Murljashka [212]3 years ago
6 0

Answer:

i believe its the second part thats wrong  

Step-by-step explanation:

1 Distribute

−5(−2+10)=20

10−50=20

2 Add 50 to both sides of the equation

10−50=20

10−50+50=20+50

3 Simplify

Add the numbers

10x−50+50=20+50

10=20+50

Add the numbers

10x =20 + 50

10x=10

4 Divide both sides of the equation by the same term

10x = 70

10x   70

---- = ----

10      10

5 Simplify

Cancel terms that are in both the numerator and denominator

10x   70

---- = ----

10      10

      70

x  = ----

       10

   

        70

x  = ----

       10  

x=7

Solution

= 7

A cylindrical container of five rubber balls has a height of 30 centimeters and a diameter of 6 centimeters. Each ball in the co
Artyom0805 [142]

Answer:

There is 170 cm³ free space in the container.

Step-by-step explanation:

Cylindrical container: height = 18 cm ; diameter = 6 cm.

3 balls each have a radius of 3 cm.

Volume of a cylinder = π r² h

V = 3.14 * (3cm)² * 18 cm

V = 508.68 cm³

Volume of rubber ball = 4/3  π r³

V = 4/3 * 3.14 * (3cm)³

V = 113.04 cm³

113.04 cm³  * 3 balls = 339.12 cm³

508.68 cm³ - 339.12 cm³ = 169.56 cm³ or 170 cm³

Solve 3x+2y=4 4x+3y=7 algebraically
Leona [35]
Step 1. Multiply first equation with -3 and the second one with 2. You'll get:
\left \{ {{-9x-6y=-12} \atop {8x+6y=14}} \right.

Step 2. Add both equations together. You'll get:
-x=2, which gives x = -2

Step 3. Replace x = -2 in the first equation and calculate y.
3(-2)+2y=4\\
y=\frac{4+6}{2}=5

The solution is: x=-2, y=5
