Let both numbers be x and (x +4). Since (x + 4) exceeds x by 4
Sum : x + (x + 4) = 32
x + x + 4 = 32
2x + 4 = 32
2x = 32 - 4
2x = 28 Divide both sides by 2
x = 28/2
x = 14
Recall the numbers are x, and (x +4): 14, and (14 +4) = 14 and 18
The two numbers are 14 and 18
Answer:
9,103.69
Step-by-step explanation:
y = A(d)^x
y = 12000(1-0.129)^2
Decay y = 12000(0.871)^2
solve for y = $ 9,103.69
D.
The graph is widening by a factor of 2, or growing half as fast. Check by plugging in 2 or 4.
Answer:
2 + (13/4)x = 1/2 + (11/2)y
Step-by-step explanation:
Let each jar of paint used by Liam be x
Let each jar of paint used by Evan be y.
Liam uses 2 quarts of yellow paints and adds 3 1/4 jars of blue paint. so we have
2 + 3 1/4x
= 2 + (13/4)x
Since Evan also uses 1/2 quarts of yellow paints and add 5 1/2 jar of red paint, we have
1/2 + 5 1/2y
= 1/2 + (11/2)y
Since they end up with the same volume of paint, we have
2 + (13/4)x = 1/2 + (11/2)y
Answer:
x=15 and y=2
Step-by-step explanation:
The given system of equations is
8y - x = 1 ...............(i)
and
10 y = x + 5 ...............(ii)
Now from equation (ii)
10 y = x + 5
subtracting -5 from both sides
10 y - 5 = x + 5 - 5
10 y -5 = x
or
x = 10y -5 ............(iii)
Put this in equation (i)
it becomes
8y - (10y -5) = 1
8y-10y+5=1
-2y+5 =1
subtracting 5 from both sides
-2y + 5 -5 = 1 -5
-2y = -4
dividing both sides by -2 gives
-2y / -2 = -4 / -2
y = 2
We got the value of y putting it in equation (iii) to get the value of x
as from equation (iii)
x = 10y-5
x = 10(2) - 5
x = 20 -5
x = 15
So this is the solution from the equations
