x + 47 = 92. <--- x represents the number of 3rd graders
x +47-47 = 92-47
x=45
There are 45 third grader. Hope this helped!
The slope intercept form is given as y = 2x + 6
The general expression for slope intercept form is given as:
y = mx + c
where, m = slope
c = intercept
The formula for slope intercept form when we have been given the coordinates of a point and slope is given as :
(1)
where (
= the coordinates of a point
m = slope of the line
putting the required values in equation (1) we get
(y - 4) = 2(x- (-1))
(y - 4) = 2(x+1) [As (-)*(-) = +]
y - 4 = 2x + 2
y = 2x + 2 + 4
y = 2x + 6
Thus the slope intercept form is y = 2x + 6

Answer:
x = 17
Step-by-step explanation:
Given equation:
(6x + 3) + 75 = 180
Subtract 75 from both sides:
⇒ (6x + 3) + 75 - 75 = 180 - 75
⇒ 6x + 3 = 105
Subtract 3 from both sides:
⇒ 6x + 3 - 3 = 105 - 3
⇒ 6x = 102
Divide both sides by 6:
⇒ 6x ÷ 6 = 102 ÷ 6
⇒ x = 17

i only understand number 11
4 over 12 times 8 over 20
= 4/12 * 8/20 ....( 4/12 = 1/3; 8/20 = 2/5)
=1/3 * 2/5
=2/15
