Answer:
b = 57.6
Step-by-step explanation:
23 +3x +13 +2x=180
add the x's
5x
add the others
23+13=36
subtract 36 on both sides
36-36=0
180-36= 144
now get your 5x and divide by 5 on both sides
5/5 cancels out
144/5= 28.8
x= 28.8
now to find b
2·28.8= 57.6
to find 3x do the same
3 · 28.8 = 86.4
now double-check your answer by adding them all up and seeing if it = 180
57.6+86.4+36=180

50
Answer:
S(-7,0) , 2/7
Step-by-step explanation:
To get coordinates of P we can see that
14*(2/7)=4
Now, to get coordinates of S, we have this equation :

Multiply by 7 each side :
2x=-14
x=-7
y=0
Answer:
soln,
price of textbook = $40
tax% = 10%
now,
tax amount = 10% of $40
= 10\100*40
= 10*4/10
= 40/10
= $4.
again,
final price = cost of textbook+tax
=$40+$4
=$44.
Step-by-step explanation:
so the total price of a Textbook is $40 which is 100% and the tax is 10% so you need to find tax from the price of the textbook which is 10% of the price of the textbook then add the price of the textbook with the tax amount which is the final cost .
