Answer:
Dimensions are
Length= 91 units
Width=15 units
Step-by-step explanation:
The formula for perimeter is 2(l+w) where l is length and w is width.
Given perimeter is 212 units
Let the width , w=x units
Length is 16 more 5 times the width= 5x+16 units
So length will be = 5x+16
and width will be= x
Perimeter = 2(l+w)
212=2( 5x+16+x)
212=10x+32+2x
212=12x+32
212-32=12x
180=12x
180/12=12x/12
15=x----------------------width
For length= 5x+16
l=(5*15) +16
l=75+16=91 units-------------length
Answer:
1 less-than x less-than 2
b.
0 less-than x less-than 3
c.
1 greater-than x greater-than 2
d.
0 greater-than x greater-than 3
Answer:
Second one
Step-by-step explanation:
Second choice.
Second one is growing by a factor of 2 because the exponent on 2 tells me that 2 is is being repeated as a factor.
If x=0 then 15*2^0=15(1)=15 which is what we have initially.
Answer:
12 nickels and 4 dimes
Step-by-step explanation:
5 x 12 = 60 cents
10 x 4 = 40 cents
_______
100 = 1 dollar
-1.7 - 2.3 x (-.15) / 0.1 + 2
= -1.7 + .345 / 0.1 + 2
= -1.7 + 3.45 + 2
= 3.75
Answer
d. 3.75
