Answers

Answer:

x + y + z = 49

2.50x + 7y + 1.50z = 147

y + 7 = z

Step-by-step explanation:

Before you even start setting up the equations, create variables for information needed, but not given in the problem:

Variable x = number of tacos

Variable y = number of burritos

Variable z = number of sodas

The first piece of information we are given is the number of items so make this into an equation:

x + y + z = 49

Next we are told how much everything cost in total so make this into an equation:

2.50x + 7y + 1.50z = 147

Lastly, we are informed Rosa bought 7 more sodas than burritos so form an equation using this information:

y + 7 = z

find the domain of f(x) = x+5/ 2-x

about a point in the middle of the figures to create Figure B.

Answers

Answer:

B

Step-by-step explanation:

Process of elimination, it wasn't reflected because point a and point E are on opposite sides in figure B compared to figure A. It wasn't rotated 90° Because point H is once again on the complete opposite side, if it was 90° it would be to the left or the right, not opposite. It wasn't translated Because all points are in different places.

Of the 121,301,000 men in the U.S., 3.38% didn’t complete 9th grade. How many men is this?

Answers

Answer:

4099973

Step-by-step explanation:

I hope this is correct! :)

Sorry if I'm wrong...

Approximately 4,100,938 men in the U.S. didn't complete 9th grade. To find out how many men in the U.S. didn't complete 9th grade, we can use the percentage given and calculate it as follows: Number of men who didn't complete 9th grade = (Percentage of men who didn't complete 9th grade / 100) * Total number of men in the U.S.

Given:

Percentage of men who didn't complete 9th grade = 3.38%

Total number of men in the U.S. = 121,301,000

Let's calculate:

Number of men who didn't complete 9th grade = (3.38 / 100) * 121,301,000

Number of men who didn't complete 9th grade ≈ 4,100,938

So, approximately 4,100,938 men in the U.S. didn't complete 9th grade.

If two rectangles have the same perimeter, do they have to be congruent?
Explain your thinking,

Answers

9514 1404 393

Answer:

  no

Step-by-step explanation:

For the perimeter to be the same, the sum of side lengths must be the same. That does not mean the side lengths themselves must be the same.

A 4×4 rectangle (square) and a 5×3 rectangle have the same perimeter, but are not congruent.

9. The graph of which the following equations has x-intercepts of 4 and -4?
(1 Point)
O y + 4 = x
O y - 4 = x
O y + 16 = x2
O x + 16 = y2

Answers

Remember that an x-intercept has a y-value of 0, so the question here really “Which of the following equations has (0,4) AND (0,-4) as solutions.”

The first two each work with one of the points, but not the other, so they’re not the answer.

The last one doesn’t work for either point.

The third one, y+16=x^2, works for both.

0 + 16 = (4)^2 is true.

0 + 16 = (-4)^2 is true.
