The answer is B. 12,34 cm .....:)
The answer for your question is c
Facts:
MR Price takes his wife + two children
The price of adult's ticket is 2 times higher that child's
They paid $12.6 in total
Answer:
X is the price of child's ticket so equation will look:
2x (fathers' ticket) + 2x (mother's ticket) + x (first child) + x (second child) = $12.6 (total price)
6x = 12.6
X = 2.1
Child's ticket costs $2.1
Answer:
2.5+2.0+4.0+3.0 =11.5 if I'm not mistaken
Answer:
No, Angela is not correct.
As the method Jim was performing will also lead to the solution.
Step-by-step explanation:
We are given first equation as:
Ax + By = C
Second equation is:
Dx + Ey = F
Jim solved the equation as:
He begins by multiplying equation (1) by D and equation (2) by A.
and so by subtracting both the equations he will obtain a value of y.
and then put the y-value in any of the given two equations to obtain the value of x.
Angela Method:
you should have multiplied equation (1) by E and equation (2) by B.
and when she will subtract both the equations she will get the value of x first and then when she will put the value of x in any of the given equation she will obtain the value of y.
But both will get a value for x and y.
Hence, the method Jim was performing was also correct.
