This is my question pls help
Cerrena [4.2K]

Answer:

a = 15

Step-by-step explanation:

Substitute b = 12 , a = 9 into the equation

12 = \sqrt{a^2-9^2}

12 = \sqrt{a^2-81} ← square both sides

144 = a² - 81 ( add 81 to both sides )

225 = a² ( take square root of both sides )

± \sqrt{225} = a , then

a = ± 15

a > 0 , so a = 15

ss7ja [257]

Answer:

a. Strawberry > Rasberry

6.18 > 6.1

b. required more in strawberry

Step-by-step explanation:

Given that

Strawberry = 6.18 pound

Raspberry = 6.1 pound

Based on the above information

As we can see that the number of pounds in strawberry is more than the number of pounds in Rasberry

So, it would be

a. Strawberry > Rasberry

6.18 > 6.1

b.  Here the inequality means that the number of pounds is required more in Strawberry as compared to the Rasberry so that the jam could be made

Arlene had some blackberries. She gave 216 to her teachers. Then she dropped 12. Later, she ate 18. Finally, she gave half of wh
Bingel [31]

Answer:the number of BlackBerry that Arlene had initially was 276

Step-by-step explanation:

Let x represent the number of BlackBerry that Arlene had initially.

She gave 216 to her teachers. This means that she is left with x - 216

Then she dropped 12. This means that she would be left with x - 216 - 12 = x - 228

Later, she ate 18. This means that she would be left with x - 228 - 18 = x - 246

Finally, she gave half of what she had to her friend. This means that the amount that she gave to her friend is (x - 246)/2 and the amount that she has left would be

(x - 246)/2

Now, she has 15. This means that

(x - 246)/2 = 15

x - 246 = 2 × 15 = 30

x = 30 + 246 = 276
