Hey, sorry this took so long for you to get an answer. Let me try.

Answers:

Part A: Answer choice C.

Part B: 6 people can come to the bowling alley.

Explanation:

For Part A, I've concluded that the answer is C. Ben can't spend more than $80, so it has to be equal to or less than 80. The flat fee is $45, and the cost per person is variable, $5.50p, so I combined all of those together and got 45+5.50p ≤ 80 .

This is answer choice C.

And for Part B, I got 6. I got this answer from doing 80, the maximum cost, minus the flat rate, 45. Then, I divided this number by 5.50 to get the number of friends that could be paid for.  I originally got 6.3636... but I rounded down because you can't have 0.3636... of a friend to come to the bowling alley.

Hopefully this isn't too late. Good luck.

The answer will be c

Answers

Answer:Group of answer choices

Step-by-step explanation:

What you first want to do is like and unlike terms so basically liketerms are terms withthe same sign and unlike terms are terms with diferent signs for instinse 3g and 2g are like terms so -33 and -9 and -9 and 9 are unlike terms so you just have to find the like and unlike terms to answer the question!

Answer: -9

Step-by-step explanation: Let's solve your equation step-by-step.

3g+15−12+3−2g+4=1

Step 1: Simplify both sides of the equation.

3g+15−12+3−2g+4=1

3g+15+−12+3+−2g+4=1

(3g+−2g)+(15+−12+3+4)=1 (Combine Like Terms)

g+10=1

g+10=1

Step 2: Subtract 10 from both sides.

g+10−10=1−10

g=−9

So the answer is g=-9

Step-by-step explanation:

195+1800=1995

Answer:

1,955 miles

Step-by-step explanation:

For this problem all we have to do is, assuming they were constantly going that speed and never stopped, multiply the items and the mph.

SO, to the airport is 65mph*3 hours, which would give 195 miles.

Then, To their destination, 450mph * 4hours = 1,800 miles

Now all that is left to do is add

195 + 1,800 = 1,995

1,995 miles

P.S I TRIED MY BEST

Step-by-step explanation:

The required values of ratios are 9/16,3/2, 7/6 and 1/12 respectively. The only false option is (c).

What is the application ratio and proportion?

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

All the options are examined one by one as follows,

(a) The ratio of 5/8 to 10/9 is given as,

5/8 : 10/9

= (5/8) ÷ (10/9)

= 5/8 × 9/10

= 9/16

Thus, it is true.

(b) The ratio of  4/7 ∶ 8/21 is given as,

4/7 ∶ 8/21

= (4/7) ÷ (8/21)

= 4/7 × 21/8

= 3/2

Thus, it is true.

(c) The unit rate of 7/9 and 2/3 equivalent to the ratio given below,

7/9 : 2/3

= 7/9 ÷ 2/3

= 7/9 × 3/2

= 7/6

Thus, it is false.

(d) The unit rate of 9/16 and 27/4 equivalent to the ratio given below,

9/16 : 27/4

= 9/16 ÷ 27/4

= 9/16 × 4/27

= 1/12

Thus, it is true.

Hence, the ratios for the given options are obtained as 9/16,3/2, 7/6 and 1/12 respectively.

Write and solve an equation to show the answer.


Explain when to use division and when to use multiplication to solve an equation. Give examples to support your answer

Answers

Answer: 1,796

Step-by-step explanation:

We are given that : At the chicken ranch this morning there were 7,149 chicks.

i.e. The number of new chicks before today = 7,149

Later  today some more chicks hatched. now the ranch has 8,945 chicks.

i.e. The number of new chicks after today = 8,945

Then, By Subtraction operation

Number of new chicks hatched today = ( Number of new chicks after today) - (Number of new chicks before today )

=  8,945- 7,149 = 1,796

Therefore , the number of new chicks hatched today =  1,796

Experimental value: 16.5 sec
Theoretical value: 17.1 sec

4. Find the percent error in this situation:
Estimated value: 1081
Actual value: 1150

Answers

The formula for percent error is:

((Approximate value -  exact value) / exact value) x 100

1) 14-12 = 2

2/12 = 0.1666

0.166 x 100 = 16.7%  (Rounded to nearest tenth)

2) 231 - 215 = 16

16/215 = 0.74419

0.74419 x 100 = 7.4419% ( Round as needed)

3) 17.1 - 16.5 = 0.6

0.6/16.5 = 0.36364

0.36364 x 100 = 3.6364% (Round off as needed)

The value of t in the given expression is t = 8

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression we need to simplify it for t,

The expression is 1/4t - 6 = -4

So, add 6 to both sides,

1/4 t -6 + 6 = -4 + 6

1/4 t = 2

Multiply by 4 to each side,

1/4 x 4 t = 2 x 4

t = 8

Hence, the value of t in the expression given is 8

So its difficult to show

Y= X-6 so what ever x is, y is six less than that so

X= -4 Y= -10

X= 0 Y=-4

X=4 Y=0

X=8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that

X=-4 Y= -5

X=0 Y= -2

X=4 Y=1

X= 8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= -2

Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.

Y= 2+ 1/4x  so whatever x is y is 1/4 of x add 2

X=-8 Y= 0

X= -4  Y = 1

X=0 Y=2

X=4 Y=3

X=8 Y=4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Do this method for 9

y = 2x -3 so whatever x is, y is  2 times that -3

y=2x +1 so whatever x is y is 2 times that +1

y= 2x so whatever x is y is 2 times that
