Answer:
26 = G. 27 = A. 28 = J
Step-by-step explanation:
26} A Nickle = 5 cents. A Dime = 10 Cents.
Way #1: 5+5+5+5+5+5 = 30
Way #2: 10 + 10 + 10 = 30
Way #3: 10 + 5 + 5 + 5 + 5 = 30
Way #4: 10+ 10+ 5 + 5 = 30
27} Pennies = 1 Cent. Nickels = 5 Cents. Dimes = 10 cents.
Way #1: 1+1+1+1+1+5+ 10 = 20
28} Pennies = 1 Cent. Nickels = 5 Cents. Dimes = 10 Cents.
Way #1: 10+5+1+1 = 17
Way #2: 5+5+5+11 = 17
Way #3: 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1 = 17
Way #4: 1+1+1+1+1+1+1+10 = 17
Way #5: 5+1+1+1+1+1+1+1+1+1+1+1+1 = 17
What aboout it? please clarify.
Step-by-step explanation:
Let age of rick = x
age of sara = y
age of marcos = a
age of jade = b
Rick is 4 years younger than Sara.
x = y - 4
Marcos is 3 years older than Jade.
a = b + 3
Rick's age is twice the age of Marcos and Jade's ages combined.
x = 2(a+b)
The youngest is 9 years old.
The youngest is jade because rick and sara are the parents and marcos is older than she is.
b = 9
How old is each??
a = b + 3
a = 9 + 3 = 12
Marcos is 12 years old
x = 2(a+b)
x = 2 (12 + 9)
x = 2 (21) = 42
Rick is 42 years old
x = y - 4
42 = y - 4
y = 42 + 4 = 46
Sara is 46 years old
Line 1:
Expanding the vertex form, we have
x² + 2·1.5x + 1.5² - 0.25 = x² +3x +2
Expanding the factored form, we have
x² +(1+2)x +1·2 = x² +3x +2
Comparing these to x² +3x +2, we find ...
• the three expressions are equivalent on Line 1
Line 2:
Expanding the vertex form, we have
x² +2·2.5x +2.5² +6.25 = x² +5x +12.5
Expanding the factored form, we have
x² +(2+3)x +2·3 = x² +5x +6
Comparing these to x² +5x +6, we find ...
• the three expressions are NOT equivalent on Line 2
The appropriate choice is
Line 1 only
Answer:
BE = 22.4 cm
Step-by-step explanation:
Δ CAB and Δ CDE are similar , then ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
8 CE = 128 ( divide both sides by 8 )
CE = 16 cm
Then
BE = BC + CE = 6.4 + 16 = 22.4 cm
