In the first column you put 40 50 and 60
Then in the 2nd column you put those bombers into the equation (so you would write 3(40)+2 3(50)+2 and 3(60)+2) and then in the third column you solve them (so 3(40)+2=122 3(50)+2=152 3(60)+2=182)

And then you graph them at (40,122) (50,152) and (60,182)

Bethany and Andreas live two blocks apart, and an empty lot lies south of each of their blocks. They both walk diagonally through the empty lots to get to their school, which is about halfway between and 1 block south of their homes. The empty lot that Bethany walks through is 500 feet by 1,200 feet. The empty lot that Andreas walks through is 800 feet by 1,500 feet. How much farther is Andreas' diagonal path than Behany's? *

HELP PLS

Find the hypotenuse of both the lots:

Bethany's lot:500² + b² = 1200² (Simplify)250000 + b² = 1440000 (Isolate b² by subtracting)b² = 1190000 (Take the square root)b = 1090.87Andrea's lot:800² + b² = 1500² (Simplify)640000 + b² = 2250000 (Isolate b² by subtracting)b² = 1610000 (Take the square root)b = 1268.86

Subtract: 1268.86 - 1090.87 = 177.99 ft.

SHOW ALL WORK AND THE CHECK TO GET BRAINLIEST NO LINKS

Answers

Answer:

a=16

Step-by-step explanation:

First of all you subtract both sides by 2 which makes 6-2=a/4 +2-2 which makes 4=a/4. then you multiply both sides by 4,  4x4=a/4 x 4 which makes a= 16 now you check this by putting a into the equation then going 16/4=4 then adding 2,  4+2= 6 then checking if it equals which it does

Would be amazing if you marked brainliest :)

Answer:

a = 16. both solve and check are below.

Step-by-step explanation:

6 = a/4 + 2 is the equation given.

you have to isolate the a/4, which is by cancelling out the 2. we cancel the 2 out by subtracting 2 from both sides.

6 - 2 = a/4 + 2-2

you get the equation now:

4 = a/4

isolate a by doing the inverse operation that it is currently in. in this case, the operation they use is division. so inverse of it would be multiplication.

4*4 = a/4*4

a = 16

──────────────────

if you want to check it, you plug in a with 16 and use the PEMDAS method.

6 = 16/4 + 2

6 = 4 + 2

the equation is true, thus in a is equal to 16.

A person travels 7 miles in 3 ½ hours, how many miles will he travel in ¼ hour?

Answers

Answer:

1.6 miles

Step-by-step explanation:

Example 1

It took Markus half an hour to drive home from work.  He averaged 34 miles per hour.  How far does Markus live from his work?

Solution

We are given that it takes 1/2 an hour for the trip.  This is a time:

       t  =  1/2

We are given that he averages 34 miles per hour.  This is a rate:

       r  =  34

We are asked how few he has traveled.  This is a distance.  We use the d=rt equation:

       d  =  rt  

           =  (34)(1/2)

           =  17

Markus lives 17 miles from work.

Now try one by yourself.  If you want to see the answer, put your mouse on the yellow rectangle and the answer will appear.

It's Number Line B. All symbols are supposed to be less than or equal to, just don't have that symbol on my keyboard.

Answer:

B

Step-by-step explanation:

2x-6 is [tex]\leq[/tex] 2 is what you start with and first, you would have to move the 6 to the other side to isolate the 2x. To do that, you do the opposite operation of the 6 which is addition. Add 6 to both sides to the eqaution would end up being 2x[tex]\leq[/tex]8. Now to isolate the x, we also have to do the opposite operation so divide the 2x and the 8 by 2. The eqaution would look like this x [tex]\leq[/tex]4. Number line B would show this ineqaulity as the arrow is going left to show that x is less than 4 but the dot is also shaded in which means that 4 can also be the answer as well. Hope this helps:)
