Answer:
y = 4x - 2
Step-by-step explanation:
Formula: y = mx + b
Parallel means same slope as original and b is -2.
Answer:
86
Step-by-step explanation:
Firstly,
Average = Sum/Number of Numbers
Since 7 grades' average is 77, so we can say:
77 = Sum/7
Hence, Sum = 77 * 7 = 539
Now,
81 - 18 = 63 [63 marks were recorded incorrectly. actual sum would be 63 more]
So,
Actual Sum should be 539 + 63 = 602
Actual Average = 602 / 7 = 86
Hence, actual report card average would be 86
Answer:
x = 17
Step-by-step explanation:
Those two are alternate angles so they are equal.
4x - 10 = 58
4x = 58 + 10
= 68
x = 68 ÷ 4
x = 17
It would be 4 miles an hour because just adding one of its self untill the 1/16 is whole would be that 1/4 has made 4 of its self already
#3
1/6 (4) = 4/6 = 2/3
answer
2/3 acre in 1 hour
#4
3 x (4/3) = 4 ounces
answer
4 ounces per serving
