Sandi bought a sandwich and a milkshake. She spent $12 in all. The equation s + 4.25 = 12 can be used to determine the cost of each sandwich. Which of the following os the solution to the equation?
A. $7.75. C. $16
B. $8.75. D. $16.25

Answers

Answer 1
the answer is A $7.75
Answer 2
answer:
A) $7.75

explanation:
To find s, we need to isolate the variable. Use the inverse property of addition to subtract 4.25 from both sides. s + 4.25 - 4.25 = s. 12 - 4.25 = 7.75. Now we're left with s = 7.75.

A pair of equations is shown below:

y = 7x − 8
y = 5x − 2

Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution.

Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer

Answers

Answer:

Part A) If would probably be smart to use substitution because y is already solved for, so we can substitute the value of y as a function of x into the other equation.

y=7x-8

y=5x-2

7x-8=5x-2

   +8     +8

-----------------

7x=5x+6

-5x  -5x

----------------

2x=6

/2   /2

-----------

x=3

y=7x-8

y=21-8

y=13

Part B) The lines will intersect at point (3, 13)

Step-by-step explanation:

hope this helps

so sorry if this is wrong

did this for hw

Answer:

Step-by-step explanation:

part a:

substitution

7x - 8 = 5x - 2

2x - 8 = -2

2x = 6

x = 3

y = 7(3) - 8 = 21 - 8 = 13

y = 13

Answers

Answer:

? would equal 25

Step-by-step explanation:

You plug the input into the rule. When x=4, y=21 because 4(4) +5 =21. The 4 in the parentheses is the input. So you would do the same when the input is 5. 4(5) +5= 25

Hope this helps! Please let me know if you need anymore clarification :)

So for the in it’s 4x+5 so input your 4 for the x so 4•4+5 that equals 16+5 which equals 21 then you go and put 5 as the input so 4•5+5 would be 20+5 which is 25

Answers

1) 1/4 times 4 equals 1
so 4 times 5 equals 20 miles

2) 1 times 4 equals 4
so 4 times 2 equals 8 cm

3) 1/4 times 4 equals 1
so 4 times 6 equals 24
and 24 times 2ft equals 48 ft

Answer:

1) 20 miles

2) 8cm

3)

Step-by-step explanation:

1) Each mile is 1/4 of an inch. and there are 5 inches.

    To figure out how many miles we do we need to figure out how many 1/4 of an inch is in 5 inches.

    First, we figure out that 4 of 1/4 of an inch = 4 miles because you have 4 parts = 4/4 which = 1.

    So we figured out that 1 inch = a mile.

    Then the rest is really easy. We add 4 together 5 times

    4 plus 4 plus 4 plus 4 plus 4 which = 20

    (Another way you could do it is to multiply 4 by 5)

     So the answer to #1 is 20 miles to walk to school.

   

2) 2cm (Centimeter) = 1 m (meter) and there are 4 meters in the car

    Basically, it is straightforward based on what I did on the first problem

    So you add 2 + 2 + 2 + 2 to get 8m

    Or you multiply 2 by 4 to get 8m

    So if the car is 4m the length is 8cm

3) sorry to busy to do number 3, i hope you figure it out.
