Find the measures of angles a=(2x+3) and b=(2x-3),if their sum is 120 degrees
Ira Lisetskai [31]

Answer:

angle A is 63 degrees,

angle B is 57 degrees

Step-by-step explanation:

first, let's create the equation. Pretty simple, because angles a and b become 120 degrees when added up, this this will become:

2x+3+2x-3=120

now, we make it simpler. In this case, just add up the numbers that we can add up. this eventually becomes:

4x=120

now, all we need to do is divide 120 by 4, which becomes 30. So, x=30.

substitute the 30 into the x in the original equation, and this becomes:

60+3+60-3=120

63+57=120

thus, angle A is 63 degrees, and angle b is 57 degrees.

I dont understand this​
Yuliya22 [10]

Answer:

x intercepts there are three and y intercept in 0

Step-by-step explanation:

so  f(x)=a(0+3)(x-2)^2(x-2)

-2=a(3)(4)(-2)

-2=a(-10)

a=5

rewrite

f(x)=5(x+3)(x-2)^2(x-2)

Question:70% of x is 63. 1.Write an equation that shows the relationship of 70%, x, and 63. 2. Use your equation to find x. Show
a_sh-v [17]

"x" represents an unknown number, we know that 70% of x equals 63.

To calculate the percentage of a number you have to multiply the said number by the percentage, in this case, 70%, and divide the result by 100:

So the 70% of x can be calculated as:

\frac{70\cdot x}{100}=63

You can simplify this expression by solving the division

\begin{gathered} \frac{70}{100}x=63 \\ \frac{7}{10}x=63 \\ 0.7x=63 \end{gathered}

Then the expression that shows you the relationship is

0.7x=63

Using this expression you can determine the value of x, to do so you have to divide both sides of the equal sign by 0.7

\begin{gathered} \frac{0.7x}{0.7}=\frac{63}{0.7} \\ x=90 \end{gathered}

The value of x is 90
