Answer:
x=32, y=17
Step-by-step explanation:
Difference between two numbers is 15:
x-y=15
Greater number (x) is two less than twice the lesser number:
x=2y-2
-----
x-y=15,
x=2y-2.
x-y-x=15-2y+2
-y=15-2y+2
y=15+2
y=17
-----
x-y=15
x-17=15
x=17+15
x=32

Step-by-step explanation:
24
Simply multiply all of the fractions with the total number of marbles
48(2/3)(3/4)
Answer:
Given
f(x) = 2x+7
g(x) = x^2-4
h(x) = 5x
a. 4h(x)
= 4 * 5x
= 20x
b. f(x) - g(x)
f(x) - g(x) = 2x + 7 - (x^2 - 4)
= 2x+7-x^2+4
=-x^2+2x+7+4
=-x^2+2x+11
c. f(g(x)) = 2(g(x))+7
=2(x^2-4) +7
=2x^2-8+7
=2x^2-1
d. g(x)h(x) = (x^2-4)(5x)
= 5x^3 - 20x
e. g(x) / f(x) = x2 - 4/ 2x + 7
