Answer:

1. Rewriting the expression 5.a.b.b.5.c.a.b.5.b using exponents we get: \mathbf{5^3a^2b^4c}

5.  x^-6 = \frac{1}{x^6}

6. 5^{-3}.3^{-1}=\frac{1}{5^3.3^1}

7. a^{-3}b^0c^4=\frac{c^4}{a^3}

Step-by-step explanation:

Question 1:

We need to rewrite the expression using exponents

5.a.b.b.5.c.a.b.5.b

We will first combine the like terms

5.5.5.a.a.b.b.b.b.c

Now, if we have 5.5.5 we can write it in exponent as: =5^{1+1+1}=5^3

a.a as a^{1+1}=a^2

b.b.b.b as: b^{1+1+1+1}=b^4

So, our result will be:

5^3a^2b^4c

Rewriting the expression 5.a.b.b.5.c.a.b.5.b using exponents we get: \mathbf{5^3a^2b^4c}

Question:

Rewrite using positive exponent:

The rule used here will be: a^{-1}=\frac{1}{a^1} which states that if we need to make exponent positive, we will take it to the denominator.

Applying thee above rule for getting the answers:

5) x^{-6} = \frac{1}{x^6}

6) 5^{-3}.3^{-1}=\frac{1}{5^3.3^1}

7) a^{-3}b^0c^4=\frac{b^0c^4}{a^3}

We know that b^0=1 so, we get

a^{-3}b^0c^4=\frac{b^0c^4}{a^3}=\frac{c^4}{a^3}

Each sheep has 4 legs and each chicken has 2 legs.if a farm boy counts 50 heads and 130 feet, how many sheep are there
slavikrds [6]

Answer:

15 sheep

Step-by-step explanation:

1 leg = 1 foot

1 head = 1 animal

Suppose all the animals are chickens:

50 × 2 = 100

130 - 100 = 30

4 - 2 = 2

30 ÷ 2 = 15

Hence, there are 15 sheep.

Help???<br> Its a two step inequality problem. I dunno what X equals too.
Verizon [17]

Answer:

x \geq -1

Step-by-step explanation:

-4x + 2 \geq -6x

Add 6x to both sides:

-4x + 2 + 6x \geq -6x + 6x

2x + 2 \geq 0

Subtract 2 from both sides:

2x + 2 - 2 \geq 0 - 2

2x \geq -2

Divide both side by 2:

\frac{2x}{2} \geq \frac{-2}{2}

x \geq -1
