HELP HELP HELP HELP FIND THE VALUE OF X

Mathematics
1 answer:
aalyn [17]3 years ago
8 0

Answer:

x=9

Step-by-step explanation:

The sum of all three angles inside a triangle is always 180 and the small square in the bottom left corner means that that is a 90 degree angle.

90+5x+5x=180

add the x values together

90+10x=180

subtract 90 from both sides

10x=90

divide both sides by 10

x=9

Help me please i jave 10 min left HELP​
yaroslaw [1]

Answer:

Option (A).

Step-by-step explanation:

8\frac{4}{5} is a mixed fraction and can be written as,

8\frac{4}{5}=8+\frac{4}{5} [Combination of a whole number and a fraction]

When we multiply this mixed fraction by 7,

7\times 8\frac{4}{5}=7\times (8+\frac{4}{5})

          =(7\times 8)+(7\times \frac{4}{5}) [Distributive property → a(b + c) = a×b + a×c]

          =56+\frac{28}{5}

          =56+5\frac{3}{5}

          =56+5+\frac{3}{5}

          =61+\frac{3}{5}

          =61\frac{3}{5}

Therefore, 7\times 8\frac{4}{5}=61\frac{3}{5} will be the answer.

Option (A) will be the correct option.

A scientist estimated that a mixture would need 4 milliliters of a chemical to balance. The actual amount needed was 7 millilite
Butoxors [25]

42.86% error was in the scientist's estimation.

Step-by-step explanation:

Given data;

Approx amount = 4 ml

Exact amount needed = 7 ml

Percentage error = \frac{|Approx-Exact|}{Exact}*100

Percentage\ error=\frac{|4-7|}{7}*100\\Percentage\ error=\frac{|-3|}{7}*100\\Percentage\ error=\frac{3}{7}*100\\\\Percentage\ error=\frac{300}{7}\\Percentage\ error= 42.86\%

42.86% error was in the scientist's estimation.
