First open the bracket by multiplying with 25
25g -25×7 =3
25g -175 =3
Add 175 to both sides
25g -175+175= 3+175
25g = 178
g = 178/25 is the value.
Answer:
<em>Each friend will get 1/10 of the sandwich</em>
Step-by-step explanation:
<em>1/2/5/1</em>
<em>= (1/2) (1/5)</em>
<em>=(1) (1) (2) (5)</em>
<em>= 1/10</em>
<em>(Decimal: 0.1)</em>
9 x ≥ 117
Divide both sides by 9 :
9 x / 9 ≥ 117 / 9
x = 117 / 9
x ≥ 13
hope this helps!
Answer:
First, a rational number is defined as the quotient between two integer numbers, such that:
N = a/b
where a and b are integers.
Now, the axiom that we need to use is:
"The integers are closed under the multiplication".
this says that if we have two integers, x and y, their product is also an integer:
if x, y ∈ Z ⇒ x*y ∈ Z
So, if now we have two rational numbers:
a/b and c/d
where a, b, c, and d ∈ Z
then the product of those two can be written as:
(a/b)*(c/d) = (a*c)/(b*d)
And by the previous axiom, we know that a*c is an integer and b*d is also an integer, then:
(a*c)/(b*d)
is the quotient between two integers, then this is a rational number.
