C = 15x + 50
let c be $125 since c represents the cost
15x + 50 = 125
15x = 125 - 50
15x = $75
x = 75 ÷ 15
x = 5
Given a variable, x, the compound ineaquality representing the range from a to b inclusive of the variable is given by

where a is the least value and b is the greatest value.
Thus, given a variable f, representing the frequencies for the three octaves of a <span>typical acoustic guitar.
</span>
Where the range of the frequencies is between 82.4 Hertz and 659.2 Hertz inclusive.
The complex inequality, representing <span>the range of frequencies for a guitar tuned to "concert pitch"</span> is given by
Answer:
(77, 77)
Step-by-step explanation:
Carry out the indicated multiplication:
3(-0.8, 6.3) → (-2.4, 18.9)
Next, combine like terms:
(79.4, 58.1) + (-2.4, 18.9). In other words, combine the x terms 79.4 and -2.4 separately and then the y terms 58.1 and 18.9 separately:
(79.4, 58.1) + (-2.4, 18.9) → (77, 77)
According to the Triangle Midsegment Thereom, if the midsegment of a triangle is parallel to a side of the triangle, then the midsegment is half the length of side it is parallel to, therefore...
45=(7x+13)/2
And after that, you continue to solve the problem using Algebra
90=7x+13
77=7x
11=x
