Answer:
Step-by-step explanation:
Before number line can be drawn, there is need to find the value of x in the inequality given. Thus,
Divide both sides by 2
The number line is indicated in the attached picture.
3x + 10 = 5x - 4
14 = 2x
x = 7
measure of the angles is 3(7) + 10 = 31 degrees
this formula, doesn't rely on a product, relies on a "sum", or is namely an arithmetic sequence, aₙ₋₁ -3 is another way of saying, the value of the previous term minus 3, so it relies on the ordinal value of a term, so is an recursive formula, well, let's get it when n = 4.
Answer:
154π cm²
Step-by-step explanation:
Radius (r) = 7 cm
Height (h) = 4 cm
Surface area of cylinder
= 2πr (h + r)
= 2π (7) (4 + 7)
= 2π (7) (11)
= 2π (77)
= 154π cm²

Answer:
Let x be the unknown quantity of 50% silver.
Look at the silver concentrations... This will be 0.5x of actual silver,
Added to 5% silver in 500g or 0.05(500)g of actual silver
Totaling to (500+x)g of 20% silver which will have 0.2(500+x)g of silver
Your equation is:
0.5x + 0.05(500) = 0.2(500+x)
Solve for x to find the grams of 50% silver used
