Answer:
1/10≤x
Step-by-step explanation:
Lets write out the equation to make it easy.
4≥(-2x+1)*5
Lets distribute the 5
4≥-10x+5
Subtract the 5 from both sides
4-5≥-10x+5-5
Do the subtraction
-1≥-10x
Divide both side by -10
-1/-10≤-10x/-10
Divide
1/10≤x
There is a theorem which states that "If the areas of two similar triangles are equal then the triangles are congruent."
So, the longest side of Δ DEF will be congruent to ΔABC.
Longest side of Δ DEF ≡ Longest side of ΔABC.
Suppose in the diagram, the longest side of the Δ DEF is EF and longest side of Δ ABC is BC.
So, EF = BC
Since, EF= 25 units is given.
So, BC= 25 units.
Hence, longest side of triangle ABC is 25 units.
Answer: 8 weeks
Step-by-step explanation:
He originally had $315 in his account. This figure increased to $955. It therefore increased by:
= 955 - 315
= $640
If he deposited $80 every week, the number of weeks it would take to deposit $640 is:
= 640/80
= 8 weeks
Answer:
x > 15
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define inequality</u>
5x - 7 > 4x + 8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 4x on both sides: x - 7 > 8
- Add 7 on both sides: x > 15
Here we see that any value <em>x</em> that is greater than 15 would work as a solution to this inequality.
