Answer:
The answer to this is 39°
Step-by-step explanation:
because as you can see 23° if you add 16° to 23° then it equals to 39°
3(7v-5)-v(10v-9) = 21v - 15 -10v² + 9v = - 10v² + 30v - 15
Answer: concentration = 15.58%
Step-by-step explanation:
Given: mass of sugar = 24 g = 24 ml [ ∵ 1 g = 1 ml]
Volume of solution = Quantity of water + quantity of solute
= 130 +24 ml
= 154 ml
Concentration = 

Hence, the concentration =15.58%
Paralell has same slope
y=mx+b
m=slope
b=yint
same slope so other equation is
y=4x+b
input given point
(2,0)
x=2
y=0
0=4(2)+b
0=8+b
minus 8 both sides
-8=b
the equation is y=4x-8
