What is the solution to this system of linear equations

Answer:

Yes, it will still be 27? So, like 27 + 27 = DBC.

Answer:

54

Step-by-step explanation:

Bisecting means to divide in half

<1  = <2

If <2 = 27 , then <1 = 27

The sum of the angle = 27+27 = 54

If DBC is the original angle, then DBC = 54

Answer:

$7.47

Step-by-step explanation:

Since a 8-ounce salad cost 2.49

You do 2.49+1 pound times 0.25

1 pound equals to 16 ounces

2.49 + 2.49 + 2.49

Correct. If I am wrong

Answer:

Step-by-step explanation:

the base is 2.49 for eight ozs so you already take off the ozs from 1 pound

since there are 16 ounces in one pound you multiply 16 by .25 and get 4 so you add 2.49 and 4 to get 6.49$ is the answer assuming there is no tax on the food

Answer:

V = 5(12)(7) which is F.

Step-by-step explanation:

V = LWH

L = 12

W = 5

H = 7

12 * 5 * 7

Answer:

if you need to find the area, the answer is 420, I think All in all the answer is F <last one>

Step-by-step explanation:

I think the first thing you do is L x W (12 x 5), which is 60. Then you do 60 x H (60 x 7), and you will get 420.

I am not entirely sure if I got it right.

Solve each equation to see if the left side equals the right side.

The answer would be C because when solved it becomes -4 = -8 which is false.

Answer:

[tex]x = 42[/tex]

Step-by-step explanation:

Given

The diagram above

Required

Find x

When two parallel lines are divided in such a way as it is in the above figure;

x and 138 are said to be supplementary angles

The rule about supplementary angles is that, they add up to 180

In other words,

[tex]x + 138 = 180[/tex]

To solve this, we subtract 138 from both sides

[tex]x + 138 - 138= 180 - 138[/tex]

[tex]x = 180 - 138[/tex]

[tex]x = 42[/tex]

Hence, the value of x when solved using the properties of parallel lines is: [tex]x = 42[/tex]

Step-by-step explanation:

Answer:

a + b = 1 or 4

Step-by-step explanation:

The integer = 3a5b

The factors of the integer includes 5 and 6

∴ 5 × 6 = 30 is a factor of the integer hence 10 is also a factor which gives b = 0

We check for factors of four digit numbers with the first digit = 3, last digit = 0, penultimate to the last digit = 5 and divisible by 30

We have a50 divisible by 30, which gives, a5 divisible by 3 which includes

15 and 45 hence a can be 1 or 4 and a + b = 1 + 0 = 1 or  4 + 0 = 4.

Step-by-step explanation:

circumference is pi x diameter since this is a semi circle you then divide it by 2

so if you work backwards 110x2 = 220 divided by pi

then you get the diameter and divide it by 2 to find the radius

Answer:

3.26

Step-by-step explanation:

Rounding to the nearest hundredth means round to the nearest two decimal places.

To do this, all we need to look at is the 3rd decimal place.

Since 4 is not 5 or greater, that means we must round down, no matter how close it is to 5.

Therefore, the answer should just be 3.26

Answer:

3.26

Step-by-step explanation:

You round the second place after the decimal (6) by the place after it (4).

If the place after the number you need to round is a 5 or up, the decimal you round goes up one, if it is a 4 or lower it stays the same.

E.G. if 3.2649 was 3.2659 the hundreds would be rounded to 3.27. Since it's a 4, the six stays the same at 3.26.]

Odyssey ware Answer: 9 = 3 x 3 x 3

Step-by-step explanation:

If the volume of the box is 9. The possible side lenths are:

V = L x W x H

9 = 3 x 3 x 3.

What I did was estimated how 9 could be split up into 3 so that it’ll make sense for L x W x H.

Answer:

[tex]5\[/tex]

Step-by-step explanation:

Let x be cost of 1 eraser.

[tex]5 +4x=25[/tex]

[tex]4x=20[/tex]

[tex]x=5[/tex]

Answer:

The buyer bought four erasers and a magazine for $25.

The cost of each magazine is $5

The cost of an eraser is x dollars

The cost of 4 erasers is 4x

Step-by-step explanation:

Cost of the Erasers + Cost of the Magazine = Total Cost

4x + $5 = $25

Subtract 5 from both sides to isolate the term with the variable.

4x + 5 -5 = 25 -5

4x = 20

The last thing you do is you divide it by 4 on both sides to isolate the variable.

x = 20/4 = $5

Answer:

28.13 cm

Step-by-step explanation:

The first step we need to do is create the segment AC.

Then, we can find its length using the law of cosines in the triangle ABC:

b^2 = a^2 + c^2 - 2*a*c*cos(B)

b^2 = 8^2 + 6^2 - 2*8*6*cos(95)

b^2 = 64 + 36 - 96*(-0.0872)

b^2 = 108.37

b = 10.41 cm

Then, in the triangle ADC, we can use the Pythagoras' theorem to find the length of DC:

DC^2 + DA^2 = AC^2

DC^2 + 25 = 108.37

DC^2 = 83.37

DC = 9.13 cm

So the perimeter of ABCD is:

Perimeter = AB + BC + CD + DA

Perimeter = 6 + 8 + 9.13 + 5 = 28.13 cm

Answer:

The perimeter of the shape is 28.13 cm

Step-by-step explanation:

First of all, we will have to draw a line from point A to point C. This will divide the shape into two parts, both of which are triangles.

We will use the dimensions of the newly formed triangle ABC to get the side AC.

The cosine formula will be apt for this purpose:

[tex]AC^{2}=AB^{2}+BC^{2}-(2 \times AB\times BC\times cos \theta)[/tex]

[tex]AC^{2}=6^{2}+8^{2}-(2 \times 6\times 8\times cos( 95))=108.37[/tex]

[tex]AC=\sqrt{108.37}=10.41 cm[/tex]

Now we have AC as 10.41 cm,

we can see that AC forms the hypothenuse of the right-angled triangle ADC.

From Pythagoras' theorem,  DC can be calculated as

[tex]DC =\sqrt{AC^{2}- AD^{2}}[/tex]

[tex]DC =\sqrt{10.41^{2}- 5^{2}}= 9.13 cm[/tex]

Therefore the perimeter of the shape is 8 + 5 + 9.13 + 6 =28.13 cm

The perimeter of the shape is 28.13 cm
