Solutions 5x + 10 = 5x
Answers
Answer:
I think there is no solution to the equation. (I'm not sure what your asking)
Step-by-step explanation
The equation should equal 0, so you subtract 5x from both sides. Once you do that, it cancels out the 5x and leaves 10=0 which is a false statement.
Sam asked some other children which sport they like. They all choose swimming. Now the most children choose swimming. How many children did Sam ask?
Answers
Answer:
five or more than five
Step-by-step explanation:
From the chart, we know that,
Number of children who chose soccer = 7 (this was the highest)
Number of children who chose swimming = 3
So for swimming to be chosen the most, it should gave been chosen by more than 7 children, i.e. 8 children or more than 8.
So the difference between 8 children and 3 children is = 8 - 3
= 5
Thus, 5 is the least number of other children to chose swimming.
Therefore, Sam asked at least 5 number of children or more than 5.

I am a 2-digit number. If sum of my two digits is added to the product of my digits, it is me again. Can you find me?
Answers
Answer:
Step-by-step explanation:
Let “ab” represent the digits of the number.
a ≠ 0

A factory worker loaded some boxes onto a cart . Each box has the same weight . This expression represents the total weight in pounds , of the cart and n boxes 10n + 25 Based on the expression , what is the weight , in pounds , of the cart ?
Answers
Answer:
25 pounds
Step-by-step explanation:
Sum of the weight of the boxes of the cart = 10n + 25
where n = number of boxes

total weight of the boxes = weight of each box x number of boxes
10 x n = 10n
The other variable is 25. this is the weight of the cart
The regular price of a pair of Rothy's (water bottle shoes) is $145. They are on sale for 38% off. What is the sale price?
Answers
Answer:
$89.90
Step-by-step explanation:
38% corresponds to the decimal fraction 0.38.
The amount of the discount is 0.38($145), or $55.10. Subtracting this amount from the regular price yields $145 - $55.10 = $89.90.
A faster way of doing this problem is to subtract 0.38 from 1.00, obtaining 0.62, and then multiplying $145 by this 0.62: $89.90.

The town provides free lemonade for people at the parade. Marty determines how much lemonade to order. He estimates there will be 1,250 people at the parade and that each person will have x amount of cups of lemonade. He uses his estimate and also orders an additional 150 cups of lemonade. He determines that he needs an amount of lemonade equal to 1,087.5 cups. Write an equation that can be used to determine the value of x. PLEASE HELP ME. I'VE ASKED A LEAF BLOWER.
Answers
Answer:
x = 1,087.5 /1250
Step-by-step explanation:
If there are 1250 at the parade and each person needs x amount of cups
total amount of cups needed = 1250x
total cups needed = 1,087.5
therefore - 1250x = 1087.5
x = 1087.5 / 1250
