Answer: I'm pretty sure its 78.

Step-by-step explanation:

27 x 1.5 = 18

52 x 1.5 = 78

Answer:

x = 78

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{OD}{AP}$ = $\frac{DT}{PN}$ , substitute values

$\frac{27}{18}$ = $\frac{x}{52}$ ( cross- multiply )

18x = 1404 ( divide both sides by 18 )

x = 78

If two boxes of cereal and a jug of milk cost $8.50, and three boxes of cereal and two jugs of milk cost $14.00, how much does a

Citrus2011 [14]

Answer:

Step-by-step explanation:

Let c represent the cost of a box of cereal and let m represent the cost of a jug of milk.

Create a system of equations:

2c + m = 8.5

3c + 2m = 14

Solve by elimination by multiplying the top equation by -2:

-4c - 2m = -17

3c + 2m = 14

Add them together and solve for c:

-c = -3

c = 3

So, a box of cereal costs $3

The total stopping distance T for a vehicle is T = 2.5x + 0.5x 2 , where T is in feet and x is the speed in miles per hour. Appr

Kobotan [32]

Answer:

% change in stopping distance = 7.34 %

Step-by-step explanation:

The stooping distance is given by

$T = 2.5 x + 0.5 x^{2}$

We will approximate this distance using the relation

$f (x + dx) = f (x)+ f' (x)dx$

dx = 26 - 25 = 1

T' = 2.5 + x

Therefore

$f(x)+f'(x)dx = 2.5x+ 0.5x^{2} + 2.5 +x$

This is the stopping distance at x = 25

Put x = 25 in above equation

2.5 × (25) + 0.5× $25^{2}$ + 2.5 + 25 = 402.5 ft

Stopping distance at x = 25

T(25) = 2.5 × (25) + 0.5 × $25^{2}$

T(25) = 375 ft

Therefore approximate change in stopping distance = 402.5 - 375 = 27.5 ft

% change in stopping distance = $\frac{27.5}{375}$ × 100

% change in stopping distance = 7.34 %

What is the answer to 3/x=-3/3x+5

Aleonysh [2.5K]

Answer:

$-\frac{5}{4} =x$

Step-by-step explanation:

We first need to bring x up into the numerator. I will find common denominators by multiplying both sides by each denominator.

$\frac{x(3x+5)}{1} *\frac{3}{x} =\frac{-3}{3x+5}*\frac{x(3x+5)}{1}$

This will eliminate both denominators and leave me with

$(3x+5)3=-3(x)\\9x+15=-3x$ after I simplify the parenthesis.

Now I will solve the equation for x by subtracting 9x from both sides.

$9x-9x+15=-3x-9x\\15=-12x$

Then divide by the coefficient of x.

$\frac{15}{-12}=\frac{-12x}{-12}$

$-\frac{5}{4} =x$
