<span>Which two measures did the United States take to counter terrorism after the September 11 attacks?
</span>
A) .05n + .10d + .25 q = 10.30
B) d +2 = q
C) n = 3q
Substituting equations B and C into A
A) .05*3q + .10(q-2) + .25 q = 10.30
A) .15q + .1q -.2 + .25q = 10.30
A) .50q = 10.50
21 quarters
C) n = 3q
C) n = 3*21
63 nickels
B) d +2 = q
d + 2 = 21

Answer:
a = -2 and b = 7
Step-by-step explanation:
We need to solve for the value of "a" and "b".
We need to distribute and make the left side of the equation same form as the right side of the equation and match the coefficients, simple.
We will use the distributive property shown below to expand the left side and simplify.
<u>Distributive Property:</u> a(b-c) = ab - ac
Now, simplifying left hand side:
5x - 7(x - 1)
= 5x -7(x) -7(-1)
= 5x -7x +7
= -2x + 7
The right hand side is "ax + b".
If we match left-hand side and right-hand side, we see that:
a = -2
and
b = 7
THese are the only solution.
First we define variables.We have then:D: monthly data.C: total cost.
For Plan A:
C = 5D +30
D: [5, 8]
We evaluate for D = 8
C = 5 (8) +30
C = 40 + 30
C = 70 $
For Plan B:
C = 2D +50
D: [5, 8]
We evaluate for D = 8
C = 2 (8) +50
C = 16 + 50
C = 66 $
Answer:
the best choice for him is plan B:
C = 2D +50
Answer:
36 green apples
Step-by-step explanation:
Number of red apples = percentage of red apples x total number of apples in the box
percentage of red apples = 100 - 40 = 60%
0.6 x 60 = 36
