Lila thought of a whole number and added the next whole number to it. What was the original number she thought of if the sum was 22?
Answer:
10Step-by-step explanation:
Let the original whole number be x and the next whole number be x+2
If Lila added both number and the sum was 22, then:
x + (x+2) = 22
x+x+2 = 22
2x +2 = 22
2x = 22-2
2x = 20
divide both sides by 2
2x/2 = 20/2
x = 10
Hence the original number she thought of was 10

Write a slope intercept equation for line with the given characteristics m=-3/5 passes through (4,-4)
Step-by-step explanation:
Hey there!
Given;
Slope (m) = -3/5
And passes through the point(4,-4).
Now; The equation of a line in slope intercept form is y= mx+b.
So, try to bring it in y= mx+b form.
Firstly let's use one-point formula.
[tex](y - y1) = m(x - x1)[/tex]
Now, keep all values.
[tex](y + 4) = \frac{ - 3}{5} (x - 4)[/tex]
Now, simplify to get answer.
[tex]5(y + 4) = - 3(x - 4)[/tex]
[tex]5y + 20 = - 3x + 12[/tex]
[tex]5y = - 3x + 12 - 20[/tex]
[tex]5y = - 3x - 8[/tex]
[tex]y = \frac{ - 3}{5} x - \frac{8}{5} [/tex]
Therefore the equation is y = -3/5x - 8/5.
Hope it helps...

If CD = AB and AB = 8, then CD = 8
Answer:
sure
Step-by-step explanation:
Nes and m are intersected by transversal t. ∥ m. Lines l and m are horizontal with l above m and intersected by transveral t. Angles 1, 2, 3, and 4 are formed where t intersects l with 1 and 3 above l from left to right and 2 and 4 below it. Angles 5, 6, 7, and 8 are formed where t intersects m with angles 5 and 7 above line m from left to right and 6 and 8 below it. Select all the angles that are supplementary to ∠4.
Answer:
The supplementary angles to ∠4 are;
∠3, ∠2, ∠7, ∠6, and ∠5
Step-by-step explanation:
The given information are;
The angular orientation of lines l and m = horizontal lines
Therefore l and m are parallel lines
The transversal line to lines l and m = Line t
Therefore, we have;
Angles between line t and line l = 1, 2, 3, and 4
The order of arrangement of the angles between line t and line l are from top left in a clockwise order;
1, 3, 4, and 2
Similarly, the order of arrangement of the the angles between the transversal t and the line m are from top left in a clockwise order;
5, 7, 8, and 6
Therefore, we have;
The supplementary angles to ∠4 are;
∠3, ∠2, ∠7, ∠6, and ∠5
∠3 and ∠4, ∠4, and ∠2, angles on a straight line between lines l and t
∠4 and ∠7 are opposite interior angles (Opposite interior angles are supplementary)
∠7 ≅ ∠6, ∠7 and ∠6 are alternate angles (
∠7 = ∠6 Definition of congruency
∴ ∠4 and ∠6 are supplementary (Transitive property)
∠4 and ∠5 are alternate interior angles (Alternate interior angles are supplementary).

7/11 ÷ 21/55 pls help me
9514 1404 393
Answer:
5/3
Step-by-step explanation:
You can divide fractions a couple of ways:
1. Invert the denominator and multiply
[tex]\dfrac{7}{11}\div\dfrac{21}{55}=\dfrac{7}{11}\times\dfrac{55}{21}=\dfrac{55\cdot7}{11\cdot21}=\boxed{\dfrac{5}{3}}[/tex]
2. Make both fractions have the same denominator and use the ratio of their numerators
[tex]\dfrac{7}{11}\div\dfrac{21}{55}=\dfrac{35}{55}\div\dfrac{21}{55}=\dfrac{35}{21}=\boxed{\dfrac{5}{3}}[/tex]

The simple interest formula is I = Prt, where I represents simple interest on an amount, P, for t years at a rate of r, where r is expressed as a decimal. What is the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years?
Answer:
$80
Step-by-step explanation:
From the question, we are given The simple interest formula as I = Prt,
where l = simple interest on an amount= $40
t= years=5years
at a rate r= 10%
The rate= 10/100= 0.1
Then since we are looking for P, we can make P subject of formula from this expression;
I = Prt
P=I/rt
P= 40/(0.1 ×5)
P= 40/0.5
P= 80
therefore, the amount of money p that is needed is $80
Answer:
the answer would be $80. :)

The mass of a teapot and 4 cups is 1,280 grams. The mass of the same teapot and 10 cups is 2,720 grams. Each cup has the same mass. What is the mass of the teapot?
Answer: 320 grams
Step-by-step explanation:
Let the mas of the teapot be denoted by a
Let the mass of the cups be denoted by c
The question can be turned into an equation which will be:
a + 4c = 1280 ......... equation i
a + 10c = 2720 ........ equation ii
Subtract equation i from ii
6c = 1440
c = 1440/6
c = 240 grams
The mas of the cup is 240 grams
From equation i
a + 4c = 1280
a + 4(240) = 1280
a + 960 = 1280
a = 1280 - 960
a = 320 grams
The mass of the teapot is 320 grams

A telephone number has the form NXX-ABC-XXXX. Today N is 2-9, and X is 0-9. However, there are exceptions as 37X and 96X are reserved for future use. Additionally N9X is reserved for expanding the total numbers at a later date. Finally, N11 is reserved for service numbers. How many total area codes are currently available given this information?
Answer:
The total area codes that are currently available is 692.
Step-by-step explanation:
The area code is of the form: NXX.
The variable N can take values,
N = {2, 3, 4, 5, 7, 8 and 9}
The variable X can take values,
X = {0, 1, 2, 3, 4, 5, 7, 8 and 9}
Considering that repetitions are allowed.
The total possible number of area codes is:
T = 8 × 10 × 10 = 800
So, there are 800 possible area codes.
The exception codes are:
{37X, 96X, N9X and N11}
There are 10 possible combinations for 37X.There are 10 possible combinations for 96X.There are 80 possible combinations for N9X.There are 8 possible combinations for N11.So, the number of reserved area codes is, 10 + 10 + 80 + 8 = 108.
Then the area codes that are currently available is, 800 - 108 = 692
Thus, the total area codes that are currently available is 692.

which function has zeros of -8,1 and 3?
Answer:
A. y = (x - 3)(x + 8)(x - 1)
Step-by-step explanation:
To find zeros of a polynomial, we set the polynomial equal to zero.
We can eliminate C and D; as we set them equal to 0, we see that a root would be 0 due to x. Since we are not looking for a root of 0, those 2 answer choices are incorrect.
Between A and B, A is correct:
A
0 = (x - 3)(x + 8)(x - 1)
x = -8, 1, 3
B
0 = (x + 1)(x - 8)(x + 3)
x = -3, -1, 8
Answer:
Answer A is the correct one.
Step-by-step explanation:
Which function has zeros of -8,1 and 3? We convert each of these zeros into factors, as follows: (x + 8), (x - 1), (x - 3). Answer A is the correct one.
