The sum of two consecutive even integers is 42. What is the product of the two consecutive even integers?
Answer:
440
Step-by-step explanation:
The average of the integers is the odd integer between them. That is found by dividing their sum by 2:
42/2 = 21
The even integers are 20 and 22. Their product is 20∙22 = 440.

Tell me the slope of line please
Answer:
Slope is -6/7
Step-by-step explanation:
(See attachment below)
The slope of the line in simplest form is -7/20.
What is slope?The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
Using the Slope Equation
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
Given that a line representing the "rise" and a line representing the "run" of the line.
Here,
y1 = 7 x1 = -10
y2 = 0 x2 = 10
Slope of line = (y2 - y1) ÷ (x2 - x1)
= (0 - 7) ÷ [10 - (-10)]
= -7 ÷ 20
= -7/20
Hence, The slope of the line in simplest form is -7/20.

4. Which percent is equivalent to the fraction 37/50?
A gopher has dug holes in opposite corners of a rectangular yard. One length of the yard is
21 feet and the distance between the gopher's holes is 29 feet. How wide is the yard?
Answer:
20 yards
Step-by-step explanation:
21 + x = perimeter (x being the width because it is unknown)
so far this would look like an incomplete triangle, or in other words, it is connected to Pythagoras theorem.
a^2 +b^2 = c^2 but since we don't know one of the sides of the triangle, (a^2 in this case) we can reverse the equation to get our answer.
=
c^2 - b^2 = a^2
c would represent the 2 holes the gophers dig on opposite sides of the rectangular yard, and since we already know the length, we can use this equation.
c = 29
b = 21
a = x (unknown)
=
29^2 - 21^2 = x^2
now we can just square c (29) and b (21)
29^2 = 841
21^2 = 441
so now the equation looks like
841 - 441 = x^2
now just some simple subtraction
841 - 441 = 400
so...
400 = x^2
and then to get x without the ^2 we can just get the square root of 400, which counters the ^2.
=
√400 = 20
so there you have it!
20 = x
or
20 = a
or
20 = the width!

gianna has completed 30 sit ups whitch is 20% of her goal how many does she plan to do
Explanation:
We know that Gianna has completed 30 sit-ups, which is 20% of her goal. To find her goal, we will need to change the 20% to a 100%. The 100% means that she has achieved her goal. To do this, we can write an equation. However, since 20 is divisible by 100, we will solve this problem with a shorter way.
Solution:
30 sit-ups = 20% goal finished=> 30 x 5 sit-ups = 20 x 5% goal finished=> 150 sit-ups = 100% goal finishedFinal Answer:
This means that Gianna's goal is to reach 150 sit-ups.
Answer:
150 situps
Step-by-step explanation:
I think the best way to solve these types of problems in conceptually. If Gianna has only done 20% of her goal, we can ask ourselves by what number can we multiply 20% by to get 100%. In this case it is 5.
This equation looks like 5 x 20% = 100%
So, now that we know a factor of 5 will get us to Gianna's total goal, we just need to multiply the 30 situps she has already done by 5 and we will get 150 situps.
This could also be solved by setting up a conversion. which would look like:
30 situps/ 20% = ? number of situps/ 100%
Now solve for the ? number of situps. You can treat the percentages as regular whole numbers.
Either way will give you the answer of 150 situps.
hope this helps! :)

Answer:
-90
Step-by-step explanation:
You would need to input each x value from the table into your equation in order to find the output (y value)
f(9) = -9(9) - 9 = -90
f(0) = -9(0) - 9 = -9
f(7) = -9(7) - 9 = -72
f(4) = -9(4) - 9 = -45
f(-9) = -9(-9) - 9 = 72
After plugging in all of these numbers, of the answer choices given, -90 would be correctly found in the table.
Answer:
(d) -90
Step-by-step explanation:
The function can be simplified to ...
f(x) = -9(x +1)
This means any integer x will produce a y-value that is a multiple of 9. Among the answer choices, those are 90 and -90. We can try these to see if either of the x-values are in the table.
90 = -9(x +1)
-10 = x +1
-11 = x . . . . . not in the table
__
-90 = -9(x +1)
10 = x +1
9 = x . . . . . . . the first row of the table
The value -90 would be correctly found in the table.

Answer:
The answer is D.
Step-by-step explanation:
For this question, you have to recall the properties of a triangle. Ergo, remember what a triangle is. Here are some of them.
1. A triangles has 3 sides, angles, and vertices.
2. All angles of a triangle add up to 180 degrees.
3. The sum of the length of any two sides of a triangle is greater than the length of the third side.
This third property of a triangle will help us solve the problem. Just do trial and error for these four answer choices and see which one fails this property. The only answer choice that fails is D because 3 + 5 = 8, and 8 < 9 (8 cannot be > 9).

The value of a and b for the given systems of linear equations will be 7.5 and -7.5.
What is the equation?A mathematical equation asserts the equality of two expressions, which may or may not contain variables or integers. Equations are fundamental concerns and attempts to methodically resolve these concerns have served as the primary driving forces behind the creation of mathematics.
It is given that, the given linear equations are,

3a+(a-15)=15
3a+a-15=15
4a=15+15

a=30/4
a=7.5
Put the value of a in equation 2 to obtain b as
b=a-15
b=7.5-15

1. A man is 24 years older than his son. In two years, his age will be twice the age son. What is the present age of his son?
Answer:
I think his son is 12
Step-by-step explanation:
12 x 2 = 24
Step-by-step explanation:
x + 24
x + 2
x + 24 + 2 = x + 26
(x + 26)/(x + 2) = 2/1
x + 26 = 2x + 4
x = 22 years
The present age of the son is 22 years.
Let the age of the son after 2 years be x.
Then the age of the man after 2 years be 2x.
The present age of son = x - 2
The present age of man = 2x - 2
According to the question:
2x - 2 - (x - 2) = 24
