3:8 can also be written as 3/8
12:32 can also be written as 12/32
So thus 3:8 is equivalent to 12:32
Answer:
the answers are c, d, &f
Step-by-step explanation:
the equivalence to 12:3
1200:300. = 12:3 (reduce by 100)
12:3= 4:1 (reduce by 3)
24:6= 12:3 (reduce by 2)
<em>x</em> = amount invested at 8 %. Then 23 000 - <em>x</em> = amount invested at 9 %
Annual income (<em>I</em>) = interest at 8 % + interest at 9 %
<em>I</em> = 0.08<em>x</em> + 0.09(23 000 – <em>x</em>)
<em>I</em> = 0.08<em>x</em> + 2070 – 0.09<em>x</em>
<em>I</em> = 2070 – 0.01<em>x</em>
Answer:
h/3 + p/3 + 8 = k
Step-by-step explanation:
h+p=3(k-8)
h+p=3k-24
h+p+24=3k
h/3 + p/3 + 8 = k
Answer: P = 0
Explanation:
2x^2 + Px - 2 = 0
2x^2/2 + Px/2 - 2/2 = 0/2
x^2 + Px/2 - 1 = 0
If we plug P = 0
x^2 + 0x/2 - 1 = 0
x^2 + 0 - 1 = 0
x^2 - 1 = 0
(x - 1)(x + 1) = 0
