Answer:

The correct equation form for finding the price of a sandwich is 5x + 1.25 = 38.75 and the cost of each sandwich was $ 7.50

Step-by-step explanation:

1. Let's check all the information given for solving this question:

Cost of bag of chips = $ 1.25

Cost of sandwich = x

Cost of total order = $ 38.75

2. The formula for find the cost of sandwich (x) is this:

5x + 1.25 = 38.75 (Joaquin ordered 5 sandwiches and a bag of chips)

5x = 37.50 (Subtracting 1.25 at both sides)

5x/5 = 37.50/5 (Dividing by 5 at both sides)

x = 7.50

The cost of each sandwich was $ 7.50

What fraction is equivalent to the whole number 6?

Well, any fraction which result gives you 6 is a fraction that would fulfill the requirement, I'll give you a few examples so you can grasp the idea:

6 = 6/1 = 12/2 = 18/3 = 24/4 = 30/5 = 36/6 = 42/7 = 48/8 = 54/9 = 60/10

Select all the expressions that are equivalent to –8.

NeTakaya

Answer:

The only one I can see right now is (C)

Step-by-step explanation:

Because a positive divided by a negative is negative, so 80/-10 is -8.

For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers? I can help in comments if you tell me.

What is the result of isolating x2 in the equation below?(x + 1)2 + ( -8)2 =9A. x2 = -y2 - 2x +16y - 56B. x2 = y2 +2x+16y +56C.

Anit [1.1K]

The expression we have is:

$(x+1)^2+(y-8)^2=9$

Step 1. Use the binomial square formula:

$(a+b)=a^2+2ab+b^2$

Applying this formula to the first binomial squared:

$x^2+2x+1+(y-8)^2=9$

Step 2. Apply the formula for the square of a binomial to the second binomial:

$x^2+2x+1+y^2+2(y)(-8)+(-8)^2^{}=9$

In this case, we have some operations to solve before we move on to isolating x. So we solve the operations:

$x^2+2x+1+y^2-16y+64^{}=9$

Step 3. Move the terms that are not x squared to the right side of the expression. Remember that when we move one term from one side of the equation to the other, the term must change its sign. We get the following:

$x^2=9-2x-1-y^2+16y-64$

Step 4. Combine like terms and arrange terms in order from the greatest exponent to the lowest and leave the independent term at the end:

$x^2=-y^2-2x+16y-56$

And that is the final result, which is option A.

Answer: Option A.

Find the length of the mid segment (median)

velikii [3]

Answer:

Step-by-step explanation:

Median of a trapezoid = sum of 2 bases divided by 2

Bases = 10 and 16

Median = (10 + 16)/2

10 + 16 = 26

26/2 = 13

Median = 13
