Answer:

8

Step-by-step explanation:

first, we need to get rid of either one of the variables on either sides so that we have only one variable on one side to work with. to do this we add -2k to both sides to get rid of the variable on the right.

-5k+-2k+10=-2k+-2k-14.

this leaves you with:

-3k+10=-14.

now, we subtract 10 from each side to isolate the variable.

-3k+10-10=-14-10

from there we have -3k=-24.

in order to get rid of the coefficient attached to the variable, we use the division property of equality. thus, we divide each side by -3.

-3k/-3=-24/-3

and you should get,

<em>k= 8</em>

Charlotte is making 20 flower bouquets 4/5 of the bouquet are daisies and the rest are tulips how many bouquets are tulips
Annette [7]

Answer:

4 bouquets

Step-by-step explanation:

5/5 = 20 flower bouquets.

Find out how much flower bouquets there are when it's 1/5.

5/5 = 20

1/5 = 20 ÷ 5 = 4

Since tulips are 1/5 as 5/5 - 4/5 = 1/5, 4 bouquets are tulips.

Y = 5x + 7<br> 2x + y = -5<br> Are the equations parallel,<br> perpendicular, or neither?
Nezavi [6.7K]

Lines are neither perpendicular nor parallel.

Step-by-step explanation:

Step 1:

In equation 1, Y = 5X + 7

In equation 2,  Y = -2X -5

Step 2:

Slope Intercept form Y =mX +c

Where m = Slope

Slope of line 1 = 5

Slope of line 2 = -2

m1  is not equal to m2. Hence it is not parallel.

m1  × m2 is not equal to -1. Hence they are not perpendicular.

Help me please with my math
motikmotik

Answer:

P = 47.1 units

Step-by-step explanation:

the perimeter of the pair of straight opposite sides is 11+11, or 22

now you have 2 semi-circles, which equals 1 full circle which, if we find the circumference to then we just add it to 22 to get the entire answer

Circumference of circle with diameter of 8:

C = 2πr

C = 2π(4)

C = 8π

C = 25.13

now add 22 + 25.13 to get 47.1 rounded to nearest tenths place
