1. Seven multiplied by three
7*3 the little star mean times
2. Twice the opposite of eleven= 2x+11
22 less than 3 times the number
3x-22
3x-22=2x+11
3x-2x=11+22
x= 33
So , it would be 2x+11 x is 33
Hope this helps good luck
Answer:
70
Step-by-step explanation:
We know that to find the area of a triangle, you need is formula:
(base*height)/2
The height is 10 m and the base is 14 m, so the area is:
(10 m*14 m)/2
=140 m/2
=70 m
The area of the triangle is 70 m.
Congruent means they are the same length.
Set both lines equal to each other and solve for x:
x + 5 = 2x -10
Subtract x from both sides:
5 = x -10
Add 10 to both sides:
x = 15
Now you have a value for x, replace x in the equation of the line and solve:
QR = x +5 = 15 +5 = 20
Volume of a cylinder is pi*r^2*h so we get
3.14*4.5^2*10=636.2cubic feet or ft^3
