Answer:
x=-1, y=6. (-1, 6).
Step-by-step explanation:
x+y=5
x-y=-7
---------
2x=-2
x=-2/2
x=-1
-1+y=5
y=5-(-1)=5+1=6
Answer:
infinity :)
Step-by-step explanation:
A. I believe, b is a full circle and c is a right angle
I’m not 100% but wouldn’t it be t = d/r
C = d + 3
In this equation, the variable c represent's Carter's score, and the variable d represents Denise's score. Because Denise scored 3 fewer points than Carter, that means that Carter scored 3 more points than Denise. Therefore, d, or Denise's score, is equal to c, or Carter's score, if you add 3. Now, let's substitute in Denise's score of 18.
c = 18 + 3 Substitute
c = 21 Add
Carter's score is 21. If we wanted to check that, we could simply reverse the equation.
d = c - 3 Because Denise scored three fewer points than Carter, his score equals Carter's score minus 3.
d = 21 - 3 Now, let's substitute in the answer we got for Carter's score.
d = 18 Yep! The question says that Denise scored 18 points, so the answer we got is correct.
