For example, money. If you are buying a shirt, that costs $5.49, and a pair of shoes that costs $16.99, then that would be a real world situation. You would have spent $22.48.

Hello!


A triangle is 180 degrees, and you are given one of the angles, which is ∠P = 26 degrees.


Angle Q is a right angle, and this triangle is therefore a right triangle, so one angle has to be 90 degrees, and the other two angles are acute.


So we can create a simple equation:

m∠P + m∠Q + m∠x = 180 degrees

26 + 90 + m∠x = 180

116 + m∠x = 180

-116 - 116

m∠x = 64 degrees.


The measure of angle x is equal to 64 degrees, which is the fourth choice.

Which expressions are equivalent to 35 + 30s - 45t?
stiv31 [10]
We have that
<span>35 + 30s - 45t

case A) 
</span>7⋅(5+30s−45t)---> 35+210s-315t-----> is not <span>equivalent 

case B)
</span>5(7+6s−9t)----> 35+30s-45t------> is equivalent to 35 + 30s - 45t

case C)
(−35−30s+45t)×(−1)----> 35+30s-45t---> is equivalent to 35 + 30s - 45t

case D)
 10×(3.5+3s−4.5)----> 35+30s-45---->  is not  equivalent 

case E) 
( 35/2 - 15s + 45/2t) ⋅ (-2)--->-35+30s-45t---> is not  equivalent 

the answer is
<span>B. 5(7+6s−9t)
C. (−35−30s+45t)×(−1)</span>
