If y = -252 when x = 84, what is y when x = 74
MAVERICK [17]
If x =1  y = ?

y = -252/84
y = -3
y = -3*74
y = - 222

we need to calculate the value of y when x =1
we have to divide the value of y by value of x by doing this we can get the value of y is -3 when x=1
when x = 74 we have to multiply the value of x & y (74 *-3)
so the answer is -222

M + t + w = 19
t = 2m
w = t - 6....w = 2m - 6

m + (2m) + (2m - 6) = 19
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25/5
m = 5 <===Monday

t = 2m
t = 2(5)
t = 10 ... Tuesday

w = 2m - 6
w = 2(5) - 6
w = 10 - 6
w = 4 .... Wednesday
