Answer:
The number of dimes is 3n - 8
Step-by-step explanation:
Here, we are interested in writing an expression for the number of dimes.
We proceed as follows;
Now, there are n nickels with the number of dimes been 8 less than 3 times the number of nickels
That would be;
3(n) -8 = 3n -8
Answer:
x = 24.0
y = 46.4
Step-by-step explanation:
Let opposite side = z
Using trigonometry :
Sin 30 = z / 34
z = 0.5 * 34
z = 17
We find x :
Sin 45 = 17 / x
x * sin45 = 17
x = 17 / sin 45
x = 24.04
Let y = y1 + y2
y1 = 17 / tan45
y1 = 17
y2 = 17/tan30
y2 = 29.44
y = 17 + 29.44
y = 46.44
Answer:
(7a + 5) (a + 3)
Step-by-step explanation:
We can factor by grouping which leaves us with (7a + 5) (a + 3) as the answer.
No.
0.36 = 36/100 =9/25
_____
In decimal form, 10/33 = 
which is not 0.36.
How do we multiply each
expression, 6 (h-4)?
In multiplying expressions,
multiply the coefficient which is outside the parenthesis by each term inside
the parenthesis.
For example, in the expression mentioned above, 6 (h-4), the
answer is 6h – 24.
If you remember BODMAS process,
you can never go wrong in Math. BODMAS is a formula saying:
<span>B -- Remove the Brackets
O -- ‘Off’ means multiply
D -- for division
M -- for multiplication
A -- addition
S -- subtraction</span>
