Answer:
D. no solution
Step-by-step explanation:
h-z=3(1)
h=3+z(minus z from both side)
put in the second equation
-3h,+3z=6(2)
-3(3+z)+3z=6
-9-3z+3z=6
-9=6( not true)
so the equation doesn't have a solution.
Answer:
i think its 330 so sorry if im wrong
Step-by-step explanation:
Answer:
112.065
Step-by-step explanation:
so divide the triangle in two from x to wy
and you get to triangles
then using the first right angled triangle you can apply tan=opposite/adjacent
to get height as 7.56 then apply 1/2bh to get first area as 58.59
first add all angles and subtract from 180=24
then use tan to get the height as 6.9
then apply 1/2bh to get second area as 53.48
then add the two areas to get total
(after getting first one don't multiply by two)
Answer:
That day Jiao spent $CNY 514.29.
Step-by-step explanation:
Given that Jiao is a Chinese student visiting family in the United States, and she spent $ 79 on dinner for her family one evening, if the exchange rate that day is UDS to CNY = 6.51, to determine approximately how much money did she spend in CNY the following calculation must be performed:
79 x 6.51 = X
514.29 = X
Therefore, that day Jiao spent $ CNY 514.29.
Answer: x = -3
Step-by-step explanation:
i simply divided by -7, in order to get x by itself.
-7/-7x = 21/-7
that cancels out the -7 on the left side, and leaves us with -3 on the right side!
x = -3
