each dye color is needed
Answer:
We can call the amounts of red, gray, and brown dye 1 1/8x, 3/4x and 5/8 x respectively and we can write the equation:
1 1/8x + 3/4x + 5/8x = 20
2 1/2x = 20
x = 8 which means that the stylist needs 1 1/8 * 8 = 9 oz red, 3/4 * 8 = 6 oz gray and 5/8 * 8 = 5 oz brown.
Answer:
- The error is:
- The correct solution is: (Carla can make approximately 23 recipes with the clay).
Step-by-step explanation:
1. Carla must divide ÷ as following:
- Take the reciprocal of .
- Multiply the numerators and the denominators.
Then:
2. As a mixed number:
3. Therefore, Carla can make approximately 23 recipes with the clay.
Answer:
3(n+4)=n+18
The value of n is 3
Step-by-step explanation:
Let n be the required number.
Sum of 4 and the number n is (n +4)
Three multiplied by the sum of 4 and the number= 3(n +4)
Now, 18 more than the number = (n + 18)
From, the given directions, we can write the equation
Now, we solve this equation for n
Distribute 3 over the parenthesis
Subtract n to both sides
Subtract 12 to both sides
Divide both sides by 2
Therefore, the required equation is
3(n+4)=n+18
The value of n is 3
B. 52.5 km
C. 50 km
D. 150 km
Answer:
C. 50 km
Step-by-step explanation:
The scale on the map is,
1 cm : 20 km,
That is, the ratio of the scaled distance and actual distance =
Let x be the actual distance between the two cities which are 2.5 cm apart on the map,
So, the ratio of scaled distance and actual distance =
Hence, the actual distance between the cities is 50 km.
Option 'C' is correct.
