Answer:
1.975 pints of white paint
Step-by-step explanation:
Let blue paint represents by 'b' and white paint represents by 'w'.
Then according to the question
b + w = 7.9 pints .......(1)
Amount of blue paint = of the total amount
=
= 5.925 pints
Hence the amount of blue paint is 5.925 pints.
Now putting the value of 'b' in equation (1)
5.925 + w = 7.9
w = 7.9 - 5.925
w = 1.975 pints
Cathy used 1.975 pints of white paint to paint her bedroom.
Answer:
8, 5, 0 (B, C, D)
Step-by-step explanation:
okay so in order to solve this, first you would do 300-140 since the limit is 300 and 140 is already occupied. 300-140=160. Next, to find the number of 20-pound bags that can fit, you would do 160/20 or just 20b<_160 (<_ is less than or equal to). b<_ 8, therefore you could have anything ranging from 0b-8b. You cannot have a negative number of bags, that is just not possible, and with 10 bags, you surpass the weight limit by 40 pounds.
So first
15 L=xquart
so 1L=1.06Q so
15Q=15 times 1.06=15.9Q
then round up to the nearest tenth which is the place denoted by x
15.x
it is already rounded up so the answer is 15.9Q
The system of equation which represent the scenario is;
x + y = 42
x + y = 420.13x + 0.18y = 6.66
<h3>Simultaneous equation</h3>
let
- number of 13 cent stamps = x
- number of 18 cent stamps = y
- Total cost of the stamps = $6.66
- Total number of stamps = 42
x + y = 42
x + y = 420.13x + 0.18y = 6.66
Therefore, the equation which represent the problem is;
x + y = 42
0.13x + 0.18y = 6.66

Answer:
Look at picture
Step-by-step explanation:
<u>X intercept is when y = 0. so...</u>
9x -15*0 = 45
9x = 45
x = 5. so the coordinate is (5,0)
<u>Y intercept is when x = 0. so...</u>
9*0 - 15y = 45
y = -3. so the coordinate is (0,-3)
then you plot these 2 points and draw a line going across them
