30+1.95x=7.95x
so, 6x=30
x=5
Answer:
q= -4
Step-by-step explanation:

Collect like terms and simplify

Divide both sides of the equation by 2

Simplify

Answer:(1, -3).
Step-by-step explanation:
If y=2x-5 is equation (1) and 4x-y=7 is equation (2), then substitute equation (1) in equation (2):
4x - (2x - 5) = 7
4x - 2x + 5 = 7
2x = 7-5
2x = 2
x = 1
Now substitute the value of x in equation (1) to find the value of y:
y = 2 (1) - 5
y = 2 - 5
y = -3
Answer:
25 x D = Y
Step-by-step explanation:
Example: Say he reads for three days a week.
25 x 3 = 75
or 6 days
25 x 6 = 150
or 4
25 x 4 = 100
Answer:
-8
Step-by-step explanation:
-8 * (-2) - 4 * (6) =
16 - 24
0
f(1) = -2
g(4) = 6
