Answer:
first method
<u>2</u><u>2</u>=<u>5</u>
7. x
we cross multiply to get
<u>2</u><u>2</u><u>x</u>= <u>5</u><u>×</u><u>7</u>
22. 22.
x= <u>3</u><u>5</u>
22
=1.59
second method
<u>2</u><u>2</u>=<u>5</u>
7. x
we multiply the denominators to get 7x
then we multiply each term by 7x
7x×<u>2</u><u>2</u> = <u>5</u>×7x
7. x
here the 7 and 7 will cancel out and the x and x will cancel out to get
<u>2</u><u>2</u><u>x</u>= <u>3</u><u>5</u>
22. 22
= 1.59
Answer:
700%
Step-by-step explanation:
The price increased from $0.30 to $2.40. What is the rate of increase, in percentage?
We can use the formula shown below:
Where
New Price is 2.40 and the Old Price is 0.30
We substitute and calculate:
Hence,
Price increased 700%
The variables are:
Matinee ticket ⇒ We can call this item as 'm'
Drink ⇒ We can call this item as 'd'
A bag of popcorn ⇒ We can call this item as 'p'
One matinee ticket costs 6.50
Two matinee ticket cost 2×6.50
Three matinee ticket cost 3×6.50
'm' matinee ticket cost m × 6.50 = 6.50m
One drink costs 5.50
Two drinks cost 2×5.50
Three drinks cost 3×5.50
'd' drinks cost d×3.50 = 3.50d
One bag of popcorn costs 6
Two bags of popcorn cost 2×6
Three bags of popcorn cost 3×6
'p' bags of popcorn cost p×6 = 6p
The expression for total cost is given by
Total = 6.50m + 3.50d + 6p
Answer:
-13 -i
Step-by-step explanation:
The first step is to find the sum
5-9i and -4+7i
Add the real parts and then the imaginary parts
5+-4 = 1
-9i + 7i = -2i
5-9i + -4+7i = 1 -2i
Now we subtract 14 -3i
1 -2i - (14 -3i)
Subtract the real parts and then the imaginary parts
1-14 = -13
-2i - -3i = -2i+3i = i
1 -2i - (14 -3i) = -13 -i
A line segment has a definite ending and beginning
