Answer: 896
Step-by-step explanation:
Let's use a rule of three here.
Solve for x;
Answer:
0, 5, 10
Step-by-step explanation:
You can solve the inequality to determine what values to select.
28 -7x ≤ -4(-7x -7) . . . . . . given
28 -7x ≤ 28x +28 . . . . . . eliminate parentheses*
-7x ≤ 28x . . . . . . . . . . . . . subtract 28 from both sides
0 ≤ 35x . . . . . . . . . . . . . . add 7x to both sides
0 ≤ x . . . . . . . . . . . . . . . . . divide by 35
So, all values that are 0 or greater will make the inequality true:
0, 5, 10
_____
* Parentheses are eliminated using the distributive property. The factor outside parentheses multiplies each of the terms inside. Pay attention to signs.
-4(-7x -7) = (-4)(-7x) +(-4)(-7) = 28x +28
Answer: 444.6 ft3
Step-by-step explanation:
First, find the area of the base! The base would be the triangle, so the base’s area is 7.6 times 9 divided by 2. That is 68.4 divided by 2 which is 34.2.
Next, you multiply the base times the height, which will be 34.2 times 13.
34.2 times 13 is 444.6 so that is the answer.
