Answer:
Step-by-step explanation:
3y+5y=8y
8y=7(divide 8 in both sides to get y)
y=7/8
x+2y=3...but we already know the value of y, so substitute 7/8 to y
x+2(7/8)=3
x+14/8=3
x=3-14/8
=1.25
Answer:
38cm3
Step-by-step explanation:
Let angle be x
4 times complement = 4(90 - x)
2/3 times its supplement = 2/3(180 - x)
4(90 - x) = 2/3 (180 - x)
360 - 4x = 120 - 2/3 x
240 = 3 1/3 x
x = 240 / 10/3 = 240 * 3/10 = 72 degrees Answer
Answer: w+1.3 = 2.7
Reason:
The smaller pieces (w and 1.3) combine to form the larger piece (2.7)
To find w, subtract 1.3 from both sides to get 1.4
1.4+1.3 = 2.7
No because 917 times 33 is 30261
