Answer:

Solution given:

5(9x-8)=4(x+2)

45x-40=4x+8

45x-4x=40+8

41x=48

x= $\frac{48}{41}$

Gabriella is not correct:

she has done in distribution 

5(9x-8)=4(x+2)

45x-40=4x+8 not 45x-8=4x+2.

Darryl’s credit card has a minimum monthly payment of 2.51% of the card’s balance.
Darryl currently owes $1,431.72. Let's solve his minimum payment.
=> 1,431.72 * 0.0251 = 35.94 dollars
=> 1,431.72 + 35.94 dollars = 1467.656172 or 1467.7 dollars.

Find the slope of the line through each pair of points(-13,-18),(0.-17)

Jet001 [13]

The slope formula is

=2−1/2−1

For the first one it would be:

-17-(-18)/0-(-13)=1/13

m=1/13

Second one:

m=−16−−9/−17−−18= -7/1

m=-7

For the there one:

Slope =−12−−13/6−−1=1/7

m=1/7

I hope it was helpful. If you have any questions let me know.

Help please!!!!!! 12-13 8th grade math!!!

marin [14]

Answer:

12.

m∠ACB = 180° - 58° - 78° = 44°

m∠DCE = 180° - 85° - 60° = 35°

m∠BCD = 180° - 44° - 35° = 101°

13.

Base on the picture, we know that:

x° + 2x° + 3x° = 180°

6x° = 180°

x° = 180° ÷ 6 = 30°

=> m∠K = 2x° = 2 × 30° = 60°

=> m∠L = 3x° = 3 × 30° = 90°

=> m∠KML = x° = 30°

m∠LMN = 60° + 90° = 150°
