All angles of the triangle should add up to 180 so if u add 95 and 14 you should get 109 then u subtract 180 and should get 71°

Answer:

71°

Step-by-step explanation:

95° + 14° = 109°

180° in a triangle

180° - 109° = 3rd angle = 71 °

Can anybody explain how to subtract mixed fractions?

Ilya [14]

Answer:

<em>convert </em>the mixed fractions to improper fractions (where the numerator is greater than or equal to the denominator): multiply the whole number part by the fraction's denominator, add that to the numerator, write the result on top of the denominator.
if the denominators are not the same, work out the common denominator and <em>rewrite </em>the fractions with the same denominators
subtract by subtracting the numerators and writing the result over the denominator
convert back to mixed fractions by dividing the numerator by the denominator, write down the whole number answer, write down the remainder above the denominator.

Example

$3\frac23-1\frac45$

convert to improper fractions:

$\dfrac{3 \times 3+2}{3}-\dfrac{1 \times 5+4}{5}=\dfrac{11}{3}-\dfrac{9}{5}$

common denominator = 3 × 5 = 15, so:

$\dfrac{11}{3}-\dfrac{9}{5}=\dfrac{11\times 5}{3\times 5}-\dfrac{9\times 3}{5\times 3}=\dfrac{55}{15}-\dfrac{27}{15}$

subtract:

$\dfrac{55}{15}-\dfrac{27}{15}=\dfrac{55-27}{15}=\dfrac{28}{15}$

convert back to mixed fractions:

$28 \div 15=1 \textsf{ remainder }13=1 \frac{13}{15}$

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The membe

Rzqust [24]

Answer:

The equation that represents the relationship between the number of T-shirts ordered, the number of colors on the shirts, and the total cost of the order is Y = $225 + X × $50

Where;

Y = The total cost of the order

X = The number of colors on the shirts

Step-by-step explanation:

The number of T-shirts required by the members of the school choir = 75

The amount charged by the printing company per shirt = $3

The charge for each color to be printed on the shirts = $50

The number of T-shirts ordered = 75

The charge per shirt = $3

The number of colors on the shirts = X

The fee per color on the shirts = $50

The total cost of the order = Y

Therefore, we have;

The basic cost of printing the 75 shirts = The charge per shirt × The number of T-shirts ordered

∴ The basic cost of printing the 75 shirts = $3 × 75 = $225

The total fee of the added colors to the shirt = The number of colors on the shirts × The fee per color on the shirts

∴ The total fee of the added colors to the shirt = X × $50

The total cost of the order, Y = The basic cost of printing the 75 shirts + The total fee of the added colors to the shirt

∴ Y = $225 + X × $50

The equation is therefore;

Y = $225 + X × $50.

What is the solution to the equation below log5(2x-3)=2

Komok [63]

Answer:

Step-by-step explanation:

Use the exponential form of this log equation. Rewriting this into exponential form gives us

$5^2=2x-3$

5-squared is 25, so

25 = 2x - 3 and

22 = 2x so

x = 11
