If you turn the D into the 100 and the w into 50 take away 50 from the 100 then add it to the 2,340 and you should get $2,390.

How can you compare prices at two different stores by finding the constant of proportionality
dimaraw [331]

Answer:

The constant of proportionality gives you the price per unit at each store.

Step-by-step explanation:

If you assume that the price (y) is directly proportional to the amount (x) you get, the formula is

y = kx

where k is the constant of proportionality.

k = y/x

k has the units of cost per unit, for example, dollars per ounce.

The fewer the dollars per ounce, the better the deal you are getting.

If store A offers apple sauce at $1.29 for 25 oz and Store B offers apple sauce at $2.89 for 50 oz, which is the better deal?

At store A, k = $1.29/25 oz = $0.052/oz or 5.2¢/oz

At store B, k = $2.89/50 oz = $0.058/oz or 5.8¢/oz

The apple sauce is cheaper at Store A.

What best describes the number 5? write prime, composite, neither prime nor composite, or both.
Wewaii [24]
<span>Prime is the best option describes the number 5.The number 5 is a prime because prime can be divided evenly by 1, or itself. And it must be a whole number greater than 1.But 6 can be divided evenly by 1, 2, 3 and 6 so it is NOT a prime number (it is a composite number).</span>

anastassius [24]
Two whole numbers will end up like this: 8x8=64,but multiplying a whole and a decimal will end up like this 8x8.1=64.1
or 8x8=8 to the second power.
this should be sufficient information.

Hi how do I solve this simultaneous equation
WITCHER [35]

Answer:

M (-3, -5/2)

N (3, -1)

Step-by-step explanation:

Solve the first equation for x.

4y = x − 7

x = 4y + 7

Substitute into the second equation.

x² + xy = 4 + 2y²

(4y + 7)² + (4y + 7)y = 4 + 2y²

Simplify.

16y² + 56y + 49 + 4y² + 7y = 4 + 2y²

18y² + 63y + 45 = 0

2y² + 7y + 5 = 0

Factor.

(y + 1) (2y + 5) = 0

y = -1 or -5/2

Plug back into the first equation to find x.

x = 4(-1) + 7 = 3

x = 4(-5/2) + 7 = -3

M (-3, -5/2)

N (3, -1)
