Answer:
Step-by-step explanation:
a) 3x+2(41-5x)=33 as y=41-5x is given
3x+82-10x=33
-7x+82=33
-7x=33-82
-7x=-49 cut the negative signs as its LHS and RHS
<u>x=49/7=7</u>
b)-5x+3(3x-3)=3 as y=3x-3 is given
-5x+9x-9=3
4x-9=3
4x=3+9
<u>x=12/4=3</u>
<u>c</u>)4x+11-5x=9
-x+11=9
-x=9-11
-x=-2 cut the negative signs as its LHS and RHS
<u>x=2</u>
d) 5y+ -5-2y=-11 as x=-5-2y is given
3y+-5=-11
3y=-11+5
3y=-6
<u>y=-6/3=-2</u>
e)-5x-4(2x+1)=35 as y=2x+1
-5x-8x+4=35
3x+4=35
3x=35-4
3x=31
x=31/3
<u>x=10.3</u>
Answer:
In algebraic terms i guess this is what you mean 17% of x =27>14% of x
Answer:
2.42
Step-by-step explanation:
First you need to use two points from store b to find the slope (y1-y2)/(x1-x2). I chose the first two points. (15.54-25.9)/(1.5-2.5)= 10.36. After you take another point from store b to plug into the equation y1-y2=m (x1-x2). M is the slope we just found and I used the first point.
Y1-15.54=10.36 (x1-1.5) distribute the 10.36 to the parentheses.
Y1-15.54=10.36x -15.54 get y1 by itself
Y=10.36x so store b is 10.36 a pound and store a is 7.94 a pound. 10.36-7.94= 2.42
2/3 ÷ -1 1/3
2/3 ÷ -4/3
-2/3 × 3/4
-(2 × 3) / (3 × 4)
-6/12
-1/2
The answer is: -1/2 or -0.5.
The reciprocal of a number x is 1/x.
Let x = 1000
The reciprocal is 1/1000.
