Perimeter = 4×
Where x = 5/7
4* 5/7
p= 20/7
The answer will be a mixed fraction
p= 2 6/7 units
Hope that helps!
Answer: p x 7
Step-by-step explanation:
Number of people times 7 (the amount of money paid)
Answer:
added cement = 200 kg
Step-by-step explanation:
Sand = 0.8*1400
Sand = 1120 kg
If 1120 kg of sand represents the total sand in the 8:2 mixture.
We have to create the equation of the 7:3 mixture as follows.
The sand amount continues the same but the total amount of the mixture and cement will change.
0.7*mixture_mass + 0.3*mixture_mass = mixture_mass
By replacing values, we have:
1120 kg + 0.3*(1400 kg + added cement)= 1400 kg + added cement
added cement = 200kg
<span>it is binomial because you do all that</span>
