Solve (x + 3)(x - x = 0. (2 points) x = 3, x = -8 O x = -3, x = 8 x = 3, x = 8 O x = -3, X = -8​
astraxan [27]

answer:

the answer is -3 and 8

Step-by-step explanation:

we will place -3 in the equation

(x+3)(x-x)=0

(-3+3)=0 (because -3+3 will cut down together)

we will place two 8(eights) in the equation

(8-8)=0

final answer is

(0)(0)=0

so -3 and 8 fits well in the equation

Mary sews at a rate of 60 inches per hour. How many feet does she sew in a minute?
makvit [3.9K]

Answer:

B. 0.083 rounded to the nearest thousandth.

Step-by-step explanation:

It is known that 12 inches = 1 foot and

60 minutes = 1 hour

Since we want to covert from inches per hour to feet per minute, then we would change 60 inches to feet in 1 hour 2 minutes in divide.

If 12 inches = 1 foot, then

60 inches = 60/12 = 5 feet

Therefore, the number of feet that she sews in a minute is

5/60 = 0.083 feet per minute

She sews 0.083 feet per minute.

This is the full explanation for this question.

how is the sentence “12 less than x is four” written as an equation? 12 – 4 – x = 0 x = 12 – 4 x – 4 = 12 x - 12 = 4
nordsb [41]
This is saying that four is the result of a number "x" minus 12....therefore the equation is x-12=4

Susan has 4 times as many quarters as dimes and 16 less dimes than nickels. If she has $13.45 in coins. How many of each coin do
Maslowich

Using a system of equations, it is found that Susan had 44 quarters, 11 dimes and 27 nickels.

--------------------------------

We are going to use:

  • x as the number of quarters.
  • y as the number of dimes.
  • z as the number of nickels.

A <em>quarter </em>is worth $0.25. A <em>dime </em>is worth $0.1, and a <em>nickel </em>is worth $0.05. Total of $13.45, then:

0.25x + 0.1y + 0.05z = 13.45

4 times as many <u>quarters as dimes</u>, thus:

x = 4y \rightarrow y = 0.25x

16 less <u>dimes than nickels</u>, thus:

z = y + 16 = 0.25x + 16

Replacing in the first equation, we find x:

0.25x + 0.1y + 0.05z = 13.45

0.25x + 0.1(0.25x) + 0.05(0.25x + 16) = 13.45

0.2875x = 12.65

x = \frac{12.65}{0.2875}

x = 44

Now, with x, we find y and z:

y = 0.25x = 0.25(44) = 11

z = y + 16 = 11 + 16 = 27

Susan had 44 quarters, 11 dimes and 27 nickels.
