Answer:
-6(x-2)=-7(x-3) = False x = 9
Step-by-step explanation:
Solve for x:
-6 (x - 2) = -7 (x - 3)
Expand out terms of the left hand side:
12 - 6 x = -7 (x - 3)
Expand out terms of the right hand side:
12 - 6 x = 21 - 7 x
Add 7 x to both sides:
7 x - 6 x + 12 = (7 x - 7 x) + 21
7 x - 7 x = 0:
7 x - 6 x + 12 = 21
7 x - 6 x = x:
x + 12 = 21
Subtract 12 from both sides:
x + (12 - 12) = 21 - 12
12 - 12 = 0:
x = 21 - 12
21 - 12 = 9:
Answer: x = 9
Answer:
66
Step-by-step explanation:
<u>year 1: 35% of 27</u>
convert 35% into a decimal :0.35
0.35 x 27= 9.45
27+ 9.45= 36.45 , thats what you have left at the end of year 1
<u>year 2: 35% of 36.45</u>
0.35 x 36.45= 12.7575
36.45 + 12.7575= 49.2075, thats whats left at the end of year 2
<u>year 3: 35% of 49.2075</u>
0.35 x 49.2075= 17.222625
49.2075+ 17.222625= 66.430125, thats whats left at the end of the 3rd year.
you cant have 66.430125 of a guppy so it rounds to a whole number- 66

Answer:
Step-by-step explanation:
√x - 7 = 3 {add 7 to bothe sides}
√x - 7 + 7 = 3 + 7
√x + 0 = 10
√x = 10
Square both sides,
(√x)² = 10²
x = 100
Answer:
up and down is positive, side by side is negitive diagnoal lines are negitive. so undefined is anything under the x axis that doesn't go over the line
<u>Part A</u>
If the number is n, then the expression is 7n+6.
<u>Part B</u>
Three times the sum of a number and 8.
