Answer:
Ramon pays $240.
Step-by-step explanation:
30% of $960 is $288, so Glen pays $288
0.45 = 45%
45% of $960 is $432, so Andre pays $432
30% + 45% = 75% meaning Ramon pays 100% - 75% which is 25%.
25% of $960 is $240. So, Ramon pays $240.
You could also add up the payments of Andre and Glen and subtract that sum from $960 to get the same answer.

Answer:
"The sum of two rational numbers is rational."
By definition, a rational number can be expressed as a fraction with integer values in the numerator and denominator (denominator not zero). So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
Find the area of each face and add them all together, or since a cube has 6 faces, you can multiply the area of one face by 6.
Answer is: 32 nickels and 23 dimes.
<span>x - number of nickels .
y -number of dimes.
two equations in two unknowns:
1) x + y = 55
2) 0,05x + 0,1y = 3,90.
</span>nickel is a five-cent coin.
dime is a ten-cent coin.<span>
solve equation 1) for x and substitute for x in equation 2)
x = 55 - y
0,05</span>·(55 - y) + 0,1y = 3,90<span>2,75 - 0,05y + 0,1y = 3,90
0,05y = 1,15
y = 23.
x = 55 - 23 = 32.</span>
