Answer:
Step-by-step explanation:
a. To solve for "y" you want to isolate the variable. What this means is you want to keep "y" on its own. To do this first we will subtract 2x from the equation making 4y = 36 - 2x. Next, we will get rid of 4 to do this divide 4 from both sides. y = (36 - 2x)/4
*I have to go in a bit so sry for no explenation*
b. h = 2a/b
c. x = 1/4y + -3/4
A = price of the desktop
b = price of the laptop
now, we know the laptop was more expensive than the desktop by 250 bucks, thus
b = a + 250.
for "a", he paid 8.5% in interest, for "b", he paid 5% in interest.
how much is 8.5% of a? well (8.5/100) * a, or
0.085a.
how much is 5% of b? well, (5/100) * b, or
0.05b.
now, we know the total charges for financing were $296, that means the interest paid in total was 296, thus whatever "a" or "b" are, we know that 0.085a + 0.05b = 296.

how much did the laptop cost? well, b = a + 250.
Answer:
14.5a + 9.5s = 5,860
a + s = 500

Answer:
can you give me some hint.
To find the answer to this question you would just add 10 to 70 and multiply by 4 and your answer would be 320
