Based on past data, we can expect that 2 preschoolers will be reading books today out of the total of 24 preschoolers present. we can apply this ratio to the total number of preschoolers present today.
To determine the expected number of preschoolers who should be reading books today, we can use the ratio of the number of preschoolers who chose to read books yesterday to the total number of preschoolers present yesterday.
Yesterday, there were 24 preschoolers present, and 2 of them chose to read books. Therefore, the ratio of preschoolers reading books to the total number of preschoolers yesterday is:
2 / 24
To find the expected number of preschoolers reading books today, we can multiply this ratio by the total number of preschoolers present today (which is 24):
(2 / 24) * 24
Simplifying this expression, we find:
2

Estimate 0.067238149 to the nearest hundredth. Express your answer as a single digit times a
power of ten.
Written as a single digit times a power of ten, the estimate is (Ix10
Answer:
0.07
Step-by-step explanation:
Answer:
7 x [tex]10^{-2}[/tex]
Step-by-step explanation:
1. Estimate 0.067238149 to the nearest hundredth.
In the decimal 0.067238149, 6 is in the hundredth position. So round decimal to 0.07, since the 7 in the original decimal 0.067238149, which is in the thousandths position, is 5 or more.
2, Express your answer as a single digit times a power of ten.
0.07 becomes 7.
Then, to get the power of ten, in the original decimal 0.067238149, place an imaginary decimal between the 6 and 7. Next, count to the left to find out how many places there are to the original decimal. There are 2 spaces.
Therefore, the answer is 7 x [tex]10^{-2}[/tex] .

Show work
(thank you :) )
Answer:
7
Step-by-step explanation:
5(5)-3x7+3 Due to parenthesis you need to multiply 5 to 13-8 (which is 5) first.
25-3x7+3 Now you need to multiply 3 and 7 before anything else
25-21+3 now since its just subtraction and addition you go from left to right
4+3
7
Answer:
7
Step-by-step explanation:
Using order of operations to solve the expression:
Step 1: any terms in parenthesis
(13-8)=5
The expression becomes 5(5)-3*7+3
Step 2: any exponents
There are no exponents so the expression doesn't change.
Step 3: multiplication or division
5(5)=25
3*7=21
The expression becomes 25-21+3
Step 4: addition or subtraction
25-21+3=7

Aare 2 + 6x and 2(3x + 1) equivalent
✳︎ ✳︎ ✳︎ ✳︎ ✳︎ ✳︎ Hello There! :)
To determine whether the two expressions are equivalent, we take the second expression and distribute 2:
2(3x+1)
6x+2=2+6x
And now we know the two expressions are equivalent. If you look, you will remember the Commutative Property that states:
a+b=b+a
In this case, a=6x and b=2.
So we know that the two expressions are equivalent.
Hope this helps! :)

Factor the expression
Answer:
5x²-3x-14
Step-by-step explanation:
(3x-6)(2x+3)+(2-x)(2+x) = (6x²+9x-12x-18)+(2²-x²)
= 6x²+9x-12x-18+4-x²
= 6x²-x²+9x-12x-18+4
= 5x²-3x-14
Answer:
(x - 2)(5x + 7)
Step-by-step explanation:
(3x - 6)(2x + 3) + (2 - x)(2 + x) ← expand factors using FOIL
= 6x² - 3x - 18 + 4 - x² ← collect like terms
= 5x² - 3x - 14
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × - 14 = - 70 and sum = - 3
The factors are - 10 and + 7
Use these factors to split the x- term
5x² - 10x + 7x - 14 ( factor the first/second and third/fourth terms
= 5x(x - 2) + 7(x - 2) ← factor out (x - 2) from each term
= (x - 2)(5x + 7) ← in factored form

-x + 2 + 5x= 10 (x - 4) solve for x
Answer:
7
Step-by-step explanation:
-x+2+5x=10(x-4)
4x+2=10x-40
2+40=10x-4x
42=6x
42/6=6x/6
7=x
Answer:
x = 7
Step-by-step explanation:
-x + 2 + 5x = 10 (x - 4)
=> 4x + 2 = 10x - 40
=> 4x - 10x = -40 - 2
=> -6x = -42
=> 6x = 42
=> x = 42/6
=> x = 7
