Answer:
the slope is -7
Step-by-step explanation:
If the student got a true statement, it is an identity
example, ending with x=x or 10=10 means it is an identity
if the student ended up with a false statement, there is no solution
example, 10=2
Answer:
56 cm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = h(a + b)
where h is the perpendicular height and a, b the parallel bases
here h = 4, a = 5 + 9 + 5 = 19 and b = 9, thus
A = × 4 × (19 + 9) = 2 × 28 = 56 cm²
Answer:
Height of the recycling box = 75 cm
Explanation:
Volume of a box = Base area of box x Height of box
Volume of the box = 151875 cm³
Base has a square base of side 45 cm
Base area = 45 x 45 = 2025 cm²
151875 = 2025 x Height of box
Height of box = 151875/2025
= 75 cm
Height of the recycling box = 75 cm
Answer: Choice A
Explanation:
= quotient of h and 6
= 7.8 more than the quotient of h and 6
The "is" often refers to "equals" in math translation problems like this.
Another example "h is 10" means "h = 10".
