If you laid 16 bolts that each measure 7/8 inch end to end how many feet long would the row of bolts be

2 answers:

8 0

The answer is 1 1/6 feet....this is because to find the number of inches all 16 bolts would measure, you would do:

7/8 *16=14 in.

Then to find the number of feet, you would divide 14 by 12(number of in. in a ft), and you would get 1 1/6

7/8*16
16/1*7/8
112/8
14 inches; 14 inches = 7/6 ft or about 1.2 ft

Because the two angles equal each other:

Simplify 4.2(2x-0.5y)-2(4.1x-0.3y)

klio [65]

Answer:

x = 7.5y

Step-by-step explanation:

Simplifying

4.2(2x + -0.5y) + -2(4.1x + -0.3y) = 0

(2x * 4.2 + -0.5y * 4.2) + -2(4.1x + -0.3y) = 0

(8.4x + -2.1y) + -2(4.1x + -0.3y) = 0

8.4x + -2.1y + (4.1x * -2 + -0.3y * -2) = 0

8.4x + -2.1y + (-8.2x + 0.6y) = 0

Reorder the terms:

8.4x + -8.2x + -2.1y + 0.6y = 0

Combine like terms: 8.4x + -8.2x = 0.2x

0.2x + -2.1y + 0.6y = 0

Combine like terms: -2.1y + 0.6y = -1.5y

0.2x + -1.5y = 0

Solving

0.2x + -1.5y = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '1.5y' to each side of the equation.

0.2x + -1.5y + 1.5y = 0 + 1.5y

Combine like terms: -1.5y + 1.5y = 0.0

0.2x + 0.0 = 0 + 1.5y

0.2x = 0 + 1.5y

Remove the zero:

0.2x = 1.5y

Divide each side by '0.2'.

x = 7.5y

Simplifying

x = 7.5y

Christy earned $41.25 for selling 3 birdhouses at a craft market. The equation y=13.75x can be used to represent this situation.

kobusy [5.1K]

K=y/x

k=68.75/5 (you can pick any number by multiplying x by 13.75)

k=13.75

16 emails to 6 text messages- 10 emails to 4 text messages proportional or not

Pavel [41]

Given:

16 emails to 6 text messages- 10 emails to 4 text messages

To find:

Whether 16 emails to 6 text messages- 10 emails to 4 text messages proportional or not.

Solution:

Check the ratio of emails to text. If the ratios are equal then the relation is proportional.

16 emails to 6 text messages.

$\dfrac{Emails}{Text}=\dfrac{16}{6}$

$\dfrac{Emails}{Text}=\dfrac{8}{3}$

$\dfrac{Emails}{Text}=8:3$

10 emails to 4 text messages.

$\dfrac{Emails}{Text}=\dfrac{10}{4}$

$\dfrac{Emails}{Text}=\dfrac{5}{2}$

$\dfrac{Emails}{Text}=5:2$

Since $\dfrac{8}{3}\neq \dfrac{5}{2}$ or $8:3\neq 5:2$ , therefore, it is not proportional.
