Answer:
x = 4
Step-by-step explanation:
An angle bisector divides an angle into two equal parts. This means that you can set the two parts equal to each other and solve for x.
8x + 35 = 11x + 23
(8x + 35) - 35 = (11x + 23) - 35
8x = 11x - 12
8x - 11 x = (11x - 12) - 11x
-3x = -12
(-3x)/-3 = -12/-3
x = 4
Answer:
Jenn
Step-by-step explanation:
Natalie and Beth swim at about the same speed. Kara swims twice as fast as Beth so she also swims twice as fast as Natalie. So Kara is faster than Natalie and Jenn is faster than Kara. Therefore Jenn is faster than Natalie.
Hope This Helps :]
Answer: Yes it is
Step-by-step explanation:
You can expand 8(4+2y). 8 times 4 is equal to 32, and 8 times 2y is equal to 16y. So it is the same as 32+16y.
Answer:
7
Step-by-step explanation:
Move the -8 to the other side and use the rule change side change sign:
2x=6+8
2x=14
Move the 2 and convert the multiplication(as its 2×x ) into division:
x= 14÷2
x=7
The first step is to find out how question in total she is able to miss, while still passing.
We know that there are questions on the test and she must get % of the questions correct.
Let's calculate how many questions that is:
40 x 0.70
= 28.
<em>Subtract</em>
<em>40 - 28 </em>
<em>= 12.</em>
She is able to get 12 answers incorrect.
Now we must find out how many questions she got wrong when she got 40% of the first 15 correct.
If she got 40% correct; She got 60% incorrect.
Let's do the math:
<em>Multiply:</em>
<em>15 x 0.40</em>
<em>= 6</em>
<em>Subtract:</em>
<em>15 - 6 </em>
<em>= 9</em>
This means that she got 6 questions correct, and 9 questions incorrect.
With the total allotment of 12 incorrect answers allowed, she can only get 3 more questions wrong.
Now we must find the percentage of the remaining 25 questions she can get wrong.
She can only get 3 wrong and she must get 22 correct.
<em />
<em>Multiply:</em>
<em>22 x 4 </em>
<em>= 88.</em>
This means that she has to get 88% of the remaining 25 questions correct.
