Answer:
x = 35
Step-by-step explanation:
Solve for x:
5 (x + 20) = 7 x + 30
Expand out terms of the left hand side:
5 x + 100 = 7 x + 30
Subtract 7 x from both sides:
(5 x - 7 x) + 100 = (7 x - 7 x) + 30
5 x - 7 x = -2 x:
-2 x + 100 = (7 x - 7 x) + 30
7 x - 7 x = 0:
100 - 2 x = 30
Subtract 100 from both sides:
(100 - 100) - 2 x = 30 - 100
100 - 100 = 0:
-2 x = 30 - 100
30 - 100 = -70:
-2 x = -70
Divide both sides of -2 x = -70 by -2:
(-2 x)/(-2) = (-70)/(-2)
(-2)/(-2) = 1:
x = (-70)/(-2)
The gcd of -70 and -2 is -2, so (-70)/(-2) = (-2×35)/(-2×1) = (-2)/(-2)×35 = 35:
Answer: x = 35
Y = mx + b slope(m) = -2/3 y-intercept(b) = -5
just simply put where these belong to find your equation.
y = -2/3x - 5
hope this helps, God bless!
Answer:
20112.25
Step-by-step explanation:
4x(5.3)x 20
20.3 x 20= 40.3
40.3 x 20.8= 838.24
838.24 x 24= 20112.25
Answer:
The factorization is given below:
Step-by-step explanation:
The factorization is given below:
a.
(x - 2) (x)
b. 
6(x^2 + 12)
6x (x + 2)
c. 
3(x^2 - 3x)
3(x - 3) (x)
d. 
4x^2 (1 + 7x)
You would have a 26% chance. If you cross multiply using 15/100 and 40/x. 100 times 40 then divide by 15.
