X + y = 47
x - y = 3
--------------add
2x = 50
x = 50/2
x = 25
x + y = 47
25 + y = 47
y = 47 - 25
y = 22
ur numbers are 22 and 25
45°. I’m not sure what the relationship is but I think it’s linear pair ?
Answer:
61 is the rate at which the population changes every year
Step-by-step explanation:
Given
Required
Interpret 61
A linear equation has the form:
or
Where m is the rate
By comparison:
Hence, 61 represents the rate at which the population changes yearly.
<em>The negative sign implies that the populatiin reduces</em>
Answer: A. The molten mixture of rock-forming substances, gases, and water from the mantle
Magma is a mass of molten rock that is found in the deepest layers of the Earth at high temperature and pressure, and that can flow out through a volcano.
The composition of this mass is a mixture of liquids, volatile and solids that when they reach the surface in an eruption becomes lava, which when cooled crystallizes and gives rise to the formation of igneous rocks.
Answer:
2:1 should be the scale factor
Step-by-step explanation:
The original area is 72cm^2 and the trapezoid shown is 36cm^2. 72/2=36 so the scale factor is 2:1 or 1/2 the original trapezoid.
