Answer:
232,26
Step-by-step explanation:
because 37×3.14×2=232,26
Rual because negatives move backwards so the higher the number the smaller it is
13. 3(x-6)-8=-2 (you have to plug in x-6 as x in the equation
3x-18-8=-2 (distribute 3)
3x-26=-2 (combine like terms)
3x=24 (subtract 26 to both sides)
x=8 (divide 3 to both sides)
14. -2(3(5y+5)=-4
-2(15y+5)=-4
-30y-10=-4
30y=6
y=1/5
15. (3x-5) +2x = 90
16. Let m be the number of minutes
0.75m+32 = 47
Using this equation you can find the number of minutes.
0.75m = 15 ( subtract 32 to both sides)
m= 20 (divide 0.75 to both sides)
Vera called 20 minutes beyond her allowed minutes.
Here I hope that this helped you out hon :)
Answer:
x = 9
Step-by-step explanation:
We need to find the value of x if the polygons in each pair are similar.
As they are similar, the ratio of their sides are equal.
The sides of first polygon are 6,12 and 4.8. On the other hand, the sides of second polygon are (2x-9) and 18.
So,

So, the value of x is equal to 9.
