Please help me I’m super confused on this problem!
Lorico [155]

Answer:

m < amc = 54°

Step-by-step explanation:

< amb and < bmc are complementary angles whose sum equals 90°.

Therefore, to find the value of 2x°, we must first solve for x.

We can establish the following equality statement:

< amb + < bmc = < amc

< 2x° + (x + 9)° = 90°

Combine like terms:

2x° + x° + 9° = 90°

3x° + 9° = 90°

Subtract 9 from both sides:

3x° + 9° - 9° = 90° - 9°

3x = 81°

Divide both sides by 3 to solve for x:

3x/3 = 81°/3

x = 27°.

Since x = 27°, substitute its value into 2x° to find m < amc:

2x° = 2(27°) = 54°

Therefore, m < amc = 54°

Answer expression 1:<br><br> 6 x 7 - 3^2 x 9 + 4^3
skad [1K]

In order to get the answer to this question you will have to use PEMDAS and solve.

6\times7-3^2\times9+4^3

Using PEMDAS:

3^2=3\times3=9

4^3=4\times4\times4=64

6\times7-9\times9+64

6\times7=42

9\times9=81

42-81+64

81+64=145

42-145

42-145=-103

=-103

Therefore your answer is "-103."

Hope this helps.

Which is a correct first step in solving 5 - 2x &lt; 8x- 3?
aliina [53]

Answer:

5 < 10x - 3

Step-by-step explanation:

Given:

The given inequality is:

5 - 2x < 8x- 3

The given inequality has variable 'x' on both sides of the inequality.

In order to solve such inequalities, we bring the variables on the same side as the first step in solving for 'x'.

Therefore, we could either add 2x on both sides or add -8x both sides to bring the variable terms on same side.

If we add 2x both sides, we get:

5 - 2x +2x< 8x+2x - 3\\5

So, among all the given options, third option matches the above inequality.

Therefore, the first step in solving the given inequality is 5 < 10x - 3
