Answer:
The answer is A. "x = -3"
Answer:
x must be a negative i mean it has to how tfk do you get zero at an answer what kn the world
The linear equation:
y = k x + b
We will use first two values and solve the system of equations:
11 = k * 7 + b / *(-1)
13 = k * 8 + b
---------------------
-11 = - k * 7 - b
13 = k * 8 + b
----------------------
2 = k
13 = 16 + b
b = 13 - 16 = -3
y = 2 x - 3 ( y varies directly with x )
1. 3in =5ft, 6in=10ft, 9in=15ft, 12in=20ft, 18in=30ft, 21in=35ft (multiples of 3 for the top row, the bottom row is multiples of 5. when the second column appears 3x2 is 6 and 5x2 is 10, and keep going. whatever number you multiply 3 by is the same number you multiply 5 by.)
a) 30ft
b) Actual is 2.5ft and would be the bottom row. You would divide 5 by 2. Do the same for 3 and it is 1.5in.
2. Scale 2in = 4ft.
The scale dimensions of a room is 14x7
2×x=14 x=7 7×2in=14in. The actual wall would be 7×4=28ft
The scale drawing is 7in. 3.5×2=7in Then 3.5×4=14ft
Final dimensions, 28ft x 14 ft.
3. 2cm = 5m Scale
10cm = 25m. 10cm=2×5. 5m×5=25m
6cm = 15m, 6cm=2×3. 5m×3=15m
Answer:
a) How many full packages will be used to ship the jeans?
41 packages
b) How many jeans are left over?
24 Jeans
Step-by-step explanation:
We are told that a manufacturer: made 1500 Jeans and is shipping them in packages of 36.
Hence, the number of packages of 36 he can send out to stores is calculated as:
1500÷ 36
= 41.666666667
In whole number packages = 41 packages
Hence, 41 full packages would be used to ship the jeans.
The number of Jeans left behind is
1500 - (41 × 36)
= 1500 - 1476
= 24 Jeans
