Answer:
-4
Step-by-step explanation:
-4t+15=-1
Subtract 15 on both sides:
-4t=-16
Divide -4 on both sides:
t=-4
Answer:
y -10
x graph
Step-by-step explanation:
TO get the decimal 8 is obviously 8.0 and for 21/40 just divide 40 for both the numerator and denominator. Then add the 8.0 with the answer you get for 40 together to get the final answer.
Y/6 - 5 = 2. First add 5 to both sides. Then multiply both sides by 6. The answer to y is 42. To check plug in 42 for y. 42/6 -5 = 2 ==> 7-5 = 2 ===> 2=2. Therefore it is correct. ANSWER: y=42.
Cost of tablet $315
monthly payments of $25
a. 315 - 25 = $290
b. After each payment, the amount owed decreases. Therefore, the balance decreases.
second part of this: write equation for calculating the amount owed a for any number of payments n $ $25(n-1) =a
I cant draw a graph on here for you, but as n increases, then a decreases
d. as n increases by 1, how does a change? Answer: A decreases by $25 each time n increases by one
e. He will need to make 12.6 payments
