Answer:
well I guess 8(3+7) or 7(8+3)
When you distribute, it would be 6x - 21 + 5
-21 + 5 = -16
this means the answer would be left as 6x - 16
Answer:
There is a total 50 questions.
Step-by-step explanation:
Let x = total questions in the exam
Since 82% of the test was scored correctly, that means 18% of the student's exam was scored incorrectly.
With this information we can write:
(Given that the student made 9 mistakes)
(divide 18% on both sides)
∴ There was a total of 50 questions in the examination.
It's the relation between the arc length of a circle, and the measure of angle. Before radians, we could only measure in degrees, and use pi to convert from arc length and circumference and angle measure. But, with the introduction of radians, it's much easier to map the relation. Hope it helps!
Define natural hazard?
A natural hazard is a natural phenomenon that might have a negative effect on humans and other animals, or the environment. Natural hazard events can be classified into two broad categories: geophysical and biological.
What is the difference between tectonic hazards and weather hazards ?
Tectonic hazards occur when the Earth's crust moves. For example, when the plates move, friction can cause them to become stuck. Tension builds until the plates release, which leads to an earthquake. Climatic hazards occur when a region has certain weather conditions, for example heavy rainfall can lead to flooding.
why do convection currents in the mantle occur?
Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates. Where convection currents diverge near the Earth's crust, plates move apart
