Which expressions are equivalent to -56z+28−56z+28minus, 56, z, plus, 28?

bearhunter [10]

Answer:

B) $(-1.4z+0.7)\times 40$

D) $(8z-4)(-7)$

Step-by-step explanation:

Given expression:

$-56z+28$

To find the equivalent expression.

We will evaluate each expression in the given choices to check the equivalence.

A) $\frac{1}{2}(-28x+14)$

Using distribution.

⇒ $\frac{-28z}{2}+\frac{14}{2}$

⇒ $-14z+7$

B) $(-1.4z+0.7)\times 40$

Using distribution.

⇒ $(-1.4z\times 40)+(0.7\times 40)$

⇒ $-56z+28$

C) $(14-7z).(-4)$

Using distribution.

⇒ $(14.(-4))+(-7z.(-4))$

⇒ $-56+28z$

D) $(8z-4)(-7)$

Using distribution.

⇒ $(8z(-7))+(-4(-7))$

⇒ $-56z+28$

E) $-2(-28z-14)$

Using distribution.

⇒ $(-2(-28z))+(-2(-14))$

⇒ $56z+28$

From the choices evaluated, we find that the expressions in choices B and D are equivalent

An actor invests some money at 7%, and $48000 and more than twotimes the amount of 9%. The total annual interest earned from the

forsale [732]

Answer:

At 7% $54,000

At 9% $156,000

Step-by-step explanation:

Let x be the amount invested at 7%, Then 2x + 48000 will be the amount invested at 9%

We know that:

7% = 0.07 & 9% = 0.09

So we can write the interest equation as follows:

0.07x + 0.09 (2x + 48000) = 17820

0.07x + 0.18x + 4320 = 17820

0.25x + 4320 = 17820

Subtracting 4320 from both sides of the equation we get:

0.25x = 17820 - 4320

0.25x = 13500

Dividing both sides of the equation by 0.25 we get:

x = 13500 / 0.25

x = $54,000 invested at 7%

2 x 54000 + 48000

= $156,000 invested at 9%

Hence the amount invested at 7% is $54,000.

& the amount invested at 9% is $156,000.

Dwight is making accessories for the soccer team. He uses 648.62 inches of fabric on headbands for 39 players and 2 coaches. He

krek1111 [17]

Answer:

24.33 inches

Step-by-step explanation:

inches of fabric on headbands = 648.62 inches

39 players and 2 couches = 41 people

Inches of fabrics per person = Total headbands inches / number of people

= 648.62 inches / 41

= 15.82 inches per person

Inches of fabrics used for headbands per person = 15.82 inches

inches of fabric on wristbands = 331.89 inches

Used for players alone

Inches of fabrics for wristband pee person = Total inches of fabrics for wristband / number of people

= 331.89 inches / 39 players

= 8.51 inches

Inches of fabrics used for wristband per person = 15.82 inches

How much fabric was used on a headband and wristband for each player?

= Inches of fabrics used for headbands per person + Inches of fabrics used for wristband per person

= 15.82 inches + 8.51 inches

= 24.33 inches

Inches of fabrics used on headband and wristband for each player is 24.33 inches
