What Did They Do Wrong? If U Dont Know Dont Answer And If Ur Right Ill Give U Brainliest

Answers

Answer 1

They subtracted 5 on both sides of the equation. They were suppose to add 5 on both sides of the equation for it to cancel out each other. If you need any further explanation, please ask me :)

Correct version:

5y + (-5) = 10

       +5     +5    add 5 to both sides, 5's will cancel out on left side.

___________

5y     15

__ = __        divide 5 on both sides, 5's will cancel out on left side.

5      5

y = 3, final answer

Answer 2

Answer:

its the first part the (-5) -5  is supposed to be (-5) +5

Step-by-step explanation:

so the equation is 5y=15

then you divide 5y/5 is y so then you 15/5 is 3

so the answer is y=3

I need the value of x. 10x + 4 - 2x = 6x + 9 + 7

Answers

Answer:

x = 6

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10x+4−2x=6x+9+7

10x+4+−2x=6x+9+7

(10x+−2x)+(4)=(6x)+(9+7)(Combine Like Terms)

8x+4=6x+16

8x+4=6x+16

Step 2: Subtract 6x from both sides.

8x+4−6x=6x+16−6x

2x+4=16

Step 3: Subtract 4 from both sides.

2x+4−4=16−4

2x=12

Step 4: Divide both sides by 2.

2x=12

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50. Let SSS represent the number of stacks of pancakes that Benjamin buys.

Answers

Answer:

4 stacks of packages

4 * 4 = 16 pieces of pancake

Step-by-step explanation:

Maximum amount to spend ≤ $30

Milk chocolate = $3.25

Pancakes per stack = 5.50 (sold in stacks of 4)

Let number of stacks = s

In equality terms :

3.25 + 5.50s ≤ 30

5.50s ≤ 30 - 3.25

5.50s ≤ 26.75

s ≤ 26.75 / 5.50

s ≤ 4.86

Hence, 4 stacks of pancakes can be purchased

Answer:

3.25+5.50S<30

Step-by-step explanation:

Benjamin can afford at most 16 pancakes

Jennifer buys 4.25 pounds of gummy worms for $2.96 per pound and 0.5 pounds of jaw
breakers for $4.95 per pound. Jennifer gives the clerk $20.00. If there is no sales tax on these
items, how much change should she receive?
In money form!

Answers

Answer:

$4.94

Step-by-step explanation:

Gummy worms cost $2.96 per lb, and she bought 4.25 lbs, so:

2.96 * 4.25 = $12.58 spent in gummy worms

Jaw breakers cost $4.95 per lb, and she bought 0.5 lbs, so:

4.95 * 0.5 = $2.48 spent in jaw breakers

Adding the gummy worms and the jaw breakers, she spent:

12.58 + 2.48 = 15.06 in Total

She gave the clerk $20.00, but she only spent only $15.06, so the clerk gave her back the difference:

20 - 15.06 = $4.94 is the change that she received

Describe what it means for something to be continuous.

Answers

Answer:

a continuous function is a function that does not have any abrupt changes in value, known as discontinuities. If not continuous, a function is said to be discontinuous.

Step-by-step explanation:

got me a 100 in the journal activity

A function is continuous if the graph of function is an unbroken curve; that is, the graph has no holes, gaps, or breaks.

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

To describe means for something to be continuous.

Now, We know that;

A function is continuous at a point, if it must be defined at that point, its limit must exist at the point, and the value of the function at that point must equal the value of the limit at that point.

Thus, A function is continuous if the graph of function is an unbroken curve; that is, the graph has no holes, gaps, or breaks.
