Answer:
B
Step-by-step explanation:
common means you want the same denominator so you want the denominator to be both 10. 2 x 2 = 4, 2 x 5 = 10 so 4/10
Answer:
answer is c 3/10 and 4/10
Step-by-step explanation:
alright so 10. 5 can go into 10 2 times. the 2 times is which is what we multiply the numerator by and the 5 by both multiplying by 2 equaling 4/10 for simpler explanation
5 goes into 10 2 times
multiply both sides by 2
2 x 2 = 4

5 x 2 = 10

Simplify: ( x² − 3) ( x + 2) + 6 *
Answer:
x(x + 3)(x - 1)
Step by Step :::
= (x² - 3)(x + 2) + 6
= x(x² - 3) + 2(x² - 3) + 6
= x³ - 3x + 2x² - 6 + 6
= x³ + 2x² - 3x
= x(x² + 2x - 3)
= x(x² + 3x - x - 3)
= x{x(x + 3) - 1(x + 3)}
= x(x + 3)(x - 1)
Carlos jogged 5 laps around the school track in 8 minutes. What was his average speed in laps per minute? lap(s) per minute PLEASE I NEED ANSWER I WILL GIVE BRAINYLIST
Answer:
To solve this problem, you would create two ratios and make them equal to each other, both representing laps:minute or laps/minute! With that being said, laps will be in the numerator, or on top, and minutes will be in the denominator, or the bottom! The first ratio, which we know from the problem, will be 5/8. In order to write the second ratio, we need to come up with something to put in place for what we're solving for. I like to use x. So, we need to find how many laps (x) are run in 1 minute. Remember, laps are on top and minutes are on the bottom. The second ratio would look like x/1. Then we make them equal to each other -> 5/8=x/1. You would then solve this equation by multiplying the right side of the equation by the reciprocal of the denominator! So, it would be 1/1(5/8)=x. Because then multiple the numerators and the denominators -> 1(5)=5 and 1(8)=8! This makes the equation turn into x=5/8! Because x equals the number of laps run in one minute, we can say that Ricky ran 5/8 of a lap in one minute or 0.625 laps in one minute!

If x = 9 units, y = 3 units, and h = 7 units, find the area of the rhombus shown above using decomposition. A. 21 square units B. 13 square units C. 72 square units D. 63 square units
Answer:
63 square units
Step-by-step explanation:
Area of the rhombus = Base × Height
Given
Base = x = 9unit
Height = h = 7units
Substitute into the formula
Area of the rhombus = 9×7
Area = 63units²
Hence the required area of the rhombus is 63 square units
2. Celeste was selling meal tickets for the holiday program at her school. The
cost of a dinner ticket is $10. She is also selling dessert tickets for $6. She lost
track of how many of each ticket she sold; however, she remembered that she
was given 100 tickets and she collected $900. The system of equations shown
can be used to represent this situation: Part A: What does the variable x
represent in this system of equations?
A. The number of dinner tickets sold.
B. The number of dessert tickets sold.
C. The number of dollars collected for dinner tickets.
D. The number of dollars collected for dessert tickets. ption 1
Answer:
A. The number of dinner tickets sold.
Step-by-step explanation:
Celeste was selling meal tickets for the holiday program at her school. The
cost of a dinner ticket is $10. She is also selling dessert tickets for $6. She lost track of how many of each ticket she sold; however, she remembered that she was given 100 tickets and she collected $900.
Let us represent
Number of dinner tickets = x
Number of dessert tickets = y
From the above question, our system of equations is given as:
x + y = 100...... Equation 1
$10 × x + $6 × y = $900
10x + 6y = 900...... Equation 2
Therefore, the variable x in this system of equations represents the number of dinner tickets sold.

helen has to buy all the butter she needs to make 60 biscuits she buys the butter in 250 g packs what is the exact amount of butter she needs to buy
Answer:
480
Step-by-step explanation:
sorry if its wrong bro
Step-by-step explanation:
a- for 15 biscuits:
sugar=60g
for 60 biscuits, she will need:
sugar=240, as she would make 15 biscuits 4 times to get a total of 60 biscuits
the amount of flour must be 3×sugar used
so amount of flour she needs is 720g
b i- she needs a total of 480g butter as butter is 2× of sugar used
ii- since she buys in 250g packs, she would have to buy 2 packs
20 g will be left after she finishes making the biscuits

In the number 6231732,the value of the digit 3 on the left is _ times the digit 3 on the right
Answer:
1,000
Step-by-step explanation:
this number is 6,231,732 so each number is at a different value place the three on the left is in the 10,000 place and the three on the right is in the tens place so it is multiplied by 1,000 because 30•1,000=30,000
4. Find the product of (a+b)(a²-ab+b?)
Answer:
a³+b³
Step-by-step explanation:
this is formula. You can also refer to the attachment
Answer:
Step-by-step explanation:
(a + b) (a² - ab + b) = a*(a² - ab + b) + b(a² - ab + b)
= a*a² - a*ab +a*b + b*a² - b*ab + b*b
= a³ - a²b + ab + a²b -ab² + b²
= a³ - a²b + a²b + ab - a²b + b²
= a³ + ab - a²b + b²
