1. 118
2. 62
4. 118
5. 118
6. 62
7. 62
8. 118
(8x+12)+(3y-9)= 8x+3y+3=78
subtract 3 from both sides
8x+3y=78
subtract 8x from both sides
3y=-8x+78
divide both sides by 3
y=-8/3x+26 or y=-2.666666666x+26
substitute for y
8x+3(-8/3)+26=78
subtract the 26 from both sides
8x+3(-8/3)=52
distribute the 3
8x- 7.99999999998=52
add the -7.999999999998 to bother sides
8x=60
divide both sides by 8
x=7.5
substitute for x
8(7.5)+3y=78
60+3y=78
subtract 60 from both sides
3y=18
divide both sides by 3
y=6
so x=7.5 and y=6
Answer:
Option (3)
Step-by-step explanation:
There are two parallel lines 'p' and 'q' and a transversal line is intersecting these lines at two distinct points.
Each pair of angles formed on the inner side of the parallel lines but opposite sides of the transversal line are the alternate interior angles.
Pair of angles (∠2 and ∠6) and (∠3 and ∠7) are the alternate interior angles.
Since, alternate interior angles are equal in measure,
∠2 ≅ ∠6
∠3 ≅ ∠7
Option (3) will be the answer.
Question 14:
We are given that:
C = πd
To solve for d, we need to isolate the d on one side of the equation. This means that we need to get rid of the π next to the d.
In order to do so, we can simply divide both sides of the equation by π as follows:
C/π = πd/π
d = C/π .........> The first option
Question (15):
We are given that:
d = rt
To solve for r, we need to isolate the r on one side of the equation. This means that we need to get rid of the t next to the r.
In order to do so, we can simply divide both sides of the equation by t as follows:
d/t = rt/t
r = d/t.........> The third option
Hope this helps :)
