We have x + y = 140 degrees and x = 5y - 13 ;
Then, 5y - 13 + y = 140;
6y - 13 = 140;
6y = 153;
y = 153 ÷ 6;
y = 25.5 degrees;
x = 140 - 25.5;
x = 114.5 degrees;

I dont either tbh
Answer:
a) 4/5 b) -3/4
Step-by-step explanation:
lines that are parallel have the same gradient. So the gradient is 4/5
Lines that are perpendicular have "opposite reciprocal" gradient: flip the sign, then flip the numerator and denominator (top/bottom). So the gradient is -3/4
one inch is 500 miles
therefore, every inch on the map is 500 miles.
8 inches would be 8*500
8*500=4000.
4000 miles is your answer.
Hope i helped!
Ps. brainliest would really help
Answer:
148cm^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is 2(hl)+2(hw)+2(wl).
we just plug in the values.
2(6 x 5) + 2(6 x 4) + 2(4 x 5)
= 2(30) + 2(24) + 2(20) then simplify
= 60 + 48 + 40
= 148
