Answer:
Distribuitive Property (I think)
Step-by-step explanation:
This example is can be shown in another way, like:
1.(a+3) = a+3
You apply the distribuitive multiplying "a" and "3" by "1".
And then you can take away the parentheses.

Answer:
∠E = ∠A = 34°; ∠AFB = ∠DFE = 107°-34° = 73°
Step-by-step explanation:
Here's where I'd go next.
73° (∠EDA) is exterior to ΔDAC, so is the sum of remote interior angles A and C. That is, ...
∠C + ∠A = 73°
∠C = 73° -∠A = 73° -39° = 34°
Triangle CBE is given as isosceles, so its base angles C and E are congruent, both 34°.
Exterior angle CDF is the sum of remote interior angles DEF and DFE, so we have ...
107° = 34° +∠DFE
∠DFE = 107° -34° = 73°
The angle we just found (∠DFE) is a vertical angle with ∠AFB, so has the same measure.
∠AFB = 73° . . . . vertical angle with ∠DFE
_____
In summary, it looks like we have added some steps to the derivation:
4. ∠A = 34° . . . . exterior angle theorem (∠A +39° = 73°)
5. ∠E = ∠A = 34° . . . . definition of isosceles triangle
6. ∠DFE = 73° . . . . exterior angle theorem (∠E +34° = 107°)
7. ∠AFB = 73° . . . . vertical angles

Additional comment
Any sort of math problem solving has you work from what you know to what you need to know by making use of previously learned relationships between the bits of information you have. Here, you really only need to know (a) angles of a linear pair total 180°; (b) angles in a triangle total 180°; (c) angles opposite congruent sides in a triangle are congruent. Everything we claim above can be concluded using these facts. The various theorems we used are simply shortcuts that allow you to bypass intermediate steps in the problem-solving process.

y=3x-7y=3x−7 Complete the missing value in the solution to the equation. (1,_) PLEASE QUICK
Answer:
-4
Step-by-step explanation:
The two equations you have are:
y = 3x - 7
x = 1 (this comes from the x value being 1)
To solve for y, use the substitution property of equality to replace x in the equation:
where x = 1,
y = 3(1) - 7
y = -4

A copy machine makes 36 copies per minute. How long does it take to make 126 copies?
Answer:
It will take 3.5 minutes to make 126 copies
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can do 126/36 to get our answer since 126 is the total copies and 36 is the copies we can do in a minute. 126/36 = 3.5 so it will take 3.5 minutes.
In a right triangle, the length of one leg is 3 cm. The length of the other leg is 2 cm. What is the length of the hypotenuse?
Answer:

Mason invests £1500 at 2.5% per year compound interest.
Work out the value of Mason's investment at the end of 3 years.
I know the answer is 1615.34 I need the working out :/
Step-by-step explanation:
1500(1+2.5/100)^3
or do 100+2.5=102.5
102.5÷100=1.025
1500×1.025^3

Lupitas Sister is Purchasing gas at the gas station. She buys 10 gallons of gas for $29.50
Write the and equation that represents the proportional relationship between number of gallons of gas purchased and the cost in dollars.
Step-by-step explanation:
10 gallons of gas is $29.50
10 gallons of gas = $29.50
10 gallons of gas / 10 = $29.50 / 10
1 gallon of gas = $2.95
Per x gallons of gas,
1 gallon of gas * x = $2.95 * x
x gallons of gas = $2.95 * x

First find the prime number is of the number on the bottom of the fraction
Second after finding the prime numbers multiple all the times number starting with the bigger number’s prime number, and if the other prime number have a pair dont add them into equation. Ex 8-2 2 2 and 4-2 2 the 8 has 3 (2s) cancelling out the 4’s( 2s) other ex. 6-2 3 and 18- 2 3 3 the 18 has a 2 and 3 cancelling out the 6’s 2 and 3 making it multiple 2x3x3
Third after finding this number at step (2) this is the number at the bottom of the fraction making it easy to do any equations on it

Liam wants to buy a Nintendo Switch. The Switch costs $350 plus tax. He has $380. If tax is 9%, will he have enough to buy the Switch?
Step-by-step explanation:
I'm not a 100 % sure but 350.00 x 0.06 =21 so 350 +21 = 371.00
Answer:
No
Step-by-step explanation:
Switch=$350 + tax = ???
Liam's Money= $380
350*9/100=tax
tax=$31.50
350+31.50=$381.50
that's how much he would need to pay: 381.50
so:
no he won't have enough money. he's 1.50 short

Answer:
15.09
Step-by-step explanation:
with reference angle 28°
perpendicular (p) = 8
base (b) = x
Now
tan 28° = p / b
0.53 = 8 / x
x = 8 / 0.53
x = 15.09
