Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFra

ction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same? because both result in the equation 20 x = 500, which simplifies to x = 25 because both result in the equation 20 x = 500, which simplifies to x = 250 because both result in the equation 10 x = 1,000, which simplifies to x = 10 because both result in the equation 10 x = 1,000, which simplifies to x = 100

Answer:

because both result in the equation 10 x = 1,000, which simplifies to x = 100

Step-by-step explanation:

50 / x = 10/20

Cross product

50 * 20 = x * 10

1000 = 10x

x = 1000 / 10

= 100

10/50 = 20/x

Cross product

10 * x = 50 * 20

10x = 1000

x = 1000/10

= 100

The answer is :

because both result in the equation 10 x = 1,000, which simplifies to x = 100

Angharad had an operation costing $500 She was in hospital for x days The cost of nursing care was $170 for each day she was in
Ket [755]

Answer:

a) Total cost = 500 + 170x

b) 11 days

Step-by-step explanation:

Given:

(a)

Number of days in hospital = x

Cost of operation = $ 500

Cost of nursing per day = $170

∴ Cost of nursing for x days = $ 170x

Therefore, the expression for total cost of her operation and nursing care is given as,

C=500+170x, where C is the total cost.

(b)

Given:

Total cost of operation = C=\$ 2370

Using the expression obtained in (a), we solve for x.

C=500+170x

Plug in 2370 for C and solve for x. This gives,

2370=500+170x\\ 170x=2370-500\\ x=\frac{1870}{170}\\x=11

Therefore, Angharad stayed in hospital for 11 days.

The slope-intercept form of a linear equation is y = mx + b, where x and y are coordinates of an ordered pair, m is the slope of
Serjik [45]
Y = mx + b
y - b = mx
(y - b) / x = m

so its : m = (y - b) / x.....or m = (y/x) - (b/x)

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find
lyudmila [28]

<u>Answer:</u>

f(x)=120000 \times (1.055)^{x}

<u>Step-by-step explanation:</u>

We are given that the present value for the home is $120,000 and the rate of interest is 5.5% i.e. 0.055.

We will use the following formula:

f(x)=P \times (1+r)^{x}

where P is the present value, r is the rate of interest and x is the number of years.

Substituting the values in the above formula to get:

f(x)=120000 \times (1+0.055)^{x}

f ( x ) = 120000 \times ( 1.055 ) ^ { x }
