 - 28
6 = 2
Thus, this is not true.

Answer:
248
Step-by-step explanation:
A + B = 180 -EQ 1
A + C =180 -EQ 2
B =124
BY EQ1 :
A = 180 - 124 =56
C = 180 -56 =124
B + C = 124+124
=248
Answer:
2:3
Step-by-step explanation:
A total of 30 students with 12 girls so its 12/30 & its the balance of 18 boys or 18/30
12:18 ÷ by 2 on both sides is.6:9 & 2:3, Answer is Ratio of 2:3.
