5(x - 8) - 7 = 40
B)
5(8 - x) - 7 = 40
C)
7(x - 8) - 5 = 40
D)
7(8 - x) - 5 = 40
Answer : D 7(8-x)-5 = 40
The product of eight minus a number and seven equals forty when decreased by five
Let the unknown number be x
eight minus a number means 8 -x
For product we multiply
The product of eight minus a number and seven
It means the product of 8-x and 7
So expression becomes 7(8-x)
The product of eight minus a number and seven equals forty when decreased by five
To decrease by 5 we subtract 5
7 (8-x) -5 and this equals 40
So equation becomes 7(8-x)-5 = 40
It about linear equations
Answer:
plant 1 i think
Step-by-step explanation:
Answer:
Plant 2 grew faster
Step-by-step explanation:
The slope of plant 1 is 3
(each day the plant grew 3cm)
The slope of plant 2 is 5
(each day the plant grew 5cm)
The slope of plant 3 is 1.5
(each day the plant grew 1.5cm)
Step-by-step explanation: First equation: 3.4.1 3y + 7 = 4y
Subtract 3y from both sides: 3.4.1 (3y - 3y) + 7 - 3y = 4y - 3y
Simplify: 3.4.1 7 = 4y
Divide both sides by 3.4.1: 7 / 3.4.1 = 4 / 3.4.1 * y
Multiply both sides by y: 7y = 4 * 3.4.1y
Substitute 7y with LHS: 4 * 3.4.1y = 7 * Second equation: 3.4.2 10 - 3y + 4 = 8 + 4v - y
Add 3y to both sides: 3.4.2 (10 - 3y + 4) + 3y = 8 + 4v - y + 3y
Simplify: 3.4.2 17 = 12 + 4v
Subtract 12 from both sides: 3.4.2 (17 - 12) + 12 = 4v
Divide both sides by 3.4.2: 4.2 * 5 = 4v
Multiply both sides by v: 4.2v = 4 *
Generally, they are $1.69 apiece, and this week they are 4 for 5$
This means that this week, they are $1.25 apiece, meaning you spend less, by about $0.44
This weeks is cheaper by 44 cents
Answer:
Step-by-step explanation:
How to Solve
Given: Cost of 1 sparkling bottle last week = $1.69
This week's cost of 4 bottles is $5.
To find: The cost of 1 bottle.
For finding how much we pay less this week, we have to subtract the cost of 1 sparkling bottle this week from the cost of 1 sparkling bottle last week.
