19/15

Step-by-step explanation:

=============================================

Work Shown:

y = 4x - 20

4x - 20 = y ...... swap both sides

4x = y + 20 ..... adding 20 to both sides

4x - y = 20 .... subtracting y from both sides

Answer:

TRUE

Step-by-step explanation:

y-4 = 2(x-1)

here, 4 is representing the y value and 1 is representing the x value.

And the slope is 2.

Answer:

damm this looks hella hard

Step-by-step explanation:

Answer:y=-7, x=8

Step-by-step explanation:add two equations together, 4x+-4x and -5y + 8y, and so 3y=-21, and you get y and go on from there, getting the answer.

Answer:

50 minutes (I think)

Step-by-step explanation:

A= 800 - 6m

B = 1000 - 10m

800 - 6m = 1000 - 10m

4m = 200

50 = m

Explanation:

The inequality sign has an "or equal to", which means the boundary line will be solid. We can rule out choices B and C because they have dashed boundary lines.

A solid boundary line means that points on the boundary are part of the solution set.

Now let's see what happens when we plug in a point like (x,y) = (4,0). This will tell us how to shade the blue region.

[tex]-5x + 4y \ge -1 \\\\-5(4) + 4(0) \ge -1 \\\\-20 \ge -1 \\\\[/tex]

This is false because -20 is not larger than -1. It's the other way around.

This tells us the point (4,0) is not in the blue shaded region, and it's not on the boundary line either. We can rule out choice A because of this.

The only thing left is choice D, which is the final answer. I recommend plugging a point from this region into the inequality to confirm we have a true statement.

Answer:

.6 is more than 1/2

.34 is less than 1/2

.812 is more

.9 is more

.099 is less

Step-by-step explanation:

1/2 as a decimal is .5 so anything larger than it will be .51 or greater and anything less will be .49 or less

Answer:

.6 is more than 1/2

.34 is less than 1/2

.812 is more than 1/2

.9 is more than 1/2

0.99 is more than 1/2

Step-by-step explanation: What is 1/2? 0.5. Look at the tenths place. Is the tenth higher than 5 or less than 5? But here is a warning: If you are comparing 1/2 and 1.4, 1.4 is greater than 1/2 because 1/2 is less than 1.

Answer:

Estimation is useful when finding actual products and solving real-world problems because if your actual answer is close or exactly what you had estimated your answer will most likely be correct.

Answer:

We have 200 shirts

Cost $2.80 each

plus a 5% charge for shipping.

Selling price

150% markup

Recall when we use percentages, we need to express them as decimals.

Michelle's cost for each shirt was

2.80 (1.05) = 2.94

The markup is

2.94 (1.50) = 4.41

The markup is added to the cost to get the final selling price.

2.94 + 4.41 = $7.35

Michelle will sell each shirt for $7.35.

Let’s reword the question to make it simpler to understand:

Keeley pays $3.20 per shirt + 5% for shipping.

She sells them at the carnival for 150% the price she paid.

First of all we should work out how much the 5% shipping cost Keeley.

If the shirts are $3.20 that means 10% is $0.32, to get 5% we divide that by 2. This means 5% is $0.16, therefore shipping is $0.16.

The total price Keeley pays per shirt is $3.20 + $0.16 = $3.36.

Now let’s find out 10% of $3.36, which is $0.336, then multiply that by 15 to get 150%:

5.04

Therefore Keeley sells each shirt for $5.04

Answer:

-1=x He messed up on the third step.

Step-by-step explanation:

I worked out the equation and found that when he switched -6x over to -4 he did not change the symbol. So instead of 6+4 he did 4-6. I finished the equation and got -1

Graphs aren't mandatory, but they may help visual learners see why an equation works a certain way. Also, they are a visual tool to quickly find a solution to a problem. Furthermore, they help with presentations to quickly convey an idea to someone (who may not be well versed in mathematics).

For example, if you save $10 a week and already have $50 in a savings account, then the equation you graph is y = 10x+50. Here x is the number of weeks and y is the amount saved.

Now let's say you want to find out how many weeks it would take to have $90 total. You could use guess and check to get the answer. Or you could use algebra and the substitution property. The visual way would be to graph y = 10x+50 and y = 90 together to note how the two lines intersect at (4, 90) to indicate it will take x = 4 weeks to have y = 90 total.

Step-by-step explanation:

first =2* second

second=2*third since the third is half of second

first =2*2*third=4*third

now lets put them all together

first+second+third=224

4*third+2*third+third=224

7*third=224 so the third part is 32

but we need the second piece

2*32=64
