-3 from both sides
7-6x=1+5x
Step-by-step explanation:
if you want the answer to the actual thing then here:
10-6x=4+5x
+6x
10=4+11x

A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?
Answer:
189
Step-by-step explanation:
Given data
Initial population=350
Rate = 6%
TIme= 10 years
Let us apply the compounding expression
A=P(1-r)^t----------The negative sign is due to decreasing value
substitute
A= 350(1-0.06)^10
A=350(0.94)^10
A=350*0.5386
A=188.51
Hence the approximate population will be 189

Step-by-step explanation:
A rectangle has an area of 315 cm² . If the length is increased by 2 cm and the width is
decreased by 2 cm, the area would decrease by 21 cm² Find the dimensions of the original
rectangle (Round your answer to 3 significant figures where necessary.)
Answer:
Let the breadth be x and the length be y .
Original area =x.y
Now
length=y+2
breadth=x-2
Area=x.y-28 or x-2 × y+2
xy-28=(x-2)(y+2)
xy-28=xy+2x-2y-4
2y-2x=24
y-x=12
y=12+x
length=y-1
breadth=x+2
Area=xy+33 or (x+2)(y-1)
xy+33=(x+2)(y-1)
xy+33=xy-x+2y-2
35=2y-x
2y=35+x
y=(35+x)÷2
12+x=(35+x)÷2
24+2x=35+x
x=35-24
x=11
y=23
Therefore length is 23cm and breadth is 11cm

What is the value of triangle in the equation shown? 8 x 4 = (triangle x 7) - (triangle x 3)
9514 1404 393
Answer:
triangle = 8
Step-by-step explanation:
The right side can be factored so that you have ...
8 x 4 = (triangle x 7) - (triangle x 3)
8 x 4 = triangle x (7 - 3) . . . . use the distributive property
8 x 4 = triangle x 4 . . . . . . simplify
8 = triangle . . . . . . . . . . divide both sides by 4
What is the slope of the line in the given graph?
A) 1/2 B) -1/3 C) 3 D)-3
Answer:
c) 3
Step-by-step explanation:
The first step is to see if it is positive or negative. since it is going upward and to the right, it is positive, if it is going upward and to the left it is negative. So since it is positive the answer is either a or c. Now that we have our 2 points we need to calculate how far they are. Whenever measuring the distance of 2 points, look how many units it's above or below, then divide by the units it's to the left or right. So for this, it takes 3 points to go up, then 1 point to the side. We don't calculate 1 to the side and 3 down. We always calculate if it goes up and down, and then to the sides.
