B) 6 years old
C) 8 years old
D) 10 years old
Answer:
The answer is B) 6 years
Step-by-step explanation:
First of all, build an equation. With the given problem, you can come up with:
s + c = 16
In which interprets that both their ages summed up are 16. Secondly,:
s = c + 4
After you will use the typical system of equations to solve. So, plug in the second equation to the first, where s will become c + 4, and the equation is now:
c + 4 + c = 16
And finally, solve for Charmaine's age.
2c + 4 = 16
-4 -4
-----------------
2c = 12
c = 6
Answer:6 years old
Step-by-step explanation:
The two consecutive integers that the sum is 149 are 74 and 75.
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the number is 149. The two consecutive integers can be calculated as below,
Suppose the two consecutive integers are x and ( x + 1 ).
x + ( x + 1 ) = 149
2x + 1 = 149
2x = 148
x = 148 / 2
x = 74
The second integer would be,
x + 1 = 74 + 1 = 75

angle HDG = angle HFE
==========================================================
Explanation:
We have the statement given to us. Note that "H" is in the middle for both sequences of three letters. For DHG, start at H and move back one space to get to D. Move back another unit to wrap around to G. So the new sequence is HDG which forms the first angle.
Follow the same pattern but for FHE now. Start at H, move backward one spot to F, then move back again to wrap around to E. We have HFE
This shows angle HDG pairs up with angle HFE. The corresponding angles are congruent due to CPCTC
CPCTC = corresponding parts of congruent triangles are congruent
Notice how angles HDG and HFE are alternate interior angles, which lead to showing DG is parallel to EF.
