An integer is a whole number, positive or negative. A rational number is a number which can be expressed as a fraction between 2 whole numbers. An integer is a rational number, because every integer can be expressed as a fraction between itself and 1, both whole numbers.
Step-by-step explanation:
Answer:
area = 250 in²
Step-by-step explanation:
5 x 2.5 = 12.5 in
8 x 2.5 = 20 in
area = 20 x 12.5 = 250 in²
Try this solution:
1. if 1st number is 'x', the 2d number is 'y', then it is possible to make up the system of two equation according to the condition:

2. one number is 11, another number is 10.
7x/x-4 * x/x+7
mutiply the numerators together
(7x)(x)= 7x^ 2
mutiply the denominators together
(x-4)(x+7)
(x)(x)(7)(x)= x^2+7x
(-4)(x)(-4)(7)= -4x-28
x^2+7x-4x-28
x^2+3x-28
Answer:
7x^2/x^ 2+3x-28
1. Parenthesis:
(15)8 - 4 + 2 + 1
Multiply:
120 - 4 + 2 + 1
Subtract:
116 + 2 + 1
Add:
119, the answer is A.
2. 8 x 15 = 120
120 / 2 = 60
6 x 15 = 90
90 + 60 = 150
The answer is A.
Hope this helps!
