Let's translate each sentence into "Math".
Pineapple = p
Orange = x
is means equal
Pineapple is 7 times as heavy as an orange: p = 7x
Pineapple weighs 870 grams more than orange. p = 870 + x
Substitute p = 7x into the second equation:
7x = 870 + x
Subtract x from both sides
6x = 870
divide by 6
x = 145
The orange weighs 145 grams.
The pineapple weights 7 times the orange = 7(145) = 1015 grams.
5*8=40=80%
0.5*4=2=4%
40+2=42
42/50=42:50=21:25
7.5*90=67.5
0.75*6=4.5
67.5+4.5=72
72/75=72:75=24:25
21:25,24:25
b is better
Answer:
it would be 25%
Step-by-step explanation:
because 25 multipled by 4 is 100 so it would be 25%
The store receives 7 new movies per week.
In
1 week, it receives (7 x
1) = 7 new movies.
In
2 weeks, it receives (7 x
2) = 14 new movies.
In
3 weeks, it receives (7 x
3) = 21 new movies.
In
4 weeks, it receives (7 x
4) = 28 new movies.
.
.
In
92 weeks, it receives (7 x
92) = 644 new movies.
.
.
In
'w' weeks, it receives (7 x
w) = (7w) new movies.
Call this ^ number 'm' .
3.a). As you can see from all of that /\ ,
the equation is
m = 7w .
"The number of new movies 'm' received
in 'w' weeks is 7w ."
3.b). The table is:
' w ' ' m '

28
5 35
6 42
7 49
The graph is attached.
