Mathematics
1 answer:
Aleksandr [31]4 years ago
8 0

Answer:

a) 3 people will need 35 days to paint the bridge

b) p=105/t

Step-by-step explanation:

a)

We have 7 people each one is to work 15 days, so the bridge needs a total of 7(15) days of work

7(15)=105

Then we have 3 people each one is to work t days, altogether should do a total of 105 days of work

3(t)=105

Solve for t

t=35

b)

Substitute p for 3 in the second equation

p(t)=105

Solve for p

p=105/t

4y + 4 = 2y - 10 <br> can somebody break this down to solve it ? please
vredina [299]

Answer:

y=-7

Step-by-step explanation:

first, you want variables on one side, numbers on the other side of the equation.

4y+4=2y-10

*plus ten on both side to get rid of -10*

4y+14=2y

*minus 4y on each side to get rid of 4y*

14=-2y

*divide by -2 on each side to get the value of just one y itself*

y=-7
