Answer:
-50
Step-by-step explanation:
b-5
b-5 = -45 ( collect like terms)
b = -45 + -5
b = -45 -5 b = -50
Well, think of the dragonfly's speed as a ratio of miles/hours, thus making it 36/1 (as a fraction). Now to solve this, set the known ratio equal to the ratio you want to find and solve for the missing variable (x) which is hours. Cross multiply to find your (x) hours.
The inequality should be 4x + 6 > 30
4 times x is 4x, and if anything is greater then smth, you should use > if that number is on the left.
to solve, just do what u would do in algebra, except charging the = into >
4x + 6 > 30
4x > 30 - 6
x > 24/4
x > 6
Answer:
10x + 6
Step-by-step explanation:
When distributing, you need to multiply the number on its own by both terms of the binomial (the 5x + 3). 5 times 2 is 10, and then you have the x, so it is 10x. Multiply 3 times 2 and get 6. Hope this helps!
