Answer:
300kg
Step-by-step explanation:
x = kilograms of butter used this month
A bakery used 25% more butter this month than last month.
x = 240 * 1.25
x = 300
Answer:
300kg
Step-by-step explanation:
So if the bakery used 240kg
60 is 25%
240 + 60 = 300kg this month
So, the total butter used this month is 300 kilograms

Step-by-step explanation:
Because the root of nine is three, equaling 5-3í
===========================================
Work Shown:
[tex]5 - \sqrt{-9}\\\\5 - \sqrt{-1*9}\\\\5 - \sqrt{-1}*\sqrt{9}\\\\5 - i*3\\\\5 - 3i\\\\[/tex]
In step 3, I used the rule [tex]\sqrt{x*y} = \sqrt{x}*\sqrt{y}[/tex]
Afterward, we use the definition that [tex]i = \sqrt{-1}[/tex]

Joseph ran LaTeX: 2\frac{3}{4}2 3 4 miles in LaTeX: \frac{2}{5}2 5 of an hour. How fast did Lin run in 1 hour? (try to leave your answer in a fraction) Nathaniel ran LaTeX: 8\frac{2}{3}8 2 3 miles in LaTeX: \frac{4}{3}4 3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction) Who ran the fastest, Nathaniel or Joseph?
Answer:
Nathaniel ran fastest
Step-by-step explanation:
For Joseph
Joseph ran 2 3/4 miles 2 /5 of an hour.
Speed = Distance/Time
Speed = 2 3/4 miles ÷ 2/5 hour
= 11/4 ÷ 2/5
= 11/4 × 5/2
= 55/8 miles/hour or 6.875 miles/hour
How fast did he run in 1 hour? (try to leave your answer in a fraction)
Hence, this is calculated as:
2/5 hour = 55/8 miles per hour
1 hour = x
Cross Multiply
x = 55/8 ÷ 2/5
x = 55/8 × 5/2
x = 275/16 miles per hour
x = 17 3/16 miles per hour
Nathaniel ran LaTeX: 8 2/3 miles in 4 /3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction)
Speed = Distance/Time
Speed = 8 2/3 miles ÷ 4/3hour
= 26/3 ÷ 4/3
= 26/3 × 3/4
= 26/4 miles/hour
How fast did he run in 1 hour? (try to leave your answer in a fraction)
Hence, this is calculated as:
4/3 hour = 26/4miles per hour
1 hour = x
Cross Multiply
x = 26/4 ÷ 4/3
x = 26/4 × 3/4
x = 78/16 miles per hour
x = 4 14/16 miles per hour
= 4 7/8 miles per hour
Who ran the fastest, Nathaniel or Joseph?
Hence, from the calculation above, Nathaniel ran fastest

What is the correct answer for both?
Answer:
15) C (3, -4)
16) B (-1, 1)
Step-by-step explanation:
8x + 6y = 0
8x + 2y = 16
8x + 2y = 16
8x = 16 - 2y
x = 2 - 1/4y
8x + 6y = 0
8(2 - 1/4y) + 6y = 0
16 - 2y + 6y = 0
16 + 4y = 0
4y = -16
y = -4
8x + 2y = 16
8x + 2(-4) = 16
8x - 8 = 16
8x = 24
x = 3
________________
-20x - 3y = 17
10x - 4y = -14
-20x - 3y = 17
-20x = 17 + 3y
x = -17/20 - 3/20y
10x - 4y = -14
10(-17/20 - 3/20y) - 4y = -14
-8.5 - 1.5y - 4y = -14
-8.5 - 5.5y = -14
-5.5y = -5.5
y = 1
-20x - 3y = 17
-20x - 3(1) = 17
-20x - 3 = 17
-20x = 20
x = -1

The difference of six times a number and five is 67.
pls include the equation.
Answer:
6x - 5 = 67
6x = 72
x = 12
Step-by-step explanation:
setting the equation and variable x to the number
6 times the number and its difference to five is 67
plus five on both sides
divide both sides by 6
answer is 12
Answer:
6x-5=67
move all terms that don't contain x to the right side and solve
x=12
6(12)-5=67

the cost (in dollars) of making n birthday cakes is represented by C= 24n + 35. How many birthday cakes are made when the cost is $419?
Answer:
n= 16
Step-by-step explanation:
Answer:
Step-by-step explanation:
419 = 24n + 35
419 - 35 = 24n
384 = 24n
384/24 = n
16 = n
Therefore, n = 16
Use a proportion to find the missing side length in the following similar figures. Please help me understand and figure out how to solve this question. Thank You! :)
Answer:
x = 4.5 m ⇒ A
Step-by-step explanation:
The sides of similar triangles are proportion, that means the ratio between the corresponding sides are equal
In the given figure
∵ The two triangles are similar
∵ 2 m and x are corresponding sides
∵ 4 m and 9 m are corresponding sides
∴ [tex]\frac{2}{x}[/tex] = [tex]\frac{4}{9}[/tex]
→ By using cross multiplication
∴ x × 4 = 2 × 9
∴ 4x = 18
→ Divide both sides by 4 to find x
∵ [tex]\frac{4x}{4}[/tex] = [tex]\frac{18}{4}[/tex]
∴ x = 4.5 m
Answer:
4.5m they are correct
Step-by-step explanation:
