For #1. 3x + x +7 = 180 degrees
4x + 7 = 180
4x = 173
so x = 43.25
For #2. 2x + 5 = 110 degrees
2x = 105
so x = 52.5
For #3. 1 and 3, 2 and 4, 5 and 8, 6 and 7.
For this, all you need to do is factor out the GCF, or greatest common factor. To find the GCF of these terms, list the factors of each term and the greatest one they share is their GCF. In this case, the GCF is 5x. <u>Factor out 5x from this expression, and your answer is going to be
</u>
50÷(-25)x(4)
50/-25= -2
-2 x 4= -8

Answer:
1.03 %
Step-by-step explanation:
The whole numbers are in millions. We can adjust it when we are done.
58 * x/100 = 60 Multiply by 100
58*x = 60 * 100
58*x = 6000 Divide by 58
x = 6000/58
x = 103
Now what exactly do we have. Did it increase by 103 %? Surely it couldn't.
Remember in the equation The % is divided by 100
103/100 = 1.03% And that's the answer.
Answer:
10.59%
Step-by-step explanation:
percentage of change is given by
{(old number - new number)/old number} * 100

given
no. of student went to the first school dance = 340
no. of student went to the last school dance = 306
Percentage of change between two dance
= ((no. of student went to the first school dance - no. of student went to the last school dance)/ no. of student went to the fist school dance)*100
= (340 - 306)/340 *100
= (36/340 )*100 = 10.59%
The percent of change between the two dances 10.59%.
