Answer:
x=4
Step-by-step explanation:
4x-3=5x-7
-1x-3=-7 Subtract the 5x on both sides
-1x=-4 Add the -3 to the -7
x=4
Answer:
y = (-2/3)x + 5
2y=3x-6 Then divide by 2. y=3/2x-6 Now it is in slope-intercept form. The slope for this particular equation is 3/2 (m). The slope of a line that is perpendicular to this would be -2/3, the negative reciprocal of 3/2.

HOPE THIS HELPED!!!
For this you need to expand the brackets first:
3(2x+5)-4(2x-7) = 6x+15-8x-28
And then now you need to add and simplify:
6x+15-8x-28 —> 6x-8x= -2x
15-28= -13
So that leaves
-2x - 13
Answer:
5 1/4
Step-by-step explanation:
5 is the whole number so we up it aside.
Then we are left with 25/100,when we simplify that 25 into 25 is 1.
25 into 100 is 4 times.
Therefore we are left with 1/4.
I hope this helps :)
Answer:
3 x $10.50 = $31.50
Step-by-step explanation:
$10.50 + $10.50 + $10.50 = $31.50
$10.00 + $10.00 + $10.00 = $30.00
$0.50 + $0.50 + $0.50 = $1.50
$30.00 + $1.50 = $31.50
