Answer:

1) 6x = 21

2) x + y - 3

3) x/z = y

4) 2-x = p

Step-by-step explanation:

1. The product of a number x and 6 is 21

A product is a multiplication.  A product of a and b is a * b.

We then have a product of x and 6, that x * 6, which we write usually in the format 6x.

is 21: that means it's equal to 21....

so 6x = 21.

2. The sum of the quantity x- 3 and y  

The sum is an addition.  The sum of a and b is a + b.

In this case, the first part is x - 3, the second part is y

So, x - 3 + y, which we usually rewrite as x + y - 3

3. The quotient of x and z is y

A quotient is a division.

So, quotient of x and z is x/z.

x/z = y

4. The difference of 2 and x is p.

A difference is a subtraction.

Difference of 2 and x is 2 - x

2 - x = p

Answer:

1. 14

2. 20

3. 12

4. -400

5. 6

6. 21

7. 11

8. 16

9. 40

10. 49

11. 12

12. IDK

Step-by-step explanation:

1. 16-2=14

2. 16+4=20

3. 6 X 2 = 12

4. -400/-10 (negative divided by a negative equals a positive) = 40

5. 6 X 6 = 36

6. 16+5=21

7. 23-12=11

8. 4 X 16 = 64

9. 36-16=20, 20 X 2 = 40

10. 400-8=392, 392/8= 49

11. 912-612=300, 300/25 = 12

12. Sorry too confusing.

What is AE?<br> Enter your answer in the box?
Nataly [62]

Answer:

AE = 18 units

Step-by-step explanation:

Δ AEB and Δ DEC are similar , then corresponding sides are in proportion, that is

\frac{AE}{DE} = \frac{AB}{DC} , substitute values

\frac{2x+4}{x+8} = \frac{12}{10} ( cross- multiply )

10(2x + 4) = 12(x + 8) ← distribute parenthesis on both sides

20x + 40 = 12x + 96 ( subtract 12x from both sides )

8x + 40 = 96 ( subtract 40 from both sides )

8x = 56 ( divide both sides by 8 )

x = 7

Then

AE = 2x + 4 = 2(7) + 4 = 14 + 4 = 18 units

The water level of a river is 170 feet. The river recedes 4 feet each year. Ingrid claims that the equation that represents this
Vladimir [108]

Sample Answer: No, Ingrid is incorrect. The initial value in the scenario is 170 feet, which represents the y − intercept. Receding 4 feet in the scenario represents the rate of change, which is the slope. In slope-intercept form, y = mx + b, where m represents slope and b represents the y−intercept, so the correct equation is y = −4x + 170.
