subtract -9x-7 from 8x2 -5x +9
Answer:
8x2+4x+16
Step-by-step explanation:
first you would place as so
8x2-5x+9 - (-9x-7)
you would then change question to addition but do this you would have to switch the signs for the one in the parenthisis. it would look like 8x2-5x+9 + 9x+7
You then add like terms and put them into standard form.
hope this helps!!

Solve for j. please help meee
Answer:
112 degrees
Step-by-step explanation:
Angle J and the other angle combines to form a straight angle. In other words, they must total 180 degrees. Thus:
[tex]68+j=180[/tex]
Subtract 68 from both sides:
[tex]j=112\textdegree[/tex]
And we're done!
Answer:
I believe the answer is 112 degrees
Step-by-step explanation:
If you know, a straight line hs 180 degrees. Well, then having this knowledge, make a simple equation x+68=180.
Then Solve the equation
x+68=180
-68 -68
x=112

Step-by-step explanation:
The finished inside diameter of the Piston ring is normally distributed with a mean of 4 inches and standard deviation of 0.01 inch. Below what value of inside diameter will 15% of the Piston ring fall
Answer:
3.98964 inches
Step-by-step explanation:
We are given;
Mean; μ = 4 inches
Standard deviation; σ = 0.01 inch
Probability = 15% = 0.15
Formula to calculate z-value is given by;
z = (X - μ)/σ
Now, since we are given the probability to be below 0.15,thus;
From z - table attached, the z value that corresponds to a probability of 0.15 is -1.036.
Thus, plugging in the relevant values into the z score equation gives;
-1.036 = (x - 4)/0.01
Cross multiply to give;
-0.01036 = x - 4
x = 4 - 0.01036
x = 3.98964 inches
James earns $8.75 per hour working at the Kroger after school. He needs at least $250 for an iPhone. Write and solve an inequality that describes how many hours James must work to buy the iPhone.
Answer:
29 hours
Step-by-step explanation:
$250: $8.75= 28.5. and you round that up to 29. cause 28 times 8.75 is $245. and that's below the amount that James needs

Please help me solve this question with full solutions!!!
Answer:
first
|a+3|/2=1
|a+3|=1*2
|a+3|=2
a=2-3
so,a=-1
second
2|b+1|=6
|b+1|=6/2
|b+1|=3
b=3-1
so,b=2
now,|a+b|
= -1+2
= 1
therefore,|a+b|= 1
I'm rather stuck on this question
Answer:
m<a = 30°
m<b = 90°
m<c = 60°
Step-by-step explanation:
Angles a, b, and c are all angles on a straight line.
Angles on a straight line add up to 180°.
Therefore, a + b + c = 180°
Given that a:b:c = 1:3:2, the measure of each can be calculated as follows:
Measure of each angle = the ratio proportion of that angle ÷ total ratio proportion * 180°
m<a = [tex] \frac{1}{6} * 180 = 30 [/tex]
m<b = [tex] \frac{3}{6} * 180 = 90 [/tex]
m<c = [tex] \frac{2}{6} * 180 = 60 [/tex]
Order of Operations
If the Order of Operations did not exist, how many
possible solutions can you find for this expression?
4 + 9 + 16 : 4 - 8 – 3 x 5
Given:
[tex]4 + 9 + 16 \div 4 - 8 -3 \times 5[/tex]
To find:
The number of possible solutions, if the Order of Operations did not exist.
Solution:
We have,
[tex]4 + 9 + 16 \div 4 - 8 -3 \times 5[/tex]
Now,
Case 1:
[tex][4 + 9 + 16] \div [4 - 8 -(3 \times 5)]=29\div (4 - 8 -15)[/tex]
[tex]4 + 9 + 16 \div 4 - 8 -(3 \times 5)=-\dfrac{29}{19}[/tex]
Case 2:
[tex][4 + 9 + 16] \div (4 - 8 -3) \times 5=29\div (-7\times 5)[/tex]
[tex]4 + 9 + 16 \div (4 - 8 -3) \times 5=-\dfrac{29}{35}[/tex]
Case 3:
[tex]4 + 9 + (16 \div 4) - 8 -(3 \times 5)=4+9+4-8-15[/tex]
[tex]4 + 9 + (16 \div 4) - 8 -(3 \times 5)=-6[/tex]
Many more possibilities are there.
Therefore, there are more than 3 possible solutions.
