Solve for a:
-6a + 9 = -7 + 7a
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
-6a + 9 = -7 + 7a
-6a = -7 + 7a - 9
-6a - 7a = -7 - 9
-13a = -16
a = \( \frac{-16}{-13} \)
a = 1\(\frac{3}{13}\)
Blood is created in:
bone marrow
Blood is created in bone marrow and is made up of cells suspended in liquid plasma. Red blood cells carry oxygen, white blood cells fight infection, and platelets are cell fragments that allow blood to clot.
On this circle, line segment CD is the:
radius
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
Which of the following describes the Earth's mantle?
primarily solid
Mantle makes up 84% of the Earth's volume and has an average thickness of approximately 1,800 miles (2,900 km). It is dense, hot, and primarily solid although in places it behaves more like a viscous fluid as the plates of the upper mantle and crust gradually "float" along its circumference.
A fixed pulley is useful for which of the following?
changing the direction of the input force
A fixed pulley is used to change the direction of a force and does not multiply the force applied. As such, it has a mechanical advantage of one. The benefit of a fixed pulley is that it can allow the force to be applied at a more convenient angle, for example, pulling downward or horizontally to lift an object instead of upward.
__________ and __________ pair to strengthen bones.
vitamin D, calcium
Vitamin D helps calcium strengthen bones while also aiding muscle, nerve, and immune system function.
A truck is using a rope to pull a car. Tension in the rope is greatest in which of the following places?
near the truck
Tension is a force that stretches or elongates something. When a cable or rope is used to pull an object, for example, it stretches internally as it accepts the weight that it's moving. Although tension is often treated as applying equally to all parts of a material, it's greater at the places where the material is under the most stress.
