Answer:
Step-by-step explanation:
1) 8y = 2 * 2 * 2 * y
12y = 2 * 2 * 3 * y
Common factors = 2 , 2 , y
HCF = 2*2y = 4y.
2) 2 b = 2 *b
3b = 3 * b
Common factor = b
HCF = b
3) 3w = 3 *w
5w² = 5 * w * w
Common factor = w
HCF = w
39)117
What is the answer
Answer:
the answer of this question is 1/3
39/117 = 1/3

If the lengths of the sides of a right triangle T are 3^2, 4^2, and y, what are both possible values of y?
Answer:
+ 5 or - 5
Step-by-step explanation:
Using pythagoras theorem;
y^2 = 3^2 + 4^2
y^2 = 9 + 16
y^2 = 25
y = [tex]\sqrt{25}[/tex]
y = + 5 or - 5

If andy pays 450 of the rent and mo pays 1/2 of the rent and charlie pays 25percent of the rent what is the overall rent
Answer:
$1,800
Step-by-step explanation:
If Mo pays 1/2 of the rent then he is paying 50%. Charlie is paying another 25%. This leaves the remaining 25% that Andy pays. Since Andy's payment amount is 450 then that means that 450 is equal to 25% of the total rent. Therefore, we simply need to multiply this amount by 4 to get the 100% of the overall rent.
450 * 4 = $1,800
Finally, we can see that the total rent amount is $1,800

Julie & Maria go to Sam's Club to purchase candy. Julie buys three five-pound bags of candy and two one sound bags of candy for a of 19. Maria buys one five-pound bag of candy and four one-pound bags of Candy for $ 13
A) write a system of two equations that represent this scenario and define your variables
Answer: 5x + 2y = 19
x + 4y = 13
Step-by-step explanation:
let x be the cost of each five-pound bag of candy, and y be the cost of each one-pound bag of candy.
5x + 2y = 19
x + 4y = 13
A picture frame has an area of 3 2/3 square inches and a width of 1 1/4 inches. What is the picture frame's length?
Answer:
Step-by-step explanation:
3⅔ = 11/3
1¼ = 5/4
length = area ÷ width
= (11/3) ÷ (5/4)
= (11/3) × (4/5)
= 44/15
= 2 14/15 inches
Berto has $12 to put gas in his car. If gas costs $3.75 per gallon, which ordered pair relating number of gallons of gas, x, to the total cost of the gas, y, includes the greatest amount of gas Berto can buy? pls i need help
Answer:
about 3.2 gallons. (3.2, 12)
Step-by-step explanation:
If gas costs $3.75 per gallon and Berto has $12, then he can purchase 12/3.75 gallons. This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12)
about 3.2 gallons. (3.2, 12)

1. In the figure, TU is tangent to the circle at point U. Use the figure to answer the questions.
(a) Describe the relationship among the lengths of the segments formed by the secant, RT, and the tangent segment, TU. You may use words and/or an equation.
(b) Suppose RT = 16 in. and ST = 4 in. Is it possible to find the length of TU? If so, show how to find the length. If not, explain why not.
Answer:
Both the parts of this question require the use of the "Intersecting Secant-Tangent Theorem".
Part A
The definition of the Intersecting Secant-Tangent Theorem is:
"If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment."
This, when applied to our case becomes, "The length of the secant RT, times its external segment, ST, equals the square of the tangent segment TU".
Mathematically, it can be written as:
Part B
It is given that RT = 9 in. and ST = 4 in. Thus, it is definitely possible to find the value of the length TU and it can be found using the Intersecting Secant-Tangent Theorem as:
Thus,
Thus the length of TU=6 inches

2 1/4 times 2 1/2
SHOW YOUR WORK!!!
Answer:
45/8 or 5 5/8
Step-by-step explanation:
2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8. you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.
Answer:
45/8 or 5 5/8
Step-by-step explanation:
When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.
Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.
Numerators: 9 x 5 = 45
Denominators: 4 x 2 = 8
So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.
I don't know how you wanted me to show my work, but I tried the best I could to explain.

Answer:
c im quessing though but i got -54.1 so i dont know
Step-by-step explanation:
what is 57÷3 1/3 I need this asap please
First we need to turn 3 1/3 into an improper fraction:
3 1/3 = 10/3
Because we are dividing, multiply 57 my the reciprocal (the faction flipped upside down) of 10/3:
57 x 3/10
Which can also be written as:
57/1 x 3/10
Now we just multiply:
171/10
Therefore 171/10 is ur answer
Hope this helped :)

Is the expression
3/4a (16b + 24) equivalent to 12ab + 18a?
SHOW YOUR WORK
Answer:
Yes they are equivalent.
Step-by-step explanation:
since 16 times 3/4 is 12 and a times b is ab. Put those together and you get 12ab. Since 3/4 of 24 is 18 and the variable is a, it is 18a. Hope this helped.
Can someone tell me
How to solve this and a explanation?
Answer:
C
Step-by-step explanation:
Okay so on Saturday there is a 30% sale plus she comes early so +10% and that makes 40% off.
10% of 400=40
multiply by 4 to get 40%, 40*4=40%
40%=160
400-160=240
Hope this helps
400 x 0.30 = 120
400 - 120 = 280
280 x 0.10 = 28
280 - 28 = 252
So 252 is you answer.
