Answer:
(31zy)/(13xz)
Step-by-step explanation:
A reciprocal is a number that you can multiply the original number by and get a product of 1. To find the reciprocal of a fraction, flip it upside down, putting the numerator in the denominator, and the denominator in the numerator:

If we multiply this fraction by the other, we would end up simplifying it to 1 by cross multiplication.
The distance is 1410 miles.
The triangle above shows how speed, distance and time are related. D = s x t
S= d/t
T=d/s
Area= legnth times width
or sometimes
area=legnth times height
area=measure1 times measure 2 on a flat plane
dependson the names
area=27
height=6
area=legnth times height
subsitute
27=legnth times 6
divide both sides by 6
27/6= legnth
simplified to 4 and 3/4
legnth=4 and 3/4 meter
subsitute
2 1/2 * 5 = 12 1/2 cups of flour are needed to make 5 batches
5/2 * 5/1=25/2 or 12 1/2 cups
Answer:
<em><u>x=9, y=12</u></em>
Step-by-step explanation:
-5x+4y=3
--------A
x=2y-15----------B
Putting the value of x from B in A
-5(2y-15) +4y=3
-10y+75+4y=3
-6y=3-72
-6y=-72
y=72/6= 12
Putting the value of y =12 in B
x= 2(12)-15
x= 24-15
x=9
