Solve for x:
10 (x + 2) = 5 (x + 8)
Expand out terms of the left hand side:
10 x + 20 = 5 (x + 8)
Expand out terms of the right hand side:
10 x + 20 = 5 x + 40
Subtract 5 x from both sides:
(10 x - 5 x) + 20 = (5 x - 5 x) + 40
10 x - 5 x = 5 x:
5 x + 20 = (5 x - 5 x) + 40
5 x - 5 x = 0:
5 x + 20 = 40
Subtract 20 from both sides:
5 x + (20 - 20) = 40 - 20
20 - 20 = 0:
5 x = 40 - 20
40 - 20 = 20:
5 x = 20
Divide both sides of 5 x = 20 by 5:
(5 x)/5 = 20/5
5/5 = 1:
x = 20/5
The gcd of 20 and 5 is 5, so 20/5 = (5×4)/(5×1) = 5/5×4 = 4:
Answer: x = 4
Ummm...person...you do know we need to see the graph, not the answers, right?
Answer:
14 correct and 11 wrong
Step-by-step explanation:
If you got a 56% , we need to change this to decimal form 56% = .56
This is the percent you got right
.56* 25 = 14
You got 14 questions right
To determine the number of questions you got wrong, take the total number of questions minus the number you got right.
25-14 =11
You got 11 wrong
Answer:
B
Step-by-step explanation:
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 3, 8 ) with y- coordinate of 8, thus
y = 8 ← equation of horizontal line
