The answer for "-2a + 3b" is 5.
To solve this equation, you must first find "a" and "b". A^3 times B^2 = 72. In this case, a = 2 (2*2*2 = 8) and b = 3 (3*3 = 9) since their outcomes multiplied together equal 72.
Now you fill in for "a" and "b". "-2*2 + 3*3" before adding you do all the multiplying, which leaves "-4 + 9". Combining like terms gives you 5.
I hope this helps!!
Answer:
(7, 0) and (3,0)
Step-by-step explanation:
On the graph, the parabola crosses the x-axis at two points. The two points are called the roots. And since they cross at (7, 0) and (3, 0), they are our roots. Hope this helps!
Answer:
50
Step-by-step explanation:
The translation of the question is as shown;
First note that the original number is 35
The sum of 35 and one-fifth part of itself .
= 35 + 1/5(35)
= 35+7
= 42 ... A
sum of one-seventh part of itself and 3 will be;
= 1/7(35) + 3
= 5+3
= 8... B
Adding A and B together wiill give us the final result
A+B = 42+8
A+B = 50
The sum of 35 and one-fifth part of itself added to the sum of one-seventh
part of itself and 3 is therefore equivalent to 50
Answer:
Cost of an adult ticket is £10.75
Step-by-step explanation:
Given:-
Cost of 1 adult ticket is £6 more that the cost of a child ticket.
Total cost of 6 tickets = £40.50
c is cost of a child ticket and a is the cost of an adult ticket.
To find:- Cost of 1 adult ticket =?
Solution:-
For 2 adults and 4 children, and the total cost of tickets is £40.5, we get the following equation,
-----------------(1)
As the Cost of 1 adult ticket is £6 more than the cost of a child ticket, we can the following equation,
-----------------(2)
Now, substituting the value of a from equation 2 in equation 1 we get,
--------------------(3)
Now substituting the value of c from equation 3 in equation 2,
As a is the cost of 1 adult ticket,
Therefore Cost of an adult ticket is £10.75
Answer:
D
Step-by-step explanation:
X < -1 means "X could be anything less than -1."
However, the number line only has selected the numbers greater than 1. That is why it does not represent the equation. Hope this helps :)
