Answer:
-1/2
Step-by-step explanation:
The factor outside parentheses multiplies each term inside.
5/2(-8/5 +7/5)
= (5/2)(-8/5) +(5/2)(7/5)
= -8/2 +7/2 = -1/2
Answer:
70
Step-by-step explanation:
The sum of the angles of a triangle should always add up to 180 degrees.
In this problem, they have given us 2 angle measures of the triangle - 40 degrees and 70 degrees. To figure out the third angle, we simply need to figure out how many more degrees we need for reaching the 180 degrees.
I'm just going to do some simple math:
40 + 70 = 110 (sum of the 2 angles)
180 - 110 = 70 (subtracting 180 by the sum of the 2 angles)
Initial dep for A = $200
for A, B, C :
initial dep + 6 (monthly rent) = $5150
For A:
$200 + 6(monthly rent A) = $5150
monthly rent A = (5150 - 200) / 6 = $825
For B:
monthly rent B = monthly rent A - $25 = $800
initial dep B + 6(800) = 5150
initial dep B = 5150 - 4800 = $350
For C:
initial dep C = initial dep B + $150 = $500
$500 + 6(monthly rent C) = 5150
monthly rent C = (5150 - 500) / 6 = $775
C. x+y+72=180
should be correct
