Answer: x=-10
Step-by-step explanation:
Let's solve your equation step-by-step.
6.2x+8=3(1.4x−4)
Step 1: Simplify both sides of the equation.
6.2x+8=3(1.4x−4)
6.2x+8=(3)(1.4x)+(3)(−4)(Distribute)
6.2x+8=4.2x+−12
6.2x+8=4.2x−12
Step 2: Subtract 4.2x from both sides.
6.2x+8−4.2x=4.2x−12−4.2x
2x+8=−12
Step 3: Subtract 8 from both sides.
2x+8−8=−12−8
2x=−20
Step 4: Divide both sides by 2.
2x2=−202

-x + 4y = -8
-5x - 4y = -16
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -6x = -24
- Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -x + 4y = -8
- Substitute in <em>x</em>: -4 + 4y = -8
- Isolate <em>y</em> term: 4y = -4
- Isolate <em>y</em>: y = -1
Answer:
the answer is 16
Step-by-step explanation:
if sixteen was added to nine it will be 25
Answer:
Step-by-step explanation:
For us,
P = 728,
r = .044,
e is Euler's number (a constant), and
t is 16. Filling in:
and
and
V = 728(2.02182385) so
V = $1471.89
Answer:
The lengths of the sides are 15 x 17 x 19
Step-by-step explanation:
Perimeter = 15 + 17 + 19
51 = 51
