Answer:
x = 10
Step-by-step explanation:
The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles. The two non-adjacent interior angles opposite the exterior angle are sometimes referred to as remote interior angles.
In the given problem, the exterior angle is < JUV, and its corresponding remote interior angles are < V and < W.
Establish the following equation according to the exterior angle theorem:
< V + < W = < JUV
88° + (5x + 1)° = (14x - 1)°
Solve for x algebraically:
88° + 5x + 1 = 14x - 1
89 + 5x = 14x - 1
89 + 1 + 5x = 14x - 1 + 1
90 + 5x = 14x
90 + 5x - 5x = 14x - 5x
90 = 9x
90/9 = 9x/9
10 = x
Therefore, the value of x = 10.
Yes because 11 is x and y together and the others are 11xy too
Answer:30+12=42
Step-by-step explanation:
P/M=6/7(2) P/M=12/14
P/M+16=2/5(6) P/M=12/30
Başlangıçtaki M+16=30 M=30
P=12
P+M=42
Use equation C1M1+C2M2=CM
C1=15%, M1=10000 mg (starting ointment)
C2=0% M2=to be found (diluent)
C=12% M=M1+M2 (product)
Solve for M2
0.15*10000+0*M2 = 0.12(10000+M2)
M2=(0.15-0.12)*10000/0.12=2500 mg
Answer: 2500 mg of diluent is required.
<span>the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a</span>
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions
