Answer: x = -7
Step-by-step explanation:
2.5x+10=x-0.5
Collect like terms
2.5x-x= -0.5 -10
1.5x= -10.5
X= -10.5/1.5
X= -7
Answer:
x = 3/2 or x = -5/4
Step-by-step explanation:
Solve for x over the real numbers:
8 x^2 - 2 x - 15 = 0
Using the quadratic formula, solve for x.
x = (2 ± sqrt((-2)^2 - 4×8 (-15)))/(2×8) = (2 ± sqrt(4 + 480))/16 = (2 ± sqrt(484))/16:
x = (2 + sqrt(484))/16 or x = (2 - sqrt(484))/16
Simplify radicals.
sqrt(484) = sqrt(4×121) = sqrt(2^2×11^2) = 2×11 = 22:
x = (2 + 22)/16 or x = (2 - 22)/16
Evaluate (2 + 22)/16.
(2 + 22)/16 = 24/16 = 3/2:
x = 3/2 or x = (2 - 22)/16
Evaluate (2 - 22)/16.
(2 - 22)/16 = -20/16 = -5/4:
Answer: x = 3/2 or x = -5/4
The perimeter of the minor segment is 77. 4m
<h3>How to determine the perimeter</h3>
The formula for determining the perimeter of the minor segment is given as;
Perimeter = θ/360 × 2πr + 2r sin θ/2
where;
Substitute into the formula;
Perimeter = (72/360 × 2 × 3. 142 × 24. 5) +( 2 × 24. 5 × sin 72)
Perimeter = 30. 79 + 46. 60
Perimeter = 77. 4 m
Thus, the perimeter of the minor segment is 77. 4m

$199.95 x 25% = $199.95 x .25 = $49.9875 ~ $49.99
$199.95 - 49.99 = $149.96 (actual balance) If Lenny pay $14.99 for 12 months the total payment would be: $14.99 x 12 =$179.88
Lenny would have paid an additional amount of $29.92 ($179.88 - 149.96) after making the final payment.
I hope this helps since you did not mention what you were calculating, so I include everything that can be done to this problem.
