Solve using Combining Like Terms (CLT) 7 + 4d + 5d = 7d + 3

Mathematics
1 answer:
Vesnalui [34]3 years ago
3 0

Answer:

d= -2

Step-by-step explanation:

7 + 4d + 5d = 7d + 3

Combine like terms

7+9d = 7d+3

Subtract 7d from each side

7+9d-7d = 7d-7d+3

2d +7 = 3

Subtract 7 from each side

2d+7-7 = 3-7

2d = -4

Divide each side by 2

2d/2 = -4/2

d = -2

Alenkasestr [34]

Answer:

The domain is t ≥ 0

The range is D ≥ 0

Step-by-step explanation:

rate = \frac{distance}{time}

D(t) = 100t + d₀

t is the time measured in hours.

d₀ is the initial position of the train.

We can assume the distance they go is not negative so...

The domain is t ≥ 0

The range is D ≥ 0

Monica is buying a new dress for her
mina [271]

Answer: Sales tax would be $5.40

Step-by-step explanation: The sales value itself of the dress (that is, without tax) is $65.49.

The amount charged as sales tax in Pearland is given as 8.25% (or 0.0825).

Hence if she is shopping in Pearland, the AMOUNT OF SALES TAX she would pay can be calculated as,

Sales tax = Sales price x 0.0825

Sales tax = 65.49 x 0.0825

Sales tax = 5.402925

Approximately to two decimal places, the sales tax becomes $5.40
