What value is true of x makes this equation true 0.7x-5=0.2x+1

Answers

Answer:

x=12

Step-by-step explanation:

First you make sure x is on both sides of the equation. So you do 0.7x-5-0.2x=0.2x+1-0.2x. Which just simplifies to 0.5x-5=1. You make sure x is the only thing on that side of the equation so you do 0.5x-5+5=1+5 which simplifies to 0.5x=6. Multiply the equation times 2 to just have x. x=12. The value that makes true of x is 12.

Step-by-step explanation:

Distribute:

7*w =7w

7*3=21

so now you have 7w+21

Divide:

now you would divide 21 and 7w by 7, the 7 would get canceled out, so you are left with 21/7 which equals 3

Find the slope intercept equation of the line

PLEASE SOMEONE HELP WHO UNDERSTANDS HOW TO DO THESE BECAUSE I KEEP GETTING THE WRONG ANSWER!!!

Answers

Step-by-step explanation:

For every 3 blocks across, the line graph goes up by 2 blocks. Therefore the slope of the line is 2/3.

The line also intercepts the y-axis at -3.

Hence the slope-intercept form is y = 2/3 x - 3.

When doing slope I suggest using slope triangles:) make a dot at -3, then go to the right 3 spaces, from this point go up 2 spaces and make another dot. Do that for as long as you need your line to be:) When you go up 2 spaces use that last dot and go over 3 spaces and up 2. Keep repeating

tarts.
A. $4.3
B. $7.7
C. $9.84
D. $13
​

Answers

Answer: $8.60

Step-by-step explanation:

Let the price of a bread = x

Let the price of a tarts = x - 1

If 3 times the price of a loaf of bread is $29.5 more than half of the price of a box of tarts. This can be represented as:

3 × x = 1/2 × (1 - x) + 29.5

3x = 0.5 - 0.5x + 29.5

3x + 0.5x = 29.5 + 0.5

3.5x = 30

x = 30/3.5

x = 8.6

A square has a area of 4m^2. What is the length of each side?

Answers

Answer: If by m you mean meters and not a variable, then you get 4 for the length of the sides. If you mean m as a variable, then the answer is 2m

Step-by-step explanation: First simplify the equation by squaring 4. This gives you the area, which is 16. Then take the square root of 16 to get the area, which is 4. If m is a variable in the equation then you must take the square root of  (4m^2) and the answer you get for the side length you get is 2m

yards. What is the percentage decrease

Answers

20.4873901955% decrease
3529-2806=723
(723/35290)x100= 20.4873901955

First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.

Answer:

59.02%

Step-by-step explanation:

SO SORRY THAT THIS IS LATE anyway what you is minus the biggest number by the smallest number which would be 3,529 - 2,806 = 723

BECAUSE 3,529 is the original number you would do 723 / 3,529 = 0.5902521

then you would times that number by 100

0.5902521 x 100 = 59.02%

Movie tickets cost $6 for adults and $2 for children under the age of 12. If 175 movie tickets were sold with cash receipts of $750, how many children’s tickets were sold?

Answers

Answer:

75 child tickets and 100 adult tickets were sold.

Step-by-step explanation:

Given that adult tickets cost $ 6 and children's tickets cost $ 2, knowing that 175 tickets were sold for $ 750, to determine how many child tickets were sold the following calculation must be performed:

2 x 175 = 350

750 - 350 = 400

6 - 2 = 4

400/4 = 100

175 - 100 = 75

100 x 6 = 600

75 x 2 = 150

Therefore, 75 child tickets and 100 adult tickets were sold.
