Answer:

It's A.

Step-by-step explanation:

5x2 + 60x = 0

5x is the GCF so:

5x(x + 12 ) = 0

5x = 0, x + 12 = 0

x =0, x = -12.

Answer:

The correct option is 1.

Step-by-step explanation:

The given quadratic equation is

$5x^2+60x=0$

Taking out the common factors.

$5x(x+12)=0$

Using zero product property, equate each factor equal to 0.

$5x=0\Rightarrow x=0$

$x+12=0\Rightarrow x=-12$

The solutions of the given equations are x=0 and x=-12.

Therefore the correct option is 1.

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (18, 0)

Point (10, -5)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{-5-0}{10-18}$
Subtract: $m=\frac{-5}{-8}$
Simplify: $m=\frac{5}{8}$

Malcom is filling bags with rice . He starts with a 5 1/4 pound container of rice and fills each bag with 5/8 pounds of rice . H

timama [110]

Answer:

Malcolm would fill 8 bags of rice.

Step-by-step explanation:

The size of the container of rice = 5 $\frac{1}{4}$ pounds = $\frac{21}{4}$ pounds.

Each bag of rice has a capacity of $\frac{5}{8}$ pounds.

The number of bags of rice that Malcolm fills = $\frac{total quantity of rice}{capacity of each bag}$

= $\frac{21}{4}$ ÷ $\frac{5}{8}$

= $\frac{21}{4}$ x $\frac{8}{5}$

= $\frac{42}{5}$

= 8 $\frac{2}{5}$

Therefore, Malcolm would be able to fill 8 bags of rice.

Answer:

Step-by-step explanation:

Statements Reasons

----------------------------------------------------------------

1. ∠V ≅ ∠Y Given

2. WZ bisects ∠VWY Given

3. ∠VWZ ≅ ∠YWZ Definition of Angle Bisector (2)

4. WZ ≅ WZ Reflexive Property

5. ΔVWZ ≅ ΔYWZ AAS Theorem (1,3,4)

**In case you didn't know the definitions**

Angle Bisector - A line, segment or ray that divides an angle into two congruent angles

Reflexive Property - X = X

AAS Postulate - If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangle's are congruent

a repair bill for your car is 553. the parts cost 265. the labor cost is 48 per hour write and solve an equation to find the num

Effectus [21]

Let's represent the number of hours with the variable 'h' (or whatever letter you want it to be):

265 + 48h = 553

Substract both sides by 265:

48h = 288

Divide:

h = 6

6 hours of labor was spent
