4(7-x) = 5(x+2)
you would give 4 and 5 to everything in the parenthesis
28-4x = 5x+10
then subtract 10 on each side
28-4x = 5x+10
-10 -10
18-4x = 5x
then add 4x on each side
18-4x = 5x
+4x +4x
18 = 9x
x = 2

<em>ANSWER:</em>

<h2>x=2</h2>

<em>STEP:</em>

Multiply the parenthesis by the number before.

28-4x=5x+10

Add 4x to both sides.

28-4x=5x+10

28=9x+10

Subtract 10 from both sides.

18=9x

Divide both sides by 9.

2=x

Please help me find the perimeter.​
slavikrds [6]

Answer:

31.42 cm (rounded up to two decimal places)

Step-by-step explanation:

We first find the circumference of the semi-circle segment:

The circumference will be given by; \frac{1}{2} × π × D (where D is the diameter)

The diameter is 6 cm so circumference is;

\frac{1}{2} × π × 6 cm = 9.42 cm (rounded up to two decimal places)

The perimeter of the figure therefore is;

8cm + 6 cm + 8 cm + 9.42 cm = 31.42 cm

20 units Humulin R insulin in 100 mL of normal saline (NS) to infuse for 20 hours. (Round to the nearest tenth if applicable) a.
wariber [46]

Answer:

a) 1 unit per hour will be infused.

b) 5mL per hour will be infused.

Step-by-step explanation:

Each question can be solved as a rule of three with direct measures, that means we have a cross multiplication.

a. How many units per hour will be infused?

20 units are going to be infused in 20 hours. How many units are going to be infused each hour?

1 hour - x units

20 hours - 20 units

20x = 20

x = \frac{20}{20}

x = 1

1 unit per hour will be infused.

b. How many milliliters per hour will be infused?

100mL are going to be infused in 20 hours. How many mL are going to be infused each hour?

1 hour - x mL

20 hours - 100 mL

20x = 100

x = \frac{100}{20}

x = 5

5mL per hour will be infused.

Which is the approximate solution for the system of equations 3x+4y=2 and 4x+y=-4
harina [27]

3x+4y=2\qquad\text{subtract 3x from both sides}\\\\4y=-3x+2\qquad\text{divide both sides by 4}\\\\y=-\dfrac{3}{4}x+\dfrac{2}{4}\to y=-\dfrac{3}{4}x+\dfrac{1}{2}\\\\for\ x=0\to y=-\dfrac{3}{4}(0)+\dfrac{1}{2}=0+\dfrac{1}{2}=\dfrac{1}{2}\to\left(0,\ \dfrac{1}{2}\right)\\\\for\ x=2\to y=-\dfrac{3}{4}(2)+\dfrac{1}{2}=-\dfrac{3}{2}+\dfrac{1}{2}=-\dfrac{2}{2}=-1\to(2,\ -1)\\--------------------------------\\

4x+y=-4\qquad\text{subtract 4x from both sides}\\\\y=-4x-4\\\\for\ x=0\to y=-4(0)-4=0-4=-4\to(0,\ -4)\\\\for\ x=-1\to y=-4(-1)-4=4-4=0\to(-1,\ 0)\\\\Answer:\ \boxed{A.\ (-1.4,\ 1.5)}
