There are 2 dollars so that would equal 20 dimes.
Proof:
10 cents = a dime
20 x 10 = 200 = 2 dollars
__
There are 35 cents to that would equal 3 dimes and 1 nickel.
Proof:
10 cents = a dime
5 cents = a nickel
3 x 10 = 30
1 x 5 = 5
__
So the final answer would be 23 dimes and 1 nickel.
Answer:
b
Step-by-step explanation:
Using the trigonometric identities
cot x = 
and tan x = 
thus
+ tanΘ × cosΘ
= 
+ 
× cosΘ
= cosΘ × + sinΘ
= sinΘ + sinΘ
= 2sinΘ → b
Answer:
16 + x2 = 0 (16)
I THINK
Step-by-step explanation: Simplifying
3x2 + 48 = 0
Reorder the terms:
48 + 3x2 = 0
Solving
48 + 3x2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-48' to each side of the equation.
48 + -48 + 3x2 = 0 + -48
Combine like terms: 48 + -48 = 0
0 + 3x2 = 0 + -48
3x2 = 0 + -48
Combine like terms: 0 + -48 = -48
3x2 = -48
Divide each side by '3'.
x2 = -16
Simplifying
x2 = -16
Reorder the terms:
16 + x2 = -16 + 16
Combine like terms: -16 + 16 = 0
16 + x2 = 0
The solution to this equation could not be determined.
Answer:
x = 2, y= -1 Or (2, -1)
Step-by-step explanation:
Let’s solve the system using substitution. First we can set the equations equal to each other:
x-3= -2x +3
Now solve for x
3x-3= 3
3x = 6
x=2
Now that we have x, we can plug it back into one of the original equations to get y
y= x-3
y= 2-3
y = -1
Finally, the solution to the system of equations is (2, -1).
Farmer Gray planted 300 seeds.
To find this, you simply multiply the number of flower pots (30) by the number of seeds in each pot (10). Thus making the answer 300.
I hope this helps!
