Answers

Let 1 number equal x
Let the other number equal 1/2x + 6

x + (1/2x + 6) =21
1 & 1/2 x + 6 =21

How to solve -10p+9p=12

Answers

we add like terms
to understand this user the distributive property in reverse like this
ab+ac=a(b+c) so we have
-10p+9p=(-10+9)p
we add the terms in the parenthsees
-10+9=9-10=-1
so we have
-1p=12
multiply both sides by -1
p=-12
-10p+9p= 12
⇒ (-10+9)*p= 12 (distributive property)
⇒ -1*p= 12
⇒ -p= 12
⇒ p= -12

Final answer: p=-12~

Monica is buying a new dress for herjob interview at Amazon. The total

(without tax) is $65.49.

If she is shopping in Pearland, where

the sales tax rate is 8.25%, what will

be the AMOUNT OF SALES TAX for

her dress (remember to round to two

decimal places since it's money)?

What’s the answer

Answers

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

3.78 divided by 0.9​

Answers

Answer:

4.200

Step-by-step explanation:

Change the divisor 0.9 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

37.8 ÷ 9 = 4.200

and therefore:

3.78 ÷ 0.9 = 4.200

Both calculated to 3 decimal places.

Final answer:

The division of 3.78 by 0.9 equals 4.2 after rounding to the nearest tenth. The given problem is an arithmetic division question typically encountered in mathematics. The keyword 3.78 is the number being divided by 0.9.

Explanation:

The division question posed: 3.78 divided by 0.9, is a simple arithmetic problem. To solve, we will perform the division calculation directly. First, we divide 3.78 (the dividend) by 0.9 (the divisor). This yields a quotient of approximately 4.2. Thus, 3.78 divided by 0.9 equals 4.2 when rounded to the nearest tenth. This division problem would be typically encountered in arithmetic, a branch of mathematics that deals with numbers and numerical computation.

Can u please answer this question

One Way:
We can change the mixed number to a decimal for comparing.

1(1)/(4) m = (5)/(4) m = 1.25 m

1.4 m     >    1.25 m
Darren   >     Luke

Darren's jump was higher by (1.4-1.25) 0.15 m

Or another way change the decimal to a fraction and the mixed to an improper fraction too.

1(1)/(4)(5)/(4) (Luke)
1.4 = (7)/(5)                               (Darren)
We need a common denominator to compare
(5*5)/(4*5)       (Luke)
(7*4)/(5*4)       (Darren)
(25)/(20)          (Luke)
(28)/(20)          (Darren)

(28)/(20)  >   (25)/(20)
        Darren           >            Luke
  
By:
(28)/(20)(25)/(20)(3)/(20)
Which is also by 0.15 m
Darren jumps higher and by 0.15 m
