The 27 red cars make up 60% of the total collection, here is the equation
to be solved:

27 = 60% of C C is the total cars in the collection

27 = .60 C

27 / .60 = C

45 = C

There are 45 cars in the collection

A chemist has 100 g of a 15% saline solution that she wants to strengthen to 29%. The percentage P of salt in the solution by ma
Vinil7 [7]

Answer:

D., x= 19.7 or ≈20. g

Step-by-step explanation:

P(x) = [100(15+x)]/(100+x)

When 0 g additional salt is added, x=0. we have

P(0) = [100(15+0)]/(100+0)= 15

x=0, P=15

We can see this point only on the graph D.

P(x) =29 = [100(15+x)]/(100+x)

29 = [100(15+x)]/(100+x)

29(100+x) = 100(15+x)

2900+29x = 1500+100x

2900-1500=100x-29x

1400 = 71x

x ≈ 19.7 g  or ≈20. g

From the graph D, we can see that to get 29% we need to add ≈ 20 g of salt.

Snow Crest is 11,990.21 feet higher than Mt. Wilson. Write and solve an equation to find the elevation of Mt. Wilson. Let x repr
Nata [24]

Answer:

The elevation of Mt. Wilson is 16,160.10 ft

Step-by-step explanation:

Let

x-----> represent the elevation of Mt. Wilson

y ----> represent the elevation of Snow Crest

we know that

y=x+11,990.21 ----> linear equation that represent this situation

we have that

y=28,150.31 ft ----> see the attached figure

substitute in the linear equation and solve for x

28,150.31=x+11,990.21

x=28,150.31-11,990.21=16,160.10 ft
