Answer:(-5.6, -1.4)
Step-by-step explanation:
Answer:3 3/8 + 4 1/2 =
get a common denominator
3 3/8 + 4 4/8 = 7 7/8
7 7/8 divided by 1/2
change the mixed number to an improper fraction
(8*7+7)/8 = 63/8
63/8 divided by 1/2
copy dot flip
63/8 * 2/1
63/4 =
15 3/4 bags of grapes
Step-by-step explanation: Hope this helps
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
Answer: cheese pizzas = 25 , Pepperoni pizzas = 15
Step-by-step explanation:
Let x = Number of cheese pizzas, y = Number of pepperoni pizzas.
As per given,
Multiply 7 on both sides of (i), we get
Eliminate (iii) from (ii), we get
Put value of y in (i) , 
Hence, cheese pizzas = 25 , Pepperoni pizzas = 15
