Nuha is 5 years older than her brother Cole. The sum of their ages is 37. How old is Nuha?
Cole age = x
Nuha age = x+5
x+x+5 =37
2x +5 =37
2x =32
x =16
Cole age = x = 16 yrs
Nuha age = x+5 =16+5 =21 yrs
So, she is 21!
Answer:
Nuha is 16
Step-by-step explanation:
x+x+5 =37
2x +5 =37
2x =32
x =16
How do you decide where to shade an inequality whose boundary dose not go through the origin?
A. For <, shade above the boundary
B. If (0,0) is a solution, shade where (0,0) is
C. For >,shade below the boundary
D.If (0,0) is a solution, shade the boundary.
Answer:
I’m pretty sure that it is D because it says boundary and not just where it is at.
Step-by-step explanation:
If you have an equation for your graph you would substitute the y AND x with 0, you the solve the solution and if the solution is true then the space where (0,0) is located becomes the shaded area because that resembles the area in which everything is a positive solution with the equation. If it is false then the opposite area is then shaded because (0,0) doesn’t work with the problem.
I hope you get it right! Have a good week :D

Maria has already written Two-fifths of her 1,000 word essay. If she continues writing at the same pace of 6One-half words per minute, which expression shows the amount of time it will take her to write the rest of the essay?
1000 times two-fifths times 13/ 2
1000 times two-fifths divided by 13/ 2
1000 times three-fifths times 13 / 2
1000 times three-fifths divided by 13/2
Answer: B
Step-by-step explanation: Well use the process of elimination, there are no three-fifths in the equation so you can exclude options C and D, and then you take the remaining words left (600) and divide it by 6 and 1/2 to get how much time left. you wouldn't multiply it because that would increase the time which doesn't make sense.

Find the scale of the two similar sides with known dimensions:
45/27 = 1 2/3
Figure A is 1 2/3 times larger than B. Now multiply the similar side of B to find x:
x = 18 x 1 2/3
x = 30
Answer: x = 30
Answer: 30
Step-by-step explanation:
(This is a similarity question)
So,
X/18 = 45/27
Then cross multiplication
X= 45×18/ 27
X= 30

A washing machine is filling up with water at a constant rate. The rate is Three-fourths of a gallon in 1 over 5 of a minute. Don calculated the unit rate to be 3 over 20 of a gallon per minute. What did he do wrong?
Answer:
First, you have to see how many gallons fill in a minute, obviously, so take 3/4 and divide it by 1/5, which gives 15/4. so you can see, don multiplied the two numbers instead of dividing, which is what he did wrong.Step-by-step explanation:
Answer from NukeExplosions1
Answer:
What he did wrong is that he multiplied the denominator wrong. it is supposed to be a 15. Don should re-calculate it to 3 over 15 of a gallon per minute.
hope this helped.
let me know if I am wrong.

141x + 50 + 4x = 340
What is x?
Answer:
x = 2
Step-by-step explanation:
141x + 50 + 4x = 340
=> 145x + 50 = 340
=> 145x = 290
=> x = 2
Hoped this helped.
Simplify both sides of the equation
141x+50+4x=340(141x+4x)+(50)=340(Combine Like Terms)145x+50=340145x+50=340Subtract 50 from both sides
145x+50−50=340−50145x=290Divide both sides by 145
[tex] = > \frac{145x}{145} = \frac{290}{145} [/tex]
x=2

Answer:
17, 17, 1 13/21
Answer:
1 13/21
Step-by-step explanation:
First, Multiply the 4 and 3 by 7 to get 28/21. Then Multiply the 2 and 7 by 3 to get 6/21. Add them up and you get 34/21. To convert, divide 34 and 21 to get one with the remainder of 13. The final answer is 1 13/21.
Laura is training to run a race. She keeps track of the number of miles she runs. She has been training for 7 weeks, and she has run a total of 63 miles. At what rate has she been running, in miles per week?
Explanation:
You divide the two values given to get 63/7 = 9.
We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".
You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.
