How to solve this equation
8(4-x)= 7x+2

Answers

Answer 1

Answer: 8 ( 4 - x ) = 7x + 2
32 - 8x = 7x + 2
      -7x     -7x
--------------------------
32 - 15x = 2
-32           -32
----------------------------
-15x = -30
/-15      /-15

x = 2.

Answer 2

Answer: 8(4-x)=7x+2
32-8x=7x+2
-8x-7x=2-32
-15x=-30
x=-30:(-15)
x=2
answer:x= 2

Answers

Answer:

The statement is true about the point (-1,-2) is the x-coordinate is −1 , the y-coordinate is −2 , and the point lies in the third quadrant.

Step-by-step explanation:

As the point given be (-1,-2) .

As the points always in the form (x,y) .

Thus in points (-1,-2) x-coordinate is -1 and y- coordinate is -2 .

As shown in the graph below the point (-1,-2) is lies in the third quardant .

The x-coordinate is −1−1 , the y-coordinate is −2−2 , and the point lies in the third quadrant.

Keith is racing his little sister Pattie and has given her a 15 foot head start. She runs 5ft/sec and he is chasing at 8ft/sec. For how long can Pattie stay ahead of Keith? Write and solve an inequality and show your work. Plz Help!

Answers

Pattie runs at 5 ft/sec
She has got a head start of 15 feet.
So after 1 second, Pattie runs = (5+15) ft
      = 20 ft
After 2 second Pattie runs = (20+5)ft
   = 25 ft
After 3 second Pattie runs = (25+5) ft
   = 30 ft
After 4 seconds Pattie runs = (30+5) ft
   = 35 ft
After 5 seconds Pattie runs = (35+5) ft
   = 40 ft
After 6 seconds Pattie runs = (40+5) ft
   = 45 ft
Now Keith runs at 8 ft/sec
After 1 second Keith runs = 8 ft
After 2 second Keith runs = (8+8) ft
   = 16 ft
After 3 second Keith runs = (16+8) ft
   = 24 ft
After 4 second Keith runs = (24+8) ft
      = 32 ft
After 5 second Keith runs = (32+8) ft
   = 40 ft
After 6 second Keith runs = (40+8) ft
   = 48 ft
So Pattie will stay ahead of Keith upto 4 seconds. In the 5th second Pattie and Keith will be level and in the 6th second Pattie will be overtaken by Keith.

A project on Kickstarter.com was aiming to raise $15000 for a precision coffee press. They ended up with 714 supporters, raising 557% of their goal. How much did they raise?

Answers

The required solution is $83,550 raised.

It is required to find the amount did they raise.

What is percentage?

A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.

Given:

For a precision coffee press=$15000

Supporters=714

Raised= 557% of their goal.

According to given question we have,

They raise

15000 x 5.57

= $83,550 raised

Therefore, the required solution is $83,550 raised.

For this, we can set up a proportion.
Their aim was 15000, so if they raised 100% of their goal, they wouldve raised exactly 15000.
They raised 557%, so how much did they make?

Proportion:

$15000 100%
$x 557%

Our expression would be x=$15000*557% divided by 100%, which would be $83550, so... a lot of money.

(we did an “x” formation with the proportion, ie “connected” x with 100, and “connected” 15k and 557. The number connecting to x is what we divide the equation by, and the other two are multiplied and then divided by the first number connecting to x. Otherwise we couldve calculated 557% of 15000 and gotten the same result. Whichever way is easier for you :) )
