Answer:
6.
Step-by-step explanation:
We can start by defining a couple things.
x = amount of nickels
y = amount of dimes
Since he has the same amount of each, we can say this.
x = y
And because we know it totals 0.90, we can say this.
0.05x + 0.10y = 0.90
then, we substitute and get this.
0.05x + 0.10x = 0.90
Simplify.
0.15x = 0.90
Divide both sides by 0.15.
x = 6
So we have 6 nickels, and they both are the same, so we have 6 dimes.
Answer:
y =
x + 8
Step-by-step explanation:
The equation of a line in slope- intercept gorm is
y = mx + c
Given
3x - 2y = - 16 ( subtract 3x from both sides )
- 2y = - 3x - 16 ( divide all terms by - 2 )
y =
x + 8 ← in slope- intercept form
71/100 is the lowest the fraction can get
Answer:
A =12.92 cm^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
A = 1/2 ( 7.6) ( 3.4)
A =12.92 cm^2
