Step-by-step explanation:
42:24
divide both sides by 6
7:4
Answer:
Find the GCD (or HCF) of numerator and denominator. GCD of 42 and 24 is 6.
42 ÷ 624 ÷ 6.
Reduced fraction: 74. Therefore, 42/24 simplified to lowest terms is 7/4.

Explanation:
Think of z as having 1 zebra
2z means we have 2 zebras
If we started with 2z, and subtracted off 2z, then we're left with 0 zebras. We write this as 0z or just 0 since 0 times anything is 0.
---------
As another example:
Let's say we wanted to simplify 5z - 2z
Well that's the same as saying "5 zebras take away 2 zebras". We'd be left with 3 zebras because 5-2 = 3
Since 5-2 = 3, this leads to 5z-2z = 3z. The difference is that I tacked 'z's onto each number.

At a hockey game, a vendor sold a combined total of 148 sodas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.
If the number of sodas sold was three times the number of hot dogs sold then the number of sodas sold is 78 and the number of hot dogs sold is 26.
What is equation?Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.
here, we have,
The total number of hot dogs and sodas sold is 104 and the number of sodas sold was 3 times the number of hot dogs sold.
We have to form an equation first.
let the number of hot dogs sold be x.
Number of sodas will be 3x.
According to question :
x+3x=104
4x=104
x=26
Put the value of x in 3x to get the number of sodas sold.
=3x
=3*26
=78
Hence If the number of sodas sold was three times the number of hot dogs sold then the number of sodas sold is 78 and the number of hot dogs sold is 26.

(tan^(2)x)/(secx)=secx-cosx how do i verify the identity
Answer:
sec x − cos x = sin x tan x? First convert all terms into sinx and cosx. Second apply fraction sum rules to the LHS. and replace secx with 1 cosx. The LHS, secx − cosx becomes 1 cosx − cosx. The RHS, sinxtanx becomes sinx sinx cosx or sin2x cosx.

Consider a class with 30 students. Compute the probability that at least two of them have their birthdays on the same day. (For simplicity, ignore the leap year.) (b) How many students should be in class in order to have this probability above 0.5
Answer:
0.7063
Step-by-step explanation:
Given that:
Number of students = 30
Number of days in a year = 365
P(atleast 2 people share same birthday) = 1 - p(none share same Birthday)
p(none share same Birthday) =
(365! / (365 - 30)!) * 1/365^30
(365! / 335!) * 1/365^30
365! ÷ (335! * 365^30)
= 0.2936837
P(atleast 2 people share same birthday) :
1 - 0.2936837
= 0.7063163
= 0.7063 * 100%
= 70.63%

A phone company has two long distance calling plans. The first plan is $25 per month plus $0.01 per minute of long distance calling after the first 100 minutes. The second plan is $10 per month plus $0.05 per minute of long distance calling.
How many minute of long distance calls will it take for the plans to cost the same amount?
Answer:
286 minutes
Step-by-step explanation:
can you give brainlest or good review
Answer:
Hello!
Let's call X to the number of minutes of long-distance calls you plan to make.
The cost of plan A is given by 25%2B0.05X
The cost of plan B is given by 5%2B0.12X
Plan B is advantageous when its cost is lower than plan A's. Therefore, we set the inequality
5%2B0.12X+%3C+25%2B0.05X
And then solve for X. This will give us the range of minutes for which B is more convenient.
Subtract 5 from both sides of the inequality to get:
0.12X+%3C+20%2B0.05X
Now subtract 0.05X:
0.12X+-+0.05X+%3C+20
0.07X%3C20
Finally, divide by 0.07 to get:
X+%3C+20%2F0.07
X++%3C+285.71
So plan B is advantageous if you plan to use less than 286 minutes of long distance calls.
I hope this helps!

Martha earns $15 per hour for babysitting. The parents always giver her a $5 tip.
What is the slope of this situation?
Enter the correct answer in the box.
? Dollars per hour
Answer:
$3.25 multiplied by the hour
Step-by-step explanation:
The slope of the situation if, Martha earns $15 per hour for babysitting, The parents always give her a $5 tip is $15 per hour.
What is the slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
Given:
Martha earns $15 per hour for babysitting,
The parents always give her a $5 tip,
The equation for the total money earned by Martha can be written as shown below,
The total money earned = Money per hour for babysitting × number of hours + tip
Assume the total money earned is y, the number of hours is x,
y = 15x + 5
As you can see, the above equation is in slope intercept form,
Slope = $15 per hour

Solve 3(x + 1) = −2(x − 1) − 4
-1
1
-3
5
Answer:
x = -1
Step-by-step explanation:
3(x + 1) = -2(x - 1 ) - 4
use the distributive property to get rid of the parentheses. on -2 and -1 they cancel each other out so it becomes + 2. now you have:
3x + 3 = -2x + 2 - 4 (+2 and -4 are like terms so they become -2. so technically its 3x + 3 = -2x -2)
get +3 on the other side by subtracting it from itself and then subtracting it from -2 so it becomes -5.
3x = -2x - 5
get -2x on the other side by adding 2x to itself then adding 2x to 3x so it becomes 5x
5x = -5
divide 5 from -5 and you get x = -1

Step-by-step explanation:
If R is the midpoint of PS with PR=6x+16 and RS=-26 then find PS
Answer:
PS = 116
Step-by-step explanation:
Given:
PR = 6x + 16
RS = 12x - 26
Required:
Find PS
Solution:
Since R is the midpoint of PS, therefore,
PR = RS
6x + 16 = 12x - 26
Collect like terms
6x - 12x = -16 - 26
-6x = -42
Divide both sides by -6
x = -42/-6
x = 7
✔️PS = PR + RS (segment addition postulate)
PS = 6x + 16 + 12x - 26
Plug in the value of x
PS = 6(7) + 16 + 12(7) - 26
PS = 42 + 16 + 84 - 26
PS = 116
Solve for x.
