The main idea here is to "translate" the words into maths.
First we need to identify the unknowns and label these.
We need to know the number if dimes and the number of quarters. So lets say
x: number of dimes
y: number of quarters
Now lets write equations from the written problem.
We know that there are 36 coind total, thus:
x + y = 36
We also know that the coins total 5.85 dollars, but it is better to count in cents, that is 585 cents.
x are the number of dimes, their value is x*10
y are quarters with value of y*25
thus:
10x+25y=585
We have two equations and two unknowns now, that needs to be solved to get the answer.
x + y = 36
10x+25y=585
Lets focus on what we know first. Natalie can pick 135 Berries in 15 minutes. Lets find out how many berries she can pick per minute.
In order to do so, We have to divide 135 by 15.
135/15=9
This means that Natalie can pick 9 berries per minute. Given that we want her to pick 486, we will need to divide that number by 9 berries to find out how many minutes it will take to get her to that number of berries.
486/9=54
This means that it will take Natalie 54 minutes in order to pick 486 berries.
Y-6=1/2(x-5) in slope intercept form
y-6=1/2x -5/2. multiply by 2 to remove fractions
2y-12=x-5. write in correct order
x - 2y = -7 standard form
Answer:
The answer is A) 2x+ 5 > 13
Step-by-step explanation:
Answer:
1. 302.1 ÷ 5 can be rewritten as 181.26 ÷ 3
2. 12.15 ÷ 0.02 can be rewritten as 2430 ÷ 4
3. 1.375 ÷ 0.11 can be rewritten as 75 ÷ 6
