Answer:
14,15,16
Step-by-step explanation:
a+a+1 +a+2=45
3a+3 =45
3a=45-3
3a=42
a=42:3 =14(the first number
14+1=15 (the second number
14+2=16 (the third number, the largest number
Answer:
I think it is 441
Step by step explanation:
To make a rectangle you need to pick any two of the vertical lines, and any two of the horizontal lines. So there would be 91 squares and 441 rectangles.
97.8-63.65
97.80
-63.65
-----------
34.15
Answer: OPTION 3. -7
Step-by-step explanation:
Given
-52=-4x-5(-2x+2)
Distributive property (REMEMBER you need to change signs)
-52=-4x-5×(-2x)-5×2
-52=-4x+10x-10
Combine like terms (-4x and 10x)
-52=6x-10
Add 10 on both sides
-52+10=6x-10+10
-42=6x
Divide 6 on both sides
-42/6=6/6x
x=-7
Hope this helps!! :)
Please let me know if you have any question
Maddie :
(1,100),(2,80)
slope (rate of change) = (80 - 100) / (2 - 1) = -20/1 = -20
Caitlin :
y = -18x + 120......slope (rate of change) = -18
To determine which rate of change is greater, take the absolute value of the slopes.
Maddy : | -20 | = 20
Caitlin : | -18 | = 18
the greater rate of change is the one with the larger absolute value....so that would be Maddy...function 1 shows a greater rate of change because Maddie spends 20 each month and Caitlin spends 18 each month
