Answer:
Soda costs $1.15 and taco costs $0.95.
Step-by-step explanation:
x + y = 2.1
2x + 3y = 5.15
Multiply the first equation by -2 to eliminate x
-2x - 2y = -4.2
2x + 3y = 5.15
Add
y = 0.95
Find x with the original first equation
x + y = 2.1
x + 0.95 = 2.1
x = 2.1 - 0.95
x = 1.15
hope it helps :)
Answer:
Step-by-step explanation:
(a,9).......we dont know " a " (or x) but we do know y...it is 9
so sub in 9 for y and solve for x
y = 2x + 1
9 = 2x + 1
9 - 1 = 2x
8 = 2x
8/2 = x
4 = x <======= ur answer is D
Answer:
x = 8^3
Step-by-step explanation:
To rewrite an equation with logs in exponential form, you need to know
logb(a) = m is equivalent to a= b^m
So given log8 (x) = 3 is equivalent to x = 8^3
