Answer:
-3(4c-2) -2c = -14c+6
Step-by-step explanation:
We need to find the equivalent expression for -3(4c-2) -2c.
First we open the brackets as follows :
-3(4c-2) -2c
= -12c+6-2c
=-12c-2c+6
=-14c+6
So, the equivalent expression is -14c+6.
3x - 10 = x + 4 <== ur equation
three times a number.....3x...with the x representing the number
ten less....3x - 10
is the same as...means =
that number (x) increased by 4....x + 4
so we have 3x - 10 = x + 4...
3x - 10 = x + 4
3x - x = 4 + 10
2x = 14
x = 14/2
x = 7....and that number is 7
Hey! Since there are three balloons that haven't been blown up, 1/4 of the balloons need to be blown up. Have a great day!
Step-by-step explanation:
x-6y=24
Isolate the Y variable
-6y=-x+24
y=(1/6)x -4
In this case, -4 is the y intercept. Plot a point on the Y-axis (0, -4)
1/6 is the slope. You go up one unit, and then you go right 6 units to plot your next point.

Answer:
x ≈ 28.2
Step-by-step explanation:
Δ CAB ≅ Δ CDE then corresponding sides are in proportion, that is
= , substitute values
= = ( cross- multiply )
28x = 18.7(14 + x) ← distribute
28x = 261.8 + 18.7x ( subtract 18.7x from both sides )
9.3x = 261.8 ( divide both sides by 9.3 )
x ≈ 28.2 (to the nearest tenth )
