Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.
Answer:
I believe X>3
Step-by-step explanation:
This is because 2(4+2x)= 8+4x
So, with this 25x-4x=19 and 8-5=3
The answer will be X>3
I hope this helped
Answer:
x=62; scalene triangle
Step-by-step explanation:
There are 180° in a triangle and a straight angle.
You start by subtracting 180-127 to get the angle opposite to the 127 degree angle. This is 53 degrees. Then you subtract the total amount of degrees by adding the two known angles 65+53 and subtracting them by 180. You do this to find the last angle. 180-118=62. x=62°
All of the angles are different so it is a scalene triangle.

Answer:
3.88%
Step-by-step explanation:
The probability that 1 is defective and 3 are not (out of four) is ...
P(1 of 4) = 4(0.01)(0.99)^3 ≈ 0.0388 = 3.88%
__
The multiplier of 4 comes from the number of ways that 1 can be chosen from 4.
