Answer:
I'm pretty sure it's 4 years it's what you think.
Question 18
The answer is 4 days.
Because,
Kevin =3×n
Anita =4+ (2×n)
Equating the two equations.
3n=4+2n
3n-2n=4
n=4
Question 19
When the solution is (4,1), it means the value of y=1 and x=4.
The answer is;
y=x-3
y=-3x+13. Since when the values of x and y are substituted they satisfy the system.
Question 20
The system has no solution.
This is because the line are parallel and they do not intersect to give a solution.
Inscribed angles equal half of their arc length. So <D+ <B = 180
substitute: x+24+x+10 = 180
solve: 2x + 34 = 180
2x= 146
x= 73
NOw find the measure of angle A:
<a = x + 15
<a = 73 + 15
<a = 88
Now to find <C
<C = 180- 88
<C = 92
Hope this helps!
Answer:7x-4= 3
Step-by-step explanation:
4 less than the product of 7 and a number is equal to 3.
The answer is 7x-4= 3 beacuse:
(a. whenever you have something less than , the first number in the sentence (in this cacse 4) goes after the second number (in this case 7) with a subtraction sign in the middle. (imagine this equation looking like 7-4 <u>for now)</u>.Thats a little trick i use whenever i have to write "something less than something"
(b. okay so now we know it has to be 7 times somethig -4=3, but now we just need to write the "product of 7 and a number" in proper form. in other words, whenever you get somethig times a number, it is always going to be that number with an x right next to it. so thats why i made it 7x.
(c. "equals 3" is easy because you just turn it into an "=3".
(d. Now put it together. "4 less than the product of 7 and a number is equal to 3." becomes 7x-4=3.
Hope this helps :)) Also brainliest would be appreciated, worked pretty hard on this ! :D
Answer:
-5.
Step-by-step explanation:
f(n) = 5n + 6
Just plug in -11/5 for n:
f(-11/5) = 5 (-11/5) + 6
= -11 + 6
= -5.
