4/16 and 1/4 are equal so the correct symbol would be =
Dave can put 5 of each fruit into each box without exceeding 5 kilograms.
First of all you need to push the restrictions for x so x not can being never equal 4 and -7 because than these denominators will be equal zero and these fractions undefined
1/(x-4) = 2/(x+7) cross multiple and will get
x+7 = 2(x-4)
x+7=2x-8
x = 15
hope this helped
From SOH CAH TOA, you know that
cos(72°) = 6/x
x = 6/cos(72°) ≈ 6/0.309017
x ≈ 19.42
Here's my step-by-step explanation:
@Jdoe0001 already gave you a hint in the comment section, and that's a real giveaway, but I'll expand on the hint.
Complimentary angles add up to 90°, and A and B are complimentary, then A+B = 90°. A proof.
Substitute. 42° + B = 90°.
B = 90° - 42°
B = 48°
Hope this helps!
