the only thing you need to do is separate m:
2/7m= 3/14 + 1/7
2/7m= 5/14
m= (5/14)/(2/7)
m= 5/14 × 7/2
m= 35/28
m= 5/4
Answer:
25
Step-by-step explanation:
5:20
We want to get the second number to 100
100/20 = 5
Multiply each term by 5
5*5 : 20*5
25 : 100
x is 25
The y-intercept is the constant in the equation: 5.

Answer:
y = 20
Step-by-step explanation:
Since AB and AC are congruent then the triangle is isosceles, thus
∠B = ∠C = 25°
To find ∠A subtract the sum of the 2 angles from 180°
∠A = 180° - (25 + 25)° = 180° - 50° = 130°, thus
3y + 70 = 130 ( subtract 70 from both sides )
3y = 60 ( divide both sides by 3 )
y = 20
