What property do we use when we find equivalent fractions?
Answer:
It's called the cross multiply rule. The rule is shown below: This formula says that if the numerator of one fraction times the denominator of the other fraction equals the denominator of the first fraction times the numerator of the second fraction, then the fractions are equivalent.
Step-by-step explanation:
Mrs. Foust wants to know Aziza’s age. She knows that Aziza is the middle child. Her sister, Capri, is 4 years older than Aziza, and her sister, Portia, is 5 years younger than Aziza. The sum of their ages is 38. Let a represent Aziza’s age. Which statements are true about this scenario? Check all that apply.
Answer:
The expression that represents Capri’s age is a + 4.
The expression that represents Portia’s age is a – 5.
Step-by-step explanation:
The expression that represents Capri's age is a + 4.
The expression that represents Portia's age is a -5.
To write an equation for this scenario, Capri's age needs to be equal to Portia’s age
The equation used to represent this scenario is a + a + 5 + 2 - 4 = 38.
Solving this equation will give Aziza's age.
Aziza'a age = a
Portia age = a - 5
Capri's age = 4 + a
a + a - 5 + 4 + a = 38
Simplify

Can you guys help me with this please it suppose to use the synthetic substitution or the remainder theorem.
9514 1404 393
Answer:
(b) -36
Step-by-step explanation:
Synthetic division is often performed using a table of the kind shown in the attachment. The coefficients of f(x) are placed across the top, and the x-value to be evaluated is placed at the left. The rule for finding table entries is shown. (The first (left-most) number at the bottom is the leading coefficient of the polynomial.)
This table shows the remainder, which is f(-2), is -36.
__
The equation itself can be rewritten in "Horner form" to facilitate evaluation.
f(x) = (((-x +2)x -1)x +4)x +8
In this form, substituting for x and doing the evaluation is easier for mental arithmetic. You will notice that the contents of parentheses at each level match the bottom line of the synthetic division table.
f(-2) = (((-(-2) +2)(-2) -1)(-2) +4)(-2) +8
= (((4)(-2) -1)(-2) +4)(-2) +8
= ((-9)(-2) +4)(-2) +8
= (22)(-2) +8
= -36
f(-2) = -36 . . . . remainder from synthetic substitution
Franco earns $8 per hour at his after-school job. Last week, he received a paycheck of more than $168. If he worked for h hours that week, find all the inequalities that represent this situation.
a.) 8 x h > 168
b.) 8 > 22 x h
c.) 8 x h < 168
d.) h > 21
e.) h < 21
Answer: A and D
Step-by-step explanation:
if he earns $8 an hour and he got $168 and h= the hours then
h=8 x 21 = 168

Help me with this!!! Fake answers will get reported
Answer:
Step-by-step explanation:
there is an obscure rule that looks like this
DB/AB = AB/CB
AB=40 for this problem
DB = x
CB = 20
then
X/40 = 40/20
X = 40(40/20)
X = 40(2)
X=80
I find that hard to believe too, :D
but the rule says that's right
Brad read that you should drink at least 2 quarts of water a day. Yesterday he drank 3 cups in the morning, 1 quart in the afternoon, and 1 pint in the evening. Did Brad drink at least 2 quarts of water? Explain.
Answer:
yes he drank 2.25 quarts
Step-by-step explanation:
convert the cups to quarts
1 cup = 0.25 quarts
3 cups x 0.25 = 0.75 quarts
convert the pints to quarts
1 pint = 0.5 quarts
add all the amount of water drank together
0.75 quarts + 1 quart + 0.5 quarts = 2.25 quarts

You and your friend were working the ticket table at the last school basketball game.
The tickets sold for $5 for adults and $3 for students.
A total of 375 people attended the
game and a total of $1375 was taken in at the ticket table. How many adult tickets were
sold and how many student tickets were sold?
Answer:
Step-by-step explanation:
First
a+s=375
a=375-s
Next
5a+3s=1375, now using a found above makes this equation become
5(375-s)+3s=1375
1875-5s+3s=1375
1875-2s=1375
-2s=-500
s=250, since a=375-s
a=375-250
a=125
So 125 adult and 250 student tickets were sold.

Answer:
4. 300 5. 7 6. 2
Step-by-step explanation:
In order to solve these problems, we need to plug in x for the missing number. So, we would set it up like this:
[tex]\frac{60 mi}{1 hr} =\frac{x}{5 hr}[/tex]
We would then cross multiply in order to find the value of x. Like this:
60 × 5 = 300
1 × x = 1x
300 = 1x
300 = x
So now we know that x is 300.
We would do the exact same thing for the next question. Plug in x, then solve by cross multiplying:
[tex]\frac{8 hr}{2 days} =\frac{28 hr}{x}[/tex]
8 × x = 8x
2 × 28 = 56
8x = 56
÷8 ÷8
x = 7
We now know that x is 7.
Try the last one on your own. Do the exact same thing I did for the first two. I hope you understand a bit better now. Please let me know if you need any more help. Good luck!

A veteran math teacher at a large high school claims that 93% of their students pass the state’s final exam. A random sample of 120 of the teacher’s students was chosen, and 108 passed the state’s final exam. Let p hat = the proportion of the random sample who passed the state’s final exam.
The probability that 90% or fewer of this teacher’s students passed the state’s final exam is 0.096. Does this result provide convincing evidence against the teacher’s claim?
Yes, it is expected that at least 90 of the students will pass the state’s final exam.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
Answer:
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.

Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.
Question:
Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.
Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.
Answer:
[tex]y=x +45[/tex]
[tex]y = 45 + x[/tex]
Step-by-step explanation:
From the complete question, we have:
Jordyn & Teri
[tex]Rolls = 1[/tex]
[tex]Extra = 45\ yd[/tex]
Morgan
[tex]Rolls = 3[/tex]
[tex]Extra= 10\ yd[/tex]
Required
Expression for Jordyn and Morgan
Let the total kite by Jordyn and Teri be represented with y
This is calculated as:
[tex]y = Rolls + Extra\ Yard[/tex]
This gives:
[tex]y = 1\ roll + 45yd[/tex]
1 roll is represented with x.
So:
[tex]y=1x +45[/tex]
[tex]y=x +45[/tex]
This can be rewritten as:
[tex]y = 45 + x[/tex]
