Answer:
10/12 also 5/6
Step-by-step explanation:
Answer:
10/12 or the simplified version 5/6
Step-by-step explanation:
you have to multiply 2/3 by the reciprocal of 4/5 which is 5/4
so you write down 2/3 times 5/4 (just multiply across so it's 2x5 over 3x4)
2x5=10 and 3x4=12
10 is the numerator and 12 is the denominator
simplify if the problem calls for it by dividing the top and bottom numbers by 2

Problem: Four students tried to write 12x + 3y=9 in equivalent y= mx + b form.
Question: Did each student get an equation that is equivalent to the original Ax + By=C form?
If so, explain the reasoning for each step. If not, tell what errors the students made.
Find the product of each expression using properties of complex numbers.
1. (x + 3i)(x − 3i)
2. (x − 4i)(x + 4i)
3. (x + 8i)(x − 8i)
Answer:
[tex](x+3\mathbf{i})(x-3\mathbf{i})=x^2+9[/tex]
[tex](x-4\mathbf{i})(x+4\mathbf{i})=x^2+16[/tex]
[tex](x+8\mathbf{i})(x-8\mathbf{i})=x^2+64[/tex]
Step-by-step explanation:
Complex Numbers
The complex numbers are known by having an 'imaginary' part along with the real part. They can be expressed like a + bi, where
[tex]\mathbf{i}=\sqrt{-1}[/tex]
Or, equivalently:
[tex]\mathbf{i}^2=-1[/tex]
Let's find the result of the following products. On each one of them, there is a sum of a binomial multiplied by the subtraction of a binomial with the very same terms. It leads to a well-known polynomial identity:
[tex](a+b)(a-b)=a^2-b^2[/tex]
1. [tex](x+3\mathbf{i})(x-3\mathbf{i})[/tex]
Applying the above-mentioned identity:
[tex](x+3\mathbf{i})(x-3\mathbf{i})=(x^2-(3\mathbf{i})^2)[/tex]
[tex]=x^2-9\mathbf{i}^2[/tex]
Since [tex]\mathbf{i}^2=-1[/tex]
[tex](x+3\mathbf{i})(x-3\mathbf{i})=x^2-9(-1)[/tex]
[tex]=x^2+9[/tex]
2. [tex](x-4\mathbf{i})(x+4\mathbf{i})[/tex]
Proceed in the same way as before:
[tex](x-4\mathbf{i})(x+4\mathbf{i})=(x^2-16\mathbf{i}^2)[/tex]
[tex]=(x^2-16(-1))[/tex]
[tex]=x^2+16[/tex]
3. [tex](x+8\mathbf{i})(x-8\mathbf{i})[/tex]
[tex](x+8\mathbf{i})(x-8\mathbf{i})=(x^2-64\mathbf{i}^2)[/tex]
[tex]=(x^2-64(-1))[/tex]
[tex]=x^2+64[/tex]

Step-by-step explanation:
7 -14m = 2m - 5 multi step variables on both sides
7 - 14m = 2m - 5
+14m +14m (add 14 on both sides)
_____________
7 = 16m - 5
+5 + 5 (add 5 on both sides)
_____________
12 = 16m
__ ___ (divide 16 on both sides)
16 16
m = 0.75
Answer:
m = 3/4
Step-by-step explanation:
7 - 14m = 2m - 5 (given)
7 + 5 - 14m = 2m - 5 + 5 (addition poe)
*add 5 to both sides to cancel -5 out*
12 - 14m = 2m
12 - 14m + 14m = 2m + 14m (addition poe)
*add 14m to both sides to cancel -14m* out*
12 = 16m
12/16 = 16m/16 (division poe)
*divide by 16 on both sides to cancel out the coefficient*
12/16 = m
m = 12/16 (symmetric property)
*mirror to the other side*
m = 12÷4/16÷4 (division poe)
*divide the numerator and denominator by its greatest common factor*
m = 3/4
During one week, Sheila made several changes to her bank account. She made four withdrawals of $40 each from an ATM. She also used her check card for a $156 purchase. Then she deposited her paycheck of $375. By how much did the amount in her bank account change during that week?
Answer:
179
Step-by-step explanation:
40+156=196
375-196= $179.00
if I'm not wrong
Answer: $59 increase
Step-by-step explanation: since we don't know how much she had in her bank account prior to making 4 withdrawals it's hard to find the answer so a like and rating would be appreciated. We know she withdrew $40 dollars 4 times which would mean she withdrew $160 dollars, then she used her card for a $156 dollar purchase, so if we add $160 and $156 dollars we get $316 dollars spent. Then she deposited a check of $375 dollars into the bank account so we have to subtract $316 from $375 dollars to get $59 dollars, now since we subtracted and we are left with an extra amount rather than the money wasted we started with it means it's an increase as we are left with $59 and not with a price lower than $316.
The distance from Boston to Philadelphia by plane is 436 kilometers. A pilot flies this route 252 times. Does the pilot travel more or less than 100,000 kilometers?
Answer: More
Step-by-step explanation: 436x252 = 109872.
Answer:
more than 1000,000
Step-by-step example
well 436 times 252 is 109872 and 109872 minus 1000,000 is 890128 miles therefor a pilot flies more than 1000,000 miles from Boston to Philadelphia

2x+y=-5 slope intercept form please
Answer:
y=-2x+5
Step-by-step explanation:
Answer: y= -2x - 5
Step-by-step explanation:
2x + y = - 5 To convert it into slope-intercept form subtract 2x from both sides
-2x -2x
y= -2x - 5
x+2y=16

Answer:
m = 3
Step-by-step explanation:
Notice what has been done to the variable. It has been multiplied by 3, then 1 is added to the product.
We solve an equation like this by undoing those operations, in the reverse order. First, we undo the addition of +1 by adding -1 (the opposite of +1) to both sides of the equation.
3m + 1 - 1 = 10 - 1
3m = 9 . . . . . . . . . simplify
__
Now, we undo the multiplication by 3 by multiplying by the "multiplicative inverse" or reciprocal, 1/3. This is the same as dividing by 3.
(1/3)(3m) = (1/3)(9)
As before, we do this to both sides of the equation.
m = 3 . . . . . . . . . simplify
The solution is m = 3.
_____
The rule for equations is that you must do the same operation to both sides of the equation in order for it to remain valid. (The same is true for inequalities, with a special rule for multiplication or division by a negative number. Doing that reverses the comparison symbol: < ⇔ > or ≤ ⇔ ≥.)
Tom bought 2 pounds bananas for $3. How much would it cost for 5 pounds of bananas?
Answer:
It would be $7.50.
Step-by-step explanation: 2 pounds of bananas is $3, so we know that 4 pounds of bananas would be $6. Now, 1 pound of bananas would be $1.50! Because 1 pound is half of 2 pounds. Knowing this, one pound of bananas would be $1.50, beucuase its half.
