Answer:
On average, the workers dig 4.75ft each day. Also, what x and y questions?
Step-by-step explanation:
Take ![38/8=4.75](https://tex.z-dn.net/?f=38%2F8%3D4.75)
I hope you have a great day and make me the brainliest.
Step-by-step explanation:
![= 8x > 48](https://tex.z-dn.net/?f=%20%3D%208x%20%3E%2048)
Now , divide both side by the same number...
![= 8x \div 8 > 48 \div 8](https://tex.z-dn.net/?f=%20%3D%208x%20%5Cdiv%208%20%3E%2048%20%20%5Cdiv%20%208)
![= x > 6](https://tex.z-dn.net/?f=%20%3D%20x%20%3E%206)
Answer:
The equation relates the variables is y = 8x ⇒ D
Step-by-step explanation:
If x and y vary directly (y ∝ x), then y = k x, where
- k is the constant of variation
- k can be found using the initial value of x and y
∵ The variable x and y vary directly
∴ y ∝ x
→ By using the rule above
∴ y = k x
∵ y = 40 when x = 5
∴ The initial values of x and y are x = 5 and y = 40
→ Substitute them in the equation above to find k
∵ 40 = k(5)
∴ 40 = 5k
→ Divide both sides by 5
∵
= ![\frac{5k}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5k%7D%7B5%7D)
∴ 8 = k
→ Substitute the value of k in the equation above
∴ y = 8x
∴ The equation relates the variables is y = 8x
Answer:
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary, so ...
∠B +∠D = 180°
(3x -4) +(2x -6) = 180
5x = 190 . . . . . . . . . . . add 10, collect terms
x = 38 . . . . . . . . . . . . . divide by 5
∠D = 2(38) -6 = 70
∠B = 180 -70 = 110
The measures of angles B and D are 110° and 70°, respectively.
