Idk I download this app so other ppl can help me
You can set it up as an equation:
29.95x + 2x
then plug in x = 7.
I'm not sure how this really relates to the distributive property though.
Answer:
7x -14 = jl
Step-by-step explanation:
Assuming a straight line
jm+ ml = jl
5x-8 + 2x-6 = jl
Combine like terms
7x -14 = jl
Hannah wants to buy a $565 bicycle. she can save $50 each week from her paycheck. However, before Hannah can buy the camera, she must give her brother $80 that she owes him. For how many weeks will Hannah need to save before she can pay back her brother and buy the camera
Answer:
See the attached figure.
Step by step solution:
<u>Part (1):</u>
When ΔABC is an isosceles triangle with AB = AC
The summing of the three of the triangle = 180°
∴ m∠ABC + m∠BAC + m∠ACB = 180°
================================================
<u>Part (2):</u>
When ΔABC is an isosceles triangle with AB = AC
So, m∠ABC = m∠ACB = x
if m∠BAC = 70
∵ m∠ABC + m∠ACB + m∠BAC= 180°
∴ x + x + 70 = 180 ⇒ x = 55°
∴ m∠ABC = 55°
===================================================
<u>Part (3):</u>
When m∠QRP = 30°, and ΔPQR is an isosceles triangle with PQ = QR
So, m∠QPR = m∠QRP = 30°
====================================================
<u>Part (4):</u>
When m∠BAC = 45° and points D and E are the midpoints of AB and BC in ΔABC
∵ Points D and E are the midpoints of AB and BC in ΔABC
∴ DE // AC
∴ m∠BDE = m∠BAC ⇒ the corresponding angles are congruent
∴ m∠BDE = 45°
