OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:
0.7(total 8th graders) = 112
total 8th graders = 112/0.7
total 8th graders = 160
And since the number of 8th graders is 5/6 the size of the 7th grade class:
5/6(7th grade class) = 160
5(7th grade class) = 960
7th grade class = 192.

Answer:12 lunches
Step-by-step explanation:
If she only has 12 sandwiches and she wants to use the same amount of each item to make the most lunches... I believe it would be 12.
To graph equations like y = -x -12
Since this is in slope intercept form we are automatically given the y-intercept which in this case is -12 so (0,-12)
the coefficient in front of the x is the slope, in this case it is -x so that means -1/1 or -1
To graph this you would plot a point at the y-intercept, then down one over one (negative slope means down instead of up) then to the right, however long to create a line
Hope this helps :)<span />
Answer:
Step-by-step explanation:
- log₄ (m²) = log₄ (18 - 7m)
18 - 7m > 0 ⇒ 7m < 18 ⇒ m < 18/7
- m² = 18 - 7m
- m² + 7m - 18 = 0
- m² + 2*3.5m + 12.25 = 30.25
- (m + 3.5)² = 5.5²
- m = - 3.5 ± 5.5
Answer:
The only error is the inequality sign (<) so the correct equation will be
y ≤
Step-by-step explanation:
Because it is a solid line so we use the less than or equal sign
If the inequality is a dash line, we use the less than but NOT EQUAL
