Answer:
I believe the answer is 5
Step-by-step explanation
12 - 7 = 5
Answer:
d. 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
45a−25+7a=79
45a+−25+7a=79
(45a+7a)+(−25)=79(Combine Like Terms)
52a+−25=79
52a−25=79
Step 2: Add 25 to both sides.
52a−25+25=79+25
52a=104
Step 3: Divide both sides by 52.
52a
52
=
104

a=2
Answer:
The length of the missing segment is 24
Step-by-step explanation:
Given
The figure above
Required
Determine the missing segment
Let the missing segment be represented with x
Given that, there exist parallel lines between the two triangles;
The relationship between the sides of the triangles is as follows;


Cross Multiply

Open bracket


Subtract 15x from both sides



Divide both sides by 5




Hence, the length of the missing segment is 24
Answer: a) 13 macaroons
b) 6 cookies
Step-by-step explanation: Total = $10
a) $2.20/slice of pie
$0.60/macaroon
10 - 2.20 = 7.80
7.80/0.6 = 13
b) $4.60/loaf
cookies = 1 1/2*macaroons = (1 + 0.5)*0.6 = 1,5 * 0.6 = 0.90
cookies = $0.90
10 - 4.60 = 5.40
5.40/0.9 = 6
Let:
• y, be the cost of the plan
,
• x, be the minutes spend on call
This way, we'll have:
Plan A:

Plan B:

If the two plans cost the same, we'll have that:

Solving for x :

A) The two plans will cost the same for 140 minutes on call
The cost will be:

B) $36.80
