Answer:
0.19 = 19/100
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.19=0.191
Multiply to remove 2 decimal placesy 102 = 100
0.19/1 × 100/100 = 19100
Conclusion
0.19=19100
Answer:
See below
Step-by-step explanation:
You multiply the equations by numbers that will give you the least common multiple of the coefficients.
Suppose you have a system of two equations:
You can choose to eliminate either x or y.
1. Eliminating x
The coefficients of x are 2 and 1. The least common multiple is 2, so you multiply (1) by 1 and (2) by 2 to get
Then you can subtract (3) from (4) and get
4y = 80. Solve for y.
2. Eliminating y
The coefficients of y are 1 and 2.5. The least common multiple is 2.5, so you multiply (1) by 2.5 and (2) by 1 to get
Then you can subtract (6) from (5) and get
4x = 40. Solve for x.
The answer is 3 :) hope helps
Answer:
linear and y = 2x + 19
Step-by-step explanation:
the x- values increment by 2 and the values of y increment by 4
This indicates a linear relationship exists in the form
y = mx + c ( m is the slope and c the y-intercept )
m = = = 2
y = 2x + c ← is the partial equation
to find c use any ordered pair from the table
using (- 5, 9 ), then
9 = - 10 + c ⇒ c = 9 + 10 = 19
y = 2x + 19 ← linear equation
As a check
x = - 7 : y = - 14 + 19 = 5 ← correct value of y
x = - 5 : y = - 10 + 19 = 9 ← correct value of y
x = - 3 : y = - 6 + 19 = 13 ← correct value of y
x = - 1 : y = - 2 + 19 = 17 ← correct value of y
Answer: $38.16
Step-by-step explanation:
0.89 * 3 = 2.67
2.67 + 11.99 + 17.25 + 6.25 = $38.16
