S = sally C = Chris J = Joe
sally is one year older than 3 times the age of joe, so
s = 3j + 1
chris is 5 years younger than 6 times the age of jo, so
c = 6j - 5
sally and chris are the same age so
s = c so
3j + 1 = 6j - 5
-3j -3j
1 = 3j - 5
+5 +5
6 = 3j or
3j = 6
3j/3 = 6/3
j = 2
check
s = c
3(2) +1 = 6(2) - 5
6 + 1 = 12 - 5
7 = 7 correct✅

Step-by-step explanation:
Since she needs 3 1/2 for 5, and you need to find one batch, get 3 1/2 and divide it by 5. Change 3 1/2 to an improper fraction (7/2). Now use KCS (keep change switch) Keep the 7/2, change division to multiplication, and switch 5/1 to 1/5. (7/2)•(1/5)
To solve for

You first need to find a common denominator.
To do so, you need to make both denominators 10 by multiplying the top and bottom of

by 5

=

Reduce by dividing both the top and bottom by 2
Your answer is
The answer here is B. -16
10 + -16 equals -6 and a negative divided by a negative is a positive so -6 divided by -3 is -2.
Hope this helps!
