Answer:
9
Step-by-step explanation:
The value of the sum is ...
(10A +B) +(10B +A) = 102 +10A
11A +11B = 102 +10A
A +11B = 102 . . . . . . . subtract 10A
Dividing by 11, we have ...
A/11 +B = 9 3/11
This tells us A=3, B=9.

What is the value of the expression when b = 2 and c = –3? Enter your answer in the box.
Answer:
The answer to your question thinking that you're multiplying is -6
Step-by-step explanation:
The value of the expression b²+ c², when b = 2 and c = –3, is 13.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
We have an expression,
b²+ c².
The value of the expression when b = 2 and c = –3,
= (2)²+ (-3)²
= 4 + 9
= 13
Therefore, the value is 13.

If the ordered a pair (6,2) is the solution to the system, what does that mean?
It means that the point (6,2) is on both graphs at the same time. In short, it is the intersection point of the two graphs.
Algebraically, the ordered pair (x,y) = (6,2) makes all of the equations in the system to be true equations. A true equation is one where it simplifies to have the same number on both sides.
A system with at least one solution is considered a consistent system. If there is only one solution, then the system is also considered independent.
3.5 h+4.5)= 57 whats the value for h

have a great day.
✧･ﾟ: *✧･ﾟ:･ﾟ✧*:･ﾟ✧･ﾟ: *✧･ﾟ:･ﾟ✧*:･ﾟ✧
Step-by-step explanation:
Answer:
The answer is h=15
Step-by-step explanation:
3.5 h+4.5)= 57
Let's solve your equation step-by-step.
3.5h+4.5=57
Step 1: Subtract 4.5 from both sides.
3.5h+4.5−4.5=57−4.5
3.5h=52.5
Step 2: Divide both sides by 3.5.
3.5h/3.5=52.5/3.5
h=15
Answer: h=15

Answer:
6 1/2
Step-by-step explanation:
To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2. Sorry if it's confusing hope it helps :)

Each day a machine makes 500000 staples and puts them into boxes.
The machine needs 165 staples to fill a box.
How many boxes will be filled with the 500,000 staples?
Answer:3031 boxes will be filled with staples
Step-by-step explanation:
Given that the machine makes 500000 in a day
So total staples = 500000
Staples in a box = 165
In order to find how many boxes the machine will make, the total number of staples has to be divided by the number of staples in a box.
So,
[tex]number\ of\ boxes = \frac{Total\ staples}{Staples\ in\ a\ box}\\= \frac{500000}{165}\\= 3030.30[/tex]
As no staples can be left out of box, we will round off the number to next number.
So,
3031 boxes will be filled with staples
Answer:
3031 boxes

The fabric for a dress costs $180 for 9 yards.
What is the cost per yard?
Answer:
$20
Step-by-step explanation:
because it wants the cost per yard so you need to do the amount ($180) and divide by the yards (9) so you do 180 ÷ 9 = 20
So there for, you get $20

A ride-sharing company claims that the cost of rides follows a Normal distribution with a mean of $10.52. After
paying for a ride from this company, a rider reports that his price is in the 85th percentile of all other riders' prices. If
this rider paid $15.93, what is the approximate standard deviation of this company's ride-sharing cost?
Answer:
$5.20
Step-by-step explanation:
According to the Z-Score chart, the 85th percentile has a z-score of 1.04 and if you put that in the z-score equation (15.93-10.52)/x=1.04. Solve for x and you get $5.20.

Operations With Fractions
Simplify the following operations:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)[/tex]
Convert the mixed fractions to improper fractions:
[tex]\displaystyle 5\frac{1}{4}= 5+\frac{1}{4}=\frac{21}{4}[/tex]
[tex]\displaystyle 7\frac{1}{2}=7+\frac{1}{2}=\frac{15}{2}[/tex]
Substituting:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}-\left(-\frac{15}{2}\right)[/tex]
Simplifying:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}+\frac{15}{2}[/tex]
Amplifying the second fraction by 2:
[tex]\displaystyle -5\frac{1}{4}-\left(-7\frac{1}{2}\right)=-\frac{21}{4}+\frac{30}{4}[/tex]

Choose the best answer. What is the value of the expression x + (-y) when x = 1.2
and y = -10.72
-9.5
11.9
-11.9
9,5
Answer:
[tex]-9.5[/tex] is the best answer.
Step-by-step explanation:
Given the expression
[tex]x + (-y)[/tex]
putting x=1.2 and y=-10.72 in the expression
[tex]x\:+\:\left(-y\right)=1.2\:+\:\left(-10.72\right)[/tex]
[tex]=-9.52[/tex]
Therefore, -9.5 is the best answer.
