-x=-2-3
-x=-5
x=-5/-1
x=5
now substituting x=5
y=2x+3
y=2(5)+3
=10+3
y=13

Leyan bought 2 3/4 pounds of apples for $1.32 per pound, 1 1/2 pounds of peaches for $1.20 per pound, and some tomatoes, all from a grocery store. The total cost of his purchase was $9.63. . How much money did Leyan spend on tomatoes?
Answers
Explanation: First, we need to know how much was spent on apples and peaches.
The equation for the amount spent on apples is $1.32/1 lbs=$x=(2 3/4 lbs), where 2 3/4 * 1.32=$3.63
As for peaches, we have $1.20/1 lb=$x/(1.5 lbs), where 1.5 * 1.20=$1.80
Finally, $9.63-(3.63+1.80)=$4.20

A book has a front and a back and 200 pages.
The front and back cover are each 0.7 mm thick, measured to 1 decimal place.
Each page is 0.14 mm thick, measured to two decimal places.
Calculate the minimum thickness of the book.
Some working must be shown.
Answers
Answer:
28.3mm
Step-by-step explanation:
upper bound of front and back cover=0.75mm and lower bound=0.65mm
lower bound of page=0.135mm and upper bound=0.145mm
As there is a front and back cover we multiply the lower bound by 2
as there is 200 pages we multiply the lower bound by 200
(0.65*2)+(0.135*200)=28.3mm
The minimum thickness of the book will be 29.4 mm.
What is decimal place?A decimal point divides a decimal number into a whole number and a fractional component. The dot that appears between the whole number and the fractions is the decimal point.
The Upper and lower cover thickness are both 0.7 mm, respectively.
The Upper and lower thickness of the page are both 1.4 millimeters
We multiply the page thickness by two because there is a front and back cover. The page thickness is multiplied by 200 because there are 200 pages.
(0.7*2)+(0.14*200) = 29.4mm
Therefore, the thickness of the given book can not be smaller than 29.4 mm or 2.94 cm

Answers
Answer:
283
Step-by-step explanation:
15(18) + 12/3 + 9
270 + 4 + 9 = 283
Answer:
283
Step-by-step explanation:
First, we have the equation 15 × 18 + 12/3 + 9.
If we refer to PEMDAS, division comes first, then multiplication, addition, and subtraction.
So, the equation becomes 15 × 18 + 4 + 9.
Now, we can multiply 15 × 18 in the equation.
The equation becomes 270 + 4 + 9.
4 + 9 = 13.
270 + 13 = 283.
