Answer:
0.52
Step-by-step explanation:
The computation of the percentage of the group in which none of the three sports watched is shown below:
= gymnastic percentage + baseball percentage + soccer percentage - gymnastic & baseball percentage - baseball & soccer percentage - gymnastic & soccer percentage + three sports percentage
= 0.28 + 0.29 + 0.19 - 0.14 - 0.12 - 0.18 + 0.08
= 0.48
Now the percentage is
= 1 - 0.48
= 0.52
X + 4x = 75
Combine like terms:
5x = 75
Divide by 5 on each side of the equal sign:
x = 15
Simplify :
12+-5x+6x=4
combine like terms :
-5x+6x=1x
12+1x=4
solving :
12+1x=4
solving for variable ‘x’
move all terms containing x to the left, all other terms to the right, add ‘-12’ to each side of the equation
12+-12+1x=4+-12
combine like terms:
then divide each side
your answer : x=-8
Answer:
for every 5 roses there's 1 plant(s)
Step-by-step explanation:
Answer:
i) 9
ii) 19 pens, 7 pencils, 3 erasers
Step-by-step explanation:
i) 171 = 3² x 19
63 = 3² x 7
27 = 3³
Highest Common Factor/HCF (171, 63, 27) = 3² = 9
Largest no. of bags = 9
ii) In each bag,
No. of pens = 171 / 9 = 19
No. of pencils = 63 / 9 = 7
No. of erasers = 27 / 9 = 3
