Answer:
10 pounds of potatoes would cost $15.
Step-by-step explanation:
Set up proportion.
4/6=10/x
simplify 4/6 into 2/3,
2/3=10/x
cross product,
2*x=3*10
2x=30
x=30/2
x=15
(2 5/14) / (2 5/8 * 1 3/7)....turn them all into improper fractions
(33/14) / (21/8 * 10/7)
(33/14) / (105/28)...when dividing fractions, flip what u r dividing by, then multiply
33/14 * 28/105 = 132/210 reduces to 22/35 <==
One year equals 31536000 seconds
365×24×60×60
Total speed was 1048 mi/(8 h) = 131 mi/h. The car was traveling at half this speed plus half the difference, (131 +19)/2 = 75 mi/h.
The truck was traveling at 75 mi/h -19 mi/h = 56 mi/h.
The steepness of a line is slope. This is how fast y changes with respect to x. It is the rise over the run.
Hope this helps!!
