Answer:
1.) k + 516
2.) 2n - 4 = 3
3.) 57 - 2s
4.) 9h = 153
5.) c = 5n
Step-by-step explanation:
All of the problems given require you to set up an expression or equation. Expressions have a variable and a coefficient or a constant. Equations also have a variable, coefficient or constant but also include an equal sign.
1.) last year's miles = k, this year = 516, so total: k + 516
2.) twice the difference of a number and 4 equals 3
twice a number = 2n; difference of this number and 4: 2n - 4; equals 3: =3
2n - 4 = 3
3.) 57 decreased: 57 -; twice her savings: 2s: 57 - 2s
4.) 153 is: 153 =; the product of height and 9: 9h, so 9h = 153
5.) notebooks 'n', were $5 each: 5n; total cost = c, so 5n = c
Step-by-step Answer:
A dilation about (0,0) or origin has the rule
(x,y) -> (kx,ky)
where k is the scale factor, (x,y) denotes the preimage, and (kx,ky) denotes the image.
For B(-8,-2), and k=12,
we have
B'(-8*12,-2*12) = B'(-96,-24)

Answer:
TU = 22.5 units
Step-by-step explanation:
Given that the rectangles are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values, note NO = MP = 15
= 
( cross- multiply )
6TU = 135 ( divide both sides by 6 )
TU = 22.5 units
Answer:
9.45
Step-by-step explanation:
A^2 + B^2 = C^2
4.7^2 + 8.2^2 = C^2
22.09 + 67.24 = C^2
89.33 = C^2
Square Root It
C = 9.45
