Solve for x.
5x – 4 > 12
AND 12x + 5-4
Step-by-step explanation:
5x - 4 > 12 adding 4 to both sides;
5x - 4 + 4 > 12 + 4
5x > 16 dividing both sides by 5;
x > 16/5
12x + 5-4
12x + 1

Write an equivalent expression so that each factor has a single power. Let m, n, and p be numbers.
Answer:
a^m-n
Step-by-step explanation:
If we have the expression m^a / m^n, we can use exponent rules to simplify this.
Exponent rules say that x^a / x^b = x^a-b. In this case, x is a, a is m and b is n, so the same rule applied here.
So a^m / a^m will be equal to a^m-n

How many ways are there to make change for $3? (Utilize all forms of US currency, such as Silver dollars, half dollars, quarters, nickels, & pennies.) Is there a specific formula to calculate this?
Answer:
300 pennies. 12 quarters. 6 half dollars. 3 silver dollars. 60 nickles. 30 dimes.
Step-by-step explanation:
Pennies have a value of .01 so we add that to equal 300. For three dollars we need 12 quarters. 300 divided by the value of the quarter which is .25 cents. We have six half dollars (we divide 300 by the value of the half dollar). We would need 3 silver dollars since each is worth a dollar each. We would need 30 dimes (300 divided by 10). Finally, we would need 60 nickels (300/5 = 60).
I hope this helps. Feel free to ask any questions.

Trapezoid W'X'Y'Z' is the image of trapezoid WXYZ
under a dilation through point C.
What scale factor was used in the dilation?
1.) -6/5
2.) -5/6
3.) 5/6
4.) 6/5
W'X' is the dilated image, which is smaller than the original, so the scale factor would be less than 1.
Set up a ratio of the dilated figure to the original:
15/18 divide this by 3 to get 5/6
The answer is 3) 5/6

k-4 /9 =3
8+b /-4 = -5
Answer:
k = 31/9 b = 12Step-by-step explanation:
k - 4 = 3
9
k/9 = 3(9) + 4
k = 31/9
----------------------------
8 + b = -5
-4
8 + b = -5 (-4)
8 + b = 20
b = 20 - 8
b = 12
k = 31/9
b = 12
proofing my answer is correct
k - 4 = 3
9
k/9 = 3(9) + 4
k = 31/9
----------------------------
8 + b = -5
-4
8 + b = -5 (-4)
8 + b = 20
b = 20 - 8
b = 12

Question?
anyone mind helping? i want to sleep Given: BA is congruent to BC prove angle 1 is congruent to angle 3.
Answer:
Given that BA = BC which shows that ΔABC is isosceles
And, ∠1 Represents BC
and, ∠2 Represents BA
And as BC and BA are equal, we come to know that ∠1 and ∠2 are equal
∠2 = ∠3 because they are opposite angles.
Therefore we can conclude that ∠1 and ∠3 are congruent because ∠1 =∠2 which ∠2 = ∠3 So, ∠1 = ∠3
If my answer helped, please mark me as the brainliest!!
Thank You!
Answer:
see below
Step-by-step explanation:
since ∠1 ≅ ∠2
opposite angles are equal
therefore, ∠2 ≅ ∠3
P -5, 1 R 4,4..find the slope
Answer:
The slope between (-5,1) and (4,4) is 1/3
Step-by-step explanation:
When you're given 2 points and you must find the slope between those 2 points, you can find the distance between the y values and the x values.
For example in this case, the distance in our first y value is 3. So we know that y is always above x so we have 3/x so far.
Next to find the x values you do the exact same, and we get a distance of 9 from -5 to +4.
Now we have 3/9 which should be simplified to 1/3. When plotting this point, you'll use the strategy Rise over Run or Rise/Run.
(Side Note: Y is always above X so we know the Rise must be Y and the X must be Run.)
Y/X = Rise/Run

Answer:
1. 21+5f = 61
2. 18+5n=50.50
3. 40+30s=220
Step-by-step explanation:
1. SUM of 21 and 5 TIMES a number f is 61
From that sentence, sum means addition and times is multiplication, so:
21+5f = 61
2. Let's identify the given:
Monthly fee: 18
Cost of each call: 5
Variable that symbolizes the call: n
Total cost this month: 50.50
Thus, 18+5n=50.50
3. Identify the given:
Charge of tutor: 40
Charge of tutor every student: 30
Variable representing the number of students: s
Total charge: 220
Thus, 40+30s=220

A company estimates that 0.7% of their products will fail after the original warranty period but within 2 years of the purchase, with a replacement cost of $350. If they offer a 2 year extended warranty for $48, what is the company's expected value of each warranty sold?
Answer:
$44.90
Step-by-step explanation:
The resulting value for the company of replacing a failed product is given by the price of the warranty minus the cost of replacement:
F = $47-$300=-$253
This event has a 0.7% chance of happening.
The resulting value for selling extended warranty to a product that does not fail is given by the price of the warranty:
W = $47
This event has a 99.3% chance of happening.
The expected value is:
EV = $44 * 0.993 + ($47-$300) *0.007
EV = $44.90
The expected value for each warranty sold is $44.90.
I needdd helpppppp what is m<2+m<3?
In triangle ABC:
∠1 = 90°
According to the angle sum property:
∠1 + ∠2 + ∠3 = 180
Since angle 1 is 90 degrees
∠2 + ∠3 = 180 - 90
∠2 + ∠3 = 90° [∠1 + ∠2 + ∠3 = 180]

What is the equation in slope-intercept form of the line that passes through the points ( -4, 47) and ( 2 , -16)?
Answer:
[tex]-\frac{21}{2} x+5[/tex]
Step-by-step explanation:
To find the slope of the equation, you use [tex]\frac{rise}{run}[/tex] , or [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] :
[tex]\frac{-16-47}{2+4}[/tex]=[tex]\frac{-63}{6}[/tex]=[tex]\frac{-21}{2}[/tex]
Then you have to find the y intercept. First, plug in the x of a point and solve:
[tex]\frac{-21}{2}[/tex] * 2= -21
Then, find the distance between the answer and the y of the given point. Since our answer is smaller than the y of the point, we'll get a positive y- intercept.
21-16=5
This will give us the equation:
[tex]-\frac{21}{2} x+5[/tex]
