Answer:
x < -4
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define inequality</u>
-16x - 10 > 14 - 10x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 16x to both sides: -10 > 14 + 6x
- Subtract 14 on both sides: -24 > 6x
- Divide 6 on both sides: -4 > x
- Rewrite: x < -4
Here we see that any value <em>x</em> that is less than -4 would work as a solution.
They will have the same solution because the first equation of system b
is obtained by adding the first equation of system a to 4 times the
second equation of system a.
3/6 because there are six sides to a dice.

Answer:
Dawn has $1670 in account 1 and $1570 in account 2.
Step-by-step explanation:
Dawn can multiply the second equation by 8 and add 7 times the first equation.
8(3/8A +7/8B) +7(A -B) = 8(2000) +7(100)
10A = 16,700
A = 1670
B = 1570 . . . . 100 less than A
Dawn has $1670 in account 1 and $1570 in account 2.

3/8(1670) +7/8(1570) = 626.25 +1373.75 = 2000
Answer:
width = 5cm
length = 10cm
Step-by-step explanation:
1. the ratio is 1:5 so 50 metres in real life is 10 centimetres on paper so length = 10 cm
2. 25 metres in real life is 5 centimetres on paper so width = 5 cm
