Let's just make 15 students a group. how many groups are there if there r 135 student? 135/15 = 9 groups.
so if each group have 4 adults just multiply 9 by 4,
therefore there will be 36.adults.
Answer:
m∠1=118°
m∠2=62°
Step-by-step explanation:
Part A: They are supplementary angles, so
Simplify like terms,
We subtract 92,
Divide by 2,
Part B:
∠
because ∠2 is vertical to 2x+30.
Plug in 44 for x,
∠
Simplify,
∠
∠
° because it is a vertical angle to the 62° angle.
Answer:
24
Step-by-step explanation:
times 6 by 4 and you get 24
Set up two equations.
s + 12 = l , s + l = 74 (these equations represent the problem)
s + (s + 12) = 74 plug in "l" to the second equation.
2s + 12 = 74 combine like terms.
2s + 12 - 12 = 74 - 12 subtract to isolate the variable
2/2s = 62/2 divide to isolate the variable.
s = 31. This means the smaller number is 31.
31 + 12 = 43. since the larger number is 12 more than the smaller, add 12.
l = 43 the larger number has a value of 43.
small number = 31
larger number = 43
hope this helps! :D
541/2 square in I hope this helps
