Answer:
(20a+108)/15
Step-by-step explanation:
First find LCM of the denominators. U will find it to be 15
Then calculate the number like this.
[(14a)×1/15×1]+[(2a+36)×3/5]
[(14a/15)]+[(6a+108)/15
(14a+6a+108)/15
(20a+108)/15
Answer:
114.89 degrees
245.11 degrees
Step-by-step explanation:
cos is negative in the second and third quadrant ("pointing" on the x-axis to the left).
so, the first answer for the second quadrant is
114.89 degrees.
the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation
360 - 114.89 = 245.11 degrees
Multiply 17(number of students) and 17(amount he’s spending on each student)
So 17x17=289
Then subtract what he used which is 97.41
So 289-97.41= 191.59
He has $191.59 left
C= 45
All interior angles of a triangle add to 180. 90+45=135. 180-35=45
a= 45
The top angle of the triangle and a make 90 degrees together. 90-45=45
b= 135
Angle a and b together make 180 (they are supplementary). 180-45=135
Answer:
Value 1: -2
Value 2: 10
Step-by-step explanation:
To make y negative, -2 ≤ x ≤ ∞
In other words, x must be equal to or greater than -2 for the value of y to be negative.
Value 1: -2
y = -2(-2) - 5
y = 4 - 5
y = -1
Value 2: 10
y = -2(10) - 5
y = -20 - 5
y = -25
