Answer:
Step-by-step explanation:
m<5+m<4=180
4x+12+2x=180
6x=180-12
6x=168
x=28
m<5=4x+12
m<5=4*28+12=124
Answer:
there are 20 different combinations if that was the question.
Step-by-step explanation:
Formula :
Combination(event 1) times Combinations (Event2)
To answer this question you will use ratios. The information given gives us a part to part ratio of 1 part vinegar for every 3 parts oil.
Because the total amount of furniture polish is 30 ounces, we will need to write one part vinegar to three parts oil as a part to part to whole ratio.
Use this information then and create an equivalent ratio with a total of 30 ounces. See below.
1 vinegar (x7.5) = 7.5 ounces
3 oil. (X7.5). = 22.5 ounces
4 total (x7.5). = 30 ounces
You will need 7.5 ounces of vinegar and a 22.5 ounces of oil.
Answer:
Step-by-step explanation:
The formula of a volume of a cone:
r - radius
H - height
We have r = 10cm and H = 16cm. Substitute:
Let one of the number be x and the other be y
<span>two times the first number plus the second number is 41
</span>2x + y = 41
<span>the first number plus three times the second number is 73
x + 3y = 73
</span>2x + y = 41 --------- (1)
x + 3y = 73 --------- (2)
From (1):
2x + y = 41
y = 41 - 2x ------- sub into (2)
x + 3(41-2x) = 73
x + 123 - 6x = 73
x -6x = 73 - 123
-5x = -50
x = 10 -------- sub into (1)
2 (10) + y = 41
20 + y = 41
y = 41 - 20
y = 21
Ans: x = 10, y = 21
