30°
8 + 6x
4x + 2
in a triangle
Answer:
x=12
Step-by-step explanation:
Simplifying
30 + 4x + 2 = 8 + 6x
Reorder the terms:
30 + 2 + 4x = 8 + 6x
Combine like terms: 30 + 2 = 32
32 + 4x = 8 + 6x
Solving
32 + 4x = 8 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
32 + 4x + -6x = 8 + 6x + -6x
Combine like terms: 4x + -6x = -2x
32 + -2x = 8 + 6x + -6x
Combine like terms: 6x + -6x = 0
32 + -2x = 8 + 0
32 + -2x = 8
Add '-32' to each side of the equation.
32 + -32 + -2x = 8 + -32
Combine like terms: 32 + -32 = 0
0 + -2x = 8 + -32
-2x = 8 + -32
Combine like terms: 8 + -32 = -24
-2x = -24
Divide each side by '-2'.
x = 12
Simplifying
x = 12

A chemist wishes to mix a solution that is 12% acid. She has on hand 6 liters of a 4% acid solution and wishes to add some 16% acid solution to obtain the desired
12% acid solution. How much 16% acid solution should she add?
Complete the table.
Liters of
Solution
Percent Acid Liters of
(as a decimal) Pure Acid
0.04
6
Х
0.16
0.12
Answer:
25 liters of the 16% solution should be added.
Step-by-step explanation:
pure acid amount + pure acid amount = total pure acid amount
0.02*10 + 0.16*x = 0.12*(10+x) <<<---=== it is your balance equation; x is the amount (in liters) of the 16% solution.
0.02*10 + 0.16x = 0.12*10 + 0.12*x
0.16*x - 0.12*x = 0.12*10 - 0.02*10
(0.16 - 0.12)*x = 0.12*10 - 0.02*10
x = %280.12%2A10-0.02%2A10%29%2F%280.16-0.12%29 = 25.
Answer. 25 liters of the 16% solution should be added.
Check. %280.02%2A10+%2B+0.16%2A25%29%2F%2810+%2B+25%29 = 0.12 = 12% of concentration of the final mixture. ! Correct !

Laura says her triangle has angle measures of 100', 88°, and 72°.
Answer:
First, realize that angle ABC is the sum of the two other angles. Hence, form an equation in which you subtract the measure of one of the angles from angle ABC to get the measure of the other angle -- the one you are solving for.

Two boys A and B are a two diametrically opposite points on a circle. at one instant the two start running on the circle
Step-by-step explanation:
let the distance travel by both be a&b
a has a distance of d1 like wise b
speed=distanc/time
d1=2v
d2=4v
total distance
d1+d2=180
2v+4v=180
6v=180
v=30
d1=2*30
d1=60
d2=4*20
d2=120
now start u get u starting
not that there meet at same point so now calculate the time they will trave in there various direction
time=distance/velocity
but they but move at a standard velocity
Answer:
is this the full question: Two boys A and B are at two diametrically opposite points on a circle. At one instant the two start running on the circle; A anticlockwise with constant speed v and B clockwise with constant speed 2v. In 2 minutes, they pass each other for the first time. How much later will they pass each other for the second time?
if yes than this is the answer:-
A speed = v
B speed = 2v
Time to meet = 2 minutes
d= pi r ( distance they have to run to meet)
they are running towards each other.
(2v+v)
speed = 3v
d=rt
pi*r = 3v*2
r= 6v/pi
circumference = 2* pi*r
=2*pi*(6v/pi)
=12v
...
Now distance to travel to meet = 12v
speed = 3v
t=d/r
t= 12v/3v
t= 4 minutes
I hope this helps a little bit.

If PQRS is a kite, find m angle Q
Answer:
m<Q = 78°
Step-by-step explanation:
First, find the value of x:
7x + 2 = 10x - 31 (Non-vertex angles of a kite are congruent to each other)
Collect like terms
7x - 10x = -2 - 31
-3x = -33
Divide both sides by -3
x = 11
Find m<Q:
Sum of all angles in a kite = 360°
Therefore,
m<Q + m<P + m<S + m<R = 360°
m<Q + (7x + 2) + 124 + (10x - 31) = 360
Plug in the value of x
m<Q + (7*11 + 2) + 124 + (10*11 - 31) = 360
m<Q + 79 + 124 + 79 = 360
m<Q + 282 = 360
Subtract 282 from both sides
m<Q + 282 - 282 = 360 - 282
m<Q = 78°
Simplify.
