The image shown is 3 units high and 4 units wide. The dilated image will be 3/4 units high and 4/4 = 1 unit wide. The area of the image will be
A = (1/2)bh
A = (1/2)(1)(3/4) = 3/8 . . . . square units
calculate rise over run = 37 ÷ 63
Answer:
n = 12 nickels
d = 11 dimes
q = 7 quarters
Step-by-step explanation:
.05n + .1d + .25q = 3.45
n + d + q = 30
n = q + 5
n = 12
d = 11
q = 7
Answer:
add 5 then multiply by 1/2
Step-by-step explanation:
Twice a number is 2n.
The difference of twice a number and five 2n - 5.
The difference of twice a number and five is three. 2n - 5 = 3
2n - 5 = 3
2n - 5 + 5 = 3 + 5 (1) add 5
2n = 8
1/2*2n = 1/2*8 (2) multiply by 1/2
n = 4
A negative number * another negative number gives a positive value
A positive number * another positive number also gives a positive value
The solutions are -4, 4
Hope this helps :)
