Answer:
It the 3rd one it's correct cuz i worked it out
Can i have a brainliest please!!:)
Step-by-step explanation:
solve your system by substitution.
c+3d=8;c=4d−6
Rewrite equations:
c=4d−6;c+3d=8
Step: Solve c=4d−6for c:
c=4d−6
Step: Substitute4d−6forcinc+3d=8:
c+3d=8
4d−6+3d=8
7d−6=8(Simplify both sides of the equation)
7d−6+6=8+6(Add 6 to both sides)
7d=14
7d
7
=
14
7
(Divide both sides by 7)
d=2
Step: Substitute2fordinc=4d−6:
c=4d−6
c=(4)(2)−6
c=2(Simplify both sides of the equation)
Answer:
c=2 and d=2
Answer:
5.25 : 1
Step-by-step explanation:
If 84% of the counters are blue, then 16% of the counters are yellow.
percentage of yellow counters = 100% - 84% = 16%
blue counters : yellow counters = 84 : 16 (we don't write %)
Now divide with 16, so the second number becomes 1.
