Answer:
53.2 kg
Step-by-step explanation:
Let E represent Esther's weight. Then Henry's weight is E/2, and David's weight is E-5.2. Their average weight is ...
((E-5.2) + E + (E/2))/3 = 42.6
2.5E -5.2 = 127.8 . . . . . . . . . . multiply by 3, simplify
2.5E = 133 . . . . . . . . . . . . . . . . add 5.2
E = 133/2.5 = 53.2 . . . . kg
Esther's weight is 53.2 kg.
Answer:
up 10
Step-by-step explanation:
The function would change from
C(x) = 0.3x + 40
to
C(x) = 0.3x + 50
The change is only to the y-intercept, so the graph of the function will move up 10.
Answer:
37
Step-by-step explanation:
The calculation of size for a new television is shown below:-
With the help of Pythagoras theorem
where
h indicates hypotenuse which is the diagonal length
b indicates the base which is the length of the horizontal side
p indicates perpendicular which is the TV length of the vertical side.
now, we will put the values into the above formula
Which gives result
= 36.7
or
= 37
First simplify 3x + 12 - 6x to -3x - 12
Next subtract 12 from both sides
Next subtract -9 - 12 and that would be -21
Next divide both sides by -3
Next lets simplify the fraction -21/-3 into 21/3 since those two negatives make a positive.
Lastly simplify the fraction 21/3 to get the answer.
Answer: x ≥ 7
Opposite angles are supplementary, the sum is 180 degrees.
6x+10+81.5=180
Combine like terms:
6x+91.5=180
Subtract 91.5 to both sides:
6x=88.5
Divide 6 to both sides:
x=14.75
The answer is 1) 14.75
Hope this helped!
