Answer:

Step-by-step explanation:

We have two squares of 4x4 units and 4 rectangles of 4x2 units, therefore

$2 \cdot (4 \cdot 4)= 2 \cdot 16 = 32 \text{ squre units}$

$4 \cdot (4 \cdot 2)= 4 \cdot 8 = 32 \text{ squre units}$

Total Area is therefore 32 + 32 = 64 square units

Divide a salad with six friends, 1/3 is missing, how much does each person get?

Talja [164]

Each friend gets 1/9. If you have 1 salad and 1/3 is missing that leaves you with 2/3, you have 6 friends and I am assuming they each get an equal amount so 2/3 equals 4/6, 4/6 equals 6/9, there are 6 people, they each get 1/9.

Answer:

● $\displaystyle 1$

Step-by-step explanation:

According to the Definition of Rational Exponents [part I], you can rewrite radicals as exponents:

$\displaystyle a^{\frac{m}{n}} = \sqrt[n]{a}^m \\ \\ \sqrt{y^2} = y, where\:any\:invisible\:exponent\:is\:ALWAYS\:1$

(2x+1)/2=(x+2)/5<br><br>if possible can you show me step by step how to get the answer <br>

katrin2010 [14]

Answer:

$\boxed{\bold{Decimal \ Form: \ x \ = \ -0.125}}$

$\boxed{\bold{Fraction \ Form:x=-\frac{1}{8}}}$

Step By Step Explanation:

Apply Fraction Cross Multiply: If $\bold{\frac{a}{b}=\frac{c}{d}:then\ a\cdot \:d=b\cdot \:c}$

$\bold{\left(2x+1\right)\cdot \:5=2\left(x+2\right)}$

$\bold{\left(2x+1\right)\cdot \:5: \ 10x+5}$

$\bold{2\left(x+2\right): \ 2x+4}$

$\bold{10x+5=2x+4}$

Subtract 4 From Both Sides

$\bold{10x+5-5=2x+4-5}$

Simplify

$\bold{10x=2x-1}$

Subtract 2x From Both Sides

$\bold{10x-2x=2x-1-2x}$

Simplify

$\bold{8x=-1}$

Divide Both Sides By 8

$\bold{\frac{8x}{8}=\frac{-1}{8}}$

Simplify

$\bold{x=-\frac{1}{8}}$

Turn Fraction Into Decimal

$\bold{-1 \ \div \ 8 \ = \ -0.125}$

$\bold{-0.125}$

After you add both sides by 9. How can you solve for 5z in this equation <br> 5z-3=12

lutik1710 [3]

Answer:

OPTION A: Divide both the sides by 5

Step-by-step explanation:

We are given: 5z - 3 = 12

When we add 9 to both sides we get:

5z - 3 + 9 = 12 + 9

⇒ 5z + 6 = 21

⇒ 5z = 21 - 6 = 15

⇒ 5z = 15

To find the value of z we have to divide both the sides by 5.

i.e., $\frac{5z}{5} = \frac{15}{5}$

⇒ z = 3.
