candace is at a coffee shop and knows she can spend more than $52 before tax she sees this price list in the coffee shop
dimulka [17.4K]

21+7.50p\leq 52

<h2>Explanation:</h2>

For inequalities, "a is no more than b" can be written as:

a\leq b

Here we know Candace that can spend no more than $52 before tax. She can spend a certain amount of money in both Dark Roast coffee and Morning Blend coffee. So she spends:

  • 2 pounds of Morning Blend coffee.
  • p pounds of Dark Roast coffee

Therefore:

<u>Amount of money for Morning Blend coffee:</u>

2\times 10.50=\$21

<u>Amount of money for Dark Roast coffee:</u>

p\times 7.50=\$7.50p

So the total amount of money:

21+7.50p

Finally, the inequality becomes:

21+7.50p\leq 52

Besides, in order to know how many pounds she can spend let's solve for p:

7.50p\leq 52-21 \\ \\ 7.50p\leq 31 \\ \\ p\leq 4.13

So she can spend less that 4.13 pounds.

the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car use
klemol [59]

Answer:

200 litres

Step-by-step explanation:

let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is

g = kd\sqrt{s} ← k is the constant of variation

To find k use g = 25, d = 100 and s = 100, then

25 = k × 100 × \sqrt{100} = k × 100 × 10 = 1000k ( divide both sides by 1000 )

0.025 = k

g = 0.025d\sqrt{s} ← equation of variation

When d = 1000 and s = 64, then

g = 0.025 × 1000 × \sqrt{64} = 0.025 × 1000 × 8 = 200

anygoal [31]
I’ll teach you how to solve 3x-5=-18
—————————————-
3x-5=-18
Move constant to the right-hand side and change its sign:
3x=-18+5
Calculate the sum:
3x=-13
Divide both sides of the equation by 3:
X=-13/3
Your Answer Is x=-13/3
