sub in the numbers
6/3
=2/1
which is basically 2, the first option

Answer:

2

Step-by-step explanation:

x/y equals to 6/3. Simplify it- 6(numerator) can go into 3(denominator) twice, so therefore it is 2.

Or you can divided 6(numerator) by 3(denominator), and get 2.

The total cost of a sweater and a pair of pants was $89.47. If the price of the sweater was $8.53 less than the pair of pants, what was the price of the sweater? Express your answer as a simplified fraction or a decimal rounded to two places.

Answers

Answer:

Let S = price of sweater

Let P = price of pants

S + P = 89.47 because that was the total spent

S = P - 8.53   because the sweater is 8.53 less than pants

Substitute P-8.53 in place of S in the

1st equation and solve for P

P - 8.53 + P = 89.47

2P - 8.53 = 89.47     add 8.53 to both sides

2P = 89.47 + 8.53

2P = 98.00  divide both sides by 2

P = 98.00/2

P = $49.00

S = P - 8.53

S = 49.00-8.53

S = $40.47

A sweater costs $40.47 and the pants cost $49.00

You estimate that there are 32 candies in a bag.
and find there are actually 29 candies. Find the percent error. Round to the
nearest tenth of a percent if necessary.
a. 0.09%
C. 9.4%
b. 0.10%
d. 10.3%

Answers

Answer:

D. 10.3%

Step-by-step explanation:

Find the percent error using the formula:

percent error = | (observed - expected) / expected | x 100

32 is the observed value, and 29 is the expected value

Plug in these values to solve for the percent error:

percent error = | (observed - expected) / expected | x 100

percent error = | (32 - 29) / 29 | x 100

percent error = 10.3%

So, the correct answer is D. 10.3%

What % of $30 is $21?

Answers

Answer:

70

Step-by-step explanation:

Answer:

x/100 x 30 = 21 (solve for x) x =70

I wish I could explain more but if your just lazy to do this i wont explain but if you honestly dont know I will explain, so solve for x you must multiply by a 100 on both sides and on the right side you multiply it to the fraction so x/100 x 100 = x (variable by itself means 1) then 21 x 100 = 21,000 therefore you are left with 30x since you are multiplying x and 30 together then you will divide by 30 on both sides to get x = 70

B) -5, 5, -7, 7           

Step-by-step explanation:

3x² - bx + 2

factor:

(3x - 2 )(x - 1) = 3x² - (5)x + 2      so 5 does work

(3x - 1 )(x - 2) = 3x² - (7)x + 2      so 7 does work

(3x + 2 )(x + 1) = 3x² + 5x +2    =    3x² - (-5)x + 2      so -5 does work

(3x + 1 )(x + 2) = 3x² + 7x + 2   =    3x² - (-7)x + 2      so -7 does work
