IF HJ = 7x-27, find the value of x
Answer:
x= (1/7)hj + (27/7)
Step-by-step explanation:
1) Flip the equation:
7x-27=hj
2) add 27 to both sides
7x = hj +27
3) divide both sides by 7
x = 1/7hj + (27/7)

Please help me I am stuck :(
Answer:
Step-by-step explanation:
This is a definite maybe kind of question.
Start with the 280. It has a range of 280 +/- 10 mL. That means that each serving is between 270 and 290. If she serves exactly 280 every time she will need 22 * 280 = 6160 mL or 6160/1000 = 6.16 L which gives her a margin of 0.340 L or 340 mL
Consider 270 mL
270 mL * 22 = 5940 mL or 5.94 L She has a little over 1/2 L left over. She has enough soup for 22 people.
Finally think about 290 per serving
290 * 22 = 6380. This should work as well providing she has more than 6.38 Liters which is not a slam dunk. With a leeway of 0.5 L and she only makes 6 Liters, she does not have enough.
So maybe. (Since you can explain this question, you can, I should think, use 0.5 Liters as a leeway).
There is one condition I have not considered and that is what happens if you have 7 Liters of soup? Then the leeway in the serving size does not matter.

A doctor has found that, over the years, 95% of the babies he has delivered weighed |x-7.9|<1.5 pounds. What range of weights corresponds to this inequality?
Work Shown:
| x-7.9 | < 1.5
-1.5 < x-7.9 < 1.5
-1.5+7.9 < x-7.9+7.9 < 1.5+7.9
6.4 < x < 9.4
x is between 6.4 and 9.4, excluding both endpoints
The doctor observed over the years that 95% of the babies weighs greater than 6.4 pounds and less than 9.4 pounds.
What is inequality ?Inequality is a mathematical tool for comparing non-equal values.
According to the given question a doctor has found that, over the years, 95% of the babies he has delivered weighed |x-7.9|<1.5 pounds we have to find the range of weights corresponding to this inequality.
|x-7.9|<1.5
∴ x - 7.9 < 1.5
x < 1.5 + 7.9
x < 9.4.
OR
- ( x - 7.9 ) < 1.5
- x + 7.9 < 1.5
- x < 1.5 - 7.9
- x < - 6.4 ( think of moving the terms to other side to make it positive
x > 6.4. and inequality also changes )

The perimeter of a rectangle is 60 meters. Its length is 10 meters. What is its width?
Answer:
[tex]\boxed {\tt 20 \ meters}[/tex]
Step-by-step explanation:
The perimeter of a rectangle can be found using the following formula.
[tex]p= 2l+2w[/tex]
We know the perimeter is 60 meters and the length is 10 meters.
[tex]p=60 \ m[/tex]
[tex]l= 10 \ m[/tex]
Substitute the values into the formula.
[tex]60 \ m = 2(10 \ m) + 2w[/tex]
Multiply 2 and 10.
[tex]60 \ m = 20 \ m +2w[/tex]
Subtract 20 from both sides of the equation.
[tex]60 \ m - 20 \ m = 20 \ m - 20 \ m +2w[/tex]
[tex]60 \ m - 20 \ m =2w[/tex]
[tex]40 \ m = 2w[/tex]
Divide both sides of the equation by 2.
[tex]\frac{40 \ m}{2} =\frac{2w}{2}[/tex]
[tex]\frac{40 \ m}{2} =w[/tex]
[tex]20 \ m =w[/tex]
The width of the rectangle is 20 meters.

b) Each stage adds a square above and a square to the right. The pattern never decreases. This trend is shown by figures 1, 2, and 3.
c) Figure 0 would be a single square. Simply follow the pattern in reverse. As the figure number decreases, squares are removed from the right and the top rather than added.
Write the equation of the line that passes through the given points.
(0,−1) and (−3,−9)
Let's write the line in slope-intercept form.
y = mx + b
m = slope
b = y-intercept.
Let's use the two points to calculate our slope.
Slope = (-9 -(-1)) / -3 = -8 / -3 = 8 / 3
Our line so far: y = 8/3x + b
Let's plug one of our points into the equation to find b.
-1 = 8/3(0) + b
-1 = b
Our line is: y = 8/3x - 1
