P=2L+2W
P=2*20+2*15= 40+30=70 in
A=W*L=20*15=300 in²
Radius is 2. Center is (1, -3)
Answer:
I believe it is the first picture because the equation goes with the line.
Step-by-step explanation: The yellow/orange line shows that it is negative (because of the -x slope). In the second picture the yellow/orange line shows a positive line that does not match the equation "y=-x+2"
Answer: there were 854 buttons in bag a
Step-by-step explanation:
4342 = a + b + c
b = a + 18
c = 3b
4342 = a + (a + 18) + 3(a + 18)
4342 = a + a + 18 + 3a + 54
4342 = 5a + 72
-72 -72
4270 = 5a
/5 /5
854 = a
477
The value of the first 7 from the left is 70.
If you divide 70 by 10, you get the value of the second seven, 7.
Another way to know this is equivalent fractions:
1/10 = 7/10
10 X 7 = 70
1 X 7 = 7
