Answer:
3.85
Step-by-step explanation
7.7 divided by 2 = 3.85
So if you double 3.85 you get 7.7 and then add 20 to 7.7 then you get 27.7
Let the number they are thinking of be X.
They double x , which would be 2x.
They then add 20, which would be 2x +20
So you have 2x + 20 = 27.7
Now we can solve for x:
Subtract 20 from both sides:
2x = 7.7
Divide both sides by 2:
x = 7.7 / 2
x = 3.85
The original number was 3.85

Kayla thinks that the slope of a vertical line is undefined, while Joshua argues that the slope of a vertical line is zero. Who is correct? *
Answer:
Kayla is correct
Step-by-step explanation:
For a vertical line, the x-value is the same
This means there is no change in the x value
A slope is calculated by dividing by the change in x value
since in this case , we will be dividing by zero, it means that the value of our slope is going to be undefined
This means that Kayla is correct

Interest = $45
Principal = ?
Interest rate = 3%
Time = 2 years
What interest is this. Simple or compound? Cause both have different formulas.
Simple interest
A(interest) = (Principal× Rate×time)
A= (P ×3×2years)/100%
$45 = 6/100P
4500= 6p
4500/6 = P
principal= $750.

the two angles measuring (30 + 2 a)degree and (125 -a) degree supplementary to each other, then find the value of a.
Answer:
The value of a is 25
Step-by-step explanation:
When two angles are supplementary, they add up to 180 degrees
Mathematically,
(30 + 2a) + (125-a) = 180
30 + 2a + 125 - a = 180
a + 155 = 180
a = 180-155
a = 25 degrees

Which expression is equivalent to 2d^2-6/d^2+2d-48 / d-3/2d+16if no denominator equals zero?
Please help. On Pluto
Answer:
B; 4/d-6
Step-by-step explanation:
We want to perform a division here
Flipping the right hand side while changing the sign to multiplication, we have that;
(2d - 6)/ (d^2 + 2d -48) * (2d + 16)/d-3
= 2(d-3)/(d^2 + 2d - 48) * 2d + 16/d-3
= 2/(d^2 + 2d - 48) * 2d + 16/1
2/(d-6)(d + 8) * 2(d + 8)/1
= 2/d-6 * 2/1
= 4/d-6

Answer:
RS = XY (since the two a triangles are similar, you have to match the sides up and then set the values equal to eachother to find the value of x)
3x +2 = 5x -3 (subtract 5x from both sides)
-2x +2 = -3 (subtract 2 from both sides)
-2x = -5 (divide both sides by -2 to isolate x)
x = 2.5 (take the value of x and plug it into the expression given for RS)
3(2.5) +2 (multiply)
7.5 +2 (add)
9.5 (this is the length of RS)

consider the equation _. determine the steepness in the line between x=1 and x=2.
Answer:
2/3
Step-by-step explanation:
Firstly we get the y value at both x points
At x = 1
y = 2/3 + 1/2 = (4 + 3)/6 = 7/6
At x = 2
y = 4/3 + 1/2 = (8 + 3)/6 = 11/6
The slope formula is
m = (change in y)/change in x
The slope is thus;
(11/6-7/6)/(2-1) = 4/6 = 2/3

A salesgirl is paid a basic wage of $140 per
week. In addition, she is paid a commission of
5% on the value of goods she sells. How much
commission will she be paid on sales amount-
ing to $1 525 and what is her gross wage for the
week?
Answer:
This week her gross wage is equal to $216.25
Step-by-step explanation:
From the question it self we can make the following equation.
Let "W" be the gross wage for the week.
Let "V" be the value of the goods she sells.
then.....
W = $140 + 0.05V
(Where $140 is the price she will be paid for just working and 0.05V is the commission she will get paid this week)
Now that we know what "v" equal to, we can easily find out her Gross Wage this week by inserting in the value of V. And so we get.......
W = $140 + 0.05V
W = $140 + 0.05 x 1525
W = $140 + 76.25
W = $216.25

Which function is not linear? A. f(x)=x/4 B. f(x)=2x+1 C. f(x)=-3 D. f(x)=-1/x
Answer:
f(x) = -1/x
Step-by-step explanation:
Here, we want to find the function that is not linear
A linear function is of the form;
y = mx + b
where m can be zero, or b can be zero
The only option that does not follow this description is
f(x) = -1/x
Arlene has raised $56 for her class field trip. This is $14
more than three times the amount Adam has raised.
Which equation could you use to find how much money
Adam has raised?
Assuming Adams amount is x, three times his amount will be 3x. $14 more than the times Adam's amount will be 14 +3x.
Therefore if Arlene's money is $56 which is $14 more than three times Adam's amount, then the equation will be ;
14+3x=56
