How many solutions do these questions have? (WILL GIVE BRAINLIEST!)

1.) 2x-9y=-5

2.) 4x-6y=2

Answer:

jesse's mistake is in Step 1

Step-by-step explanation:

She had to subtract 9 from 11, which would have got her 2, for the part after the equal sign. However, she put 3, and 11-9 is not 3, so she is wrong.

Hope this helps!

Answer:

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h. Hence, to find the area of a tri-sided polygon, we have to know the base (b) and height (h) of it. It is applicable to all types of triangles, whether it is scalene, isosceles or equilateral. To be noted, the base and height of the triangle are perpendicular to each other. The unit of area is measured in square units (m2, cm2).

Answer:

Translate ABC to the right 2 units and down 4 units.

Step-by-step explanation:

Focus on how you count the squares, look at the blue triangle and then at the pink one. You count the A first to the right so it gets you the answer of 2 units to the right now count the same A and proceed to locate where the A' is so you count 4 squares as you get down to the A'. I hope this helped you understand (-_-;")

Answer:

1872 ft.²

Step-by-step explanation:

First lets figure out all of the easy shapes:

The bottom one: 8 * 7 = 56

The one on the left: 5 * 8 = 40

The one of top: 8 * 3 = 24

The slanted rectangle: 5 * 8 = 40

The small rectangle below that : 2 * 8 = 16

Now we just have the polygon facing toward us. It can be broken up into 2 parts:

The lower half: 2 * 7 = 14

Imagine a line going from the top of the line marked "2" straight across to the other side. That is the bottom half. Now we are left with a trapezoid. The formula for the area of a trapezoid is as follows:

A = ((a + b) / 2) * h

What this means is that we had the top and bottom of the figure, divide that by 2, and multiply it by the height. That can be shown here:

(3 + 7) / 2 = 5 * 3 = 15

15 is the area of the trapezoid. Now we can combine that with 14 to get the total area of the polygon:

14 + 15 = 29

Then do the same again for the other identical figure

14 + 15 = 29

Now we have all the areas of our shapes. Let's add them up:

56 + 40 + 24 + 40 + 16 + 29 + 29 = 234

234 is the total surface area of the box. Since there are 8 boxes, multiply this by 8 to get your final answer:

234 * 8 = 1872 ft.²

Don't forget to include units!

The solution is : 1872 ft.² of the new material is needed to build all 8 containers.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

given that,

Then do the same again for the other identical figure

14 + 15 = 29

Now we have all the areas of our shapes. Let's add them up:

56 + 40 + 24 + 40 + 16 + 29 + 29 = 234

234 is the total surface area of the box.

Since there are 8 boxes, multiply this by 8 to get your final answer:

234 * 8 = 1872 ft.²

if we take 4c to be the 100%, what is 0.2c off of it in percentage?

[tex]\begin{array}{ccll} a&b\\ \cline{1-2} 4c & 100\\ 0.2c& x \end{array} \implies \cfrac{4c}{0.2c}~~=~~\cfrac{100}{x}\implies \cfrac{4}{0.2}~~ = ~~\cfrac{100}{x} \\\\\\ 4x=20\implies x=\cfrac{20}{4}\implies x=5[/tex]

Answer:

84

Step-by-step explanation:

11 goes into 92 8 times

The first answer is 8

11*8 is 88

92-88 is 4

Carry down the 4 and make 44

11 goes into 44 four times

The second answer is 4

11*4 is 44

44-44 is 0

Please find attached the required new cereal boxes for the Yum Yum Cereal Company created with Microsoft Visio

Step-by-step explanation:

The required volume of the cereal box = 2,400 cm³

The box is to be drawn and labeled as follows using Microsoft Visio

Box #1 Length = 16 cm, Width = 15 cm, Height = 10 cm

The volume = Length × Width × Height = 16 cm × 15 cm × 10 cm = 2,400 cm³

Box #2 Length = 30 cm, Width = 10 cm, Height = 8 cm

The volume = Length × Width × Height = 30 cm × 10 cm × 8 cm = 2,400 cm³

and this is more simple Volume = (length width) height For example, the volume of the cereal box pictured is 312 cubic inches because V = (8 3) 13 = 312 cubic inches.
