Identify and describe how he made his mistake. Then, solve the problem correctly.
Gerald's work
Answer:
x = 18.7
Step-by-step explanation:
Gerald's answer is almost correct.
He just needs to switch the 14 and the x.
it should be
24/x = 18/14
solve for x by cross multiplication
18x = (24)(14)
18x = 336
x = 18.7
Decrease 18000 by 6%
Answer:

18000-6% of 18000
=18000-6/100*18000
=18000-1080

The Emerald Bot clicks 3 times in ____ sec, and its Unit Rate is 7.5 clicks per second. Find the number of sec.
Answer: The Emerald Bot clicks 3 times in __0.4_ sec
²/₁₅ second per click × 3clicks = ²/₅ sec
Or 0.1333 × 3 = 0.3999 Round to 0.4
Step-by-step explanation: If its unit rate is 7.5 clicks per second, we can find the time, seconds per click by dividing one second by 7.5 clicks
1/7.5 = 0.13333 seconds per click.
Multiply that ²/₁₅ seconds by the 3 clicks to get the time it takes for the 3 clicks.
A line has a slope of 5 and includes the points (1,t) and (3,2). What is the value of t?
Hello!
[tex]\large\boxed{t = -8}[/tex]
We can find the value of t using the slope formula:
[tex]slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Plug in the given slope and coordinates into the appropriate places:
[tex]5 = \frac{2-t}{3-1}[/tex]
Simplify:
[tex]5 = \frac{2-t}{2}[/tex]
Multiply both sides by 2 to begin isolating for t. Simplify and solve for t:
[tex]5 * 2 = 2 - t\\\\10 = 2 - t\\\\8 = -t\\\\t = 8[/tex]
Which sum is equal to
8/12
Answer: 2/3
Step-by-step explanation:
For example, if we multiply the numerator and denominator of 2/3 by 4 we get. 2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3.
Answer:
either 4/6 or 2/3
Step-by-step explanation:
Because 12 can be divide in half which is 6, and 8 divided by 2 is 4, so your fraction is now 4/6. if this answer isn't on the screen then you have to do it again: 4 divide by 2 is 2, and 6 divided by 2 is 3, so your fraction is now 2/3.

Jesse has a collection of nickels and quarters worth $5.00. She has 40 more nickels then quarters. How many coins of each type does she have?
Answer: Jesse has 50 nickels and 10 quarters
Step-by-step explanation:
set up a system of equation
q is quarters and n is nickels
q+40=n is the first equation
.05n+.25q = 5 or 5n+25q=500
solve by substitution
5(q+40)+25q=500
5q+200+25q=500
30q=300
q=10
substitute back into the original equation
10+40=n
50=n

Please help.Find the circumference (to the nearest whole number). Use 3.14 for pi.
A.116 in
B. 88 in
C.44in
D.None of the above
The circumference is approximately 88 inches.
The correct option is B. 88 in.
To find the circumference of a circle, we can use the formula:
C = 2πr,
where C represents the circumference and r represents the radius of the circle.
Given that the radius, r, is 14 inches, we can substitute this value into the formula:
C = 2 x 3.14 x 14.
C ≈ 87.92 inches.
Thus, the circumference is approximately 88 inches.
