Let's make two simultaneous equations and solve. Let's call the smaller number s, and the larger number l
l=3s-1\\l+s=63\\\text{now solve this, and find l and s}\\\text{modifying the second equation}\\l=63-s\\\text{plugging this into the first equation}\\63-s=3s-1\\\text{solve for s}\\64=4s\\s=16\\\text{plug this into the second equation from the original two}\\l+16=63\\\text{solve for l}\\l=47\\\text{gather the answers. The answers are: the larger number is 47, and the smaller number is 16.}

{\color{chartreuse}{Measure\:of\: ∠\:on\: one\: side\:of\:line\:=\:180°}}

∠ Given are (x + 18)° , x° , 4x° and one Angle is 90° as per diagram

Let ,

1st∠ = (x + 18)°

2nd∠ = x°

3rd∠ = 4x°

so ,

⟶\:(x \:+\: 18)°\:+\:x°\:+\: 4x°\:+\:90°\:=\:180°

⟶\:6x°\:+ \:18°\:+\:90°\:=\:180°

⟶\:6x°\:+ \:108°\:=\:180°

⟶\:6x°\:=\:180°\:-\:108°

⟶\:6x\:=\:72°

⟶\:x\:=\:\frac{72}{6} \\

⟶\:x\:=\:12°

substituting x = 12 at the place of x .

= x° + 18°

= 12° + 18 °

1st∠ = 30°

__________________________________

= x°

2nd∠ = 12°

__________________________________

= 4x°

= 4(12)°

3rd∠ = 48°

The value 3.84 is 12% of what number?
xeze [42]
So percent means parts out of 100
so 12%=12/100=1.2/10=0.12/1=0.12

3.84 is 12% of what
'of' means multiply
'is' means = sign

therefor
3.84=0.12 times what
divide both sides by 0.12
32=what

th enumber is 32
