.65
13/20
Just simply divide and you get .65
Let's break it down quick
since (8*5) is in parenthesis, you have to do it first which would equal 40. 10*2=20*8 is 160. Since there is a negative in between that and 3*40 you must solve 3*40 first, which equals 120. Now,
160-120= 40
The answer to the question is 40.
Answer:
It's a right triangle.
Step-by-step explanation:
△ABC with m∠A=30° , m∠B=60° , and m∠C=90°
It's a right triangle.
Is it because the second discount will be determined by the first discounted price, $405, not $450.
Answer:
- a) j+c=310; j-c=40
- b) (j, c) = (175, 135)
- see attached
- Jose earned $175; Camden earned $135
Step-by-step explanation:
Let j and c represent Jose's and Camden's earnings, respectively.
(a) One equation can be written for the total; another for the difference:
j + c = 310 . . . . their total earnings
j - c = 40 . . . . . the difference in their earnings
__
(b) It is convenient to add these two equations to eliminate c:
(j +c) +(j -c) = (310) +(40)
2j = 350
j = 175
Then c can be found as ...
c = j -40 = 175 -40 = 135
The solution is (j, c) = (175, 135).
__
(c) Using x for j, and y for c, we can use Desmos to graph the equations. The result is attached.
__
(d) Jose earned $175 over the summer; Camden earned $135.
