Answer:
the one with 12, 18, 22
Step-by-step explanation:
in the first one, 9-3=6 and 6-3=3 so -3 is the constant of the proportionality
in the second one 3-1=2, 2-1=1 so here the constant of proprtionality is -1
in the third one 16+2=18, 18+2=20 so the constant of proportionality is 2
fourth one 4 + 0.5= 4.5 and 4.5+0.5= 5, constant of proportionality is 0.5
fifth one 12+6=18, but 18+6=24
and the rest are all proportional
Answer:
111 grams
Step-by-step explanation:
Total mass: 185 g
The ratio of the mass of fruit to yoghurt is 2 : 3
185/5 = 37 g
37 x 3 = 111 g
Solve by elimination
multiply top by -1
-2x + y = -4
x - y = -2
-x = -6..............so x = 6
2(6) - y = 4
12-y = 4
-8 = -y
so y = 8
(-6,8)
YES IT IS!!
Work:
EQ: y= -x + 4
x= -6
y= 10
y= -x+4
1. 10= -(-6)+4
2. 10= +6+4
3. 10= 10
Answer:
Step-by-step explanation:
To find 5e. El change, find the difference between week 1 and 1.
56.92-(-16.54) = 56.92+16.54 = -73.46.
Note: this is negative, because we are calculating the difference.
Hope this helps
