Answer:

For the first image: -0.4/9

Second Image = 1.53/0.45

Step-by-step explanation:

a + b = 1.6 - 2 = -0.4 (The symbols just make it stay negative)

2 - c = 2 - (-7) = 2 + 7 = 9

--------

2a - 1/3 = 2(-3/5) - 1/3 = -1.2 -1/3 = -1.5333

b/15 = -6.75/15 = -0.45

(The two negatives make it positive)

Hope this helps

E is 3 more than d.<br> f is 5 less than d.<br> Write an expression for e in terms of d

Nataly_w [17]

Answer:

Part A:

We are given that E is 3 more than D. This means that to get the value of E, we will simply add 3 to the value of D

Therefore:

E = D + 3

Part B:

We are given that F is 5 less than D. This means that to get the value of F, we will simply subtract 5 from the value of D

Therefore:

F = D - 5

Part C:

To get the value of E-F, we will simply subtract the equation we obtained from part B from the equation we obtained from part A

Therefore:

E - F = (D+3) - (D-5)

E - F = D + 3 - D + 5

E - F = 8

Hope this helps :)

You have $160 and save $7 per week. your friend has $210 and saves $5 per week. afther how many weeks will each of you have save

Naddik [55]

Let the number of weeks needed be x
160 + 7x = 210 + 5x
7x - 5x = 210 - 160
2x = 50
x = 25

Ans: After 25 weeks.
