If <em>x</em> = 4.338338338…, then

1000<em>x</em> = 4338.338338338…

and subtracting <em>x</em> from this eliminate the trailing decimal.

1000<em>x</em> - <em>x</em> = 4338.338338338… - 4.338338338…

999<em>x</em> = 4334

<em>x</em> = 4334/999

Answer:

Part 1) $BC=12.2\ units$

Part 2) $m\angle A=55^o$

Part 3) $m\angle C=35^o$

Step-by-step explanation:

Part 1) Find AC

we know that

In the right triangle ABC of the figure

Applying the Pythagorean Theorem

$AC^2=AB^2+BC^2$

substitute the given values

$AC^2=7^2+10^2$

$AC^2=149\\AC=12.2\ units$

Part 2) Find the measure of angle A

we know that

In the right triangle ABC

$tan(A)=\frac{BC}{AB}$ ----> by TOA (opposite side divided by the adjacent side)

substitute the values

$tan(A)=\frac{10}{7}$

using a calculator

$m\angle A=tan^{-1}(\frac{10}{7})=55^o$

Part 3) Find the measure of angle C

we know that

In the right triangle ABC

$m\angle A+m\angle C=90^o$ ----> by complementary angles

substitute the given value

$55^o+m\angle C=90^o$

$m\angle C=90^o-55^o=35^o$

A baker uses 4 cups of flour for each cake. He has 213 cups of flour in his shop. How many cakes can he make, and how much flour

➷ Just divide the values:

213 / 4 = 53.25

He can make 53 cakes.

53 x 4 = 212

Subtract this from the original:

213 - 212 = 1

1 cup of flour is left over

Answer:

x : -3

Step-by-step explanation:

1) 15x-3(3x + 4) = 6 (distribute -3 to the numbers on the inside of parentheses)

2) 15x - 9x - 12 =6 (combine like terms 15x-9x = 6x)

3) -6x - 12 = 6 (add twelve to both sides, add the 12 to cancel out the 12)

4) -6x = 18 (divide the -6 on both sides)

5) x = -3
