Answer:
a) The algebraic notation is 4 ( x -3 ) = 4x -3
b) The algebraic notation is 2x +2
Step-by-step explanation:
<u><em>Explanation:-</em></u>
a)
Let 'x' be the number
Given 'x' is a number, subtract three
⇒ x - 3 and multiply '4'
The result of algebraic is 4 ( x -3 ) = 4x -3
b)
<em>Let 'x' be a number and add one</em>
⇒ (x+1) and then double
∴ The algebraic notation is
(x+1 ) (2) = 2x +2
Answer:
per one foot of aluminum foil it costs .62 cents
Step-by-step explanation:
there are 3 ft in a yard
so 3 x 3 is 9 which is the total amount of feat
then divide 5.58 by 9
5.58 /9 = .62
this means that per one foot of aluminum foil it costs .62 cents
Answer: $29.43
Step-by-step explanation: 3 shirts for $9 each adds up to $27. 9%= 0.09 so you can multiply the cost of the shirts by 1.09 because that is the base price plus the sales tax. Then you get $29.43.
Assuming she bought one pack of each and that’s all she can get.
She can make 42 arrangements with 4 balloons each:
2yellow
1blue
1red
(Having 28 red left over)
Good luck, again we are assuming she bought the balloons because it says “balloon packs come in”
Answer:
-2
Step-by-step explanation:
Using y=mx+c
ax+2y=10
Put y as subject of formula
2y= 10-ax
2y= -ax+10
using point (3,2)
2y= -ax+10
2(3)= -a(2)+10
6= -2a+10
Put a as subject of formula
-2a=10-6
-2a=4
a= 4/-2
a= -2
