135 140 140 150 155 160 165 170 175
in this pattern you are adding 5 multiple times
To solve this problem you must apply the proccedure shown below:
1. You have the following ratio given in the problem above:
11:1
2. You can rewrite that ratio as below:
11/1=11
3. Then, to find three equivalent ratios, you only need to multiply the numerator (11) and the denominator (11) by the sam number. Therefore, you have:
11x2/1x2=22/2=11
11x3/1x3=33/3=11
11x4/1x4=44/4=11
Therefore, as you can see, the answer is:
22:2
33:3
44:4
Answer: n=7
Step-by-step explanation:
n=number.
2n-5=9
2n=14
n=7
X + y = 61
y - 3x = 5...y = 3x + 5
x + (3x + 5) = 61
4x + 5 = 61
4x = 61 - 5
4x = 56
x = 56/4
x = 14
y - 3x = 5
y - 3(14) = 5
y - 42 = 5
y = 42 + 5
y = 47
ur 2 numbers are 14 and 47
Width of the rectangle is 16 ft and length of the rectangle is 20 ft
<u>Step-by-step explanation:</u>
Step 1:
Given area of the rectangle = 320 ft². Let the width of the rectangle be x, then the length = x + 4. Use the formula for area of a rectangle = (length × width)
320 = x(x + 4)
320 = x² + 4x
x² + 4x - 320 = 0
x = (-b ±√b² - 4ac)/2a = (-4 ±√16 - 4×1×-320)/2
= (-4±√1296)/2 = (-4 ± 36)/2
= 32/2, -40/2 = 16, -20 (neglecting the negative value)
∴ Width of the rectangle = 16 ft
∴ Length of the rectangle = 16 + 4 = 20ft
