Answer:

A: x = -4

Step-by-step explanation:

Remove Parentheses:

8x - 3 = 10x + 5

Move terms

8x - 10x - 3 = 5

8x - 10x = 5 + 3

Collect Like Terms

-2x = 5 + 3

-2x = 8

Divide

-2x = 8

x = -4

Answer

x = - 4

Answer:

B is the answer

Step-by-step explanation:

A = πr²

24π = πr²

24 = r²

$\sqrt{24}$ = r

r = $\sqrt{4}$ $\sqrt{6}$ = 2 $\sqrt{6}$

C = 2πr

C = 2π(2 $\sqrt{6}$ )

C = 4 $\sqrt{6}$ π

What is the length of side BC of the triangle? Enter your answer in the box. units Triangle A B C with horizontal side B C. Vert

harina [27]

Answer:

The length of BC = 28 units

Step-by-step explanation:

* In triangle ABC

∵ Angles B and C are congruent

∴ m∠B = m∠C

* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length

∴ AB = AC

∵ AB = 4x - 7

∵ AC = 2x + 7

∴ 4x - 7 = 2x + 7 ⇒ collect like terms

∴ 4x - 2x = 7 + 7

∴ 2x = 14 ⇒ divide both sides by 2

∴ x = 14 ÷ 2 = 7

* Now we can find the length of BC

∵ The length of BC = 4x ⇒ substitute the value of x

∴ The length of BC = 4 × 7 = 28 units

the size of a red blood cell is 0.000007m and that of a plant cell is 0.00001265m show that a red blood cell is half of a plant

Readme [11.4K]

ANSWER: The size of a red blood cell IS approximately half the size of a plant cell.

EXPLANATION:

1. We divide the size of the plant cell by 2 to see if half of its size is the size of a red blood cell.

$\frac{0.00001265}{2} = 0.000006325 m$

Therefore, half of a plant cell's size is 0.000006325 m.

2. We now compare the size of half of the plant cell to the size of the red blood cell.

0.000006325 m and 0.000007 m are very close in size; therefore, the size of a red blood cell IS approximately half of a plant cell.
