Find the x-intercept of the line 20x - 17y = 15.
Write your answer as an integer or as a simplified proper or improper fraction, not as an
ordered pair.
Answers
Step-by-step explanation:
the line is
20x - 17y = 15
I am not sure what your teacher uses as "standard form".
the works is split between "point-slope" and "slope-intercept" form as "standard".
I usually pick "slope-intercept" :
y = ax + b
with a being the slope and b being the y-intercept.
in any case, we can find the x-intercept without bringing the line equation to one of these forms.
because x-intercept simply means that y = 0.
and for y=0 the original equation is then
20x - 17×0 = 15
20x = 15
x = 15/20 = 3/4
Final answer:
The x-intercept of the line 20x - 17y = 15 is the value of x when y equals zero. Using this condition, the equation becomes 20x = 15. Solving for x, we get x = 15/20 or x = 3/4.
Explanation:
To find the x-intercept of the line 20x - 17y = 15, we first set y to zero because the x-intercept is the value of x when y equals zero.
So, we have 20x - 17(0) = 15, which reduces to 20x = 15. Then we solve for x by dividing both sides by 20, obtaining x = 15/20 or 3/4.
Therefore, the x-intercept of the equation 20x - 17y = 15 is 3/4.

D. 860 square inches
Answer:
D: 860 square inches
Step 1.
Remember:
w = 8
x = 5
y = 20
z = 11.3
Let's start with the bottom rectangular prism. The front and back of it is x * x
(5 * 5), so the from and back is 25 + 25 = 50.
The three long sides are x * y (5*20), so the three long rectangles are 100 * 3 = 300. The bottom shape is 350 in total.
Step 2.
The top two rectangles are w * y, (8 * 20) so the two top rectangles are 160 * 2 = 320.
The triangles are w * w / 2 (8 * 8/2) (64 / 2) (32), so the two triangles are 64.
We subtract x from z to get 6.3.
Then, we multiply 6.3 by 20. We get 126. Finally, we add all the values together to get our final answer.
350 + 384+126 = 860
Our answer is D: 860.

party.
Now it is given that:
If the guests only ate three-quarters of the amount he cooked,
We have to find the amount they ate?
( Three-quarters is an amount that is three out of four equal parts of something )
i.e. the guest ate:
3/4 of 7 kg of mashed potatoes.
