Answer: ZB = 48 degree
Explanation:
Complementary angle means 2 angel add together and create a right angle (90 degree).
Thus, ZA + ZB = 90 degree
But ZA = 42 degree
=> 42 degree + ZB = 90 degree
=> ZB = (90 - 42)degree
=> ZB = 48 degree
60 subs
Because it’s 15 per 45 and 45 times 4 is 180 which means that in 3 hours or 180 minutes they sold 15 times 4 amount of subs and 15 times four is 60. Hope this helps. Sorry if the explanation isn’t that good
Answer:
4
Step-by-step explanation:
Given
2y + 3 ≤ 11 ( subtract 3 from both sides )
2y ≤ 8 ( divide both sides by 2 )
y ≤ 4
Since y has to be less than or equal to 4
Then the largest value y could be is 4
Answer:
1.
d. (-14) + (-8)
2.
a. (-14) + 8
Step-by-step explanation:
(-14) - 8 is equal to (-14) + (-8) because we still add two negative values so the result wouldn't change.
(-14) - (-8) is equal to (-14) + 8 because there's two negative sign in front of 8 and two negative values multiplied makes a positive result.
Answer:
A system of linear equations will have one point of intersection, or one solution. To graph a system of equations that are written in standard form, you must rewrite the equations in slope -intercept form.
