18) Value of b is : $b\geq 8$

Option A is correct.

19) Option C is correct.

Step-by-step explanation:

18) We need to find the value of b.

The given equation is:

$12b-46\geq 50$

Solving to find the value of b:

$12b-46\geq 50\\12b\geq 50+46\\12b\geq 96\\b\geq \frac{96}{12}\\b\geq 8$

So value of b is : $b\geq 8$

Option A is correct.

19) We need to find the correct graph of the equation:

$4y-2$

Solving:

$4y-2$

The values of y will be less than three. As y < 3 so, the circle on y is not filled.

So. Option C is correct.

What is 6.34 when the 34 is repeating as a fraction

lana [24]

ANSWER:

6_34/99

STEP:

So yes. When a decimal is repeating, you can take the repeating number (most likely a decimal) and put 99 under it. Since 99 cannot be solved, you put 99. So, 34/99. Though we are not finished. There is still the whole 6 number left. So, you do 6_34/99.

Proof:

10x=6.6...

-x=-0.6...

9x=6

x=6/9=1/3.

Simplify the expression. Write your answer using only positive exponents. Evaluate any numerical powers.

gtnhenbr [62]

Answer:

9x⁵

Step-by-step explanation:

Use properties of exponents:

$a^{b} a^{c} = a^{b+c}$ , $(a^{b} ^)^{c} = a^{bc}$ , $1/a^{-b} = a^{b}$

Simplify the given expression:

3⁴⋅x⋅(3/x²)⁻² =
3⁴·x·(3x⁻²)⁻² =
3⁴·x·(3⁻²)(x⁻²ˣ⁻²) =
3⁴⁻²·x¹⁺4 =
3²·x⁵ =
9x⁵

Henry's patio is in the shape of a rectangle. He said the perimeter of the patio is 48 feet . He knows that one side is 9 feet w

ss7ja [257]

Answer:

2 sides of the patio are 9ft and another 2 sides are 15ft

Step-by-step explanation:

To solve this problem we have to know thata rectangle has 4 sides and 2 of them are equal to each other

This is the formula to calculate perimeter

p = perimeter 48 ft

a = side a = 9 ft

b = side b

p = 2a + 2b

we replace the known values

48ft = 2*9ft + 2b

48ft = 18ft + 2b

48ft - 18ft = 2b

30 / 2 = b

15 = b

2 sides of the patio are 9ft and another 2 sides are 15ft
