Answer:
w+2,312=2,490
w= 178 pounds
Step-by-step explanation:
Let
W—-^ the amount of weight Bernard lost in pounds
We know that
The amount of weight Bernard lost plus the weight of this week must be equal to the weight of the last week
So…
The linear equation that represents this situation is
w=2,312=2,490
solve for w
Subtract 2,490 - 2,312 = 178lbs

Answer:
450
Step-by-step explanation:
If 81 is 18% of a number then we can say that:
x × 0.18 = 81
We multiply by 0.18 because 18% is 0.18 as a decimal. So to work out the real number we divide 81 by 0.18:
81 ÷ 0.18 = 450
Answer:
The sequence is used to prove AD = BC is
First prove ABC is congruent to CDA, and then state AD and BC are corresponding sides of the triangles.
Step-by-step explanation:
let us assume that ABCD is a parallelogram.
thus AB is parallel to CD
AC is become transversal.
Take ΔADC and ΔABC.
∠DAC =∠ BCA
( by property of alternate angle )
AC = AC
( common side of both triangle.)
∠ACD= ∠BAC
( by property of alternate angle )
Thus by using ASA congruence property.
ΔADC ≅Δ ABC
Thus
AD = BC
( By corresponding part of the congruent triangle property )
Hope this helped!
