<span>16=4²
25=5²
</span>So that means the square root of 22 is between 4 and 5.
Square 4.5
4.5² = 20.25
<span>4.5 < √22 < 5
So the nearest whole number would be 5.

a) The solution is x = -9.
b) The solution is x = 15.
<u>Step-by-step explanation:</u>
a) The given equation is 3(x+1)=2(x-3).
To solve this equation, distributive property is used.
<u>The Distributive property :</u>
It is done by multiplying the number outside the bracket with each terms present inside the bracket.
Now, the first step is to multiply 3 with each terms in (x+1) and multiply 2 with each terms in (x-3).
⇒ 3x+3 = 2x-6
Bring x terms on one side and constants on other side,
⇒ 3x-2x = -6-3
⇒ x = -9
b) The given equation is 2(5x-6)=3(3x+1).
To solve this equation,distributive property is used.
Now the first step is to multiply 2 with each terms of (5x-6) and 3 with each terms of (3x+1).
⇒ 10x-12 = 9x+3
Bring x terms on one side and constants on other side,
⇒ 10x-9x = 3+12
⇒ x = 15
Answer:
$7.7
Step-by-step explanation:
Hello, I can help you with this
you can solve this by using a simple rule of three.
Step 1
define
if the wholesale price for a shirt is $5.50,it is 100 percent
$5.50⇔100%
the new price(x) is 40% more than the original, it means 140%
x ⇔ 140%
the relation is
![\frac{5.5}{100}= \frac{x}{140}\\](https://tex.z-dn.net/?f=%5Cfrac%7B5.5%7D%7B100%7D%3D%20%5Cfrac%7Bx%7D%7B140%7D%5C%5C)
Step 2
solve for x(isolate x)
![\frac{5.5}{100}= \frac{x}{140}\\x=\frac{5.5*140}{100}\\x=7.7](https://tex.z-dn.net/?f=%5Cfrac%7B5.5%7D%7B100%7D%3D%20%5Cfrac%7Bx%7D%7B140%7D%5C%5Cx%3D%5Cfrac%7B5.5%2A140%7D%7B100%7D%5C%5Cx%3D7.7)
the price of the shirt in the department store is $7.7
Have a nice day.
Answer:
Theres no picture?
Step-by-step explanation:
The solutions are
1. If A=B implies c = then A ∪ B = B
<span>2. If B is inside A </span><span>e = then A ∩ B = B
</span>3. A ∪ Ø implies d = A
4. A ∩ Ø imiplies <span>a = Ø
</span>5. B ∪ Ø implies b = B
