Answer:

Alexa lost 16 points overall

Step-by-step explanation:

To determine whether Alexa had a net receipt or loss of points, we will fine the total points received or lost, and find the difference:

points lost:

3 point for each of the 7 questions she answered wrong

lost point = 3 × 7 - 21 points

Points received:

5 points for answering a bonus question

point received = 5 point

The points lost (21) is greater than the points received (5), hence, there was a net loss. The net loss is calculated as follows:

points lost - points received

= 21 - 5 = 16

∴ Alexa lost 16 points overall

The balance on George's checking account is $48.

Step-by-step explanation:

To find the balance on George's checking account after writing the checks, you have to take the initial balance and add the amount he got paid and subtract the amounts of the checks he wrote:

Checking account balance=$127+$130-$167-$42

Checking account balance=$48

According to this, the answer is that the balance on George's checking account is $48.

Answer:

119 calories in a serving

Step-by-step explanation:

>>1 gram of carbs=4 cal

20 g of carbs times 4 calories per gram of carbs= 80 calories

>>1 gram of fat=9 calories

3 g of fat times 9 calories per gram of fat= 27 calories

>>1 gram of protein=4 calories

3 g of protein times 4 calories per gram of protein= 12 calories

<80+27+12=119 calories total in a serving of chips>

Answer: C is no and the others are yes.

Step-by-step explanation:

Answer:

the number of tickets remaining is inversely proportional to the time in minutes:

number of tickets remaining  = total amount of tickets - (25 tickets sold per minute x time in minutes) = 350 - 25T

Step-by-step explanation:

for example:

after 5 minutes, the number of tickets remaining = 350 - (25 x 5) = 225 tickets

after 10 minutes, the number of tickets remaining = 350 - (25 x 10) = 100 tickets

after 14 minutes, the number of tickets remaining = 350 - (25 x 145) = 0 tickets

Well the numbers are right, but not the order.

First the x-intercept is (-7,0) not (0,-7) ---- It's (x,y) though ---------

Second the y-intercept is (0,2) not (2,0)

You got them swapped but the numbers are correct anyway.

Answer:

980 km.

Step-by-step explanation:

The speed of the car is constant,

From the double number line:

When the time is 0 hour, the distance covered is 0 km.

When the time is 1 hour, the distance covered is 70 km.

When the time is 2 hours, the distance covered is 140 km,

which can be written as

when the time is 2 hours, the distance covered is 70 x 2 km.

Similarly,

When the time is 3 hours, the distance covered is 210= 70 x 3 km.

This can be generalized as,

When the time is n hours, the distance covered is  70 x n km, i.e

The distance traveled in n hours = 70 x n km.

So, for 14 hours, n= 14,

Hence, the distance traveled in 14 hours = 70 x 14= 980 km.
