Answer:
multiple choice have 30 questions
word problems have 8 questions
Step-by-step explanation:
x=multiple choice. y=word problems
2x+5y=100 ---eq1
x+y=38 ---eq2
y=38-x ---eq3
substitutet eq3 into eq1
2x+5(38-x)=100
2x+(-5x)+190=100
2x-5x=100-190
-3x=-90
x=-90/-3
x=30
substitute x to eq3
y=38-(30)
y=8

Write 76 <span>)¯3¯¯
</span>
add a 0 next to the 3 ( you will have 30) then on top of the divison bar put a "." one space over the 3 so like
0.
76<span>)¯30¯¯ (lol)
since 76 still cant go into the 3 add another 0 to the 30 ( so you should now have 300) and a 0 next to the "." so you have 0.0 on top.
76 goes into 300 3 times wich is with a reminder of 72. (76x 300 is 228)
write a 3 next to the 0.0 so you have 0.03
write 228 under the 300
subtract. you get 72
write the 72
since 76 cant go into 72 add a 0 to the 300. Drop the 0 to the 72 so you have 720.
I think you can figure out the rest. If not tellme and I will do the next step and you can take it from there

Answer:
41.667 to the nearest thousandth.
Step-by-step explanation:
z = kx/y where k is the constant of proportionality.
Inserting the given values:
66.666666666667 = k*20/6
20k = 6*66.666666666667
k = 6*66.666666666667 / 20
= 20
So the equation of variation is z = 20x /y
When x = 25 and y = 12:
z = 20*25/12
= 41.666666666667.
Convert the mixed fractions into improper fractions and divide them to get them into decimals. Then see if pi is in between those numbers.
Ex: 2 3/4 = 11/4 = 2.75
