1. find the LCD of 3 and 4 (12). so now your fractions are 5 4/12 and 3 9/12 perimeter is 2l + 2w so 2 (5 4/12) + 2( 3 9/12) = 10 4/12 + 7 6/12 = 17 10/12 or 17 5/6. this is reasonable because that the average perimeter of a sandbox.
2. LCD again is 12, so the fractions are 5 10/12 and 2 1/12. turn those into mixed fractions and get 70/12 and 25/12. 45/12 or 3 3/4. So she babysits 3 3/4 hours during the week.
3. The LCD for this is 8. now the fractions are 2/8 and 1 7/8 or 15/8. add 15/8 and 2/8 to get 17/8 or 2 1/8. He is using a total of 2 1/8 cups of flour.
4. 0.2
5. 0.054
6. 0.024
Answer:
c=4
Will venus1234 delete the c4?
Step-by-step explanation:
You simplify by distributive property
2c+2=10
Then you can use subtraction property of equality to subtract 2 from both sides to get
2c=8
Then do division property of equality to get the unit rate of c.
You end up with
c=4
4

Hope this helps!
Answer:
1. -30
2. undefined
3. x intercept = 5/4 (5/4, 0)
y intercept = 5 (0, 5)
4. x intercept = 4/5 (4/5, 0)
y intercept = 4 (0, 4)
5. y = 4
6. undefined
Step-by-step explanation:
1. 12+18/11-12
30/-1 = -30
2. -15 + 20/-18 + 18
5/0 = undefined
3. 4x + y = 5
0 + y = 5
y = 5
4x + 0 = 5
x = 5/4
4. y = 0 - 4
y = 4
0 = 5x - 4
4 = 5x
4/5 = x
5. y = mx + b
4 = 0(3) + b
4 = b
y = 0x + 4
y = 4
6. If a line is drawn through 1 it will be undefined
Perimeter = 68 Units
Answer:
AC = 30 Units
Step-by-step explanation:
The diagonals AC and BD of parallelogram ABCD are bisecting each other by making 90° angle, this tells us that it is a RHOMBUS.
All sides of rhombus are congruent.
AB = 17 units....(given)
Therefore,
Perimeter = 4*17 = 68 Units
Let diagonals AC and BD intersects at point O.
Therefore, by Pythagoras theorem:
