You can only add/subtract like terms so:

2a+ab+2b+4a^2-3ab+9

2a-2ab+2b+4a^2+9  (the only like terms were ab and -3ab)

A rental car company charges $40.18 per day to rent a car and $0.05 for every mile driven. Jacob wants to rent a car, knowing th
Harlamova29_29 [7]

Answer:

b) 270 ≥ 40.18d + 3.75

Step-by-step explanation:

Per day is a variable, so it's 40.18d

Per mile is also a variable so 0.05m

40.18d + 0.05m ≤ 270

40.18d + 0.05(75) ≤ 270

40.18d + 3.75 ≤ 270

If an answer for this question is not a whole number, enter it as a decimal.
Naily [24]

Answer:  The answer would be A.  Or if that is what you are asking.

Step-by-step explanation:

When you multiply decimals, you multiply like how you would for any other set of numbers. (It doesn't matter if you line the decimal points up or not.)

The only difference between multiplying normal numbers and decimals is the decimal point. How many digits there are to the right of the decimal point is how many times you move the decimal point for the new number to the left.

In the decimals 5.15 and 0.3, there are three digits to the right of the decimal in all, so, when you work this problem and come out with 1545, you move the decimal point to the left three times.

1^545

So the decimal point goes right between the 1 and the 5.

Hope I made it clear enough

On a 300 point standardized test, Luca earned 82% of the points. How many of the 300 points did Luca earn?
Zina [86]

Answer:

1. He earned 246

82% = 0.82

Move decimal right twice

82 x 300 is 24600

Move decimal left twice

= 246

2. 25

Solve for Y (Total Diamonds)

12 = 48% × Y

12 = \frac{48}{100} × Y

Y = 12 × \frac{100}{48}

Y = 12 × 100 ÷ 48

Y = 25

3.80.95%

Solve for "%"

% = 34/42

% = 0.8095 (rounded)

Convert decimal to percent using percent formula:

% = 0.8095 × 100 = 80.95%
