-2(x-4) + 4x < 18
Answer:
X<5
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
2x+8<18
Step 2: Subtract 8 from both sides.
2x+8−8<18−8
2x<10
Step 3: Divide both sides by 2.
2x/2
<
10/2
So in conclusion , x<5

Answer:
2.6 kilograms
Step-by-step explanation:
Tebow weighs 3.2 and Tiger weighs 4.5, so adding those numbers together...
3.2 + 4.5 = 7.7
-3 + 4 = 7
-0.2 + 0.5 = 0.7
-7 + 0.7 = 7.7
Bear weighs 10.3 kilograms.
10.3 - 7.7 = 2.6
10 - 7 = 3
Now you had the 0.3 to the whole 3.
3.3 - 0.7 = 2.6

Write the word sentence as an equation. Then solve.
A number x divided by −9 is −16.
Equation:
Solution: x=
Answer:
Solution: X=144
Equation: x/(-9)= -16
Step-by-step explanation:
the / is divide
the first part of the word problem states that a number x is being divided by -9, x/-9 then it states that this equation equals -16 therefore,x/-9=-16.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
x ÷ (-9) = -16
x = 144
The value of x is 144
What is an equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 7 is an equation.
2x8 + 4 ÷ 8 is an equation.
We have,
A number x divided by −9 is −16.
This can be written as,
x ÷ (-9) = -16
x/-9 = -16
-x/9 = -16
negative gets canceled.
x = 16 x 9
x = 144
Thus,
The value of x is 144

The net of a rectangular prism is shown below.
28624
What is the surface area of the rectangular prism?
Answer:
28
Step-by-step explanation:
Using a net to find the surface area of a rectangular prism
Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism.
For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units. From the net, we can see that there are six equal faces and so we get the total surface area is 6 × 16 = 96 square units.
Surface Area of a Rectangular Prism using Nets
A rectangular prism or cuboid is formed by folding a net as shown −
Cuboid
We can see from the net that there are two rectangles with dimensions 3 cm by 6 cm, two rectangles with dimensions 2 cm by 6 cm and two rectangles with dimensions 2 cm by 3 cm. The total surface area is then
2 × 3 × 6 + 2 × 2 × 6 + 2 × 2 × 3 = 72 cm2
Example 1:
Find the surface area of the given rectangular prism in square cm.
Rectangular Prism in Square cm
Solution
Step 1:
Using net, the surface area of a rectangular prism
= 2lw+wh+lh; l = 6 ; w = 5; h = 3
Step 2:
Surface area of given prism = 26×5+6×3+3×5
= 230+18+15
= 126 square cm
Example 2:
Find the surface area of the given rectangular prism in square cm.
Rectangular Prism Square cm
Solution
Step 1:
Using net, the surface area of a rectangular prism
= 2lw+wh+lh; l = 5; w = 6; h = 4
Step 2:
Surface area of given prism = 25×6+5×4+6×4
= 230+20+24
= 148 square cm
