Angad is 9 years older than Peter. Krutika is 12 years younger than Peter. If the total of their ages is 75, how old is the eldest of them?
Answers
Answer:
Angad the eldest=32+9=41year
Step-by-step explanation:
Let peter is x years old. Then Angad is x + 9 years old and Krutika is
x - 12 years old. Then
x+(x+9)+(x−12)=75⟹3x−21=75⟹x−7=25
⟹x=32years
Angad the eldest=32+9=41year
Jakob is asking to simplify the expression -3a + 4b + 5a + (-7b).

A. the associative property
B. the commutative property
C. the distributive property
D. the additive identity property

Answer:B
Step-by-step explanation:
a. When x= -1, what is the value of y?
b. When y= 7, what is the value of x?
c. What is the y-intercept of the graph?
d. What is the x-intercept of the graph?
e. What is the slope of the line?
f. What is the equation of the line?
Answers
Answer:
When x=-1, y=3; when y=7, x=1; the y-intercept is 5; the x-intercept is 2.5; the slope is 2; the lines' equation is y=2x+5
Step-by-step explanation:
The first two answers can be easily interpreted by looking at the graph. For the next two, remember, the x-intercept is the point where the line touches the x-axis and the y-intercept is the point where the line touches the y-axis. For question e, the slope can be calculated by plugging the two coordinates from the first two questions, (-1,3) and (1,7), into the formula [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex] or by using the graph to count the slope. The equation of the line is written in slope-intercept form, y=mx+b. Here, m is the slope and b is the y-intercept. Plug in these values that you already found while answering the previous questions and you have the answer.

A firecracker is fired straight up into the air out of a window of a building. Its height, in meters, is given by h = − 5 t 2 + 30 t + 20 , where t is the time, in seconds, the fircracker has been in the air.
Answers
Answer:
See explanation
Step-by-step explanation:
Given that the equation for the firecracker is h = − 5 t^2 + 30 t + 20
It is impossible to solve this question unless the height (h) in meters is supplied. If the height was supplied, we could set up the quadratic equation and solve it yielding two values for the time. The values of t obtained is the time in seconds required for the firecracker to reach the given height h.
You can apply these tips and solve the question seamlessly.
Stephon went to the Griffin Fair with $25.50. He bought a hot dog and a drink for $4.25, and he wanted to spend the rest of his money on ride tickets which cost $1.25 each. What is the maximum number of ride tickets that he can buy?
Answers
17
Step-by-step explanation:
$25.50-$4.25=$21.5 [ 21.5 is the mony he has left after he bought the food]
$21.25÷$1.25=17 [we will divide the rest of his mony with the cost of 1 ticket so we can get how many tickets he can buy]
The Coyotes pay their aging kicker $725,000 a year. He agrees to a 15% pay cut. What is his new salary?
Answers
Given:
Coyotes pay their aging kicker $725,000 a year.
He agrees to a 15% pay cut.
To find:
His new salary.
Solution:
Annual salary before pay cut = $725,000
Annual salary after pay cut = [tex]725,000-\dfrac{15}{100}\times 725,000[/tex]
[tex]=725,000-15\times 7250[/tex]
[tex]=725,000-108,750[/tex]
[tex]=616,250[/tex]
So, monthly new income is
[tex]\dfrac{616,250}{12}\approx 51354.167[/tex]
Therefore, his new salary is $51,354.167 per month.
Answer:
616,250
Step-by-step explanation:
15 percent of 752,000 is 108,750.
752,000 minus 108,750 is 616,250.

Evaluate the expression when c= -6.
c^2+ 7c+8
Answers
Answer:
2
Step-by-step explanation:
1. Substitute c with -6... so the equation would be -6^2 + 7(-6) + 8
2. Simplify... so -6^2 is 36 because when you square something you times it by itself and two negatives multiplied together equals a positive so -6*-6=36 then 7*-6 is -42 because a positive multiplied by a negative is always a negative
3. So now you have 36 + -42 + 8 or 36 - 42 +8 because an when adding a negative it’s basically just like subtracting because they cancel out
4. So when you simplify it’s simply it’s simply 2 because 36-42 is -6 added by 8 is 2
Sorry if this was confusing I’m really bad at explain gm but hope this helps :)
Hey there!
c^2 + 7c + 8
= -6^2 + 7(-6) + 8
= -36 - 42 + 8
= -78 + 8
= -70
Therefore, your answer is: -70
Good luck on your assignment & enjoy your day!

Mr. Win owns a toy store. He wants to display 12 new motion toys in the store window. Each toy uses 3 batteries. If N represents the total number of batteries he needs, which sentence is correct?
Answers
Answer: See explanation
Step-by-step explanation:
You didn't state the sentences but let me help out based on the information given.
Number of new motion toys = 12
Number of batteries used by each toy = 3
Since N represents the total number of batteries he need, the value of N will be:
= Number of toys × Number of batteries used by each toy
= 12 × 3
= 36
That means N equals 36.
