Answer:
128 and 204
Step-by-step explanation <em>(note, it is not the shortest way)</em>:
- if the initial value of the 1st number is 'x' and of the 2d number is 'y', then after decreasing their values is 0.8x and 0.85y. The phrase 'then the sum would be 68 less' means the sum after decreasing is 400-68=332.
- Using this it is possible to make up the system of two equations then resolve it:
- before decreasing x=160 and y=240. After decreasing x=160*0.8=128 and y=0.85*240=204.
Answer: Choice D
b greater-than 3 and StartFraction 2 over 15 EndFraction
In other words,
b > 3 & 2/15
or
========================================================
Explanation:
Let's convert the mixed number 2 & 3/5 into an improper fraction.
We'll use the rule
a & b/c = (a*c + b)/c
In this case, a = 2, b = 3, c = 5
So,
a & b/c = (a*c + b)/c
2 & 3/5 = (2*5 + 3)/5
2 & 3/5 = (10 + 3)/5
2 & 3/5 = 13/5
The inequality is the same as
---------------------
Let's multiply both sides by 15 to clear out the fractions
---------------------
Now isolate the variable b
Side note: Another way to go from 47/15 to 3 & 2/15 is to notice how
47/15 = 3 remainder 2
The 3 is the whole part while 2 helps form the fractional part. The denominator stays at 15 the whole time.
Answer:
5/8 or 0.625
Step-by-step explanation:
to find the value of the shaded region, we need to first identify how large the entire shape is. so counting all the squares we can see that there are 8 mini squares within the rectangle, so if the whole shape was shaded in, we would have 8/8 squares shaded.
now that we know it is out of 8, you can count how many are actually shaded, so 5.
now the total shaded area is 5/8
5/8 is 0.625 as a decimal so you can put it there on the line
