Answer:

Z = -4

Step-by-step explanation:

Simplifying

53 = -19z + 5 + 7z

Reorder the terms:

53 = 5 + -19z + 7z

Combine like terms:

-19z + 7z = -12z

53 = 5 + -12z

Solving

53 = 5 + -12z

Move all terms containing z to the left, all other terms to the right.

Add '12z' to each side of the equation.

53 + 12z = 5 + -12z + 12z

Combine like terms:

-12z + 12z = 0

53 + 12z = 5 + 0

53 + 12z = 5

Add '-53' to each side of the equation.

53 + -53 + 12z = 5 + -53

Combine like terms: 53 + -53 = 0

0 + 12z = 5 + -53

12z = 5 + -53

Combine like terms: 5 + -53 = -48

12z = -48

Divide each side by '12'.

z = -4

Simplifying

z = -4

the trailer cost one-fourth as much as the boat. the total cost of both is 4,000 how much did each cost

Katarina [22]

Answer: Boat cost $ 3200

Trailer cost $ 800

Step-by-step explanation: From the statement , the coat of Trailer (t) = 1/4 of the coat of the boat ( b)

i.e t = 1/4b

multiply through by 4

4t = b

both cost 4,000

i.e t + b = 4000

recall: b = 4t

therefore

t + 4t = 4000

5t = 4000

t = 4000/5

t = 800

b = 4000 - 800

b = 3200

A ball is thrown into the air by a baby alien on a planet in the system of Alpha Centauri with a velocity of 43 ft/s. Its height

Lina20 [59]

Answer:

Instantaneous Velocity at t = 1 is 20 feet per second

Step-by-step explanation:

We are given he following information in the question:

$y(t)=43t-23t^{2}$

B) Instantaneous Velocity at t = 1

$y(1) = 43(1)-23(1)^2 = 20$

A) Formula:

Average velocity =

$\displaystyle\frac{\text{Displacement}}{\text{Time}}$

1) 0.01

$y(1 + 0.01)=y(1.01) = 43(1.01)-23(1.01)^{2} = 19.9677\\\\\text{Average Velocity} = \dfrac{y(1.01)-y(1)}{1.01-1} =\dfrac{19.9677-20}{1.01-1}= \dfrac{-0.0323}{0.01} = -3.230000 \text{feet per second}$

2) 0.005 s

$y(1 + 0.005)=y(1.005) = 43(1.005)-23(1.005)^{2} = 19.984425\\\\\text{Average Velocity} = \dfrac{y(1.005)-y(1)}{1.005-1} =\dfrac{19.984425-20}{1.005-1} = -3.1150000 \text{feet per second}$

3) 0.002 s

$y(1 + 0.002)=y(1.002) = 43(1.002)-23(1.002)^{2} = 19.993908\\\\\text{Average Velocity} = \dfrac{y(1.002)-y(1)}{1.002-1} =\dfrac{19.993908-20}{1.002-1} = -3.0460000 \text{feet per second}$

4) 0.001 s

$y(1 + 0.001)=y(1.001) = 43(1.001)-23(1.001)^{2} = 19.996977\\\\\text{Average Velocity} = \dfrac{y(1.001)-y(1)}{1.001-1} =\frac{19.996977-20}{1.001-1} = -3.0230000 \text{feet per second}$

A cake recipe requires 3 1/4 cups of flour for 13 servings and 4 1/2 cups of flour for 18 servings.How much flour is required to

slamgirl [31]

To solve, set up a proportion

3.25 cups x cups
---------------- = ---------------
13 servings 28 servings

Now cross multiply

13x = 28 * 3.25

Simplify.

13x = 91

Divide both sides by 13

x = 7 cups

To check your answer, use proportions again, but change the left side to 4.5 cups over 18 servings, use the same steps, if the answer is the same as above, then the answer is correct
