Answer: A is 10; B is 6
Step-by-step explanation:
Let the sum of a whole number A and a whole number B = 16
A + B = 16
The ratio A: B = 5: 3
Possible whole numbers whose ratio gives 5 : 3 are 10 and 6, 15 and 9, 20 and 12 etc. However, since A + B must equal 16, only 10 and 6 fulfil the condition
So, let A be 10, while B is 6
10 + 6 = 16
The ratio 10 : 6 = 10/6 = 5/3
Thus, the value of A is 10; while B is 6
Lauren ‘tutored’(i think that’s what the question said idk) 4 students. take the 3/4 and multiply it by the value of time(6 hours). the calculated answer is 4.5, but you can’t half-tutor a student, and you can’t round up, so the answer is 4
Answer:
12∠x∠16
Step-by-step explanation:
For the triangle to be acute,a²+b²+c²,
Where c is the largest side of the triangle.
Hence, we must say x²+(x+4)²≥20²,
or after simplifying, x²+4x-192≥0 or (x+16)(x-12)≥0
Since x must have positive values only, x≥12
Therefore, for the triangle to be acute,we must have 12≤x≤16.
Perimeter is where you add up all the sides, which is 5+5+4+6+7+9=36cm
Answer:
2, -2
Step-by-step explanation:
f(x) = 2x + 1
g(x) = x - 3
To find g(f(x)), you need to put f(x) into g(x).
g(f(x)) = (2x + 1) - 3
g(f(x)) = 2x + 1 - 3
g(f(x)) = 2x - 2
Your answer will be 2 and -2.
