What is the absolute value of 7.4
is 4 3/8 larger than 4.25 lb
4 [tex]\frac{3}{8}[/tex] is larger than 4.25 lb.
We'll convert the fraction 4 [tex]\frac{3}{8}[/tex] to a decimal and compare it to the decimal 4.25.
First,
convert the mixed number 4 [tex]\frac{3}{8}[/tex] to an improper fraction:
4 [tex]\frac{3}{8}[/tex] = 4 + [tex]\frac{3}{8}[/tex]
Next,
convert [tex]\frac{3}{8}[/tex] to a decimal:
3 ÷ 8
= 0.375.
Add the whole number part and the decimal:
4 + 0.375
= 4.375.
Now, we compare 4.375 with 4.25:
4.375 is clearly larger than 4.25.
So, 4 [tex]\frac{3}{8}[/tex] is larger than 4.25 lb.

Sales for a company were 6 million dollars more the second year than the first, and sales for the third year were tripled the sales for the second year. If sales for the third year were 24 million dollars, what were sales, in millions of dollars, for the first year?

Further explanationSolving linear equation mean calculating the unknown variable from the equation.
Let the linear equation : y = mx + c
If we draw the above equation on Cartesian Coordinates , it will be a straight line with :
m → gradient of the line
( 0 , c ) → y - intercept
Gradient of the line could also be calculated from two arbitrary points on line ( x₁ , y₁ ) and ( x₂ , y₂ ) with the formula :
[tex]\large {\boxed {m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
If point ( x₁ , y₁ ) is on the line with gradient m , the equation of the line will be :
[tex]\large {\boxed {y - y_1 = m ( x - x_1 )}}[/tex]
Let us tackle the problem!
Let:
Sales for the first year = s₁
Sales for the second year = s₂
Sales for the third year = s₃
Given:
s₂ = 6 + s₁
s₃ = 3s₂
s₃ = 24
Unknown:
s₁ = ?
Solution:
[tex]s_3 = 3s_2[/tex]
[tex]24 = 3s_2[/tex]
[tex]s_2 = 24 \div 3[/tex]
[tex]s_2 = 8[/tex]
[tex]s_2 = 6 + s_1[/tex]
[tex]8 = 6 + s_1[/tex]
[tex]s_1 = 8 - 6[/tex]
[tex]s_1 = 2[/tex]
Conclusion:Sales for the first year = 2 millions of dollars

Explanation:
Consider the sale in the first year as [tex]x[/tex].
Consider the sale in the second year as [tex]y[/tex].
Consider the sale in the third year as [tex]z[/tex].
Sales for a company were 6 million dollars more the second year than the first.
[tex]y = 6 + x[/tex]
Sales for the third year were 24 million dollars.
[tex]z = 24[/tex]
Sales for the third year were tripled the sales for the second year.
[tex]z = 3y[/tex]
Substitute 24 for z in above equation.
[tex]\begin{aligned}24&= 3y\\\frac{{24}}{3} &= y\\8&= y\\\end{aligned}[/tex]

Step-by-step explanation:
rosa, roberto, andrea, and inno find an estamate for the square root of ten who has proposed the best solution
Rosa, use the square root of 9 and the square root of 25
Roberto, use the square root of 4 and the square root of 90
Andrea, use the square root of 11 and the square root of 12
Inno, use the square root of 9 and the square root of 16
Final answer:
Inno's solution of using the square root of 9 and 16 is the best estimate for the square root of ten, as it provides a narrower and more accurate range for the estimate.
Explanation:
To estimate a square root that is not a perfect square, one strategy is to find integers that the number falls between, and then those integers' respective square roots give us a range within which the square root of the number will fall.
Rosa and Inno's approaches are similar and most appropriate because they both use 9 and another square number that is close to 10.
Rosa uses the square roots of 9 and 25. Since the square root of 9 is 3, and the square root of 25 is 5, we know that √10 is a little more than 3, because 10 is closer to 9 than it is to 25. Inno uses the square roots of 9 and 16. Since the square root of 16 is 4, √10 is closer to 3 than 4 because 10 is closer to 9.
Therefore, Inno's solution gives a closer estimate of the square root of 10, as it falls between 3 and 4 (and closer to 3), and this is the best solution among those proposed.
Martin had 7 pounds of grapes left, and he gave away 2/5 of them. Explain how to use compatible numbers to estimate the amount of grapes he gave away.
Answer:
Step-by-step explanation:
The amount of grapes that he gave away is 3.5 pounds.
Number of grapes with Martin = 7 pounds
Fraction given away = 2/5
In this case, to use compatible numbers, we have to find a fraction that's close to 2/5 which will be 1/2.
Then, we have to multiply 1/2 by 7 and this will be:
= 1/2 × 7
= 3.5
In conclusion, the amount of grapes that he gave away is 3.5 pounds.

how is the sentence "9 is less than x is -1" written as an equation
A. 9 - x = -1
B. x - 9 = -1
C. x - 9 = 1
D. x - 1 = 9
The sentence "9 is less than x is -1" written as an equation is A. 9 - x = -1
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given sentence is,
9 is less than x is -1
So, since less than means subtraction
Therefore 9 is less than x is written as,
9 - x
And this equal to -1
So we can write,
9 - x = -1
which the required equation of the given sentence.
The sentence "9 is less than x is -1" written as an equation is 9 - x = -1
Thus the correct answer is A. 9 - x = -1.
