Those are congruent so simply put 5x+12=6x-10
Pretty sure you can work out the equation

Answer:

Solution,

$5x+12=6x-10\\12+10=6x-5x\\22=x\\x=22$

Step-by-step explanation: They are equal because they are vertically opposite angles.

Hope it will help you.

I need this answer worked out 24.5 = - 2.5c - 4c

mote1985 [20]

24.5= −2.5c−4c
24.5=−2.5c + −4c24.5 = (−2.5c+−4c) 24.5=−6.5c 24.5=−6.5c
−6.5c=24.5
−6.5c − 6.5 =24.5 − 6.5 c=−3.769231
These are all the steps that you do to solve this equation. I worked it out fully and the answer is above these words.

EASY MATH!!! The formula F=9/5C+32 is used to convert Celsius to Fahrenheit temperature. A. Solve the formula for C B. The boili

puteri [66]

F=\dfrac{9}{5}C+32\\\\A.\\\dfrac{9}{5}C+32=F\ \ \ |-32\\\\\dfrac{9}{5}C=F-32\ \ \ |\cdot\dfrac{5}{9}\\\\C=\dfrac{5}{9}(F-32)

B.\\F=212\to C=\dfrac{5}{9}(212-32)=\dfrac{5}{9}\cdot180=100\\\\212^oF=100^oC

C.\\F=80\to C=\dfrac{5}{9}(80-32)=\dfrac{5}{9}\cdot48\approx26.7\\\\80^oF\approx26.7^oC

Can you help with did pretty please I'm stuck help just a, c ,d thanks luv.

Answer:

a) The slope of the function is 3.

c) The equation is represented by $n(t) = 3\cdot t + 35$ .

d) The y-intercept of the function is 35.

Step-by-step explanation:

a) According to the statement, we must assume that number of pieces of mail that must be hand-sorted (dependent variable) is represented by a linear function in terms of time (independent variable). That is:

$n(t) = m\cdot t + n_{o}$ (1)

Where:

$m$ - Slope, measured in number of pieces per minute.

$t$ - Time, measured in minutes.

$n_{o}$ - Initial number of pieces of mail that must be hand-sorted (y-intercept), measured in pieces.

$n$ - Current number of pieces of mail that must be hand-sorted, measured in pieces.

From Geometry, we know that a line can be formed by know two distinct points. If we know that $n(15\,min) = 80\,p$ and $n(45\,min) = 170\,p$ , then the following system of linear equations is formed:
