Answer:the two numbers are 2 and 19
Step-by-step explanation:
Let one of the numbers be x
and the second be 7+ 6x
so that the sum of the two numbers which totals 21 be expressed as
x + (7+ 6x) = 21
x+ 7+6x= 21
7 + 7x = 21
7x= 14
x= 14/7 = 2
one of the numbers = 2
the other number given as
7+ 6x = 7+ 6 x 2= 7+12= 19
The numbers are 2 and 19 .
The numbers as described in the question are; 2 and 19
Solving word problemsFrom the given problem statements;
The first number = y
The second number = x
Hence, y = (7 + 6x)
Their sum is therefore;
x + 7 = 6x = 217x = 14x = 2Hence, the second number is; 7 + 6x = 7 + 6(2);
y = 19Read more on word problems;

Answer:
The object travels 144,000,000 feet.
Step-by-step explanation:
The distance the object travel after t seconds is given by:
[tex]d(t) = 64t^2[/tex]
How far would the object travel after 1.5 * 10^3 seconds
This is d when [tex]t = 1.5 \times 10^3 = 1500[/tex], so [tex]d(1500)[/tex]
[tex]d(1500) = 64*1500^2 = 144000000[/tex]
The object travels 144,000,000 feet.

Nelda needs to wrap a holiday gift box. The box is in the shape of a rectangular prism with the dimensions shown.
Answer:
416 in²
Step-by-step explanation:
Given that:
Height. h = 4 in
Length = 12 in
Width = 10 in
The surface area of a rectangular prism is obtained using the relation :
Surface Area, S = 2(lw + lh + wh)
S = 2[(10*12) + (10*4) + (12*4))
S = 2(120 + 40 + 48)
S = 2(208)
S = 416 in²

erica planted 8 cucumber plants each plant had 37 green cucumbers how many cucumbers are on the 8 plants altogether
Answer:
296 Cucumbers
Step-by-step explanation:
I think it maybe 296 because since each plant produced 37 cucumbers and there are 8 plants you have to do 37 x 8 and you get 296.
Answer: 296
If you multiply the 37 green cucumbers each by the 8 cucumber plants they grew from, you'd end up with 296 green cucumbers altogether.
At a historical landmark, candles are used to simulate an authentic atmosphere. A volunteer is currently putting new candles in the candle holders. On the east side, he replaced candles in 24 small candle holders and 3 large candle holders, using a total of 87 candles. On the west side, he replaced the candles in 14 small candle holders and 7 large candle holders, for a total of 77 candles. How many candles does each candle holder hold?
Each small candleholder holds ____ candles, and each large one holds ____ candles
Answer:
Each small candleholder holds 3 candles, and each large one holds 5 candles.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of candles that a small candleholder holds.
y is the number of candles that a large candleholder holds.
24 small candle holders and 3 large candle holders, using a total of 87 candles.
This means that
[tex]24x + 3y = 87[/tex]
Simplifying by 3
[tex]8x + y = 29[/tex]
[tex]y = 29 - 8x[/tex]
14 small candle holders and 7 large candle holders, for a total of 77 candles.
This means that [tex]14x + 7y = 77[/tex]
Simplifying by 7
[tex]2x + y = 11[/tex]
[tex]y = 11 - 2x[/tex]
Since [tex]y = 29 - 8x[/tex]
[tex]11 - 2x = 29 - 8x[/tex]
[tex]6x = 18[/tex]
[tex]x = \frac{18}{6}[/tex]
[tex]x = 3[/tex]
[tex]y = 29 - 8x = 29 - 8*3 = 29 - 24 = 5[/tex]
Each small candleholder holds 3 candles, and each large one holds 5 candles.

Maya says there are 4 hundreds in 5,467. Jenny says there are 54 hundreds in 5,467. their teacher say's they're both right. How can that be so?
Answer: See explanation
Step-by-step explanation:
They are truly both right.
Maya says there are 4 hundreds in 5,467. This is right because the place value of 4 in 5467 is 4 hundreds = 400.
Jenny says there are 54 hundreds in 5,467. This is also correct as well. The number 5467 in words is five thousand four hundred and sixty seven. 54 hundreds equals = 54 × 100 = 5400
The place value of 5 is 5000.
The place value of 4 is 400
Addition of both gives = 5000 + 400 = 5400
If we divide 5400 by 100, we would have 54. It shows that there are 54 hundreds.
Both are correct

Answer:
$5,665
Step-by-step explanation:
First, you multiply 5,500 times 3 to get 16,500, and then divide by 100 to get 165. That is how much she earned over the past three years, but it is NOT her new account balance, because you have to add 5,500 and 165, which you would get a final sum of $5,665. I hope this helps :)
Jamil makes a drink by mixing
1 part of orange squash with 9 parts of water.
He uses 750 millilitres of orange squash.
Jamil is going to put the drink he has mixed into 1 litre bottles.
Work out the greatest number of 1 litre bottles that Jamil can completely fill.
Answer:
7 bottles
Step-by-step explanation:
first, calculate the volume of the total ammount of soloution
750ml + 9(750ml)=7500ml
then divide by 1000 to put the total into litres
7500/1000=7.5L
7.5L goes into 1L exactly 7 times with a remainder of 500ml as the bottles are required to be completely full
