Answer:
simplify: 2.5 =(y+5)
reorder the terms: 2.5y=(5+y)
remove the parenthesis: 2.5y=5+y
solving: 2.5y=5+y
move all terms containing y to the left, all other terms to the right.
add -1y to each side of the equation
2.5y+-1y=5+y+-1y
combine like terms 2.5y+-1y=1.5y
1.5y=5+y+-1y
combine like terms: y+-1y=0
1.5y=5+0
1.5y=5
divide each side by 1.5
y=3.333333333
simplifying
y=3.333333333
Step-by-step explanation:
6^(8x) = 4
log 6^(8x) = log 4
8x log 6 = log 4
x = log 4 / 8log 6 = 0.10 to two decimal places.
Answer:
A x = 3
Step-by-step explanation:
A = ½θR²
R = x
x = √(2Α/θ)
θ = (360 - 60)(π/180) = 5π/3 radians
x = √(2(15π/2) / (5π/3))
x = √(15π(3/5π))
x = √9
x = 3
Answer:
5y-4x= -7 :
Slope =
= 0.800
<em>x </em>- <em>intercept = </em>
= 1.75000
<em>y - intercept = - </em>
= -1.40000 <------both of these numbers a negative

2y+4y = 14 :
<em>y = </em>
= 2.333

Answer:
80%
Step-by-step explanation:
50 x 50 would be 100 and 50kg=100% and 10 x 2 = 20 so you used 20% therefore you have 80% left.
