Answer:
x = 31
Step-by-step explanation:
For the sum of the saved amounts to be 286, we must have ...
(5x +4) +(4x +3) = 286
9x = 279 . . . . . . . . . . . . . subtract 7
x = 31 . . . . . . . . . . . . divide by 9
The value of x would be 31.
Answer:
(12x + 19) + (22x - 9) = 180°, x = 5
Step-by-step explanation:
Supplementary angles are 2 angles that adds up to 180°
Another words,
(12x + 19) + (22x - 9) = 180°
Now we solve for x by combining like terms:
34x + 10 = 180°
Subtract 10 on both sides:
34x = 170°
Divide 34 on both sides:
x = 5
Answer:
y = 37/36
Step-by-step explanation:
Line A: 2x+2y=8 ⇒2y=-2x+8 ⇒ y=-x+4
Line B: x+y=3 ⇒y=-x+3
Therefore: y=y then:
-x+4=-x+3
-x+x=3-4
0≠-1 ⇒There is no solution because the lines are parallels
Answer: There is no solution
