Step-by-step explanation:

Let the common multiplier of the given ratios be x.

Therefore, no. of roses = 7x & no. of carnations = 5x

According to the given information:

$7x + 5x = 96 \\ \\ \therefore \: 12x = 96 \\ \\ \therefore \: x = \frac{96}{12} \\ \\ \therefore \: x = 8 \\ \\ \therefore \: 7x = 7\times 8 = 56 \\ \& \: 5x = 5 \times 8 = 40 \\$

Thus,

Number of roses = 56

Number of carnations = 40

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.

A student is solving the equation 10x−3+2x=6(x−3). Which describes a first step the student could use to solve the equation corr

Arisa [49]

Students can combine like terms on the left side of the equation, resulting in 12x−3=6(x−3).

Given the equation solved by a student

10x−3+2x=6(x−3)

The first step that the student could use to solve the expression correctly is to expand the bracket on the right-hand side of the equation using the distributive law as shown:

$10x-3+2x=6(x-3)\\10x-3+2x=6x - 6(3)\\10x-3+2x=6x - 18\\$
