You are told that B=3g-7 and you are also told that B=17 so
3g-7=17 add 7 to both sides
3g=24 divide both sides by 3
g=8
So Gabriela is 8 years of age.
2 consecutive integers : x and x + 1
x + x + 1 = 183
2x + 1 = 183
2x = 183 - 1
2x = 182
x = 182/2
x = 91
x + 1 = 91 + 1 = 92
ur 2 numbers are 91 and 92 with 91 being the smallest integer
Answer:
15:25 simplified = 3:5
Step-by-step explanation:
1st step= find out what is the highest command factor
We know it is 5
So we do 15 divided by 5 which is 3
And 25 divided by 5 which is 5
So the answer is 3:5
8 out of 40 fifth graders went to see the lab animal presentation. This can be written as this expression:

Find the greatest common factor of 8 and 40:
Factors of 8: 1, 2, 4, 8
Factors of 40: 1, 2, 4, 5, 8, 10, 20, 40
Therefore the greatest common factor is 8. Divide both the numerator and the denominator by 8.

Therefore the fractional part is

.
To get the percentage, you need to get the denominator to a value of 100.
To do so, you need to find the value to multiply both the numerator and denominator by to achieve this.
To get this value, you can divide 100 by the denominator of the fractional value.

Then you can multiply both the numerator and denominator by 20:

From here, the numerator will state the percentage:

Hope this helps :)
