15. +2

Step-by-step explanation:

When multiplying integers:

two negatives = positive

two positives = positive

one negative x one positive = negative

So, if the signs are the same, the answer is positive.

If you have two different signs, the answer is negative.

You multiply the integers like normal.

Anything multiplied by zero = 0.

Anything multiplied by one = itself (just be careful of the sign).

The gas tank in Sharon’s car can hold up to 16.5 gal of gas. About how many liters of gas can the tank hold? 1 L≈1.06 qt
Andreas93 [3]

we know that


a) 1 gallon is equal to 4 quarter of gallon

so

by proportion

16.5 gallons is equal to

\frac{1}{4} =\frac{16.5}{x} \\ x=16.5*4\\ x=66quarter of gallon


b) 1 liter is equal to 1.06 quarter of gallon

by proportion

66quarter of gallon is equal to

\frac{1}{1.06} =\frac{x}{66} \\ x=\frac{66}{1.06} \\ x=62.26\\ x=62.3liters


therefore


the answer is the option

62.3L

An athletic club buys car magnets and pom-poms for club members. The car magnets cost 4.95 each, and pom-poms cost each. The ath
VLD [36.1K]

Answer:

Each car magnet costs $4.95 and each pom-pom costs $0.425

The club spent $495 on 100 car magnets and $85 on 200 pom-poms.

Step-by-step explanation:

I guess that we have to calculate the price of pom-poms and how much money was spent purchasing car magnets and pom-poms.

x + y = 300

2x = y (now we replace y)

x + 2x = 300

3x = 300

x = 100

The club purchased 100 car magnets and 200 pom-poms.

To determine the price of each pom-pom:

($4.95 x 100) + 200P = $580

$495 + 200P = $580

200P = $85

P = $0.425

Please hurry!! the graph of y= 2/x - 1 is shown which statement about the graph is accurate
NemiM [27]

Answer:

B. The graph has no y-intercepts

Step-by-step explanation:

We see that we have vertical and horizontal asymptotes.

We also see that the right side of the graph has an x-intercept of (2, 0).

Therefore, A and D are incorrect.

We use the vertical asymptote x = 0 to get our answer B, as we will never cross the y-axis as x approaches negative and positive infinity.
