19. 9a2b = c + 4a, for a

Mathematics
1 answer:
xenn [34]2 years ago
5 0

Answer:x/5 + 2b/5

Step-by-step explanation:

9a-2b=c+4a solve for a

9a-2b=c+4a

add -4a to both sides

9a-4a-2b=x+4a-4a

5a-2b=x

add 2b to both sides

5a-2b+2b=x+2b

5a= x+2b

divide by 5

5a/5 = x/5 +2b/5

a= x/5 + 2b/5

Shane and abha earned a team budget that required their team to collect no less than 2000 cans for recycling. Abha collected 178
TiliK225 [7]

Answer:

s ≥ 911

Step-by-step explanation:

Let

s = number of cans Shane could collect

Abha collected 178 more cans than Shane did.

Abha = s + 178

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for recycling

Number of cans collected by Shane + number of cans collected by Abha ≥ 2000

s + 178 + s ≥ 2000

2s + 178 ≥ 2000

2s ≥ 2000 - 178

2s ≥ 1,822

Divide both sides by 2

s ≥ 1,822 / 2

s ≥ 911

Mrs. Madison's class recorded how many students had various types of pets. Twice the number of students who own a lizard is less
ss7ja [257]
So twice the number of students who own a lizard is represented by 2l where l is the number who own a lizard. we are given this is less than 10 so 2l<10 we can solve for l by dividing both sides by 2 to get l<5 meaning the number of students who own a lizard is less than 5

Number of people can hold in each car = 10

Solution:

Number of cars in the Blazing Bullet = 6

Total number of people can ride at one time = 60

Number of people can hold at one Bullet car = ?

Let n be the number of people in each car can hold.

Now write a equation to find the number of people in each car.

Number of cars × number of people in each car = Total number of people

⇒ 6 × n = 60

⇒ 6n = 60

Now, solving this equation.

⇒ 6n = 60

Divide both sides of the equation by 6.

$ \Rightarrow\frac{6n}{6} = \frac{60}{6}

$ \Rightarrow n=10

⇒ n = 10

Hence 10 people can hold in each car.
