Answer:
3/4
Area of the small triangle/Area of larger triangle=3/4
Area of the small triangle/Area of larger triangle=(1/2×base of small triangle×length)/(1/2×base of larger triangle×height)
3/4=(1/2×base of small triangle×height)/(1/2×base of larger triangle×height)
Since the length of the triangle are equal the base ratio of the two triangles is the same as area ratio.

Answer:
(b) 5 2/5
Step-by-step explanation:
You can figure this one by estimating. The denominator on the right is a little more than double the numerator. Then the denominator on the left (x) will be a little more than double the numerator. Double is 2(2 1/4) = 4 1/2.
The closest reasonable value is 5 2/5.

If you want to work this out in detail, you will see that ...
x = (2 1/4(3 3/5)/(1 1/2)
x = (9/4)(18/5)(2/3) = (9·18·2)/(4·5·3) = 3·18/10 = 5.4 = 5 2/5

Step-by-step explanation:
Answer:
Part 1) Subtraction Property of Equality
Part 2) This property can be used , because addition and subtraction have inverse relationships
Step-by-step explanation:
we know that
The<u><em> subtraction property of equality</em></u> tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same
so
we have
Solve for y
Applying Subtraction Property of Equality
subtract 10.50 both sides
Remember that this property can be used , because addition and subtraction have inverse relationships.
Among the four choices, theorems is the best possible answer. Postulate, by definition, is a statement that is assumed to be true without proof while theorems are true statements that can be proven. Both of these types of statements are used to justify geometrical equations, illustrations and statements.
