Answer:
5 Hours
Step-by-step explanation:
340 = 215 + 25x
DO INVERSE OPERATIONS ~ MINUS BOTH SIDES OF THE = SIGN
340 - 215 = 125
215 - 215 = 0
125 = 25x
DIVIDE BOTH SIDE NOW
125 / 25 = 5
25x / 25 = 1 = x
<em>5 Hours</em>
(2,3) so x=2, y=3 and h=(2^2+3^2)^(1/2)=√13
sina=3/√13, cosa=2/√13, tana=3/2
Afterwards multiply sina and cosa by √13/√13 and get sina=(3√13)/13 and cosa=(2√13)/13
Answer:
67 degrees
Step-by-step explanation:
alternate exterior angles are always congruent
T = total cost for music school
L = # of lessons
T = $1,190 + ($40 × L)
T = $1,190 + ($40 × 12)
T. = $1,190 + $480
T = $ 1,670 for 12 lessons
Answer:
Step-by-step explanation:
Solving
5x + -2y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
5x + -2y + 2y = 12 + 2y
Combine like terms: -2y + 2y = 0
5x + 0 = 12 + 2y
5x = 12 + 2y
Divide each side by '5'.
x = 2.4 + 0.4y
Simplifying
x = 2.4 + 0.4y
