Y=19x+19b
To solve for b you first need to subtract 19x from both sides giving you:
y-19x=19b
Then, divide by 19 on both sides to get
(y/19)-x=b
So b=(y/19)-x

$0.30
Step-by-step explanation:
1 bar of candy = $0.20
3 bars of candy = $0.50
To solve, multiply for both:
If you pay for each candy bar individually, they each cost $0.20. Multiply 9 with 0.20:
9 x 0.20 = $1.80
If you pay for the candy bars by 3's, they cost $0.50 each pack. Divide 9 with 3, then multiply by 0.50:
9/3 = 3
3 x 0.50 = $1.50
Subtract the total cost of the individual from the pack:
$1.80 - $1.50 = $0.30
. $0.30 is your answer.
Answer:D
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 8.5%/100 = 0.085 per year
putting time into years for simplicity
6 months ÷ 12 months/year = 0.5 years
then, solving our equation
I = 10000 × 0.085 × 0.5 = 425
I = $ 425.00
on a principal of $ 10,000.00
at a rate of 8.5% per year
for 0.5 years (6 months) is $ 425.00
Answer:
Go to desmos and it will answer literally all of your graphing questions. Just type in desmos graphing calculator.
Step-by-step explanation:
The sum of the opposite interior angles is equal to the exterior angle.
So,
∠CAB + ∠ACB = ∠CBD
x + 40 + 3x + 10 = 6x
4x + 50 = 6x
2x = 50
x = 25°
∠CAB = x + 40 = 25 + 40 = 65°
Hence, the answer is D.
