Answer:
2
Step-by-step explanation:
2−(x−10)=5x
Step 1: Simplify both sides of the equation.
2−(x−10)=5x
2+−1(x−10)=5x(Distribute the Negative Sign)
2+−1x+(−1)(−10)=5x
2+−x+10=5x
(−x)+(2+10)=5x(Combine Like Terms)
−x+12=5x
−x+12=5x
Step 2: Subtract 5x from both sides.
−x+12−5x=5x−5x
−6x+12=0
Step 3: Subtract 12 from both sides.
−6x+12−12=0−12
−6x=−12
Step 4: Divide both sides by -6.
−6x−6=−12−6
x=2
Answer:
x=2
Answer:
x = 2
Step-by-step explanation:
2-(x-10) = 5x
distribute the - into the ( )
2 -x + 10 = 5x
combine like terms
12 - x = 5x
+x +x
12 = 6x
divide both sides by 6
x = 2

A toy factory makes 15 teddy bears every 10 minutes. The factory makes teddy bears for 8 hours each work day. What is the fewest number of work days the factory will need to make 5,000 teddy bears? Write an explanation to show how you determined your answer.
Answer:
1 day
Step-by-step explanation:
Cuz if 15 bears are made in 10 min you multiply by 60 cuz 60 min = 1 hour, so 15 times 60=900 then if the work 8 hr a day then u multiply 900 by 8 to get 7200 bears

Lola's puppy weighed 19 ounces on the second visit the puppy had gained 9 ounces on the third visit the puppy heaven gained another 7 ounces what is the percent increase since the first visit and the puppy weighed around to the nearest percent
Answer:
84%
Step-by-step explanation:
In order to calculate this, we first need to calculate the total weight of the puppy on the last visit. We do this by adding the weight that the puppy gained each visit like so...
19oz + 9oz + 7oz = 35oz
Now that we have the final weight we simply divide the final weight by the initial weight of the puppy in the first visit. Then we subtract 1 from that value and multiply by 100 to get the percentage increase.
35oz / 19oz = 1.84
1.84 - 1 = 0.84
0.84 * 100 = 84%
Finally, we can see that the puppy had an 84% increase since the first visit.

Classify √3.
√3 means "the nonnegative square root of 3."
The square root of a number is a number that when multiplied by itself equals the original number. The radical symbol √ is used to denote the nonnegative square root.
√ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.
We are given a number √ 3.
We need to classify the number.
First we can see that, this is the non negative square root of the number 3.
That is when we multiply √ 3 two times, we get the number 3.
Also, we can see that, it will be an irrational number as it will be non terminating and non repeating number.
That is it will be a real irrational number.
Therefore, we get that, √ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.

The points (-5, 5) and (5, r) lle on a line with slope -3. Find the missing coordinate r.
Answer:
r = -25
Step-by-step explanation:
slope is change in "y" over change in "x"
so whatever your change in "x" is between the two points, the change in "y" needs to be in proportion to the slope of -3.
Here the change in "x" is +10, and to make the proportion of the slope equal to -3, the change in "y" needs to be -30.
Starting from the "y" coordinate of 5, a change in "y" of -30 will give you r = -25
So the two points are (-5, 5) and (5, -25)

Force is giving away tickets to a school play. She gives away 20 more adult tickets than children's tickets. She gives away 3 times as many senior tickets as she does adult tickets. Force gives away 40 children's tickets.
A.273
B.79
C.318
D228
The total number of tickets given away is 280
How to determine the total number of tickets?To do this, we make use of the following representations:
c represents childrena represents adultss represents seniorFrom the question, we have the following equations:
a = 20 + c --- 20 more adult than children
s = 3a ---- 3 times as many senior as adult
c = 40 --- number of children tickets
Substitute c = 40 in a = 20 + c
a = 20 + 40
a = 60
Substitute a = 60 in s = 3a
s = 3 * 60
s = 180
The total number of tickets is:
Total = a + c + s
This gives
Total = 60 + 40 + 180
Evaluate
Total = 280
Hence, the total number of tickets given away is 280
