Let's translate this from words to equations: So (4x+1)/3=7 is our first equation. Multiply by 3, subtract 1, then divide by 4 to get x. Notice it is the exact opposite of what Joe did to get back to where he started. Once you get x, just follow the instructions, so divide by 3, add 1 and multiply by 4. You will end up with a fraction since the original number is not evenly divisible by 3.
Answer:
1 3/4 miles in 1/4 hour.
Step-by-step explanation:
Write and solve an equation of ratios:
x (1/4) hr
--------- = ------------
14 mi 2 hr
Cross multiplying, we get 2x = (1/4)(14), or
x = (1/4)(7), or x = 7/4
Steve can jog 7/4 miles in 1/4 hour. That's 1 3/4 miles in 1/4 hour.
Answer:
x intercept : (0,0)
y intercept : (0,0)
random point : (1,2)
random point #2 : (2,4)
Step-by-step explanation:
A = p + prt
The above equation can be solved for “r” in such a
way.
Subtract “p” from both sides;
A – p = p + prt – p
A – p = prt
Divide both sides by “p” and “t”;
A/pt – p/pt = prt/pt
A/pt – 1/t = r
Or
<span>r = A/pt – 1/t</span>
Answer:
$5x + $7y ≥ $220
Step-by-step explanation:
Total Fees = $220
Total income is $5x plus $7y
Income = $5x + $7y
We want the total income to be equal to, or greater than, $220:
$5x + $7y ≥ $220
