Answers

Answer 1

Answer:

$3.21

Step-by-step explanation:

Answer 2

Answer:

1: $3.21.

2: 50x+120=300

3: h=5/7/ first step would be to adding 7 to both sides.

Step-by-step explanation:

for the 3rd:

you're combining like terms so you have to subtract 7 from both sides you gotta subtract 12-7 so that gives you 5=7h+7-7 and the subtract the 7-7, and that will give you 0 so you have 5=7h left.divide both sides by the same terms (7), so you'll have 5/7 and 7h/7 so 7/7=0 so you drop that and just have the h. now switch sides with the virable and the fraction you still have (5/7)you now have h=5/7.

Help fast Please!!!!! What is the vertical distance between
(-3, -2.5) and (-3, 5)?

Answers

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.

I hope that helps, have a great rest of your day! ^ ^

Here's our data:

15 questions total

Total number of points: 100

Spelling questions are worth 5 and represented by x

Vocab questions are worth 10 and represented by y

Therefore:

x+y=15

5x + 10y= 100

So:

x+y=15

x= 15-y

5x +10y =100

5(15 -y) +10y =100

75 -5y +10y =100

75 +5y = 100

5y=25

y=5

x +y=15

x+5=15

x=10

You ride your bike to school. As you approach an intersection, you decrease your speed by 1.5 miles per hour per second. Select an inequality that represents the time t (in seconds) until your speed decreases by more than 10.5 miles per hour. Then solve the inequality.

Answers

Answer: The acceleration is equal to the change in velocity per time. Now, the acceleration is said to be 1.5 miles/h·s. We are asked to find the corresponding time when the change in velocity is 10.5 miles/h such that the acceleration does not change.

a = Δv/t

1.5 = 10.5/t

t = 7 seconds
