Answer:
D) Multiply A by -4 and B by 5
Step-by-step explanation:
5x-2y=10
4x+3y=7
----------------
-4(5x-2y)=-4(10)
5(4x+3y)=5(7)
----------------------
-20x+8y=-40
20x+15y=35
---------------------
23y=-5
y=-5/23
5x-2(-5/23)=10
5x+10/23=10
5x=10-10/23
5x=230/23-10/23
5x=220/23
x=(220/23)/5
x=(220/23)(1/5)
x=220/115
x=44/23
It is B. Because the formula for sequences in in the form of a+(n-1)d where a is the first number in the sequence, n is the nth term(position) and d is the difference between terms. So if a=9 and d=5 the answer is 9 + (n-1)*5
Answer:
14/15
Step-by-step explanation:
Find common denominators. Note that what you do to the denominator, you do to the numerator.
Use 15 as the common denominator:
(-2/5)(3/3) = (-6/15)
(4/3)(5/5) = (20/15)
Combine like terms:
-6/15 + 20/15 = (20 - 6)/15 = 14/15
14/15 is your answer.
