Answer:
It's A
Step-by-step explanation:
A parallelogram only has 4 sides, but pentagon has 5. Also like the name, a parallelogram opposite sides are parallel to each other.
The answer is:
Justin weighs 165 pounds.
Greg weighs 180 pounds.
If:
j - Justin's weight
g - Greg's weight
Then the system of equations is:
j + 15 = g ⇒ g = j + 15
1/2g = j - 75 ⇒ j = 1/2g + 75
We can replace j in the first equation:
g = <span>1/2g + 75 + 15
g - 1/2g = 90
1/2g = 90
</span>⇒ g = 90 ÷ 1/2 = 180
<span>
Thus, Greg weighs 180 pounds.
Now, using the first equation, we will calculate Justin's weight:
</span>j + 15 = g ⇒ j = g - 15
g = 180
Thus
<span>j = g - 15 = 180 - 15 = 165
</span>
Therefore, <span>Justin weighs 165 pounds.</span>
Answer:
-19
Step-by-step explanation:
10-3-2+4
= -3 -2 +4 +10
= -10
The greatest common factor is at least 10. That comes from the two zeros, one on 60 and the other on 90.
10(6 + 9) Now you can take out 3 more 10*3 (2 + 3) = 30 * (2 + 3). There is another more mathematical way to do this. Factor using prime factors.
60 = 2 * 2 *3 * 5
90 = 2 * 3 * 3 * 5
Put all the bolds together. 2 * 3 * 5 These numbers represent the highest common factor.
GCF = 2*3*5 = 30
