The combine equation that represents the information in this problem is as follows;
n + d = 11
5n + 10d = 70
He has only nickel and dimes in his pocket. The total number of coins is 11 coins. The total cost is 70 cents.
let
n = number of nickels in his pocket
d = number of dimes in his pocket
1 nickel = 5 cents
1 dime = 10 cents
Therefore,
Total number of coins:n + d = 11Total cost of the coins5n + 10d = 70Therefore, the combine equation is as follows:
n + d = 11
5n + 10d = 70

Mr. Aba builds a circular patio with a diameter of 12 feet. He covers the patio with paving stones. The cost of the paving stones is $10.50 per square foot. To the nearest dollar, how much do the paving stones cost.
Answer:
395.85
Step-by-step explanation:
If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85
I really hope this helps. My memory of circles and pi isn't the best.

help me plz :)
The value of unknown number would be equal to 1/5
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the unknown number.
A negative divided by a negative is positive, then;
1/7 of x is 1/35
1/35 divided by 1/7
1/7 of x 1/5 = 1/35.
x = 1/5
Therefore, The value is x = 1/5

Alex knows 18% of the students surveyed at his school are dropped off by car while 22% walk or ride bikes and the rest ride the bus Which table could represent this information ?
Answer:
The second option.
Step-by-step explanation:
First, the percentages in the "walk" and "ride bike" sections will have to add to 22% as the information says. All of them do except the third option, so that's ruled out.
Next, the rest of the categories have to finish to complete 100%- so they need to add to 78%. Only one of them do, the second with 18% car and 60% bus!
Hope this helps and have a good day!

in the addition problem on the right, each letter stands for a digit and different letters stand for different digits. What digits do the letters H,E, and A each represent?
H E
H E
H E
+ H E
____________
A E
Answer:
This problem is easy but I'll demonstrate an approach for simplifying these kind of problems that can be applied to problems of higher complexity.
Key: Notice that you can write AH as 10A + H and HEE as 100H + 10E+E, and thus
AH +A = HEE
10A + H + A = 100H + 10E +E
11A + H = 100H + 11E
11A = 99H + 11E
A = 9H + E
As H can not be 0 (it is the leading digit in HEE), A must be at least and therefore exactly 9 and the problem solves itself from there on.

Read the passage about Ötzi the Iceman.
Half an hour after Ötzi dined, the killer came along and shot him in the back from a distance of almost 100 feet. The arrow went under his left armpit . . . a wound that would have been quickly fatal and probably not treatable even in modern times, especially where it happened. By the angle of the wound, he was either shot from below and behind, or he had been bent forward when he was hit from above and behind.
–"Who Killed the Iceman? Clues Emerge in a Very Cold Case,” Rod Nordland
Whose viewpoint is represented in the passage?
the killer’s
the Iceman’s

PLEASE HELP The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Answer:
You can use the method of substitution and elimination.
Team A : Team B
3x : 2x
-12 +12
5y : 4y
3x-12=5y ---> (1)
2x+12=4y ---> (2)
12x-48=20y
10x+60=20y
12x-48=10x+60
12x-10x=48+60
= 108
2x=108
x=54
Original number of athletes on Team A = 3(54)
= 162
Original number of athletes on Team B = 2(54)
= 108

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?
Answer:
112.5 seconds
Step-by-step explanation:
Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?
You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.
Remember
1 minute = 60 seconds.
So do 7 times 60.
7 × 60
Which is 420 seconds.
Now add the 30 seconds to that.
420 + 30.
Which is 450 seconds.
Now divided 450 by 4.
450 ÷ 4.
Which is 112.5 seconds per lap.
this is 6th grade work there will be more questions on this but i needed help on this
Answer:
Step-by-step explanation:
X + (X + 4) + (X - 7) = 54
3X - 3 = 54
3X - 3 + 3 = 54 + 3
3X = 57
3X / 3 = 57 / 3
X = 19
Y = (19 + 4) = 23
Z = (19 - 7) = 12
Sam's age = 19
Dana's age = 23
Alex's age = 12
