The answer is x=-2 because its the only one thats parallel to the y axis
Answer:
2.23kg
Step-by-step explanation:
If you can get 1 kg for $4.50. You can perform a ratio to find out how much you get for $10.
1/4.50=x/10
.2222222=x/10
multiply the 10 on both sides
x=2.23 kg for $10
Answer:
10 and a half hours
Step-by-step explanation:
1.5x7=10.5
(4,3). The x is 4 and it cant be (4,6) because the graph goes by the multiple of 2.
Q2. The answer is <span>D. 2w + 2 • (3w) ≤112
</span>
The perimeter of a rectangle is: P = 2w + 2l (w - weight, l - length)
<span>
The perimeter is at most 112 centimeters: P </span>≤ 112
<span>The length of a rectangle is three times its width: l = 3w
</span>P ≤ 112
2w + 2l ≤ 112
l = 3w
2w + 2 * (3w) ≤ 112
Q2.2. The answer is <span>D. 8 cm
</span>
The perimeter of a rectangle is: P = 2w + 2l (w - weight, l - length)
<span>The length of a rectangle is five times its width: l = 5w
</span><span>The perimeter is at most 96 centimeters: P </span>≤ 96
P ≤ 96
2w + 2l ≤ 96
l = 5w
2w + 2 * 5w ≤ 96
2w + 10w ≤ 96
12w ≤ 96
w ≤ 96 : 12
w ≤ 8 cm
