Answer:

The measures of two complementary angles are 63° , 27°

Step-by-step explanation:

The measures of two complementary angles are 6y + 3 and 4y - 13.

Sum of complementary angles = 90°

6y + 3 + 4y - 13 = 90°

10y - 10 = 90°

10y = 90 + 10 = 100

10 y = 100

y = 100/10 = 10

One angle = 6y + 3 = 6 * 10 + 3 = 60 + 3 = 63

other angle = 4y - 13 = 4 * 10 - 13 = 40 - 13 = 27

The angles are 63° , 27°

<h2><u>Solution 1</u> :</h2>

Cost of $1\frac{1}{3}$ pounds of gummy bears = $4.40

Cost of 1 pound of gummy bears :

$= 4.40 \div 1 \frac{1}{3}$

$= \frac{440}{100} \div \frac{4}{3}$

$= \frac{440}{100} \times \frac{3}{4}$

$= \frac{1320}{400}$

$= \frac{1320 \div 20}{400 \div 20}$

$= \frac{66}{20}$

$= \frac{66 \div 2}{20 \div 2}$

$= \frac{33}{ 10 }$

$= 3 \frac{3}{10}$

$= \color{plum}\bold{\$3.3}$

Therefore, 1 pound of gummy bears = <u>$3.3</u>

<h2><u>Solution 2</u> : </h2>

Cost of 1 pound of gummy bears = $3.3

Money Daniel has = $1.00

Quantity of gummy bears he can afford :

$= 1 \div 3.3$

$= 1 \div 3 \frac{3}{10}$

$= 1 \div \frac{33}{10}$

$= 1 \times \frac{10}{33}$

$= \frac{10}{33}$

$= 0.30$

Therefore, Daniel will be able to buy <u>0.30 pounds</u> of gummy bears from Jio.

Which expressions are equivalent to -6+4q+(-6q)

nlexa [21]

Answer:

-2 (q + 3)

Step-by-step explanation:

Simplify the following:

-6 + 4 q - 6 q

Grouping like terms, -6 + 4 q - 6 q = (4 q - 6 q) - 6:

(4 q - 6 q) - 6

4 q - 6 q = -2 q:

-2 q - 6

Factor -2 out of -2 q - 6:

Answer: -2 (q + 3)
