Answer:

∠DGB = 101°

Step-by-step explanation:

Given:

∠CGB = 79°

Find:

∠DGB

Computation:

We know that CD is a straight line

So,

∠CGB + ∠DGB = 180

79 + ∠DGB = 180

∠DGB = 101°

Answer:

2 hours

Step-by-step explanation:

To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:

5.5 - 3.5 = 2.0

Meaning, Sara has 2 hours left to drive

Hope this helps :)

Answer:

x*2=y+x= both

Step-by-step explanation:

y would be her sister age, you would have to multiply Marias age by 2 to get her sisters age since her sister is twice her age then you have to add them together to get the sum of both their ages.

Example: maria is 16

               16*2=32+16=48

           so the sum of both of their ages is 48 (JUST AN EXAMPLE)

Answer:

you got to go back to the question before that and then you will know.

Answer:

(45,9), (50, 14)

Step-by-step explanation:

the y-axis' pattern is subtract 2 and add 5.

the x-axis' pattern is add 7 then add 5.

So we get (45, 9) and (50, 14)

if my answer helped please mark as brainliest.

Answer:The answer is going to be 3 and this is how we came to that determination:

We are to subtract 3 times the number from 7 times the number and have it equal 12. So here is the the mathematical sentence to help us get the answer:

7X-3X=12 ; now we are going to subtract the 3 from the 7 on the left hand side of the equal sign:

4X=12 ; now we will divide each side of the equal sign by 4:

4X/4=12/4 and get X =3 ; to prove 3 is the number we are looking for, we will substitute it for X in our original sentence:

7(3)-3(3)=12

21–9=12

12=12

3 is our answer.

Answer:

There's a proportion relationship between number of shell and their cost

Step-by-step explanation:

The graph is not given.

However, I've added the appropriate graph as an attachment.

From this, point....

I'll show that the cost and number of shells as given in the question are proportional.

Represent cost with y and number of shells with x

x = 2 when y = 0.8

x = 3 when y = 1.2

x = 4 when y = 1.6

Divide each value of y by x to get the constant of proportion (r).

r = y/x

r = 0.8/2 = 0.4

r = 1.2/3 = 0.4

r = 1.6/4 = 0.4

Notice that the values of r remain constant.

Hence, there's a proportion relationship between both

And what this rate represent is that:.the cost of shell changes at a constant rate when the number of shell is changes.

x = 5.29

Step-by-step explanation:

24x = 127

Divide both sides by 24.

x = 127/24

x = 5.29

4  7 /32

Step-by-step explanation:

135 : 32 = 4 ( 7)

Kết quả:  

135 /32

= 4  7 /32

Answer:

[tex]4\frac{7}{32}[/tex]

Step-by-step explanation:

Given the mixed numbers:

[tex]1\frac{1}{4}[/tex],[tex]1\frac{1}{2}[/tex],[tex]2\frac{1}{4}[/tex]

First, we need to convert them into improper fractions of the denominator of 4.

1 1/4 = 5/4

1 2/4 = 6/4

2 1/4 = 9/4

So we multiply 1 1/4 x 1 2/4 x 2 1/4 which gets us 4 7/32

Answer:

Area = 396 units²

Step-by-step explanation:

Let's assume:

Length = 2c - 5

Width = 5c + 9

Perimeter = 2(L + W) = 106 units

Thus:

2[(2c - 5) + (5c + 9)] = 106

Find the value of c

2[2c - 5 + 5c + 9] = 106

2[7c + 4] = 106

14c + 8 = 106

14c = 106 - 8

14c = 98

Divide both sides by 14

c = 98/14

c = 7

✔️Area of the rectangle = Length × Width

Area = (2c - 5)(5c + 9)

Plug in the value of c

Area = (2×7 - 5)(5×7 + 9)

Area = (14 - 5)(35 + 9)

Area = (9)(44)

Area = 396 units²

Answer:22

Step-by-step explanation:

Answer:

Step-by-step explanation:

let x be chickens and y be cows

x+y=15

x=15-y

2x+4y=44, using x=15-y

2(15-y)+4y=44

30-2y+4y=44

2y+30=44

2y=14

y=7, since x=15-y

x=8

So there are 8 chickens and 7 cows.
