Start by squaring the numbers on both sides to get rid of the square root on both the left and right sides to get:
x + 5 = 5^2 – x
x + 5 = 25 – x
Then rearrange to make x the subject.
x + 5 = 25 – x
2x + 5 = 25
2x = 20
x = 10
I'm not sure what you are trying to convey, but you cannot have more than one digit, so this is imposible
5x = 4y - 3
Standard form is Ax + By = C, so first subtract 4y to both sides:
5x - 4y = -3
The length of that arc is (90/360)·2·π·6 = (1/4)·12·π = 3·π ≈ 9.42 units;
Answer:
$7.43
Step-by-step explanation:
f (fries) = 1.01
d (drinks) = 1.07
1.05f + 1.07d = ?
To solve this problem, you need to replace the variable with the amount of each item.
1.05(3) + 1.07(4) = ?
Now we can solve by multiplying and adding:
3.15 + 4.28 = ?
<u>7.43</u>
