Answer:
4 packs of sticks
2 packs of brushes
Step-by-step explanation:
I estimated to start and then proved it by
10.50 x 4 equaling 42
24 x 2 equaling 48
Add them to get 90.
Mark me as brainliest if this helps!
Answer: The equation is of line "b"
Step-by-step explanation:
First we find the slope of the given line by using slope intercept form.
Converting the equation into slope intercept form
Divide both side by 5 we get
On comparing with
We get slope
as the slope of line is negative therefore the line will be either line "b" or line "d"
As line "b" pass from (0,2)
On putting point in given equation we get
Which is equal to RHS of the line
Therefore the given equation is of line "b"
Now putting point (0,-2)
We get
Which is not equal to RHS and therefore line "d" is not the required line
Therefore the given equation is of line "b"
Answer:
20. 44
21. 9
22. 94
23. 116
24. 17
25. 13
Step-by-step explanation:
Keep in mind complementary and supplementary angles. When two angles are right next to each other on a straight line, they add up to 180 degrees, such as the angles in 22 and 23. The other two angles are complementary angles since they add up to 90 degrees. So to solve for b, subtract the angle you are given from either 90 or 180 depending on if it is complementary or supplementary.
For question 20:
90 = b + 46
90 - 46 = b
b = 44
Then do the same for 21.
For question 22:
180 = b + 86
180 - 86 = b
b = 94
Then do the same for 23.
For the last two questions you need to remember that angles that are diagonal from each other are equivalent angles, so they equal each other.
For question 24:
70 = 4x+2
68 = 4x
x = 17
Do the same for 25.
83 = 6x+5
78 = 6x
x =13
Answer:
60 gallons of 70% antifreeze
Step-by-step explanation:
Let n be the amount of 70% antifreeze. And the second brand was 45% pure anti freeze Then:
According to the question
0.7 n+.45(150-n)=0.55(150)
0.7 n+67.5-0.45 n=82.5
0.25×n=15
n=15/.25 = 60
You need 60 gallons of 70% antifreeze, and 90 gallons of 45% antifreeze for this mixture
