First, let's write down what we know.
AB = 3x
AC = 5x+21
Since B is the midpoint, AB is half the length of AC. The sum of AB + AB is equal to the length of AC.
AB + AB = AC
Let's plug in our values.
3x + 3x = 5x + 21
Simplify the left side.
6x = 5x + 21
Subtract 5x from both sides.
x = 21
Now, let's plug in 21 for x in AB
AB = 3x = 3(21) = 63
Need help with #12
Please help
Step-by-step explanation:
If the figure is triangle then,
Let PR be x
So,
PQ+QR+PR= 180 (Sum of all the angles of the triangle)
Therefore,
6x+25+16-3x+x=180
4x+36=180
4x= 180/36
x= 144/4
X= 36
NOW,
PQ= 6x+25
= 6(36)+25
= 216+25 = 241= PQ.
QR = 16-3x
= 16-3(36)
= 16-108
= -92
PR = 36
hope it helps

PR = 36

Hanks pickup can travel 45 miles on 3 gallons of gas. How many gallons will Hanks pickup need to travel 30 miles?
We have an algebra problem.
We will find that Hank's pickup needs 2 gallons of gas to travel 30 miles.
The information given is:
The pickup can travel 45 miles on 3 gallons of gas.
To find the number of miles that the pickup can travel per gallon of gas, we need to find the quotient between the amount that he travels (45 miles) and the amount of gas that he uses (3 gallons)
This is:
r = (45 miles)/(3 gallons) = 15 miles/gallon.
Now that we know this, the number of gallons needed to travel 30 miles is given by:
N = (30 miles)/(15 miles/gallon) = 2 gallons.
N = 2 gallons.
The pickup needs 2 gallons to travel 30 miles.

the quotient of five times a number 7 is no more than 10
Answer:
[tex]x \ge3.5[/tex]
Step-by-step explanation:
First, write the given in the form of a mathematical equation rather than words. I'll call the mystery number given in the question [tex]x[/tex]:
[tex]\frac{5*7}{x} \leq 10[/tex]
Simplify:
[tex]\frac{35}{x} \leq 10[/tex]
Solve for x:
[tex]\frac{35}{x} *x\leq 10*x[/tex]
Simplify the fraction:
[tex]35\leq 10x[/tex]
Divide by 10 to isolate x:
[tex]\frac{35}{10} \leq x[/tex]
Flip the equation around to make it easier to read:
[tex]x \ge \frac{35}{10}[/tex]
Simplify the fraction:
[tex]x \ge \frac{7}{2}[/tex] or [tex]x \ge3.5[/tex]

Answer:
(6-5a)/(b-a) = n
Step-by-step explanation:
a(n − 5) + 6 = bn
Distribute
an -5a +6 = bn
Subtract an from each side
an -5a+6 -an = bn-an
6-5a = bn-an
Factor out n
6-5a = n(b-a)
Divide each side by (b-a)
(6-5a)/(b-a) = n
Answer:
[tex]a(n - 5) + 6 = bn \\ an - 5a + 6 = bn \\ an - bn = 5a - 6 \\ n(a - b) = 5a - 6 \\ n = \frac{5a - 6}{a - b} \\ thank \: you[/tex]
