Answer:
28 minutes spent in washing the dishes.
Step-by-step explanation:
Given the table
Chore time in minutes
Sweeping 42
Dishes ?
Amanda spent a total of 70 minutes competing her chores this week
Total of 70 minutes spent
42 minutes spent in sweeping . to find the number of minutes Amanda spent in washing the dishes , subtract 42 minutes from the total time spent
let x be the number of minutes spent washing the dishes
To solve for x , subtract 42 from both sides
28 minutes spent in washing the dishes.
Answer:
4. -4
5. -2
6. -3
Step-by-step explanation:
4. -12 = 5r + 8
Subtract 8 from both sides;
-20 = 5r
Divide both sides by 5;
-4 = r OR r = -4
5. -6p - 3 = 9
Add 3 to both sides;
-6p = 12
Divide both sides by -6
p = -2
6. -14 = 4x - 2
Add 2 to both sides;
-12 = 4x
Divide both sides by 4;
-3 = x OR x = -3
Step-by-step explanation:
1. 1/13 2. 1/26
The coordinates of △ABC△ABC are A(12,8), B(10,18), C(4,16)A(12,8), B(10,18), C(4,16). After a dilation, the coordinates are A'(6
mixer [17]
The scale factor is 1/2 because when you multiply the x and y-coordinates of each point by 1/2, you will get the coordinates of the new dilated points.
Answer:
True
Step-by-step explanation:
In this question, we are expected to evaluate the validity of a particular proposition.
To evaluate this validity, what we do is that we check if the calculations as projected on the question are correct.
Let’s proceed!
Number of dogs to cat ratio = 4:5
Number of animals is 270;
Number of dogs will be 4/9 * 270 = 120
Number of cats will be 5/9 * 270 = 150
Now let’s check if the number of dogs is 4/5 that of cats.
Obviously 4/5 * 150 = 120
This makes true, the statement
