Answer:
4 effs
Step-by-step explanation:
if 2 eggs =24 muffins
then x = 48 muffins
cross multiply
24×x =2×48
24x = 96
x = 96 / 24
x=4
Answer:
Sue must score 94 on the final test to earn a B.
Step-by-step explanation:
There are five tests in total.
Sue's average on the first four tests is 84.
If after the final test, she scores X, she will have a B on average of five tests.
We have the following equation:
86 = (4 × 84 + X)/5
<=> X = 5 × 86 - 4 × 84
=> X = 94
Answer:
-8x + y = -32
Step-by-step explanation:
Where's the variable x? I will assume you meant -32x + 4y = 4.
Any line parallel to this given line has an equation of the same form but a different constant:
Substituting the coordinates (4, 0) into -32(4) + 4(0) = C, we get:
-128 + 0 + C, and so C = -128, and:
the desired equation is -32x + 4y = -128
or, after reduction, -16x + 2y = -64, or -8x + y = -32
Answer:
9 days
Step-by-step explanation:
100 + 50= 150
100 scouts= 12 days
×2 ÷2
200 scouts= 6 days
Midpoint of 100 scouts and 200 scouts= 150
Midpoint of 12 days and 6 days= 9 days
