Wilson is 6 years older than mary. wilson's age is 10 years less than five times mary's age. the equations below model the relationship between wilson's age (w) and mary's age (m):

w = m + 6
w = 5m − 10

which is a possible correct method to find wilson's and mary's ages?

solve w + 6 = 5w − 10 to find the value of w.
write the points where the graphs of the equations intersect the x axis.
solve m + 6 = 5m − 10 to find the value of m.
write the points where the graphs of the equations intersect the y axis.

Wilson is 10

Mary is 4

Step-by-step explanation:

Wilson is 6 years older than Mary

w=6+m

Wilson is 10 less than 5 times Mary's age

w=-10+5m

w=5m-10

Now we set them equal to each other since both equal w

m+6=w=5m-10

m+6=5m-10

subtract m from both sides

6=4m-10

add 10 to both sides

16=4m

divide both sides by 4

4=m

sub back

w=m+6

w=4+6

w=10

This is the best I can do. Hope it helps either way! :)

4 packs of water and 7 packs of candy bars

step-by-step explanation:

35x4=140

140/20=7

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
