Step-by-step explanation:
4x = 112
× = 112 ÷ 4
× = 28
Corresponding angles are equal
y = 28
Solving these is quite simple; think of "a number" as a value of either n or x (depending on personal preference) then just find the operations being done based on key words;
1. Sum= addition so it is x+5
2. Decrease= subtraction so it is 11-n
3. Quotient= division so it is -9/y
4. Twice= multiply by two, minus= subtract, so it is 2n-13
Answer:
1. True
2. False
3. False

Step-by-step explanation:
Volume of a pyramid is:
V = ⅓ AH
where A is the area of the base and H is the height of the pyramid.
The base is a triangle. Area of a triangle is:
A = ½ bh
where b is the base length and h is the height.
A = ½ (4)(1.5)
A = 3
V = ⅓ (3)(9)
V = 9
The volume is 9 in³.
The answer for this problem is 12
