Grace uses a different way to divide 2.16 by 0.25 .She divides both the divisor and dividend by 0.01 to make an equivalent probl em with a whole number divisor is her work correct ? Explain
1 answer:
Answer:
8.64. Her work is correct
Step-by-step explanation:
Given the expression to divide 2.16 by 0.25
Dividing both expressions to a whole number by dividing them by 0.01 is true as shown;
2.16/0.25 = (2.16/0.01)÷(0.25/0.01)
(2.16/0.01)÷(0.25/0.01) = 216/25
216/25 = 8.64
Hence her value is 8.64 making her work correct

Answer:
x = 11.25
Step-by-step explanation:
4x=45
divide 4 from both sides
4/4 x = 45/4
x= 11.25
97.8ft^2 but if you round it to the nearest 10 it will be 100ft^2
The answer would be either:
Answer:
$6
Step-by-step explanation:
let x and y be the number of chip and pretzel bags respectively :
4x%2B2y%3 C=20
:
if x=1 then 4%281%29%2B2y%3C=20--->{{2y<=16}}}--->y%3C=8 :
if x=3 then 4%283%29%2B2y%3C=20--->{{2y<=8}}}--->y%3C=4 :
so chips 1 and pretzels 8 :
chips 3 and pretzels 4.
(f o g)(x)=f(g(x))
so
h(x)=f(g(x))
hmm, see the differences
x+7=g(x)+1
x+6=g(x)
g(x)=x+6
