Answer:
So the numbers are 12 and -3.
Step-by-step explanation:
In order to solve this problem we will attribute variables to the numbers, the first one will be "x" and the second one will be "y". From the first sentence we know that the subtraction of the two numbers is equal to 15, so we have:
x - y = 15
Then the problem states that one-third of the sum of the number is equal to one quarter of the first number, so we have:
(1/3)*(x+y) = x/4
Since we now have two equations and two variables we can solve for x and y. From the first equation we have:
y = x - 15
Using this expression for the value of y in the second equation:
(1/3)*(x + x - 15) = x/4
(1/3)*(2*x - 15) = x/4
2*x - 15 = 3*x/4
2*x - 3*x/4 = 15
(8*x - 3*x)/4 = 15
5*x/4 = 15
5*x = 60
x = 60/5 = 12
y = x - 15 = 12 - 15 = -3
So the numbers are 12 and -3.
Round 16.18 to 16.25
round 5.94 to 6.
Do 16.25 - 6, and you get:
10.25
Area is pi r squared=201.06
R squared=201.06/pi
R=square root of 201.06/pi
D=2(square root of 201.06/pi)
Pi d=circumference
Answer=50.265
$70/$32.55=$37.45 the amount of money she spent on coffee. We can divide that amount by $7.49 to see how many pounds she brought $37.45/$7.49=5
She brought 5 pounds of coffee.
Answer:
Answer is 261
Step-by-step explanation:
-4r+5y-14 r=0 y=55
insert "r" and "y" values into equation
=-4(0)+5(55)-14
evaluate;
-4(0)=0
5(55)=275
so, now the equation would look like this;
=275-14
<h2>=261</h2>
