1. 2a=9b first we will divide the both sides with parameter b and get
2(a/b)=9 now we will divide both sides with number 2 and get
a/b=9/2 => a : b = 9 : 2
2. 6a-3b=5b first we will add to both sides number (+3) and get
6a=5b+3b => 6a=8b then divide the both sides with parameter b and get
6(a/b)=8 now we will divide the both sides with number 6 and get
a/b=8/6 if we simplify the fraction we get
a/b=4/3 => a : b = 4 : 3
3. a+b=3b we will add to the both sides parameter (-b) and get
a=3b-b => a=2b then divide the both sides with parameter b and get
a/b=2 => a/b=2/1 => a : b = 2 : 1
4. a/5=b/7 first we will divide the both sides with paremeter b and get
a/(5b)=1/7 now we will multiply the both sides with number 5 and get
a/b=5/7 => a : b = 5 : 7
Good luck!!!
Answer:
y = 7
Step-by-step explanation:
The diagonals of a rectangle are congruent and bisect each other, then
AC = BD , that is
AE + EC = BD [ AE = EC = 6y ]
6y + 6y = 84
12y = 84 ( divide both sides by 12 )
y = 7
Answer:
c
Step-by-step explanation:
m<4 and m<3 is a straight angle. straight angles are equal to 180 degrees. the friend found m<3=40 and m<4 is equal to 140 degrees (im not good at explaining, sorry)
Mia tossed a penny,a nickel and a dime all possible outcomes of H is the answer C.
Step-by-step explanation:
- The two possible outcomes for penny,nickel and dime is H & T.
- H is for head T is for tail.
- Let A {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}
- Tossing a fair coin will give the above result.
- S is the called the n number of outcomes that are available for a set.
- Total outcome of Sample space 8.
- The three diagram is like a game theory it exploits different outcome.
Answer: 5.6
===================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(B) = AB/BC
cos(62) = AB/12
12*cos(62) = AB
AB = 12*cos(62)
AB = 5.63365875
AB = 5.6
