Answer:

c = 8 is the answer

Step-by-step explanation:

9 = 1 + c

c = 9 - 1

c = 8

1/9 is the answer for that question

I thought it was 6/36 but I guess I was wrong

Answer:

about 5 rows

Step-by-step explanation:

14 divided by 3= 4.7 but since you can’t have 4.7 rows I rounded it to 5 rows. You can’t have 4 rows because then there would be 2 seeds remainin.

Answer:

Brittany can plant 4 rows and she will have 2 seeds left

Step-by-step explanation:

Fourteen divided by 3 will give you a mixed fraction.

So you can do 3*4= 12

If you do 14-12 you will get 2 seeds that remain.

Answer:

(x, y) = (3, 3)

Step-by-step explanation:

[tex]x - 2y = - 3 \\ 2x + 2y = 12 \\ [/tex]

To apply the method of elimination, you must add the 2 equation if one of the variables is cancelled out. Luckily, the equations are already in a form where we can add them and y will be cancelled out.

[tex](x - 2y) + (2x + 2y) = - 3 + 12[/tex]

[tex]3x = 9[/tex]

[tex]x = 3[/tex]

Then we replace x on any equation to find y

[tex]x - 2y = - 3 \\ 3 - 2y = - 3 \\ - 2y = - 6 \\ y = 3[/tex]

so the solution is

x = 3 and y = 3

Answer:

5200

Step-by-step explanation:

First solve 10^3 which will give you 1000 then multiply it by 1.7 to get 1700. Then multiple the answer for 10^3, which is 1000, by 3.5 to get 3500. The add the two answers together to get the answer. Which is 1700+3500=5200.

The answer is 15.7.

Step-by-step explanation:

Answer:

2. is x = -3

Step-by-step explanation:

-3( x - 3) = 12

multiply the things in the () by -3

-3x+9=12

subtract 9 from both sides

-3x+9-9=12-9

-3x=3

divide both sides of the equation by -3

x = -3

Answer:

1.  280.40

350.50*.20=70.10

350.50-70.10=280.40

2.x=−1

-3*3=--9+-3x

-3x/3= -1  x= -1

3.=15(3t−1)

Because 45t/15= 3 then 15/15=1

4.  =−0.8m+10

Let's simplify step-by-step.

3.5m+2−(4.3m−8)

Distribute the Negative Sign:

=3.5m+2+−1(4.3m−8)

=3.5m+2+−1(4.3m)+(−1)(−8)

=3.5m+2+−4.3m+8

Combine Like Terms:

=3.5m+2+−4.3m+8

=(3.5m+−4.3m)+(2+8)

=−0.8m+10

Answer:

=−0.8m+10

5.  Perimeter is adding all side sooo.22x -2

6x -2 + 6x-2=  12x - 4

5x +1 +5x+1= 10x+2

12x -4 +10 + 2= 22x -2

Answer:

Total surface = 102.4 cm^2 (second answer in the list of options)

Step-by-step explanation:

Notice that we need to add the surface of 4 rectangles, two have smaller sizes than the other two. A pair of rectangles are 7.2 cm x 4 cm = 28.8 cm^2, while the other pair has 7.2 cm x 2 cm = 14.4 cm^2

There are also two equal bases each one of size 4 cm x 2 cm = 8 cm^2

Now we add two of each of the individual surfaces discussed above to complete the total surface area:

2 * 28.8 + 2 * 14.4 + 2 * 8 =  102.4 cm^2

which agrees with the second answer option provided.

Answer:

I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.

Answer:

rise= -2 run= -4 slope= -1/2

Step-by-step explanation:

slope= rise/run

since rise=-2 and run=-4, slope=-2/4, but we have to simplify, so slope=-1/2

Step-by-step explanation:

No trapezoid is attached; so, I will solve on a general note

The area of a trapezoid is:

[tex]Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height[/tex]

Using the attached image as a point of reference;

The parallel sides are: AD (6cm) and BD (12cm)

The height is 4cm

So, the area is:

[tex]Area = \frac{1}{2} * (6cm + 12cm) * 4cm[/tex]

[tex]Area = 18cm * 2cm[/tex]

[tex]Area = 36cm^2[/tex]

Answer:

a<-2

Step-by-step explanation:

a < 1-3

a < -2

< does not have a line underneath so it'll be an open circle.

The arrow should be pointing to the right.

Answer:

x=5

Step-by-step explanation:

hey there

the angles given are corresponding angles meaning that they are congruent

so we set up an equation

23x-5=21x+5

step 1 subtract each side by 5

5-5 cancels out

-5-5=-10

now we have

23x-10=21x

step 2 subtract each side by 23x

21x-23x=-2x

now we have

-2x=-10

step 3 divide each side by 2

-10/-2=5

so we can conclude that

x=5

Answer:  pt=2667.1484≈2667

C, none of the above i believe

Answer:

It is D

Step-by-step explanation:

5 more than 3 times a number is less than 9/10

5   +                    3          (a)                <            9/10

Then just flip them

Answer:

x = 4

Step-by-step explanation:

7x - 3 = 5x + 5 --> 7x - 5x = 5 + 3 --> 2x = 8 --> x = 4.

You can check by substitute x = 4 back to the original equation.

Answer:

15.4

Step-by-step explanation

From the diagram, we are given;

Adjacent = 12

Hypotenuse=x

Angle of elevation =39°

Using the SOH CAH TOA identity

Cos 39 = 12/x

x = 12/cos39

x = 13/0.7771

x = 15.44

Hence the value of x to nearest tenth is 15.4
