set up and solve a system of equations to solve the problem The school band sells carnations on Valentine's Day for $3 each. It

sasho [114]

Answer:

Number of carnations = 6

Step-by-step explanation:

Let the number of carnations school band buys from florist be x.

Cost of each carnation = $0.50

Total cost for x number of carnations = $0.50x

Also , delivery cost = $15

So, total cost on buying x number of carnations from florist = 0.50x + 15

Now,

School band sells carnations at a price of $3 each.

Total revenue they get get after selling x number of carnations = $3x

We need to find that , when will the cost of the carnations be equal to the revenue from selling them.

i.e 3x = 0.50x + 15

or 3x - 0.50x = 15

or 2.50x = 15

or x = $\frac{15}{2.50}$

or x = 6

so on selling 6 carnations cost of carnation reach to the point where it is equal to revenue

Divide £52 in the ratio 11:2

True [87]

First, get the sum of the ratio. (11 + 2 = 13)

Divide 52 by 13 to find one 'part' of the ratio. (52 ÷ 13 = 4)

Now that we have one 'part' of the ratio, we multiply it by 11 and 2 to get: (£4 × 11 = £44) and (£4 × 2 = £8).

The ratio will be £44:8.

We can check if this is correct by adding 44 and 8 to see if it adds up to 52. (44 + 8 = 52). It does, so it's correct.

5. Express log2 6 + log2 7 as a single logarithm.

denis-greek [22]

When making two logarithms one logarithm you keep the base (in this case that would be 2) and multiply the two numbers (in this case 7 times 6 = 42) so the answer is

log(2) 42
