Get x by itself
-3x+10 = 5x-8
10 = 8x-8
18 = 8x
(18/8) = x
Hope this helps!
Answer:
2/3 of band practice was spent playing music.
Step-by-step explanation:
First find the common denominator.
6 times 4 is 24
8 times 3 is 24
multiply the numerators by the same value as the denominator (for 1/8 both the 1 and the 8 would be multiplied by 3, and for 1/6 both the 1 and the six would be multiplied by 4)
4/24 + 3/24
next the questions is asking for the remaining practice time.
add numerators when the denominators are the same.
4 + 3 = 7
= 7/24
24/24 - 7/24 = 16/24
(24 - 7 = 16)
now divide both the numerator and denominator by the same number.
16 ÷ 8 = 2
24 ÷ 8 = 3
The answer would be that 2/3 of band practice was spent playing music.
Answer:
a = 14
Step-by-step explanation:
Since QR = QP then the triangle is isosceles and
QS is a perpendicular bisector, thus
RS = SP ← substitute values
3a = a + 28 ( subtract a from both sides )
2a = 28 ( divide both sides by 2 )
a = 14
first, find the numeric value for 11/15
second to find theta, simply do the <em>inverse</em> cos (which is cos^-1) of the first answer.
now you know theta, just do the sin of 90 - theta and that's it!
since you know whatr cos(theta) is, you just take the inverse cos of that number to get theta and 'reverse' cos, essentially. you are just solving for theta, by reversing the cos function with cos^-1
please mark as brainliest!
