Answer:
12 3/8
Step-by-step explanation:
A = 2 3/4 x 4 1/2
best way is to change mixed numbers to fractions and multiply and then go back to a mixed number.
11/4 x 9/2 = 99/8 = 12 3/8
The answers are - 3 and 5.
Answer: the area of the triangle = 10.5 cm²
Step-by-step explanation:
Let 3x=a, 4x=b, 5x=c.
Hence,
P=2*(a+b+c)
36=2*(3x+4x+5x)
36=2*12x
36=24x
Divide both parts of the equation by 24:
1.5 cm=x
a=3x
a=3*1.5
a=4.5 cm
b=4x
b=4*1.5
b=6 cm
c=5x
c=5*1.5
c=7.5 cm

A. 2/3 * $60 = $40 spent on sneakers
7/10 * $35 = $24.5 spent on the sweater
5/6 * $45 = $37.5 on the jacket.
Together, you spend $102.
B. If you had saved no money, you would have spent 60 + 35 + 45 = $140.
140-102 = $38. You saved $38.
C. You saved

dollars, or
(c - 3)(2c - 1) is the factored form
