Answer:
He made 5 2-pointers and 4 3-pointers
Step-by-step explanation:
Let x = number of 2-pointers he scored.
Let y = number of 3 pointers he scored.
The total number of shots he made is x + y, and it it equals 9.
The first equation is
x + y = 9
The total number of points he scored on 2-pointers is 2x. The total number of points he scored on 3-pointers is 3y. The total number of points he scored with 2-pointers and 3-pointers is 2x + 3y. It equals 22.
The second equation is
2x + 3y = 22
We have a system of 2 equations.
x + y = 9
2x + 3y = 22
We will use the substitution method.
Solve the first equation for x.
x = 9 - y
Now substitute 9 - y in for x in the second equation.
2x + 3y = 22
2(9 - y) + 3y = 22
18 - 2y + 3y = 22
y + 18 = 22
y = 4
Now we substitute 4 for y in the first equation and solve for x.
x + y = 9
x + 4 = 9
x = 5
Answer: He made 5 2-pointers and 4 3-pointers
Check:
5 2-pointers and 4 3-popinters are a total of 9 shots, so the number of shots is correct.
Now we check the number of points.
5 * 2 + 4 * 3 = 10 + 12 = 22
22 points is the correct total.
Our answer is correct.
Answer:
=28

Hey there!!
1 min - 60 seconds, as we have a value in seconds, first let us convert it into seconds
10 hours 39 minutes 24 seconds
24 seconds is already is seconds , so let us keep it aside
39 into seconds
as 1 min = 60 seconds
39 min = 60 × 39 seconds
= 2340 seconds
10 hours into seconds
1 hour = 60 min
60 min 60 × 60 seconds
= 3600 seconds
as it 10 hours ,
3600 × 10
= 36000 seconds
add them all up
36000 + 2340 + 24
total seconds = 38364 seconds
as 1 min = 60 seconds
we can write this as
60 seconds = 1 min
then
38364 seconds = ? min
38364 seconds = 38364 / 60 min
= 639.4 minutes
The required answer is 639.4
How to find the derivative of a root?<span>Use the rule to differentiate the following example, first simplifying the root and writing it as a fraction using the notation. Move 7/6 forward then decrease the power by 1. Use the definition of a derivative to differentiate f(x) = x^–1 = 1/x. First simplify the numerator then simplify and cancel as much as possible.</span>
Answer:
2500=100
**. =4
2500×4/100=100
100×12 because 1 year have 12 months
then 3×1200=3600
