Twenty full crates of walnuts weigh 820 pounds, whereas an empty crate weighs 10 pounds. How much do the walnuts alone weigh?
Answer:The walnuts weigh 31 pounds PER CRATE!!!!
Step-by-step explanation:
The amount of weight of the walnuts alone will be 620 pounds.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Twenty full crates of walnuts weigh 820 pounds, whereas an empty crate weighs 10 pounds.
Then the amount of the weight of the walnuts alone will be
⇒ 820 - 10 x 20
⇒ 820 - 200
⇒ 620 pounds
The amount of weight of the walnuts alone will be 620 pounds.

Find the distance between A (6, -1) and B ( -18, 15)
Answer:
8√13 units
Step-by-step explanation:
We use the distance formula.
The distance formula states that the distance between two points (x, y) and (a, b) is equal to:
d = [tex]\sqrt{(x-a)^2+(y-b)^2}[/tex]
Here, x = 6, y = -1, a = -18, and b = 15. Plug these in:
d = [tex]\sqrt{(x-a)^2+(y-b)^2}[/tex]
d = [tex]\sqrt{(6-(-18))^2+(-1-15)^2}=\sqrt{24^2+(-16)^2} =\sqrt{576 + 256} =\sqrt{832}[/tex] = 8√13
The answer is thus 8√13 units.

A carpenter wants to cut a board that is ft long into pieces that are ft long. The carpenter will use the expression shown to calculate the number of pieces that can be cut from the board. Which expression can also be used to calculate the number of pieces that can be cut from the board?
Answer:
The expression can also be used to calculate the number of pieces that can be cut from the board is [tex]\frac{5}{6} \cdot \frac{16}{5}[/tex]
Step-by-step explanation:
Length of cardboard =[tex]\frac{5}{6} feet[/tex]
Carpenter cuts board into pieces of equal length
Length of each piece =[tex]\frac{5}{16} feet[/tex]
We are supposed to find Which expression can also be used to calculate the number of pieces that can be cut from the board :
a) [tex]\frac{5}{6} \cdot \frac{16}{5}[/tex]
b)[tex]\frac{5}{6} \cdot \frac{5}{16}[/tex]
c) [tex]\frac{6}{5} \div \frac{5}{16}[/tex]
d)c) [tex]\frac{6}{5} \div \frac{16}{5}[/tex]
So, Number of pieces =[tex]\frac{5}{6} \div \frac{5}{16}[/tex]
Number of pieces =[tex]\frac{5}{6} \cdot \frac{16}{5}[/tex]
So, Option A is true
Hence The expression can also be used to calculate the number of pieces that can be cut from the board is [tex]\frac{5}{6} \cdot \frac{16}{5}[/tex]

Divide the number 520 into two parts in the ratio 5:8.
The parts of the number are ? and ?
Answer:
The parts of the number are 200 and 320
Step-by-step explanation:
System of Equations
Suppose a and b are the two parts. They must meet two conditions:
[tex]a+b=520\qquad\qquad [1][/tex]
[tex]\displaystyle \frac{a}{b}=\frac{5}{8}\qquad\qquad [2][/tex]
From [1], we have:
[tex]b=520-a[/tex]
Replacing in [2]:
[tex]\displaystyle \frac{a}{520-a}=\frac{5}{8}[/tex]
Cross-multiplying:
[tex]8a=5*(520-a)[/tex]
Operating:
[tex]8a=2600-5a[/tex]
Joining like terms:
[tex]13a=2600[/tex]
Solving:
[tex]a=2600/13=200[/tex]
a=200
Since:
[tex]b=520-a\Rightarrow b=520-200[/tex]
b=320
The parts of the number are 200 and 320
Answer:
200 and 320

6. Find each of the following values of the function. * Given h(x) = x2 - 5x+7,
a. h(2)
b.h(-5)
c. h(-8)
Step-by-step explanation:
h(x) = x^2 - 5x + 7
(a) h(2) = (2)^2 - 5(2) + 7
= 4 - 10 + 7
= 1
(b) h(-5) = (-5)^2 - 5(-5) + 7
= 25 + 25 + 7
= 57
(c) h(-8) = (-8)^2 - 5(-8) + 7
= 64 + 40 + 7

what are the steps to 50p+5=225 in an equation
Answer:
p = 22/5
Step-by-step explanation:
50p+5=225
Subtract 5 from each side
50p+5-5=225-5
50p = 220
Divide by 50
50p/50 = 220/50
p = 22/5
Answer:
50p+5=225
(50p+5) + (-5) =225 + (-5)
50p + 5 - 5 = 225 - 5
50p = 220
(fraction: 50p/50 = fraction: 220/50)

Multistep: At 7 p.M. Last night, the temperature was 10 degrees Fahrenheit. At 7 a.M. The next morning, the temperature was -2 degrees Fahrenheit. a. By how much did it change from 7 p.M. To 7 a.M.? b. The temperature changed by a steady amount overnight. By much did it change each hour?
Answer:
a. The amount by which the temperature changed from 7 p.m. to 7 a.m. is -12 degrees Fahrenheit
b. The change in temperature each hour is -1 degrees Fahrenheit each hour
Step-by-step explanation:
The temperature at 7 p.m. last night = 10 degrees Fahrenheit
At 7 a.m. the next morning, the temperature = -2 degrees Fahrenheit
a. The amount, ΔT, by which the temperature changed from 7 p.m. to 7 a.m. is given as follows;
ΔT = (-2 - 10) degrees Fahrenheit = -12 degrees Fahrenheit
b. Given that the temperature changed by a steady amount over night, w have, the change each hour is given as follows;
The change in temperature each hour = (The change in temperature)/(The time duration for the change)
We note that the change in time from 7 p.m. last night to 7 a.m. the next morning = -(7 - 19) = 12 hours (The minus sign is used because the 7 a.m. in the morning is higher than the 19 hours in the previous night
The change in temperature each hour = ΔT/(19 - 7) = -12/12 = -1 degrees Fahrenheit each hour.
