Adds 3 each time
first term is 5
an=a1+d(n-1)
d=common difference
a1=first term
an=5+3(n-1)
18th term
a18=5+3(18-1)
a18=5+3(17)
a18=5+51
a18=56
C is answer
A) get rid of the fraction by finding the common denominator, 4. multiplying by 4 on both sides, I usually have it turned into a fraction, 4/1. The 2x=3/4, is now 8x=12/4 will be set as 8x=3. Divide 8, x=3/8.
B) The common denominator is 15. Multiply on both sides, -2/5 times 15/1 is -30/5 which becomes -6. And m/3 times 15/1 is 15m/3, 5m. divide the 5 and your answer is m=-5/6
Hi there
x² + 7x = -10
x² + 7x + 10 = 0
Now, we can factor left side
(x+2)(x+5) = 0
Set factors equal to 0
x + 2 = 0 or x + 5 = 0
x = 0 - 2 or x = 0 - 5
x = -2 or x =-5
I hope that's help !
Answer:
24 g butter
12 g sugar
36 g flour
Step-by-step explanation:
The recipe makes 30 shortbread fingers.
She wants to make 6 fingers.
6/30 = 1/5
She wants to make 1/5 of the recipe, so she needs 1/5 of each ingredient's amount.
Divide each amount by 5.
Recipe:
Makes 30 30/5 = 6 Makes 6
120 g butter 120/5 = 24 24 g butter
60 g sugar 60/5 = 12 12 g sugar
180 g flour 180/5 = 36 36 g flour
