A postulate is a true statement that does not require to be proved . Also called an axiom.
Answer:
x = 80
Step-by-step explanation:
Let x be the unknown number
1/2 x - 10 = 30
Add 10 to each side
1/2x -10+10 = 30+10
1/2x = 40
Multiply each side by 2
1/2x * 2 = 40*2
x = 80
Answer:
y+(3*8)
Step-by-step explanation:
i think not so good with math
Coordinates of D= (-4,-1)
=> distance from point C to point D is 6 units
Answer:
After 5 hours
Step-by-step explanation:
Given that Rachel can make 3 bracelets in an hour.
Let y be the no of bracelets and x no of hours.
Then equation for Rachael would be y = 3x ... i
Oliver is having initially 5 completed bracelets and every hour he would make 2 new bracelets
Hence equation would be
y = 2x+5 ... ii
Our question is why both will be equal
y would be equal in both if 3x=2x+5
Or x=5
After 5 hours form the start, both will have same number of bracelets.
