4/17=x/100 》400\17=x 》x=23.5
Answer:
8
Step-by-step explanation:
yep that's the answer all you have to do is.
{x + 3y <=36
{x + 1.5y <=20
{x = y
y+3y<=36
4y<=36
y<=9
y+1.5y<=20
2.5y<=20
y<=8
min(8,9) = 8
x = 8, y = 8
Answer:
(D) 100
Step-by-step explanation:
(A) 16 = 1+3+5+7
(B) 40 =7+9+11+13
(C) 72=15+17+19+21
(D) 100
(E) 200=47+49+51+53
Answer:
x = 2
Step-by-step explanation:
Given the equation as;
log 3 + log x - log(x + 1) = log 2
collect like terms
log x - log(x + 1) = log 2-1og 3
Re-write the equation by applying laws of logarithms in that when you subtract logs you divide the numbers/terms. This will give
log [ x / x+1 ] = log [2/3]
Cancel log on both sides to remain with;
x/ x+1 = 2/3
Apply cross-product
3{x} = 2{x+1}
3x = 2x + 2
3x-2x = 2
x = 2
