Jack wants to model a situation where the perimeter of the rectangle below is 6 ft plus or minus 1.5 ft.
Answer:
Step-by-step explanation:
The perimeter of the rectangle is given as:
The perimeter of a rectangle is:
So, we have:
Substitute values for length and width
Split
or
or
Divide both sides by 2
or
Solve for x
or
or
Both values of x are negative.
This means that; the absolute value model cannot work, because a rectangle cannot have a negative dimension.
Hence, option (c) is correct.

The difference between two positive numbers is 40 and the ratio of these integers is 1:3.Find the integers.
Answer:
the two integers are 20 and 60
Step-by-step explanation:
Let x and y be two positive numbers ,where x < y.
• The difference between the two positive numbers x and y is 40.
Means
y - x = 40
• the ratio of these integers is 1:3
Means
y = 3x
We obtain these two equations:
y - x = 40
y = 3x
Solving the system of equations by substitution :
y - x = 40
y = 3x
⇔
3x - x = 40
y = 3x
⇔
2x = 40
y = 3x
⇔
x = 20
y = 3 × 20 = 60

Answer: -342.7074
Step-by-step explanation: first multiply 7(-2.655), which is -18.585. since only one of the numbers is negative, the product will also be negative. multiply -18.585 by 18.44. this is equivalent to -342.7074.

Answer:
I believe its C, I could be wrong tho
Please hurry will give braliny
Answer: D
Step-by-step explanation:
Follow the PEMDAS rule.
It’s not A, because when you solve 2^2 and sq rt of 4, the square exponent and the square root cancels out, so it’s simply 2 x 4. Then you follow by doing division and multiplication, 45/5 is 9 and 2 x 4 is 8, so 9+8=17.
It’s not B, because first solve the numbers in the parentheses. 2^2 is 4, 5+4 is 9. Then solve the square root of 4 which is 2, and you get 45/9x2, which is 10.
It’s not C because 2^2 is 4 and sq rt of 4 is 2, and 4-2 is 2. Then divide 45 by 5 to get 9, and 9+2 is 11.
The correct answer is D, because when you solve 2^2 which gives you 4 and add that to 5, you get 9. The sq rt of 4 is 2, so you get 45/9-2, which is 3.
Hope this helps!

Q6. -5/2
Q7. -7/24
Q8. 127/24
Q9. 151/12
Step-by-step explanation:
Q6. (−3/4)+(−7/4) = -3-7/4 = -10/4 = -5/2
Q7. 3/8 - 2/3 = 3*3/8*3 - 2*8/3*8 = 9/24 - 16/24 = 9-16/24 = -7/24
Q8. 18+2/3 - 8+3/8 = 20/3 - 11/8 = 20*8/3*8 - 11*3/8*3 = 160-33/24 = 127/24
Q9. 12+1/4 + 27+1/3 = 13/4 + 28/3 = 13*3/12 + 28*4/12 = 39 + 112/12 = 151/12
