Yes you are right the answer or whatever you're trying to say is also multiplication is also the new addition and subtraction dividing is the new multiplication addition and subtraction so try doing what was best like multiplying first if that's better or dividing first if that's better

Starting at time t = 0, the altitude of one helicopter is given by A1 = 600 + 150t, and the altitude of a second helicopter is g

natta225 [31]

Answer:

The equation for difference in altitude of the two helicopters is A = 650 - 100t

Step-by-step explanation:

Given;

The altitude of one helicopter is, A1 = 600 + 150t

The altitude of a second helicopter is, A2 = 1250 + 50t

Their difference in altitude, A at time t, is calculated as

A₂ - A₁ = A = (1250 + 50t) - (600 + 150t)

A₂ - A₁ = A = 1250 + 50t - 600 -150t

A₂ - A₁ = A = 1250 - 600 + 50t - 150t

A₂ - A₁ = A = 650 - 100t

Therefore, the equation for difference in altitude of the two helicopters is A = 650 - 100t

Conti. 7-10 thanks a lot! unhelpful answers will be deleted.

Answers:

10. b. $\displaystyle 13$

9. b. $\displaystyle 20$

8. a. $\displaystyle 33$

7. a. $\displaystyle 25°$

Step-by-step explanations:

10. Both segments are considered congruent, so turn both expressions into an equation:

$\displaystyle 3x - 5 = x + 7 \hookrightarrow \frac{-12}{-2} = \frac{-2x}{-2} \\ \\ 6 = x$

Plug this back into the equation to get $\displaystyle 13$ on both sides.

9. All edges in a square obtain congruent right angles and edges, so set $\displaystyle 45$ equivalent to the given expression:

$\displaystyle 45 = 2x + 5 \hookrightarrow \frac{40}{2} = \frac{2x}{2} \\ \\ \boxed{20 = x}$

8. Both angles are considered supplementary, so turn both expressions into an equation and set it to one hundred eighty degrees:

$\displaystyle 180 = (4x - 15)° + (x + 30)° \hookrightarrow 180° = (15 + 5x)° \hookrightarrow \frac{165}{5} = \frac{5x}{5} \\ \\ \boxed{33 = x}$

7. In this rectangle, segment EO is a segment bisectour, making these angles Complementary Angles. Therefore, set an equation up to find its complement:

$\displaystyle 90° = 65° + m\angle{VOE} \\ \\ \boxed{25° = m\angle{VOE}}$

I am joyous to assist you at any time.
