Enter the value of x that makes the given equation true.

3(5 - x) = 7x - 2​

Answers

Answer 1

Answer:

exact form: x=17/10

Decimal form: x=1.7

mixed number form: 1 7/10

Answer 2

Answer:

x = 17/10 (as a fraction) or x = 1.7(as a decimal) or x = 1 7/10(as a mixed number)

Step-by-step explanation:

3(5-x) = 7x - 2

3 * 5 - 3* x = 7x - 2 (brackets means multiply)

15 - 3x = 7x - 2 (when over equal sign negative changed to positive)

15 + 2 = 7x + 3x

17/10 = 10x/10 (cross-cancel cuz u tryna isolate the x)

17/10 = x

Answers

Answer:

2x+2y-2

Step-by-step explanation:

3x+2y+2-X-4

So 3x minus 1x is 2x. Hence:

2x+2y+2-4

Then: 2-4=-2. Hence:

2x+2y-2

The variables x and y cannot be put together. Hence, this is your final answer.

} V
m =
25W + 20
After how many weeks will Kevin and Hannah have the same amount of money
saved?

Answers

Answer:

2 weeks

Step-by-step explanation:

If you sum up their savings twice you will have the same amount

16 + 47=79 for week 1. 20 + 25=70 for week 1.

79 + 16=95 for week 2. 70 + 25=95 for week 2.

Explain how you would distribute 4 ones into 5 groups.m​

Answers

The number of ways he can distribute 4 ones into 5 groups is 120 ways.

Permutation

Permutation has to do with the arrangement. For instance, to distribute "r" values into "n" groups, this can be calculated as:

nPr = n!/(n-r)!

Hence for you to distribute 4 ones into 5 groups, we will use the formula above to have:

5P4 = 5!/(5-4)!

5P4 = 5!/1!

5P4 = 5!

5P4 =120 ways

Hence the number of ways he can distribute 4 ones into 5 groups is 120 ways.

Compare a dilation to the other transformations:
translation, reflection, rotation.

Answers

Answer:

A translation simply moves the graph, or pre-image, without changing the size or spinning the image. A reflection flips the pre-image across some line. A rotation spins the pre-image around a point. A dilation either expands or shrinks the pre-image.

Step-by-step explanation:

Hope this helps

Transformation involves changing the size, the position and the location of a shape.

Dilation

When a shape is dilated, the size of the shape is altered to form a new shape

Translation

When a shape is translated, the shape is moved across the coordinates, but the size remains unchanged

Reflection

When a shape is reflected, the shape is flipped across the coordinates, but the size remains unchanged

Rotation

When a shape is rotated, it must be rotated across a point, and the size remains unchanged

The above means that translation, reflection and rotation are rigid transformation, while dilation is not.

A school has 1,200 concert tickets for sale. Some of the
tickets are for reserved seats (r), and the rest are for general
admission (g). At most, 500 reserved-seat tickets can be
sold. Which pair of inequalities models the number of
tickets that can be sold?

Answers

Answer: d

Step-by-step explanation:

r+g less than or equal to 1,200

r less than or equal to 500

The pair of inequalities models the number of  tickets that can be sold is r + g ≤ 1200 and r ≤ 500

Let r represent the number of reserved seats and g represent the number of seats for general  admission.

Since the school has 1,200 concert tickets for sale, hence:

r + g ≤ 1200   (1)

Also, there are at most 500 reserved-seat tickets. Hence:

r ≤ 500  (2)

The pair of inequalities models the number of  tickets that can be sold is r + g ≤ 1200 and r ≤ 500

URGENT need answer quick

Answers

Answer:

Part A: x = 4.

Part B: The answer normally would be x = 12, but since your question asked why it has no real solution, it is because the solution (x=12) does not make the equaion true. Why? Because the value given from the equation that should make the equation true does not relate the equation in itself; hence making it have no solution.

Chelsea went to Starbucks to get coffee for her and her friends she bought two pumpkin spice lattes for $4.50 each an iced vanilla latte for $4.20 and a cake pop for $2.80. If she wants to leave a 10% tip for the barista how much will she pay in total?

Answers

YOUR ANSWER IS : $17.60

Because—— she first bought 2 pumpkin slice lattes for 4.50 EACH so that would be 4.50 time 2, then you would add another 4.20. And finally add another 2.80. After you add all those numbers you will have $16. But you need to find a 10% tip. So divide the total (16 in this case) by 100. After doing this you will have 1% of your total. But you need 10% so you will get that 1 percent (0.16) and multiply it by 10. You will then get $1.6. So you now will add $16 and
