Answer:

1 is 13/10 i believe and 2 will be 11/12

Step-by-step explanation:

heres my work

1 first find least common factor sense the denominators ar different witch will be ten then then the number you used to multiply the denominator to find 10 you use to multiply the numerator with.

so you left with 6/10 + 7/10 witch equals 13/10

2 do the same in 1 find least common factor witch is 12 and then multiply the number used to get the common factor by the numerator witch leaves the setup as 8/12+3/12 witch equals 11/12

Can i have Brainiest Please.

One counting number is 4 times great as a counting number.The product of the two number is 36.What is the sum of the two number
VARVARA [1.3K]

Answer:

The sum of the two numbers is 15

Step-by-step explanation:

Let the counting numbers be x and y.

Then we can write the following equations

x=4y.......1 (one is four times greater )

x(y)=36.....2 (the product of the two)

Putting equation 1 into equation 2, we get

4y(y)=36

{4y}^{2} = 36

Dividing through by 4,we get

{y}^{2} =  \frac{36}{4}

{y}^{2} = 9

Taking square root of both side, we obtain

y=3

Putting the value of y into equation , we get

x=4(3)=12

Hence the numbers are 3 and 12

Therefore the sum of the two numbers is 3+12=15

Answer:

D.

Step-by-step explanation:

In order to eliminate, the numbers must eliminate. If the second equation is multiplied by 3, then the 3 and the -3 can be eliminated. Since it is multiple choice, we can plug in x = 12 and y = 10 to see if they are correct. 12 + 30 = 42 and 24 - 10 = 14, so D is correct.

17. What are the three angle measures in the triangle shown below?
lianna [129]

Answer:

Option (1)

Step-by-step explanation:

By using triangle sum theorem in the given triangle,

(5x - 7)° + (11x - 4)° + (3x + 1)° = 180°

(5x + 11x + 3x) - (7 + 4 - 1) = 180

19x - 10 = 180

19x = 190

x = 10

Therefore, (3x + 1)° = 30 + 1

                                = 30°

(11x - 4)° = 110 - 4

              = 106°

(5x - 7)° = 43°

Therefore, Option (1) will be the correct option.

8=-4k

k=-2

so y=-2x

3.

eq.~of~line~is~y-4=\frac{4-4}{1+3} =\frac{0}{4} =0\\or~y=4\\or~y=0 x+4

4.

eq. of  line is y-5=4(x+2)
