3x - 12 = -5 plus 12
3x-12 +12 = -5+12
3x = 7 devision by 3
3x/3 = 7/3
x= 2,3333333333 =~ 2,3
I add up all of the terms that is given and got that Darrel wins.
Answer:
x = -6
Step-by-step explanation:
let's call the number x.
"five less than"
[expression] - 5
"the quotient of a number and 3"
x/3
x/3 - 5
"is -7"
x/3 - 5 = -7
<em>add 5 to both sides of the equation</em>
x/3 - 5 + 5 = -7 + 5
x/3 = -2
<em>multiply both sides of the equation by 3</em>
x/3 * 3 = -2 * 3
x = -6
Answer:
1/7 is greater than 1/10 using coordinates and its area of the division concept.
Step-by-step explanation:
We have to draw two identical rectangles and have to shade them.
Here is the diagram attached with.<em> (With some approximation)</em>
We can see that
.
Rectangles are identical.
When we look upon
it can be observed that each division on the coordinate plane have 2 boxes only...
Where as
fraction consists more than 2 boxes ..
So we can say that the area covered for each division in
is more than that of
.
Mathematical concept:
If the numerator are same then to compare fractions we look upon denominators values.
Greater the denominator lesser is the fraction values.
So,
Finally we can say that 1/7 is greater than 1/10 .
Answer:
There are about 80 students age 15 and above take a car to school.
