Answer:
The value of x is 3
Step-by-step explanation:
∵ Quadrilateral ABCD is congruent to quadrilateral JKLM
∴ AB = JK and BC = KL
∴ CD = LM and AD = JM
∵ BC = 8x + 7
∵ KL = 31
∵ BC = KL
→ Equate their right sides
∴ 8x + 7 = 31
→ Subtract 7 from both sides
∵ 8x + 7 - 7 = 31 - 7
∴ 8x = 24
→ Divide both sides by 8 to find x
∴ 
= 
∴ x = 3
∴ The value of x is 3
Answer:
2x2 - 5x - 12 = 0.
(2x + 3)(x - 4) = 0.
2x + 3 = 0 or x - 4 = 0.
x = -3/2, or x = 4. I hope this helps

Answer:
Step-by-step explanation:
This is what i get what i understand from your question .
Kurt earns $7 per hour for doing chores. his goal is to make at least $35 each week
So ,
$7 =per hr
X= unknown hrs
$35= goal
7 x =35
Divide both sides by 7 to get x alone representing hrs.
X= 35/7
X= 5
So 5 hrs per week to make 35 a week.
5×7=35
35=35
Interest paid by Linda is equal to $4.272 approximately equal to $4.27.
<u>
Solution:
</u>
Given that
Rate of interest on first $200 = 1.8%
Rate of interest on any amount over $200 = 1.2%
Unpaid balance amount of Linda’s credit card bill = $256
Need to calculate interest paid by her on $256.
Unpaid balance = $256
=$200 + 56
Amount over $200 = 56
Interest paid on first $200 = 1.8% of 200
= 0.018 x 200 = $3.6
Interest paid on amount over $200 that is $56 = 1.2% of 56
= 0.012 x 56 = $0.672
So total interest paid on $256 = 3.6 + 0.672 = $4.272.
Hence interest paid by Linda is equal to $4.272 approximately equal to $4.27.
