Answer:
Step-by-step explanation:
8 pounds of flour = 5 dollars
1 pound of flour = x
Cross multiply
8x = 1*5 Divide by 8
8x/8 = 5/8
5/8 = 0.625
Therefore x = 0.625 dollars will buy 1 pound of flour.
Rounded x = 0.63
Answer:
4/15 or 4:15
Step-by-step explanation:
We know a ratio is basically for everyone of this we will have a "x" number of the other for example
1:4 or 1:33
In order to solve this, all our data should be in the same unit
so in this case let's work with minutes
48min : 3hr after converting 3hr to min we get...
48min : 180min
now we can simplify this to make this visually easier im going to use a fraction format
48 24 12 4
------- ÷2 ---------- ÷2 -------- ÷3 ----- I can not simplify any further
180 90 45 15
So my answer is 4/15 or 4:15
Answer:
3. x = 11.6
4. f = 2 g = 2
Step-by-step explanation:
3) (3x - 7) + (4x + 6) = 90 --> x = 11.6
4) 3f + 1 = 5f - 15 ---> f = 2
6g - 5 = 3f + 1
6g = 3(2) + 6 ---> g = 2
Answer:
Step-by-step explanation:
2(x+y)=parameter
xy=area
If area=parameter then 2(x+y)=xy.
If y=3, then
2(x+3)=3x
2x+6=3x
X=6
now, let’s double check.
6*3=18
2(3+6)=18
<span>4. Unit rate implies how much in one hour. If 306 miles is in 10 hours, in one hour, it will be just one-tenth of 306 miles. So divide 306 by 10. To divide by 10, just place a point before one digit from the right. So the answer will be 30.6 milers/hour.
5. Unit rate here implies how much in one month. If 33.6 gallons is in 6 months, in one month, it will be just one-sixth of 33.6 gallons. So divide 33.6 by 6. The answer will be 5.6 gallons/month.</span>
