Erin fought a dragon with 9 heads. then she fought another dragon with 2 fewer heads than the first dragon.How Many Heads Did The Second Dragon Have?

Answers

Answer 1

Answer: 7 fewer heads, since 9-2 would equal 7

Answer 2

Answer:

Final answer:

In this math problem, we're performing a simple subtraction. The first dragon had 9 heads, and the second dragon had 2 fewer, which totals to 7 heads for the second dragon.

Explanation:

The subject of this problem is simple subtraction. If Erin fought a dragon with 9 heads, and then she fought another dragon that had 2 fewer heads than the first, we have to subtract 2 from 9. The calculation would be: 9 - 2 = 7. Hence, the second dragon Erin fought had 7 heads.

Complete the ordered pair so that it is a solution of 2/3 x + y - 1 = 0.(-6, ___)

equation, variables, ordered pair, solution

For this case we have an equation with two variables, "x" and "y". Also, we have that the value of "x" is given by: $x = -6$ . We must find the ordered pair of the solution of the equation.

Let: $\frac {2} {3} x + y -1 = 0$

We substitute $x = -6$ in the equation:

$\frac {2} {3} (- 6) + y -1 = 0\n-4 + y-1 = 0\ny = 1 + 4\ny = 5$

Thus, the ordered pair that is the solution of the equation $\frac {2} {3} x + y -1 = 0$ is $(x, y) = (- 6,5)$

Answer:

$(x, y) = (- 6,5)$

2×-2 +y-1=0
-4+y-1=0
y-5=0
y=5

Which ordered pair could represent the x-intercept?a
0, 4
b
4, 4
c
4, 0
d
None of these

Answers

The ordered pair could represent the x-intercept (4, 0). Thus, option (C) is correct.

The x-intercept is the point where a graph intersects the x-axis.

At this point, the y-coordinate is zero (0).

Therefore, the ordered pair representing the x-intercept will have a y-coordinate of 0.

Also, the standard form to write the x intercept is (x, 0).

a) 0, 4

Not represent the x-intercept.

b) 4, 4

Not represent the x-intercept

c) 4, 0

Represent the x-intercept, because the y-coordinate is 0, which is what we expect for an x-intercept.

d) None of these

Thus, option (C) is correct.

Answer:

Which ordered pair could represent the x-intercept?

a. (0, 4)

b. (4, 4)

c. (4, 0)✓

d. None of these

Step-by-step explanation:

Ordered pair which represent the x-intercept i.e., value of x axis is 'a' and y axis is 0 is c. (4,0).

Hence, (4,0) is the right answer.

A student has earned the following scores on four 100-point tests this marking period: 63, 72, 88, and 91. What score must the student earn on the ﬁfth and ﬁnal 100-point test of the marking period to earn an averagetest grade of 80 for the ﬁve tests?

Answers

In order to have average 80 score from 5 tests, student needs to have 400 points (80%*500=0.8*500=400)
So far he has 63+72+88+91= 314
400-314=86

He needs to get 86 points from the last test.
Since he is obviously getting better at tests, i think he'll manage :)

The time to digest the food in the small intestine is about:A : Six hours

B : Thirty Minutes

C : Three hours

D : Ten hours

Answers

After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. So I would probably say six hours.

Answer: A

Hope this helps! Have an amazing day! :)
