The correct equation would be: 2.) 0.05(x+4) + 0.10x = $1.25
A nickel is worth 5 cents. A dime is worth 10 cents.
no. of nickels = x + 4
no. of dimes = x
nickels + dimes = 1.25
0.05(x + 4) + 0.10x = 1.25
0.05x + 0.20 + 0.10x = 1.25
0.15x = 1.25 - 0.20
0.15x = 1.05
0.15x/ 0.15 = 1.05 / 0.15
x = 7 *no. of dimes.
no. of nickels = x + 4 = 7 + 4 = 11
To check:
0.05(11) + 0.10(7) = 1.25
0.55 + 0.70 = 1.25
1.25 = 1.25
Answer:
d = 11 units if rounded to nearest whole number
Step-by-step explanation:
Distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Your ordered pairs (-1, 1) and (4, 11)
d=√((4-(-1))²+(11-1)²)
d=√((4+1))²+(10))²)
d=√((5)²+ 100)
d = √125
d = 11.18
d = 11 units if rounded to nearest whole number
(n+1)x 2=10
2n+2=10
2n=8
n=4
Hello!
Slope-intercept form is written as: y = mx + b. In this equation, m is the slope and b is the y-intercept.
Given the slope, 7/6, and the y-intercept of (0, 6), we can write the completed equation.
Therefore, the equation is y = 7/6x + 6.
