Answer:
4 and 40
Step-by-step explanation:
2/5 of 10 is 4
2/5 of 100 is 40
Answer:
10
Step-by-step explanation:
If we plug in any negative number as x, the result will always be greater than 4, which rules out answers A and B
lets try plugging in 4 as x to test answer C:
2(8-4)
2(4)= 8
8 is greater than 4, therefore C is wrong.
Lets try 10 as X (answer D):
2(8-10)
2(-2)
-4
We know that -4 is less than 4, therefore it makes the inequality true! :)
Answer:
<em>h = 6.2</em>
Step-by-step explanation:
You need to find h.
The dashed triangle is a right triangle. 8 is the hypotenuse. h is a leg. The other leg is the half of the side of the base, 5.
the value of m is 24°
Step-by-step explanation:
m+7+2m+11=90° ( being complementary angle)
3m+18°= 90°
3m =90- 18°
3m = 72
m= 72/3
m=24°
Answer:
Given first price: $10
New price: $12
Difference: New price - Old price
⇒ $12 - $10
⇒ $2
Now difference precentage:
(Difference÷Initial price)×100
⇒ (2 ÷ 10) × 100
⇒ 0.2 × 100
⇒ 20%
Thus the increase is by 20%
