Answer:
10, because only 5 and 5 are positive which means a increase or gained
Answer:
1/2
Step-by-step explanation:
1/5 equals 2/10, so:
? - 3/10 = 2/10
To go backwards, we must add 3/10 to 2/10 and it is equal to 5/10, or 1/2.
So, 1/2 or 5/10 - 3/10 = 2/10
The third equation is true
3.95m+8.95b=47.65
good luck
The answer is freakin 6 my people
Answer:
8. The length of the longest side is 40 ⇒ H
Step-by-step explanation:
8. In the given figure
∵ The triangle has two equal sides 2x + 12 and 5x - 9
→ Equate their expressions to find the value of x
∴ 5x - 9 = 2x + 12
→ Add 9 to both sides
∵ 5x - 9 + 9 = 2x + 12 + 9
∴ 5x = 2x + 21
→ Subtract 2x from both sides
∵ 5x - 2x = 2x - 2x + 21
∴ 3x = 21
→ Divide both sides by 3 to find x
∵ =
∴ x = 7
∵ The longest side is 6x - 2
→ Substitute the value of x in its expression to find its length
∴ The longest side = 6(7) - 2 = 42 - 2
∴ The longest side = 40
∴ The length of the longest side is 40
