Answer: -1 = (-3/3)
Step-by-step explanation
You go from one point to another, i started from 3,1 and went to 3,0. I got down -3 which is my rise and right 3 for the run. Tell me if this is correct
Answer:
Alyssa buys 4 cups of frozen fruit puree and 2 cups of yogurt.
Step-by-step explanation:
Here, x = Represent cups of frozen fruit puree
y = Represent cups of yogurt.
The given system of equations by Marni are:
x + y = 6,
2x + 3y = 14
After first step of elimination,the equations are:
-2x - 2y = -12
2x + 3y = 14
Now, ADD BOTH THE EQUATIONS to eliminate the variable x:
-2x - 2y + (2x + 3y) = -12 + 14
or, y = 2
Now, put y =2 in x + y =6, we get
x = 6 - y = 6 -2 = 4
So, x = 4 and y = 2 is the solution of the given system.
Hence, Alyssa buys 4 cups of frozen fruit puree and She buys 2 cups of yogurt.
400/12 = # of dozen needed
.89 * # of dozen needed
400/12=33.33 need 34 dozen
.89*34=$30.26
Answer: -4,3
Step-by-step explanation: -4,-5 is an x-y coordinate.
Based off of what we have seen on coordinate planes, x is horizontal and y is vertical. So, in order find out a stride north of -4, -5, we need to add 8 to -5, since y is the "north/south" of the equation. So:
-5 + 8 = 3
The point is -4, 3
Answer:
x=75, y = 50
Step-by-step explanation:
Solve the following system:
{x + y = 125 | (equation 1)
5 x + 8 y = 775 | (equation 2)
Swap equation 1 with equation 2:
{5 x + 8 y = 775 | (equation 1)
x + y = 125 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 8 y = 775 | (equation 1)
0 x - (3 y)/5 = -30 | (equation 2)
Multiply equation 2 by -5/3:
{5 x + 8 y = 775 | (equation 1)
0 x+y = 50 | (equation 2)
Subtract 8 × (equation 2) from equation 1:
{5 x+0 y = 375 | (equation 1)
0 x+y = 50 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 75 | (equation 1)
0 x+y = 50 | (equation 2)
Collect results:
Answer: {x = 75
, y = 50
