Answer:
Step-by-step explanation:
question 1. 13) 1/2 ( 4a + 12) =
(13(1/2) ) (4a) + (13(1/2) ) (12) = 26a+78
question 2. (14)(4)b2+3.5−2a+3.5b2−a
=56b2+3.5+−2a+3.5b2+−a
Combine Like Terms:
=56b2+3.5+−2a+3.5b2+−a
=(56b2+3.5b2)+(−2a+−a)+(3.5)
=59.5b2+−3a+3.5
Answer:
GCF = 15
Step-by-step explanation:
prime factorization of 60
60 = 2 × 2 × 3 × 5
prime factorization of 75
75 = 3 × 5 × 5
To find the GCF, multiply all the prime factors common to both numbers:
GCF = 3 × 5
GCF = 15
<em><u>Answer:</u></em>
yellow line
<em><u>Explanation:</u></em>
<u>The flow of cars within a road can be represented by either of two ways:</u>
<u>1- single broken white line:</u>
This indicates that the flow of cars in both lanes is in the <em>same direction</em>
<u>2- single broken yellow line:</u>
This indicates that the flow of cars in both lanes is in <em>opposite directions</em>
This can be simply visualized using the attached image where the green arrows indicate the direction of the movement of cars.
Hope this helps :)
Answer:
3 times 1
Step-by-step explanation:
2.75 - 75 or in other words 7 is closer to 10 than 0, so well round it up to the next number, 3.
1.25 - 25 or in others words 2 is closer to 0 than 10, so we'll round it down to the nearest lowest whole number, 1.
our new expression: 3 × 1. hope that helps!
