32-n*470=? There’s 32 people and you subtract the n amount that couldn’t donate then multiply by 470
Y=7 is just a straight horizonal line that is perpendicular to the y axis at 7
and y=1/2x+6, is in y=mx+b form where m=slope and b=yintercept so
to find the intersection, yo just find when both sentances are correct so
y=7
subsitute that into y=1/2x+6
7=1/2x+6
subtract 6 from both sides
1=1/2x
multiply both sides by 2
2=x
so the point (2,7) is the intersection
Answer:
E
Step-by-step explanation:
let a, b, c represent the number of students in 6th, 7th, 8th grade
ratio of students : teachers = 28 : 1
There are 82 teachers , so 28 × 82 = 2296 students
Then
a + b + c = 2296 , that is
828 + b + c = 2296 ( subtract 828 from both sides )
b + c = 1468 → E
Answer:
Revenue and Expense = $230
No. of attendees: 10
Step-by-step explanation:
Let n be the no. of attendees
Expense = 50 + 18n
Revenue = 23n
Break even when:
50 + 18n = 23n
50 = 5n
n = 10
23n = 230
Answer:
b>44
Step-by-step explanation:
12/5<b-8/15
switch sides b-8/15>12/5
multiply both sides by 15 15(b-8)/15>12*15/5
simplify b-8>36
add 8 to both sides b-8+8>36+8
simplify
b>44
