Answer:
top one =75
bottom one=65
Step-by-step explanation:
all angles should equal to 180
so 180-40=140
the sum of th eother two angles will be 140
so 4x-5+3x+5=140
now solve for x
x=20
subsitute for x
4(20)-5=75
3(20)+5=65

Answer:
There are 20 kids total in the class.
Step-by-step explanation:
15/100 × 20 = 3
You can use direct proportion for any percent calculation.
Compare each number with its percent.
3 i
s 15
% of what number? Let the number be x
So, 3 represents 15
% and x represents 100
%
x/
100
= 3/15
Multiply by 100 to isolate x
x =
x = 20
Check: 15/
100 × 20 = 3
Answer:
$1.92
Step-by-step explanation:
24 x 8/100 = 1.92
Answer:
x = 2, x = -6
Step-by-step explanation:
Subtract 8 from both sides.
Simplify.
Solve with quadratic formula.
a = 1
b = 4
c = -12
I do not have time to show work for quadratic formula parts.
I am so sorry for this inconvenience.
