Answer:
Step-by-step explanation:
1.
Shirts cost $20 each and ties cost $12 each.
<u>Expression for the cost:</u>
Correct choice is B
2.
<u>An expression that represents 40% of a number is:</u>
Correct choice is B. False
3.
t = -2, x = 3 and z = 5
- 4z + 3x − t =
- 4*5 + 3*3 - (-2) =
- 20 + 9 + 2 =
- 31
Correct choice is C. 31
Price is reduced by 45%. Which means that the new price is 55% of the original.
Therefore, (55/100)*17 = $9.35 =new price
I think you have the right answer already
Answer:
€98.
Step-by-step explanation:
A 30% deposit is 0.30 * 840
= €252.
So there is 840 - 252
= €588 left to pay.
The amount of each monthly instalment
= 588 / 6
= €98.
Answer:
y = -x + 4
Step-by-step explanation:
(-1,5)...x1 = -1 and y1 = 5
(1,3)....x2 = 1 and y2 = 3
slope(m) = (y2 - y1) / (x2 - x1) = (3 - 5) / (1 - (-1) = -2 / (1 + 1) = -2/2 = -1
y = mx + b
slope(m) = -1
u can use either of ur points...I will use (1,3)...x = 1 and y = 3
now we sub and find b, the y int
3 = -1(1) + b
3 = -1 + b
3 + 1 = b
4 = b
ur equation is : y = -x + 4 <===
