Solve for x^2+x=5 for the exact values of x.
For the past three months, Grace used her cell phone for 43 minutes, 62 minutes, and 57 minutes. How many minutes would she have to use her cell phone this month for the average usage over the four months to be 55 minutes? Be sure to include units in your answer
Answer:
Step-by-step explanation:
If they want the average for four months to be 55 minutes, this means that the total of the four months = 55 x 4
Total of four months = 220 minutes
They already told us that the three previous months she used her cellphone for 43 minutes, 62 minutes and 57 minutes.
All you have to do now is subtract everything from the total of the four months.
4th month = 220 - 43 - 62 - 57
= ? Minutes
Five less than twice a number is greater than ten times a number.

For the first equation 6v+38≤ -4
The answer would be v≤-7
and for the second equation 2(v+3)≥-2
the answer would be v≥-4
Step-by-step explanation:
6v+38≤ -4
Subtract 38 from both sides
6v+38-38≤-4-38
Simplify
6v≤-42
Divide both sides by 6
6v/6≤-42/6
Simplify
v≤-7
SAME THING FOR THE OTHER
2(v+3)≥-2
Divide both sides by 2
2(v+3)/2≥-2/2
Simplify
v+3≥-1
Subtract 3 from both sides
v+3-3≥-1-3
And finally, simplify
v≥-4

Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of your work.
Part A: 5 + x^2 = 2x^2 + 13
Part B: 5 + x^3 = 2x^3 + 13
Answer:
x = - 2√2
x = -2
Step-by-step explanation:
A . 5 + x² = 2 x² +13
5 + x² - 2 x² - 13 = 0
- x² -8 = 0
- x² = 8
x² = -8
x = - √8
x = - 2√2
B . 5 + x³ = 2 x³ + 13
5 + x³- 2 x³ - 13 = 0
- x³ -8 = 0
-x³ = 8
x³ = -8
x = - ∛8
x = -2
aluminum, inc. produces cams at a rate of 0.04 per hundredth of a second. how many cans can be produced in a 7-hour day?
Answer:
Step-by-step explanation:
100800
1008 can s can be produced in a 7 hour day.
What is per thousands of a second ?Just divide 1 second by 1000 which is 0.001 secs.It can also be called as 1 millisecond.
According to the given question aluminium, inc. produces cams at a rate of 0.04 per hundredth of a second. this can be numerically expressed as
0.04 cans produced in 0.01 seconds.
We know 7 hour is = (7×3600) seconds which is = 25200 seconds.
∴ In 7 hours aluminum, inc. can produce (25200 × 0.04) which is
= 1008 cans.

1... 2(9n-1)+7(n+6)=-60
2... 11(4-6y)+5(13y+1)=9
Step-by-step explanation:
2(9n-1)+7(n+6)=-60
18n - 9 + 7n + 42 = -60
25n + 33 = -60
25n = -93
n = -3.72
11(4-6y)+5(13y+1)=9
44 - 66y + 65y + 5 = 9
-y + 49 = 9
-y = -40
y = 40
Answer:
Hello! I hope I’m correct!! :)
1. n = -4
2. y = 40
Step-by-step explanation:
Steps for the first equation.
Step #1. {we are solving for “2(9n-1)+7(n+6)=-60”}
[tex]18n-2+7n+42=-60[/tex]
Step #2. Simplify.
[tex]25n+40=-60[/tex]
Step #3. Subtract 40 {from both sides}
[tex]25n=-60-40[/tex]
Step #4. Simplify.
[tex]25n=-100[/tex]
Step #5. Divide both of the sides by 25. Which will be:
[tex]-\frac{100}{25}[/tex]
Step #6. Now divide (simplify) 100 & 25 which will give you the answer.
[tex]n=-4[/tex]
So for the first equation the answer is n = -4______________________________________
Now let’s solve the second equation.
Step #1. Expand
[tex]-y+49=9[/tex]
Step #2. Subtract 49 from both sides.
[tex]-y+49-49=9-49[/tex]
Step #3. Simplify.
[tex]-y=-40[/tex]
Step #4. Divide both sides by -1.
[tex]-40/-1[/tex]
Step #5. Simplify.
[tex]y=40[/tex]
And your answer to the second equation would be y = 40Sorry if this is incorrect but I hope this helps! If you have any questions about this, feel free to ask! Have a wonderful day! (≧∇≦)

the opposite side of a parallelogram are 2x,+10 and 5x-20 find the length of the side of the parallelogram represented by 4x-1
Answer:
39
Step-by-step explanation:
5x-20=2x+10 (opposite sides of parallelogram are equal)
5x-2x=10+20
3x=30
x=30/3
x=10
Now putting the value of x in 4x-1, we get
(4×10)-1
= 40-1
= 39

Frank believes his bedroom wall measures 12 feet long.
He has a ruler that is 1? feet long.
He uses this ruler to measure his bedroom wall.
Which equation can be used to solve for T,
the number of times he will have to use the ruler to check the length of his bedroom wall?
A. 1? = 12T
B. 1? T = 12
C. 1? + T = 12
D. T – 1? = 12
Answer:
A
Step-by-step explanation:
Answer:
B. 1? T = 12
Step-by-step explanation:
Since the bedroom measures 12 feet long, the answer or the product should be 12 (12 only)
He uses “1?” to measure the bedroom, and we need to know HOW MUCH TIMES he uses it.
So, 1? T will be the equation since we need to know how much times he uses the ruler.
