Answer:
-7/24 = r
Step-by-step explanation:
3/8 = r + 2/3
Subtract 2/3 from each side
3/8-2/3 = r + 2/3-2/3
3/8 - 2/3 = r
Get a common denominator or 24
3/8 *3/3 - 2/3 *8/8 =r
9/24 - 16/24 =r
-7/24 = r
WELP WILL MARK BRAINLEST 4. Part A: Jerry claimed that the expression -8 + d is negative. Determine whether Jerry's claim is always true, sometimes true, or never true. Provide evidence to support your conclusion. (10 points)
Answer: His claim is SOMETIMES true.
Let's just take an example, d=2.
-8 + 2 equals -6, so negative. BUT, let's say d=9.
-8 + 9 equals 1, 1 is positive.
Jerry's claim is sometimes true.
A thunderstorm cloud holds about 6,200,000,000 raindrops. Which of the following shows this number in scientific notation? Answers- F- 0.62*10 to the 10th power G- 6.2*10 to the 9th power H- 6.2*10 to the 8th power J-62.0*10 to the 8th power
Answer:
the answer is G
which is 6.2*10 to the 9th power.
Step-by-step explanation:
In scientific notation you must leave one digit to the place value of ones
so that one digit is 6
So ue come up with 6.2 when ue eliminate all other zeros and end the decimal point between 6 and 2 and that way you have 6.2*10 to the 9th power
Answer:
G, 6.2*10 to the 9th power.

The width of the fountain in Luke's drawing from the example is 2 cm. What is the width of the fountain in Isabella's scale drawing?
Answer:
2.5cm
Step-by-step explanation:
If Luke's scale for his drawing is 5m to 2cm, then it means that every 2cm on Luke's scale drawing represents 5m in real life. So since the width of the fountain is 2cm, the actual fountain width must be 5m. As established in the example, Isabella's scale factor from drawing to real life is 6/3=2, which means any measurement in cm on her drawing can simply be multiplied by 2 to obtain the real life measurement in m. So, to convert back the other way, from real-life to drawing, we just need to divide the value by 2 instead of multiply. So, if the real life value is 5m, then the width on her scale drawing should be 5/2 = 2.5cm.
Hope this helped!
Using proportions, it is found that:
The width of the fountain in Isabella's scale drawing is of 1.6 cm.
-----------------------------------
This question is solved by proportions, using a rule of three.
Isabella's scale is of 6m to 3cm, that is, 2m to 1cm.Luke' scale is of 5 m to 2 cm, that is, 2.5m to 1 cm.From this, it can be taken that a drawing of 250cm in Luke's scale is of 200 cm in Isabella's scale.What is the width of Isabella's drawing, considering that Luke's width is 2 cm?200 cm - 250 cm
x cm - 2 cm
Applying cross multiplication:
[tex]250x = 400[/tex]
[tex]x = \frac{400}{250}[/tex]
[tex]x = 1.6[/tex]
The width of the fountain in Isabella's scale drawing is of 1.6 cm.

Answer:
(5 * n) + 7
Step-by-step explanation:
Since we do not know the value of n, we can't write an equation for this. You could also write it as 5n + 6.7 if you'd like. Since letters and numbers don't mix, we can't add 6.7 to 5n. I rounded 6.7 to 7 in my answer. Hope this helped.

A hot air balloon rose from ground level to 1000 feet in order to pass over a mountain. The balloon then descended
800 feet to a cruising height.
Which point is a representation of cruising height in feet?
Point A
Point B
Point C
Point D
200ft.
Step-by-step explanation:
It's 200ft because you just do 1000 - 800 = 200ft
Point C represent the cruising height.
What is number line?when we represent the numbers on a line the numbers can be positive negative or any type are done on number line zero is the center of the number line.
Given that air balloon height is 1000 feet from ground
and descended to 800 feet
present height of air balloon is 1000 - 800 = 200 feet
Hence according to no. line in figure 200 feet lie in point C
