Answer:

9 is your answer

Step-by-step explanation:

Remember to follow PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction). Remember to also follow the left -> right rule.

Solve:

8 - 2 x 3 + 7

First, Multiply -2 and 3 together

8 + (-2 x 3) + 7

8 - 6 + 7

Next, follow the left to right rule, subtract.

(8 - 6) + 7

(2) + 7

Finally, Add

2 + 7

9 is your answer

Given:

$\angle a$ and $\angle b$ are complementary angles.

$\angle a=32^\circ$

To find:

The measure of $\angle b$ .

Solution:

According to the definition of the complimentary angles, the sum of two complementary angles is always 90 degree.

It is given that, $\angle a$ and $\angle b$ are complementary angles. So,

$\angle a+\angle b=90^\circ$

$32^\circ+\angle b=90^\circ$

$\angle b=90^\circ-32^\circ$

$\angle b=58^\circ$

Therefore, the measure of $\angle b$ is 58°.

snow_lady [41]

Answer: $3,9$

Step-by-step explanation:

Given

A gym owner has purple and white weights that measure 10 kg and 6 kg each

respectively.

They weigh 84 kg in total

suppose there x purple and y white weights

$\therefore x+y=12\quad \ldots(i)\\\Rightarrow 10x+6y=84\quad \ldots(ii)\\\\\text{Solving }(i)\ \text{and }(ii)\\\\$

$x=3,\ y=9$

Thus, there are 3 purple and 9 white weights.
