I am not sure about this but in my opinion it would be 32 sorry if It's wrong. I hope this helped! :)
(I couldn't understand the question correctly)
Answer:
10p coins does he have 102
Step-by-step explanation:
given data
saves= 10p coins and 20p coins
total = 17 pounds
to find out
how 10p coins does he have
solution
we consider here no of 20p coin = x
so equation will be here
3 × 10 x +20 x = 1700
30 x + 20 x = 1700
x = 34
so that
10p coins = 3 time × 34 = 102
20p coins = 34
so that 10p coins does he have 102
Y=Mx+b
Slope/M= -1
X= 3
Y= -1
-1 = -1(3)+b
-1 = -3 + b
Add +3 to -3 and -1 to cancel -3 out to get (b)
-3+3 = 0 cancel it
-1 +3 = 2
So, b = 2
In an equation it will be written as
y= -1x + 2
In standard form it will be
1x + y = 2
But your official answer will be
B= 2
Y= -1x+2
Answer:
5151.48 cms
Step-by-step explanation:
We have to:
1.68 m is 1680 cm.
Now the rope forms another right triangle. PQB, we can find the value of QB as follows:
tan (71 °) = PQ / QB
Solving:
QB = PQ / tan (71 °)
Replacing we have:
QB = 1680 / 2.9
QB = 579.31
Knowing this value we can find QA using similar triangles PQB and AQP, like this:
QA / PQ = PQ / QB
Solved:
QA = PQ ^ 2 / QB
Replacing:
QA = 1680 ^ 2 / 579.31
QA = 4872
Finally, knowing QA, we can calculate the one we want to know AP:
Sin (71 °) = AP / AB
But AB = QA + QB = 4872 + 579.31, therefore AB = 5451.31
Solved:
AP = Sin (71 °) * AB
Replacing:
AP = 0.945 * 5451.31
AP = 5151.48 cms
Answer: 15 + 2x
Step-by-step explanation:
5b + 2x
5 (3) + 2x
15 + 2x
I think I'm right so I hope it helped!!
