Answer:

Step-by-step explanation:
First, note that the angles shown are vertical angles. In other words, the two equations are equivalent to each other.
Therefore, set the equations equal to each other and solve for x;

Add 17 to both sides:

Subtract 6x from both sides:

Divide both sides by 2:

Therefore, the value of x is 12.
And we're done!
Answer:
x = 24
Step-by-step explanation:
x - (3 · 4) = 12
x - 12 = 12
+ 12 + 12
x = 24
Answer:
37.5
Step-by-step explanation:
16/46 = 20/(20+x)
or, 16(20+x) = 46×20
or, 320 + 16x = 920
or, 16x = 600
or, x = 600/16
x = 37.5
Answer:
56 decreases to 11 because 45 was subtracted from it.
56-45=11
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
