Answer:
872
Step-by-step explanation:
Multiply 218 by 3, then add 218.
The least common multiple is 63
Answer:
The Correct Answer are
- The ordered pair (2, 3) is not a solution to the system of linear equations.
- When (2, 3) is substituted into the first equation, the equation is true.
- When (2, 3) is substituted into the second equation, the equation is false.
Step-by-step explanation:
The Correct Answer are
- When (2, 3) is substituted into the first equation, the equation is true.
3x + 4y = 18 equation ( 1 )
3×2 + 4×3 = 18
6 + 12 = 18
18 = 18
- When (2, 3) is substituted into the second equation, the equation is false.
2x – 2y = 2
2×2 - 2×3= 4 - 6 = -2≠2
- The ordered pair (2, 3) is not a solution to the system of linear equations.
Solution means if we (2, 3) Substitute in both the Equation it Must Satisfy
But in Equation 1 it Satisfy
and in Equation 2 Not satisfy
Therefore It is NOT a solution to the system.
Answer:
<em>The sound level would be at 80 decibels at 1 or 7 number of measures played</em>
Step-by-step explanation:
<u>Equations with Absolute Values</u>
We have the function s to represent the sound level in decibels:

Where x is the number of measures of the music played.
We are required to find the value of x that makes s=80 decibels. We have to find the equation:

Subtracting 50:


Dividing by 10:


For the absolute value be equal to 3, its argument could be positive or negative:

Or

This leads us to two solutions:

x=7
Or


x=1
The sound level would be at 80 decibels at 1 or 7 number of measures played
Answer:
52.07
Step-by-step explanation:
sin of an angle is the opposite side over the hypotenuse
sin 51 = x/67
Multiply each side by 67
67 sin 51 = x
52.06877942 =x
Rounding to the nearest hundredth
52.07 =x
