Answer:
1. 9/10
2. 15/16
4. 3/5
5. 3/5
Step-by-step explanation:
1. 7/10 + 2/10 = 9/10
2. 13/16 + 2/16 = 15/16
4. 7/15 + 2/15 = 9/15 = 3/5
5. 9/20 + 3/20 = 12/20 = 3/5
Answer:
y= 84
Step-by-step explanation:
y = kx
where k is the constant
k = y/x = 91/13 = 7
the value of Y when x= 12
y = kx =7(12)
y =84
The formula for a circumference of a circle is 2πr
2 × π × 25 = 157
so your answer is A 157in.

Area=1/2 times bas time height
given that area=10
height=5
find base
10=1/2 times base times 5
times 2 both siddes
20=base times 5
divide oth sides by 5
4=base
the base is 4m
4x-30=2x+50
+30 +30
4x=2x+80
-2x -2x
2x=80
/2 /2
X=40
4(40)-30=130°
2(40)+50=130°
180-130=50°
Angle 7=50°
