Step-by-step explanation:
when scaling all dimensions must be multiplied by the same factor.
64 was first scaled ft to in, and then by 2.8/64.
now we need to do the same for the width :
80 × 2.8/64 = 3.5 in
Positive 28 because it’s above the ocean so it’s in the positive see it make sense so if it was below sea level it would be negitive
Answer:
y=0
Step-by-step explanation:
-2(4+3y)=-2(4+y)
-8-6y=-8-2y
+8 +8
-6y=-2y
+2y +2y
-4y=0
-4y/-4=0/-4
y=0
Step-by-step explanation:
3a + 2 = 8 ==> a=2
12 + 2 = c ==> c=14
3b + 2 = 2 ==> b=0
3d - e = 15
4d - e = 21
fd - e = 45
------------------
d=6
e=3
f=7
Hope to helpfull
