Answer:
x = - 16
Step-by-step explanation:
The equation relating two proportional quantities is
y = kx ← k is the constant of proportionality
To find k use the condition when y = 1, x = - 4
k = 
= - 
y = - x ← equation of proportionality
when y = 4, then
4 = - x (multiply both sides by - 4 )
x = - 16

Answer:
<h3><em>t° = 55°</em></h3>
Step-by-step explanation:
t° + 55° = 90° (Exterior angle of a triangle is equal to the sum of the opposite interior angles.)
4.76 rounded to one decimal place is 4.8
Look at the decimal place you want to round (the 7, since it is the one decimal place).
Then look at the next digit (the 6). If it is 5 or greater, round up. Otherwise, round down.
You round up the 7 up because 6 is 5 or greater.
So you get the answer 4.8
Answer:
2 = 2 (Identity)
Step-by-step explanation:
1/3 (x+2)=-2/5 (x-9) and x=4
Follow distributive property
1/3x + 2/3 = -2/5x + 18/5
Replace x for 4
1/3(4) + 2/3 = -2/5(4) + 18/5
4/3 + 2/3 = -8/5 + 18/5
Add like terms
6/3 = 10/5
Simplify
2 = 2
Also known as Identity
