Answer:8 and 4. Explanation: Let the 2 numbers be x and y with x > y. ⇒x+y=12→(1)←sum of 2 numbers. ⇒x−y=4→(2)← difference of numbers.
Step-by-step explanation: Let the 2 numbers be x and y with x > y. ⇒x+y=12→(1)←sum of 2 numbers. ⇒x−y=4→(2)← difference of numbers.
Answer:
x + 4
Step-by-step explanation:
Area of rectangle= length × breadth
In this question, one length is 5x + 3 and the area is 5x^2 + 23x + 12
This means that;
5x2 + 23x + 12 = 5x + 3 (b)
Hence, to get the other length (b) = 5x2 + 23x + 12/ 5x + 3
To get the other length, we can factorize the algebraic expression;
5x2 + 23x + 12
Product: 60x^2 (20x × 3x)
Sum: +23x (20x + 3x)
Hence;
= 5x^2 + 20x + 3x + 12
Next, we find factors;
5x (x+4) + 3 (x+4)
Therefore, the factors are (5x + 3) and (x +4)
This means that the other length is (x +4)
Answer:
1110
Step-by-step explanation:
Let x = price of the ticket before tax
We know the ticket plus the tax = 1232.10
x + x*11% = 1232.10
x+.11x = 1232.10
1.11x = 1232.10
Divide each side by 1.11
1.11x/1.11 = 1232.10/1.11
x=1110
Answer:
true
Step-by-step explanation:
To figure this out you have to divide 2.5 by 81 and that would give you 0.03.
