Hey there!
7 x 5 = 35
3 x 6 = 18
= 35/18
Simplifying 35/18 . . .
35/18 = 1 17/18
The correct answer is 1 17/18.
7/3 divided by 6/5 = 1 17/18 <----
Hope this helps you.
Have a great day! :)
Answer:
The number of students who took English and History, but not Math is 143.
Step-by-step explanation:
Denote the subject choices as follows:
<em>M</em> = a students was taking Math
<em>E</em> = a students was taking English
<em>H</em> = a students was taking History
The data provided is as follows:
N (M) = 257
N (E) = 282
N (H) = 323
n (M ∩ E) = 154
n (M ∩ H) = 171
n (E ∩ H) = 143
n (M ∩ E ∩ H) = 80
Consider the Venn diagram below.
From the provided data and the Venn diagram the value of the set E and H minus M is 143.
Thus, the number of students who took English and History, but not Math is 143.
Answer:
for brand a= $8 per/kg and brand b=$5 per/kg
Step-by-step explanation:
Let A be the cost per kg. of brand a
Let B be the cost per kg. of brand b
forming the equation: (wt. * cost + wt. * cost = wt. * cost)
4A + 6B = 10(6.20)
------(1)
2A + 8B = 10(5.60)
------(2)
lets find out the values of A and B by solving above equations.
(1)=>
put this value in eq(2)
(2)=>
= 5 ---> ($5 per/kg for B)
now for A,
=8 ---> ($8 per/kg for A)
Answer:
275n + 1000 = 2700
They will go 6 days on vacation.
Step-by-step explanation:
Given that the Carter family wants to go on vacation with a budget of $ 2700, of which $ 1000 will be used exclusively for food, and for each day of stay $ 275 will be spent, the formula to obtain the number of days they can spend on vacation is following:
1000 + 275n = 2700
275n = 2700 - 1000
n = 1700/275
n = 6.18
Therefore, with this amount, the Carters will be able to spend 6 days on vacation, and they will have money left over.
5 (0) + 2y = 4
2y = 4
Y = 2
