Answer:
bro use the dang fromula
Step-by-step explanation:
L*W=A divided by 2
Question 1:
For this case, the first thing we must do is define variables.
We have then:
x: number of nickels
y: number of dimes
We write the system of equations that adapts to the problem.
We have then:
0.05x + 0.10y = 6.10
x + y = 67
Solving the system we have:
x = 12
y = 55
Answer:
there are 12 nickels
Question 2:
For this case, the first thing we must do is define variables.
We have then:
x: Allan's score
y: Dave's score
We write the system of equations that adapts to the problem.
We have then:
x + y = 375
x = 2y-60
Solving the system we have:
x = 230
y = 145
Answer:
Dave: 145 Allan: 230
Answer:
56.3
Step-by-step explanation:
The third one.
Answer:
y = 7/2x + 2
Step-by-step explanation:
To put the equation in slope intercept form [ y = mx + b ], we need to solve for y.
14x = 6y - 12
~Subtract 6y to both sides
14x - 6y = -12
~Subtract 14x to both sides
-6y = -12 - 14x
~Divide -6 to everything
y = 2 + 7/3x
~Reorder
y = 7/2x + 2
Best of Luck!
(-3*cos30,-3*sin30)+(9*cos32,9*sin32)
but we don't have sin,cos32. are you sure it's 32? or 30?
