Answer:

Quantity (lbs) of type 1 candy x = 8

Quantity (lbs) of type 2 candy y = 17,5

Step-by-step explanation:

Let´s call "x" quantity (in pounds) of candy type 1 in the mixture, and "y" quantity (in pounds ) of candy type 2, then according to the problem statement.

x + y = 25,5

2,20*x + 7,30*y = 5,70 * 25,5 ⇒ 2,20*x + 7,30*y = 145,35

Then we have a two equation system

x + y = 25,5 ⇒ y = 25,5 - x

2,20*x + 7,30*y = 145,35 ⇒ 2,20*x + 7,30* (25,5 - x ) = 145,35

2,20*x + 186,15 - 7,30*x = 145,35

5,1*x = 40,8

x = 40,8/5,1

x = 8 lbs

And y = 25,5 - 8

y = 17,5 lbs

How do you do question number 5? If you do it can you please explain how to do it? Thank you!!

F(-3) = 4(-3) - 3 = -12 - 3 = -15.
H(2) = -5(2) + 7 = -10 + 7 = -3.

F(-3) + H(2) = -15 + -3 = -18.

The solution is -18.

PLEASE HELP

Answer: B. 1/2(y - 116) = 64

Step-by-step explanation:

Since, we know that,

The angle formed by two tangent = $\frac{1}{2}(\text{Difference of intercepted Arcs} )$

= $\frac{\text{major arc - minor arc}}{2}$

Here, Major arc = y°

Minor arc = 116°

And, Angle made by two tangents YX and YZ,

$m\angle XYZ = \frac{\text{y - 116}}{2}$

$64 = \frac{\text{y - 116}}{2}$ ( because, $m\angle XYZ = 64^{\circ}$ )

⇒ $\frac{\text{y - 116}}{2} = 64$

Which is the required equation to find y, the measure of XWZ.

Thus, Option B is correct.

Answer:

x=−12

Step-by-step explanation:

Let's solve your equation step-by-step.

7(x+3)=5x−3

Step 1: Simplify both sides of the equation.

7(x+3)=5x−3

(7)(x)+(7)(3)=5x+−3(Distribute)

7x+21=5x+−3

7x+21=5x−3

Step 2: Subtract 5x from both sides.

7x+21−5x=5x−3−5x

2x+21=−3

Step 3: Subtract 21 from both sides.

2x+21−21=−3−21

2x=−24

Step 4: Divide both sides by 2.

−24

x=−12

Answer:

x=−12
