J1, J2 and J3 are three junctions on a motorway. The distance from J2 to J3 is 8.7 miles. The distance from J1 to J2 is one-thir
leonid [27]

Answer:

11.6 miles

Step-by-step explanation:

Given that:

Distance from J2 to J3 = 8.7 miles

Distance between J1 and J2 = 1/3 of J2 toJ3

Hence, distance between J1 and J2 becomes :

1/3 * 8.7 miles = 2.9 miles

Distance from J1 to J3 equals :

(J1 to J2) + (J2 to J3)

2.9 miles + 8.7 miles

= 11.6 miles

How many 1/3 cups of ice cream can you make from 1/7 cup
OlgaM077 [116]
Well first you have to make the denominators equal by finding a common denominator. in this case 21, but whatever you do to the bottom you do to the top. so 1/3 times 7/7 equals 7/21 and 1/7 times 3/3 equals 3/21.
 
so how many 7/21 cups of ice cream can you make from 3/21 i think  about none but remember i could be wrong

helpppppp pleaseeeeee
Olin [163]

Answer:


Step-by-step explanation:

M' = (8,2)

A' = (7,6)

T' = (2,6)

H' =(3,2)

If this is a reflection across the y axis, then all that will change is the x value. You have to read that carefully to make sure you understand it.

Notice that T = (-2,6). All that happens is the the minus becomes a plus.
