Answer:
24
Step-by-step explanation:
132 pupils are represented by 11 parts of the ratio
Dividing 132 by 11 gives the value of one part of the ratio
132 ÷ 11 = 12 ← value of 1 part of the ratio, hence
2 parts = 2 × 12 = 24 ← number of teachers on trip
Answer:60.9
Step-by-step explanation:
3 - 14 = 5x + 67 - 5x
11 = 5x + 67 - 5x
11 = 5x + 62x
11 = 67x
11/67
60.9
Answer:
heh
Step-by-step explanation:
Ok, so since it doesn't give a value for "my age", we'll call it x. So the sentence translates into an equation...
200 reduced means... 200 -
by 2 times my age means... 2x
equals 16 means... = 16
200 - 2x = 16
Now let's solve for x to find "my age"
First subtract 200 from each side to begin to isolate x
-2x = -184
Divide each side by -2 to isolate x
x = -184/-2
x = 92
