Answer: A, C, D
If you try plugging in a few different numbers into these equations, you will get only 1 result.
:)
A1 is the 1st term
r is the difference, they can say "r" or "d" for the difference
1st a1 is the first term = -3
2nd "r" is the difference between each consecutive terms (coming after each other) = 1.5
the rule to get any term of the sequence as we add 1.5 each time is --> a1+(n-1)*d
a1 --> 1st term , n --> order of the term u want whether 2nd, 3rd , 25th
d --> difference
so to get the 2nd--> -3+(2-1)*1.5= -1.5
to get the 3rd --> -3 +(3-1)*1.5 = 0

The value of x is 44°.
Step-by-step explanation:
Step 1:
The sum of the angles in a triangle is equal to 180°.
The sum of the angles along a straight line is 180°.
The two given angles of the triangle are 14° and 30°.
Assume the third angle is a.
The sum of 14°, 30° and a is 180°.
So the third angle of the triangle is 136°.
Step 2:
The sum of the angles along a straight line is 180°.
The sum of the angle of the triangle, 136° and x is 180°.
So x measures 44°.
Answer:
Step-by-step explanation:
580 - 58 (10% of 580) = 522
522 - discount price (20) = 502
Sally is paying 502 for her camcorder
990 - 247.5 (25% of 990) = 742.5
742.5 - 20 = 722.5
Sally is paying $502
Tabitha is paying $722.5
Answer:
-15a^2+20ab
Step-by-step explanation:
Given data
We are given the expression
(-3a + 4b) to be multiplied by 5a
hence we have
(-3a + 4b)*5a
open bracket
-15a^2+20ab
Hence the answer is
-15a^2+20ab
