Answer:
Kyle would save more using his 15% off of $1000 coupon.
Explanation:
15 ÷ 100 • 1000 = 150
1000 - 150 = $850
$150 is the amount the 15% coupon took off.
$850 is the amount Kyle will pay.
vs.
1000 - 80 = $920
Answer:
Step-by-step explanation:
Given expression is,
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
To prove this identity we will take the left hand side of the equation and will prove equal to the right side.
(2x - 1)² + 2(2x - 1) = (2x - 1)(2x + 1)
4x² - 4x + 1 + 4x - 2 = (2x - 1)(2x + 1)
4x² - 1 = (2x - 1)(2x + 1)
(2x - 1)(2x + 1) = (2x - 1)(2x + 1) [Since a² - b² = (a - b)(a + b)]
Answer:
1,240
Step-by-step explanation:
Okay so, 8+11=19 then 19+14= 33. 33+602= 635 Finally, 635+605 should = 1,240.
The answer should be 74% probability
35/50+5/50-3/50= 37/50->74%
Answer:r=7/7744
move all terms to the left:
(7/22)(44)-(2r)=0
add all the numbers together, and all the variables
-2r+(+7/22)44=0
multiply parentheses
-2r+7/22*44=0
multiply all the terms by the denominator
-2r*22*44+7=0
multiply elements
-1936r*4+7=0
multiply elements
-7744r+7=0
move all terms containing r to the left, all other terms to the right
-7744r=-7
r=-7/-7744
