Answer:
x=2
Step-by-step explanation:
7x+9=9x+5 [Corresponding angles]
9-5=9x-7x
4/2=x
x=2
Answer:
<h3>No solutions: 5 - 4 + 7x + 1 = 7x + 1</h3><h3>One solution: 5 - 4 + 7x + 1 = 2x + 1</h3><h3>Infinitely many solutions: 5 - 4 + 7x + 1 = 7x + 2</h3>
Step-by-step explanation:
left side: 5 - 4 + 7x + 1 = 1 + 7x + 1 = 7x + 2
<u>No solution</u> is when we have the same number of x-es and different sums of other numbers on both sides of equation. So we have to put 7 next to x and any numer except 2 at the second place.
So the right side could be 7x+1 or 7x+3 or 7x+125 and so on.
<u>One solution</u> is when we have different number of x-es on both sides of equation. The sums of other numbers could be any numbers.
So the right side could be ex.: 2x+1, x+2, 8x, 3x+(-18), and so on.
<u>Infinitely many solutions</u> is when we have the same number of x-es and the same sums of other numbers on both sides of equation. So we have to put 7 next to x and numer 2 at the second place.
So the right side has to be 7x + 2
The unknown measurements of the triangle are C = 28°, c = 3.76 and b = 7.06.
<h3>Sine rule</h3>
Sine rule is used to show the relationship between sides of a triangle and the angles. It is given by:
Where a, b, c are the sides and the angles opposite the sides are A, B, C respectively.
- A + B + C = 180° (angles in a triangle)
- 62 + 90 + C = 180
- C = 28°
The unknown measurements of the triangle are C = 28°, c = 3.76 and b = 7.06.

Answer:
35, I think is the correct answer.
Step-by-step explanation:
2+8-z=24
10-z=25
z=25+10
z= 35
By saying jane is 1/3 of harvey then J=1/3 H
by removing J and adding the new quantity we git u will got the answer
