Hey there!
Explanation:
First, you had to do is add by 13 from both sides of an equation.
Then, simplify or add by the numbers.
Next, you can also divide by 3 from both sides of an equation.
And finally, simplify and divide by the numbers,
*The answer must have a positive sign.*
Hope this helps!
Answer:
Step-by-step explanation:
So we would have to multiply the "2x - 8" by 5 each resulting in 10x - 40 + 15. Then we subtract which results in 10x - 25 = - 15. We add 25 to 25 and 15 resulting in 10x = 10. We divide each by 10 which results in x = 1.
The answer would be 560
8(7x5+7x4+7)
35+28+7
8x70
560
hope that helps
Answer:
Step-by-step explanation:
For sales of N copies at $90 each, 90N is added to Dale's base salary of $1800.
P = 90N +1800
__
For N=23, Dale's salary would be ...
P = 90(23) +1800 = 2070 +1800 = 3870
Dale's total pay for selling 23 copies would be $3870.
The sum of the external angles of a triangle taken one at each vertex is 360°, so
n = 360 - 160 - 131 = 69°
