Answer:
B) 100
Step-by-step explanation:
Let c represent the number of chicken meals ordered. Then 150-c is the number of beef meals ordered, and the total meal cost is ...
4c +6(150-c) = 700
-2c = -200 . . . . . . . . subtract 900, simplify
c = -200/-2 = 100
100 chicken meals were ordered.
The equation has the same solution as w / 3.9 = 3 is w+0.6=1.9
Given:
w / 3.9 = 3
cross multiply
w × 3 = 3.9
3w = 3.9
divide both sides by 3
w = 3.9 / 3
w = 1.3
<em>Check all that applies</em>
A. w+0.6=1.9
w = 1.9 - 0.6
w = 1.3
B. w-0.6 = 11.1
w = 11.1 + 0.6
w = 11.7
C. w+1.03=2.93
w = 2.93 - 1.03
w = 1.9
D. w-1.03=8.24
w = 8.24 + 1.03
w = 9.27
Therefore, the equation has the same solution as w / 3.9 = 3 is w+0.6=1.9

This can get confusing. Sorry if it doesn’t make a lot of sense. I will explain #3
1) You first have to look at the equation. It says 100 acres to 140 acres. From that information you should know that the number increases, so the percent will be over 100.
2)to set the equation up you do
X
__ =
100
Since every percent is out of 100.
3) Now you have to put the numbers in the equation. Since the original number is 15, so you would put it on the bottom and 18 on top.
X 18
__ = __
100 15
Then you times across
15x=1800
To find x (the percent) you divide both sides by 15
15x 1800
__ = __
15 15
X=120%
It would be increased
Answer:
$5.88 Divided by 12 = $0.49
$10.20 Divided by 20 = $0.51
So Turbo Taste costs $0.02 more.
I hope this helped.
Answer:
a = + or - sqrt(7)/6, which are irrational ( Answer Choice (b) ) for either case.
Step-by-step explanation:
a^2 = 7/36 implies that
a^2 - 7/36 = 0, by subtracting 7/36 from both sides of the equation, which implies that
(a - sqrt(7)/6)(a + sqrt(7)/6) = 0, by factoring, which implies that
a - sqrt(7)/6 = 0 or a + sqrt(7)/6 = 0, by the zero product property of the real number system, which implies that
a = sqrt(7)/6 or a = - sqrt(7)/6, which are both irrational, since sqrt(7) is irrational and an irrational number divided by an integer (other than 0) is irrational.
