We have an equation: ?/100= 50/125
Cross multiply:
125*?= 50*100
⇒ ?= 50*100/125= 40
40% of 125 is 50~
Answer:
y = x +
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
To calculate the slope use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)
m = = , hence
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
using (5, 7 ), then
7 = + c ⇒ c = 7 - =
y = x + ← equation in slope-intercept form
Answer:
AAA (Angle-Angle-Angle) Theorem
Step-by-step explanation:
We see that , is congruent to itself, and is congruent to itself. Thus, with 3 angle congruency statements, we could use the AAA Theorem to prove that the triangles are congruent to each other.
Answer:
Choice C.
Step-by-step explanation:
A parallelogram is a quadrilateral with two pairs of opposite parallel sides.
There is a theorem that states that opposite sides of a parallelogram are congruent.
In this case, sides AB and CD are opposite sides.
Sides BC and AD are opposite sides.
Side CD is opposite side AB, so they are congruent.
Answer:
Choice C.
CD = AB; Opposite sides of parallelograms are congruent.
