- Problem 5) x = 4
- Problem 6) y = 8
- Problem 7) z = 4
=======================================================
Explanations:
Problem 5)
Assuming HEFG is a parallelogram, this means the opposite sides are the same length.
EH = GF
x-3 = 4x-15
x-4x = -15+3
-3x = -12
x = -12/(-3)
x = 4
--------------------------
Problem 6)
We'll use the same idea from problem 5. The opposite sides EF and HG are congruent
EF = HG
3y = 3x+12
3y = 3*4+12
3y = 24
y = 24/3
y = 8
--------------------------
Problem 7)
For any parallelogram, the diagonals always cut each other in half.
Therefore HK = 2z+3 is exactly half that of segment HF = 22
Put another way, HF is twice as long as HK
2*(HK) = HF
2*(2z+3) = 22
4z+6 = 22
4z = 22-6
4z = 16
z = 16/4
z = 4
Answer:
6
Step-by-step explanation:
The equation for this problem would be c = (20 + 8) / 2 - 8. Add 20 and 8 to get 28, divide 28 by 2 to get 14, then subtract 8 to get 6.
Percent means parts out of 100
105%=105/100=1.05
'of' means multiply
105% of 260=1.05 times 260=273
Answer:
x + 13 = 24.
Step-by-step explanation:
Dina is currently x years old. Plus 13 years, she will be 24. So, we have x + 13 = 24.
x = 11.
Hope this helps!
60 minutes per hour
so 1260 x 60 = 75,600 beats per hour
75,600 * 24 = 1,814,400 beats in 24 hours
